From the CockpitBy Gerry Yarrish

Icon of AviationI think the most famous WW II bomber was the B-25 Mitchell. Made famous by Jimmy Doolittle’s aircraft carrier attack on Tokyo, it set the stage to highlight the courage and bravery of America’s airmen. Several movies have followed the exploits of the Doolittle Raiders and in doing so, has kept the twin-engine B-25 medium bomber a popular aircraft for full-size and RC warbird enthusiasts.

This month’s cover plane is one of the newest B-25s to hit the market and the all-silver bomber from FMS is a great flyer. Distributed by HobbyKing, it comes with loads of details and takes a very short time to assemble. If you have ever watched Thirty Seconds Over Tokyo and have a soft spot for these iconic ocean-going bombers, then you’re going to love this warbird!

UPSIDE-DOWN AEROBATICS If you’re looking for more excitement to add to your RC bag of tricks, in this month’s “Aerobatics Made Easy,” columnist John Glezellis shares all you need to know to perfect the inverted circle! Nothing wows the crowd quite as much as inverted flight, and when you slow it down and precisely execute this move, everyone will take notice. Also in this issue, we have a good mix of micro RC fliers, including the new de Havilland Tiger Moth from Flyzone and an indoor micro coaxial helicopter from Blade—the Red Bull BO-105 CBcx. Both of these pint-size aircraft hold gallons of fun and are extremely easy to fly. Whether you like fixed-wing or coaxial-rotor flight, these reviews will give you the latest inside scoop.

MUSTANG FEVERI have loved the Mustang for years and I think your last issue with the P-51 from Hobby People on the cover was great. I know there are a lot of molded-foam warbirds on the market but many seem too big and require large motors and high-count LiPo packs. Most of my limited electric power experience has been with airplanes that have medium-size 11.1V LiPo packs, so fi nding a nice Mustang that can use my existing equipment is awesome! � anks for the timely review.Walter Watkins, email

Walter, the 49-inch Mustang from Hobby People is a nice size warbird that can be transported to the fl ying fi eld fully assembled in just about any compact car. With an excellent power-to-weight ratio and neat features like retractable landing gear and optional fl aps, you get a lot of value from this 3S LiPo-powered P-51. Equipped with standard Deans connectors, you can use just about any sport pack that can handle a 50-amp system. We also love the fact that the Mustang performs nicely with its scale-looking 4-bladed propeller. —GY

SPY IN THE SKYHaving already fl own the standard 1SQ quad from Heli-Max, I was pleased to read your recent review of the new camera-equipped V-Cam version. I had been wondering how the little quad would handle the additional weight of a video system, but it doesn’t seem to be an issue. Do you have any videos that were shot with your review model? Keep up the good work.Sammy Costello, Brooklyn, NY

Sammy, we had a blast putting the new Heli-Max 1SQ V-Cam through its paces. If anything, compared to the camera-less 1SQ, I thought it was even more stable. � is is perhaps because of the extremely slight weight increase. � e video footage is stored in a removable Micro SD card and you can easily download the fi les to your laptop. We combined the fl ight footage taken in the Model Airplane News offi ce with some other fl ight video and you can fi nd it at ModelAiplaneNews.com. —GY

PLANES ON THE BIG SCREEN!I just brought my family to the new Disney movie Planes. Wow! If ever there was a reason to go out and get an electric-powered airplane for some kit-bashing, this movie is it! I can just imagine all the Dusty crop-dusters and Skipper Corsairs that will be coming out of modelers’ workshops. I am on the lookout for a micro crop-duster model right now! � ought I’d share! Love your magazine.Bill Parkinson, Kingston, Ontario, Canada

Bill, thanks for writing. I agree, the new animated Planes movie should inspire some great characterizations for electric-powered RC. We happen to have a great makeover in the form of Rich Uravitch’s online post where he modifi ed a HobbyKing de Havilland Comet into the movie’s great British racer, “Bulldog.” I really got a chuckle out of the “Chupacabra” Gee Bee, but I think Disney missed a historical opportunity to properly name their Corsair character “Pappy” in honor of USMC “Black Sheep Squadron” commander Major Gregory “Pappy” Boyington. But that’s just my opinion. It was a splendid movie. —GY

MINI MICRO ACTUATORSI read with interest your review of the Ares Tiger Moth 75 from HobbyTown. I know all about micro servos but what are the actuators you mentioned in the article? How do they work?Frank Phillips, email

Frank, thanks for writing. Magnetic actuators go back many years and they produce semi-proportional control on extremely lightweight RC planes. A magnet is attached to the control surface and is positioned inside a fi xed coil of fi ne wire. � e coil is connected to the receiver board and when the transmitter stick is moved, the receiver changes the voltage sent to the wire coil. � is changes the magnetic fi eld around the magnet and causes it to move back and forth, which leads to the swinging of the control surface back and forth. � is control setup is practical only for lightweight indoor fl iers as the amount of force applied to the control surface is very slight. For the Tiger Moth, the actuator is only used on the rudder. —GY

Easy Wing Bolt RetainersTo help prevent losing your wing bolts, or leaving them in the workshop when you go to fl y, slip some snug-fi tting O-rings onto the bolts so they are retained on the bolt. � e O-rings provide some fl exibility to easily guide the bolts into the threaded block in the fuselage and are easy to remove should you need to replace the bolts. To make it easier to slip the O-rings over the threads, use a piece of a plastic drinking straw. Split it lengthwise, slip the O-ring onto the end, and slide the straw over the bolt. Hold the O-ring in place and pull the straw away. Tim Bourgeois, Tehachapi, CA

Cockpit Combing One of the things many scale modelers are faced with is trimming the edges of an open cockpit of a vintage airplane. Many use split fuel tubing painted black but for a really nice-looking treatment, you can use golf club grip wrap. � is is available in sporting good outlets or you can even remove it carefully from old clubs you fi nd at a fl ea market.Gene Oshrin, Southampton, NY

iPod Protector� ese days, we can get a lot of electronic reference material at the workbench: digital magazines (like Model Airplane News), along with how-to posts, photographs, and instructional videos from the Internet. � ough smartphones and tablets may have a screen protector, they are not really protected from spills and overspray. So, put the device in a sealed plastic bag; you can keep that reference handy without worrying about ruining your gadget with a spill of thinner or a drop of CA instant glue. Also, many touchscreens will work through the plastic bag. Warning: Don’t try this with devices that require ventilation for cooling (laptops, netbooks, and others).Sal Calvagna, Holbrook, NY

No-smell AcceleratorWe all know that CA glue is a standard in model airplane building; however, the use of accelerator can give some people a bad headache! � e problem with accelerator is inhaling the fumes. Instead of using the spray bottle, apply the accelerator with a cotton swab. Saturate the cotton with accelerator and apply it to the surface. � ere will be a slight smell, but no strong vapors to inhale. In fact, if you can do your heavy-duty gluing outdoors, you’ll do away with the strong odors all together!Joe Maran, Grovetown, GA

B-25 Mitchell PanchitoThis bomber makes a great first twinBy Rick Bell Photos by Peter Hall

Mention the B-25 Mitchell to any warbird fan, and they will most likely bring up the Doolittle Raid. While the attack on Tokyo on April 18, 1942, was the most famous B-25 mission, North American Aviation’s brilliant bomber played a much larger part in WW II. Designed as a medium bomber to operate from altitudes between 8,000 and 12,000 feet, the B-25 was powered by two 1,700hp Wright R-2600 engines and it served in every theater of WW II. The aircraft performed well and had a formidable array of firepower.

Author Rick Bell walks the B-25 Mitchell to the end of the runway for takeoff .



� e fi rst fl ights were made on our club’s well-mowed grass runway. As expected,

the B-25’s tricycle landing gear confi guration makes for easy ground handling. With full power, takeoff runs are surprisingly short, and on the fi rst fl ight, the B-25 leaped into the air in less than 20 feet! � at sure caught me by surprise! Future takeoff s were made with less power and were very realistic. While the B-25 is making a nice scale-like takeoff , retract the gear and watch the landing gear doors close — it’s mesmerizing! Landings should be made with some power on and the plane needs to be fl own all the way to touchdown. A gentle fl are about a foot off the ground will grease the plane every time. With confi dence-inspiring fl ight characteristics, the B-25 will remove any fears about fl ying a twin-engine model.

GENERAL FLIGHT PERFORMANCE Stability: � e B-25 has a moderate wing loading and this makes for a nice, solid feel. For the fi rst fl ights, I set up the model a little nose heavy on the forward side of the CG. After a couple of fl ights, I realized that the B-25 will easily tolerate a more aft CG.Tracking: With its counter-rotating props, there aren’t any torque issues. I only needed a couple clicks of right aileron and down-elevator to fl y hands off , straight and level.Aerobatics: While the B-25 is capable of mild aerobatics, it’s very much out of character. Rolls are very axial due to the counter-rotating propellers and do look pretty cool. Also, loops are easily done — enter with full power and gently pull up-elevator. Be sure to reduce power on the downside of the maneuver. Glide and stall performance: � e B-25 airframe has a fair amount of drag and will slow down quickly when power is reduced. I didn’t notice any snapping tendencies when the model stalled, just the nose dropping.

PILOT DEBRIEFING� e B-25 taxis well, thanks to its wide stance main gear and steerable nose gear. � e twin motors provide a lot of thrust and I had no problems taking off from a thick grass runway. � is is a standoff scale, twin-engine bomber, and I think it looks best fl own in a scale-like manner. Cruising at half-throttle provides a nice scale-like speed that looks perfect for a B-25. While aerobatic maneuvers are out of character for a bomber, loops and rolls do look pretty cool! � e best-looking maneuver is a nice low pass with the gear up and cycling the landing gear. Watching the gear doors open during these passes and then the landing gear dropping is just too much fun that guarantees to bring a smile to any pilot’s face!

In the Air

Shenzhen Famous Electronic Tech Co., better known as FMS, is one of the industry’s fastest growing RC airplane manufacturers. Known for their commitment to quality and innovation, the new Mitchell B-25 is no exception. It has a span of 57.9 inches, is constructed of durable EPO foam, and the Panchito is painted in brilliant silver and packs scale details including forward, rear, top, and side gun turrets with clear canopies and gunner fi gures. � e twin KV1000 motors provide strong power, great reliability, and smooth performance, while the main landing gear and nose gear use worm drive electronic, servoless retracts that feature sequential closing and opening doors. � is is accomplished with a very simple-looking circuit board that the retracts and the servos for the gear doors simply plug into. No fancy radio programming is required here and they look awesome in action! � ere are also bright LED navigation lights in the leading edge of the wing. While the wing panels are detachable for ease of transportation, I don’t recommend removing them once installed because of the large amount of leads (fi ve per wing panel) that need to be connected and stored. Access to the fl ight battery is through a removable canopy. Any intermediate pilot will be proud to add this warbird to their hangar!

Scale details are plentiful — here is the dummy radial engine and 3-blade fl ying prop.


FMS B-25 Mitchell Panchito

UniqUe featUresDistributed by Diamond Hobby, the B-25 comes extremely well packaged. The manual is nicely illustrated with photos and shows a logical assembly sequence. Also included is a 7-page manual that also covers the operation of the speed controls. Everything needed to complete the model is included — even a tube of glue and a screwdriver. However, I used some 5-minute ZAP epoxy as the supplied glue takes several hours to dry. Glue is only required for the attachment of the twin vertical fins to the horizontal stabilizer and the various dummy cannons, so a bare minimum of epoxy is needed. The model also comes complete with decals applied.

The B-25 assembles very quickly and without a lot of fuss. All of the servos are already installed and the control surfaces are hinged at the factory. This saves a lot of time, as there would be eight servos to install. The tasks you do need to complete are basic and go quickly. The tail assembly is first, and the control horns for the twin rudders and elevators need to be screwed to the control surfaces. This should be done before gluing the vertical fins to the stabilizer for handling ease. A clever array of pushrods and bellcranks actuate the twin rudders and elevators and they are pre-installed to the rudder and elevator servos on the underside of the horizontal stabilizer. After the vertical fins are glued to the stab, you only need to attach the rudder pushrods to complete the assembly. Before screwing the tail assembly to the fuselage, I tested the rudders and elevator and adjusted the pushrods to neutralize the control surfaces.

The wings are the heart of the model and require the most effort when it comes to assembly. The aileron servos are pre-installed and you only need to screw the control horns to the control surfaces and make up the pushrods from the included hardware. Like the tail assembly, I tested the ailerons before attaching the engine nacelles to adjust them. Now is a good time to check that the wing panels fit the openings in the fuselage — mine were pretty tight and required some sanding of the airfoiled section that fits into the fuselage. A couple of minutes of light sanding had the wings fitting perfectly. The wing uses two carbon-fiber wing tubes to attach the wing panels to the fuselage. Two built-in clamp assemblies in each wing panel provide a tight pinch around the tubes, and the screws to tighten the clamps are on the bottom of the wing. Before inserting the wing panels on the tubes, make sure the screws are loose, otherwise you won’t be able to slide the wing panels on. I really like this feature as it makes repairs or replacing a wing panel a snap.

The engine nacelles come ready to screw onto the wing panels, and the motors, 40-amp speed controls, cowls, retractable landing gear, and gear doors are all factory installed. You only need to snake the leads of all the components through the wing to the root and screw the nacelle to the appropriate wing panel. Before attaching the wing panels to the fuselage, hook up the receiver to the various functions to test the motors and make sure they are rotating (without the propellers attached) in the proper directions and that the retracts and doors

If I live to be 100 years old, I’ll never forget the feeling of sitting at the end of the runway, right hand wrapped around two throttles, looking out at 3,600 horses in two big radial engines. The 22,000 pounds of airplane around me agitated gently but noisily in their wake. I was about to fly the big, beautiful B-25 bomber! I was in the left seat of N543VT, a North American B-25N, Mitchell. Junior Burchinal, proprietor of Flying Tigers Air Museum, was in the right seat, shouting at me to do this and that. Yes, I’m multi-engine rated, but most of my limited experience has been in a couple of moth-eaten Apaches, and the B-25 bears as much resemblance to an Apache as I do to Raquel Welch.

Flying a 10-ton aluminum ingot isn’t something you just wander out to your local FBO and do. I was going through the WW II flight course at the Flying Tiger Air Museum in Paris, TX, and my original intent was to fly the fighters. The B-25 is also part of the program, intended to broaden your education — and it does, in spades! “Heavy” in this case means about 17,000 pounds empty, with an allowable emergency overload of nearly 45,000 pounds. That’s more than my hometown weighs!

Originally, I was to go up with Junior and drive the 25 around for an hour or so, just to see how it felt. I began to like the idea of flying the big moose, however, and I soon heard myself saying things about “more time,” and the words “type rating” kept popping up. Type rating! That’s the special license it takes to carry passengers in airplanes that weigh over 12,500 pounds, and the B-25 weighs that much with one wing and both engines removed. It takes a different type rating for each type of airplane. This also meant I would have to learn the airplane inside and out, and that’s a lot of territory. Junior is an FAA-designated examiner for the B-25, and I knew he would be tough. My first “introductory” flight made me feel like crawling into the bomb bay and going for a walk outside.

When we got up into the air and over the practice area, Junior signaled for me to take it. I took the wheel, and a slight out-of-trim condition caused the nose to drop. I automatically pulled the nose up — or at least I tried. I was flying with my left hand as my right rested lightly on the throttles. I could hardly pull the wheel back with one hand! I released the throttles and brought the other hand over to help, barely getting the nose up level. I finally had enough sense to wheel in some up-trim. I then made a turn to the left (or at least my hand did), but the control wheel resisted my attempts to move it. Grasping it firmly, determined to do it with one hand, I forced one end down and the wings responded smartly enough by rolling obediently into a left bank. Then the nose started to fall. With the 30-degree bank I was holding, I had to force the wheel to the rear to keep the nose from falling. It had started losing altitude the second I started to roll. I wasn’t prepared for the heavy control pressures.

Just to prove to me that the airplane would fly, Junior reached up and punched a red button on the console between us that started moving levers. As I was watching him, I saw the right propeller come to a stop, its blades edged into the wind. He diddled with some trim wheels and sat there, hands off, boring along with only one engine going. Satisfied that I had been suitably impressed, he fired up the other engine and headed back to his field.

work properly. After I confi rmed that everything was working appropriately, I attached the wing panels, fed all of the leads to the battery compartment, and plugged the leads to the receiver. Here’s where FMS really shines in my book — they supply the needed Y-harnesses and they are labeled so you can easily and correctly plug everything into the receiver. � ey also supply a harness that connects both motors together to use a single battery. From here, it’s only a matter of securing the receiver,

fi tting the battery, installing the 3-bladed propellers, adding the clear nose piece and dummy cannons to the fuselage, and balancing the model. All in all, it took me about two hours of eff ort to make the B-25 ready for fl ight.

BOTTOM LINE� e FMS B-25 Mitchell bomber from Diamond Hobby is a steal at $299.99. It is a highly detailed model that includes retractable landing gear, sequenced gear doors, lights, and pilot

and gunner fi gures, and all hardware needed to complete the model. � e assembly was quick and easy, and I love the sequenced landing gear doors! � e removable cockpit hatch provides easy access to the receiver and makes battery swaps a snap. I am impressed with the level of detail packed into this bomber and it is the center of attention on every trip to the fl ying fi eld. � e B-25 Panchito provides warbird thrills in a beautiful EPO foam package and sure looks great making low passes down the runway! �

Rudder and elevator control linkage are below the stabilizer.

Ready for another mission, the B-25 has plenty of detail including crew fi gures and machine guns.

Flyzone

Tiger MothA classic barnstorming micro flyerBy Gerry Yarrish Photos by Peter Hall

Flyzone’s micro airplanes are very well known for their stable, pilot-friendly flight performance and out-of-the-box great scale looks. I have flown and reviewed several of Flyzone’s WW I micro biplanes and all have been excellent performers in the gymnasium and outside in calm conditions. There’s virtually nothing to do except charge the battery (with the RTF versions) and link the plane to your transmitter (for transmitter-ready planes) to be flight-ready. Each comes in a nicely packaged box so they are safe and easy to store and transport. Whenever I attend a club indoor flight night, there’s never a lack of club members asking to fly my Flyzone planes.

Pilot Report

The de Havilland DH-82 Tiger Moth is just the ticket for relaxing afternoon flights. It’s ideal for committing micro aviation in a backyard, at a local park or indoors at any school gymnasium. Like other Flyzone planes, the Tiger Moth is available in two versions—a complete, all-in-one RTF package, and as a Transmitter-Ready (Tx-R) model that can be linked with any SLT transmitter, or a radio with an AnyLink module.

Unique featuresThe Flyzone RTF Micro Tiger Moth comes with a LiPo 140mAh flight battery and a charger built into the transmitter, an SLT transmitter, servos, speed control and receiver installed, and a basic Instruction manual. This review features the Tx-R version of the Tiger Moth and I linked it with a 6-channel TTX650 Tactic 2.4GHz

It takes only moments to get the Tiger Moth ready to fly.

The review model is a Tx-R (transmitter ready) version and it comes with the airplane and pilot figures, charger and a LiPo flight battery.

GENERAL FLIGHT CHARACTERISTICSStability: � e Tiger Moth is pilot-friendly and stable enough to be a great second airplane for anyone who has soloed RC successfully. Tracking: � e plane tracks nicely without too much need for rudder. Aerobatics: � is is a 3-channel (no ailerons) airplane and so it’s capable of loops, wingovers, and other vertical maneuvers. For me, the Tiger Moth is designed for low-level barnstorming in close to yourself. Stalls and Glide Performance: Power off , the Tiger Moth does glide but being a biplane, its nose needs to be kept pointing downward to maintain airspeed. Stalls are easy to recover from simply by releasing some elevator back pressure and adding some power. PILOT DEBRIEFING� e Flyzone Tiger Moth is ready to fl y straight out of the box. Charge the fl ight battery, and you’re good to go. Flight durations of about eight minutes are normal and the included charger takes about 20 minutes to recharge a partially used battery. Be sure not to full deplete the battery.

� e Tiger Moth performs nicely at my RC club’s fl ying

fi eld with calm conditions; it was a real joy to fl y! It is stable and has enough rudder and elevator throw making it easy to control. Even with the occasional gust, this little vintage era biplane easily rights itself with little control input (if you’re high enough). Even if you manage to hit the ground on occasion, the model is so lightweight that there rarely any damage. If the wind is blowing however, forget it. Flying off grass is not possible with any truly micro RC plane because of the small wheels—you need to hand launch it. If you are indoors on a smooth level fl oor, takeoff s are a piece of cake. � e rudder is eff ective and the Tiger Moth will become airborne almost all by itself. You can also make tight fi gure-8s and loops if you are daring and the ceiling is high enough.

In the Air



transmitter. The Tx-R Tiger Moth comes out of the box ready to go and will link to any SLT transmitter. Simply turn on your transmitter (place the throttle stick to the off position), and then power up the Tiger Moth by plugging in the flight battery. The only issue you might encounter is that with a 4-channel transmitter, the rudder control will be on the transmitter’s throttle (left) stick and the elevator control will be on the right stick. Using the Tactic TTx650 programmable transmitter, I simply used channel mapping to assign rudder function to the aileron stick, no mixing is necessary.

Above: The rudder and elevator control linkages have V bends in them for fine tuning the surfaces mechanically.

Below: The 1S 140mAh LiPo flight battery fits into an open compartment under the airplane’s nose.

de Havilland’s Answer to the Piper CubOld man de Havilland’s line of “Moths” goes clear back to the 1920s, a time in which they were on a par with their peers. However, as their peers advanced, the Moths continued to come from the cocoons with only minor mutations. Maybe an engine cowling change here, an engine mod there, but no sweeping design changes. The altimeter, marked in meters, speaks of a time long ago, and the horizontal floating compass betrays its nautical heritage. As I eased the thrust lever forward, I was greeted more by noise than anything else and we started rolling with no real sensation of acceleration. Just after I eased the tail up, the airplane gently lifted off and we hadn’t even rolled a half a dozen airplane lengths. I have tried several times to pick a single word to describe the Tiger Moth. The airplane is soft in all its movement and does nothing fast, especially climb. Finally, I opted for “leisurely” as the Moth is absolutely in no hurry. I cannot say I felt comfortable in the Moth. I’m used to a much more predictable, precise control feel as well as a machine that is less at the mercy of the elements. On final, I couldn’t decide whether my eyes or the airspeed was out of whack. To keep a decent airspeed number (50 knots), it required pointing the nose down at a ludicrous angle. When it was time to flare everything just plain stopped. We floated down close to the ground, hovered for a second, and plopped down, rolling forward just far enough to leave a short set of tire tracks in the grass. As an elementary trainer, the Tiger Moth was to the British Empire what the Piper Cub was to us. After the Canadians abandoned their Fleet Finches in 1942, the Moth was the only primary trainer the RAF and RCAF used. I now know why the English and Canadians call their airplanes “Kites.”—Budd Davisson/airbum.com

Painting Micro Pilot Figures One thing that you have to do to make your Flyzone Micro flyer look more scale, is to dress up the included all-white molded foam pilot figures included with the plane. I detail how I did this for my other Flyzone classic—the Fokker Triplane Check it out at ModelAirplaneNews.com/micropilotpaint

Having elevator and rudder control on the right transmitter stick is the goal (for mode 2 pilots). Once you have linked the Tiger Moth to your transmitter, be sure to check the control throws for proper function and direction. This also goes for the throttle so keep your fingers clear of the propeller and maintain a firm grip on the model when arming the motor. Besides charging the included 1S 140mAh LiPo flight battery, the only task left is to paint and install at least one pilot figure. Luckily, there are two unpainted micro pilot busts included with the Tiger Moth. J

An excellent transmitter to use for all Flyzone Tx-R airplanes is the Tactic 650 programmable 6-channel radio.

Fi 156 StorchAn exceptional flyer that’s priced rightBy Greg Gimlick

The Fieseler Storch was one of the most recognized planes to serve in the Luftwaffe, and it saw service in every German theater of conflict during WW II. Even today, it’s considered one of the best STOL designs of all time. Used primarily as an observation platform, it outperformed every Allied counterpart with its construction, reliability, and performance. Most notably, it excels in slow flight. Allied fighter pilots found it hard to engage and shoot down because of its slow-speed flight characteristics. As a sign of how great it was, Field Marshal Montgomery and Air Vice Marshal Harry Broadhurst both used captured Storches in North Africa and Western Europe for personal transport and observation.

Wing loading: 19 oz./sq. ft.Power incl’d: 3530 outrunner w/ 25A speed controlRadio req’d: 5- to 6-channel Price: $159.99



� e NTM 3530 motor and 10x6 prop provide lots of power for this little gem.

Taking off from a grass fi eld can be a challenge because of the small wheels, which is to be expected. I set mine up with the recommended control throws and center of gravity, and I haven’t made any changes to them over several fl ights. Access to the battery is easy using the removable windshield access and the aft access panel allows access to the receiver and tail surface servos. I have the fl aps set up for maximum defl ection and, for a plane this size, they seem very eff ective. A bit of elevator is required when deployed completely. I’ve fl own it using both high and low rates, but generally keep it in the high setting.

GENERAL FLIGHT PERFORMANCEStability: I expect a plane of this size and weight to be infl uenced by wind conditions, and it is, but it remains controllable with the assigned settings. I think the big legs on the gear help its upright stability by providing a CG lowering eff ect. � ere is very little, if any, dihedral in the wing, but the plane just feels comfortable in fl ight.

Tracking: It tracked beautifully, with no surprises in the air, and takeoff /landing runs were straight and true in spite of some diffi culty with our grass fi eld. � e rudder has plenty of authority to handle takeoff runs and I fi nd it’s best to ease into the throttle for a scale-like takeoff rather than just fi rewall the throttle. � e tail comes up quickly and ground track is solid with rudder.

Aerobatics: Nothing in the mission profi le of this plane says it’s aerobatic, but it certainly can be with the power of the NTM motor/prop combination on 3S LiPos. � e only thing that proved diffi cult in the aerobatic routine was inverted fl ight. It can be done, but it is not the easiest plane to fl y inverted and that led me to believe the gear design inhibits that. Loops, rolls, etc aren’t a problem and power is there for vertical climbs that are far from scale.

Glide & stall performance: Stalls were gentle and with the fl aps deployed, it looks like it’s going to stop before it actually stalls. � e nose dropped and it was recovered in the standard fashion. � e Storch has a nice glide angle and with a wing loading of 19 oz./sq. ft., it does a nice job fl oating around, especially if you use the fl aps.

PILOT DEBRIEFING� is plane hand-launches easily with more than enough power provided by the system, but if your grass is short, it will take off just fi ne. � is plane is well suited to a pilot who’s comfortable with a trainer. It just looks great tooling around the sky low and slow … just what the full-size plane was designed for!

In the Air

� e Durafl y Storch is small in stature, but huge in features. It is all built-up balsa and light ply construction, covered fl awlessly with matte camo covering. All of the electronics are installed, including the brushless motor and speed control. � e only thing you’ll need is a receiver to match your radio and an evening to assemble it. Anyone who has soloed and mastered coordinated fl ight can enjoy having this as an introduction to scale modeling — and it would be a very good introduction!

UNIQUE FEATURES� e fi rst thing that comes to mind when thinking about all the great features on this ARF is the method of retaining the wing. A 6mm carbon wing tube slides through the fuselage tube and into the wing receptacles in the usual

fashion, but that’s where the similarity ends. At the root of each wing is a drilled tab

that matches a slot on the fuselage. As the wing is slid into place and the

tab enters the fuselage, there is a latch that you pull down as

the wing is seated. Once the wing is fully seated against the fuselage, the latch lever

is released and the spring-loaded retaining pin rises up through the tab to hold it fi rmly in

� e ARF contents as they shake out of the box

� e cowl has been removed to show the pre-installed motor.

place. The wing is further secured with scale wing struts. Removal of the wing for transport only requires unplugging the servo wires, removing the lower strut screw, and releasing the latch inside the fuselage. It takes about a minute, if that.

Having all the servos pre-installed was a welcome sight. Unfortunately, on my review model, three of the four servos in the wing failed within seconds of plugging them in. A call to HobbyKing found that there had been a bad batch of servos that found their way into some kits. A new set of servos was quickly sent at no charge and I was assured the issue had been addressed in later kits. The level of customer service I received was excellent and rectified the issue without question. It’s a shame but stuff happens.

The list of notable features is impressive, especially at this price point! All of the control surfaces are hinged and although you still need to glue the tail pieces squarely to the fuselage,

it’s almost foolproof because of the interlocking stabs. The landing gear is pre-formed and only needs to be secured in place with brackets. There is no need to remove the cowl for any reason, but I popped mine off so you could see the motor installation. The covering and built-up surfaces are gorgeous, which is especially noticeable on the vertical fin. All of the markings are in place when it comes out of the box, and even the leading edge slats are scale in appearance.

ConClusion“Wow!” about sums it up. This is a scale airplane that flies well, looks great, and comes with all the gear you need (except a receiver and LiPo battery) for $159.99! It can be ready to fly in an evening of easy assembly. If you are going to fly from grass, expect it to flip over on landing. There is just no way around it unless you change to bigger wheels. The gear is beautiful, but the scale-size wheels are best for pavement or dirt. J

Up Close with Greg GimlickReviewer Greg Gimlick has been a longtime contributor to Electric Flight and is the “Ultimate Electrics” columnist for our sister publication, Model Airplane News. Here’s what he has to say about his involvement in “clean and quiet” RC power.

Electric Flight: How many years have you been flying electrics and are you exclusively electric now?

Greg Gimlick: I’ve been flying electrics since 1991 and although I’m primarily an electric flier, I still enjoy the occasional giant-scale gas project. Right now, I have 28 flyable planes and helicopters that are all electric. I also fly discus launch gliders.

EF: What’s your most important tip for keeping your electric power system operating properly?

Greg: This is easy — battery management! It’s a very simple process that many people ignore and it costs them unnecessary expense and aggravation. Here’s a simple recipe for keeping your electrics happy for a long time:

1. Use a balance charger whenever possible.2. Keep a log for each battery pack.3. Always use a 1C charge rate.4. Never store them fully charged or fully discharged.5. Always store them at 3.7-3.8 volts per cell.6. NEVER leave them in your hot car!7. Never leave them unattended while charging.Even if you don’t keep a log for each pack’s history, if you do the other steps, your batteries will serve you well for a long time.

SIG

Rascal 72 EGA popular design gets an electric makeoverBy Klaus Ronge Photos by Hope McCall

The classic ever-popular SIG Rascal 40 has gotten a makeover. Renamed the Rascal 72 EG, it now features added enhancements for electric power. The Rascal design originated in the 1950s, and SIG has been producing kits and ARFs in various sizes from small electrics all the way up to the 110-inch-span giant-scale model. The mid-size Rascal 72 EG is a convenient size, is easy to transport with its two-piece wing, and has good presence in the air. Designed for 2- or 4-stroke glow engines or equivalent electric power, the Rascal goes together quickly no matter which powerplant option you chose. Since I had the original Rascal 40, which was powered by a 4-stroke engine, I was excited to see how an electric version would compare. Some of the kit updates for electric power include a removable battery hatch and a removable cowl for easier engine/motor installation.

Field setup is quick and only takes a few minutes. � e battery hatch on the underside of the fuselage makes it easy to change battery packs. � e Rascal fl ies equally well on electric or nitro power, but I prefer the clean and convenient electric option. Ground handling is excellent for a tail-dragger with no tendency to nose over and can be described as trainer-like. It’s easy to keep the takeoff roll straight with the rudder and it is off the ground in under 100 feet. Landing is equally easy, simply decrease power and line up the Rascal on fi nal and fl are for a 2- or 3-point landing.

GENERAL FLIGHT PERFORMANCEStability: � e high-wing Rascal has excellent stability, yet is very maneuverable.

Tracking: � e overall tracking of the plane is very good. Turns look nicer when rudder is added either manually or by radio mixing.

Aerobatics: While you won’t mistake this for a precision aerobat, it is surprisingly agile. � e Turnigy G46 has more than enough power to pull the plane through the maneuvers. It can perform all the sport aerobatics such as loops, rolls, and stall turns. As the long wing results in a rather slow roll rate at the recommended control throws, get plenty of altitude and start a slight climb before attempting the fi rst roll. Increasing the aileron throw and adding down elevator during the inverted portion of the roll results in a nearly axial roll. Inverted fl ight requires only a small amount of forward-elevator pressure to maintain altitude. Once you become familiar with the model’s potential, aerobatics are fun and relaxing.

Glide and stall performance: � e Rascal can glide very slowly without any hint of tip-stalling. When the model is coaxed into a stall, it recovers quickly when the controls are released.

PILOT DEBRIEFINGAnyone who has mastered a high-wing trainer will have no diffi culty handling the easy-fl ying and forgiving Rascal. However, it has plenty of aerobatic performance to satisfy the more advanced pilots. � e vintage look of the model lends itself to low and slow fl ybys.

In the Air

� e Rascal 72 EG is available in either UltraCote transparent blue or red with white trim, allowing the fl awless laser-cut wood construction to show through. � e wing is in two pieces with an aluminum joiner and alignment pin. All the quality SAE hardware is more than adequate for this size plane and all is usable. A fi berglass cowl and wheel pants, wheels, molded windows, decals, fuel tank, plastic spinner, engine mount, and instruction manual are also included.

With its docile fl ight characteristics, the Rascal 72 EG would make an excellent second or third plane. While it is easy to fl y, it has a wide performance envelope, and seasoned fl iers will enjoy its sport aerobatic potential.

� e Turnigy G45 60A Plush speed control and 4S 5000mAh LiPo power the Rascal 72 nicely.

ONCE YOU BECOME FAMILIAR WITH THE MODEL’S POTENTIAL, AEROBATICS ARE FUN AND RELAXING.

UNIQUE FEATURESAs I unpacked the box, the quality of the construction and covering became evident. I used my heat gun to shrink the few wrinkled areas before beginning assembly. � e informative instruction manual contains plenty

of photos and construction tips, so even the fi rst-time builder should have no problems.

Assembly begins with the wing halves, which incorporate a separate aileron servo for each panel. � e servos are mounted on a molded hatch cover, which has a streamlined

for the speed control and LiPo battery. The electric version also requires slots to be cut in the fiberglass cowl for cooling air which is easily done with a Dremel tool. For extra cooling, I installed a vented 2 1/4-inch Tru-Turn e-spinner (tru-turn.com). I found that I had to extend the plywood battery tray aft to obtain the proper CG without adding any lead weight.

Installation of the tail feathers starts with gluing on the horizontal stabilizer after ensuring it is level with the wings and properly aligned. The rudder is hinged after installation using the provided CA hinges. A nice, high-quality tailwheel assembly is included, which uses springs to absorb the gear shock loads. The heavy-duty main aluminum landing gear bolts into place using the pre-installed blind nuts in the fuselage. The fiberglass wheel pants are very quick to attach and self-aligning. To attach the graphics, I wet the area where they are to be applied with glass cleaner to make them easier to position. I added a false cockpit floor and a Hangar 9 1/6-scale pilot figure (hangar-9.com) for scale effect.

ConClusionIt is easy to see why the Rascal family of planes enjoys such a devoted following. With its classic lines, elliptical wing and tail feathers, and docile flight characteristics, it makes for a relaxing and enjoyable day at the field. Don’t let the high-wing trainer-like appearance of the Rascal fool you; it has plenty of aerobatic potential, yet is forgiving for the novice pilots.

Tru-Turn Turbo Cool SpinnerTru-Turn has introduced a line of spinners designed for electric motor applications to assist in motor cooling. The spinner cone has a machined opening for cooling air and the backplate spokes are machined to act as a blower to direct cooling air over the motor. The spinner is available in assorted sizes and shapes up to 3 1/2 inches and requires an adapter kit (sold separately). Spinners can be custom cut for your prop at no charge and are available in several anodized colors as well as natural aluminum. These spinners will add a touch of class to your plane while increasing the performance and longevity of the power system. I really like the spinner I used on the Rascal and will use a Tru-Turn Turbo Cool spinner on my next electric plane.

fairing for the linkage. I was pleased to find that the ailerons and elevators were hinged and glued at the factory, but I gave them a good tug to make sure they were secure. For maximum control authority and precision I used Graupner DES 897 BB Metal Gear servos (graupner.de) for all the control surfaces. A string is installed in the wing halves to make it easy to bring the servo leads to the wing center section.

The installation of your preferred motor or engine is made much easier than the original Rascal 40 with the removable cowl. Detailed

Invasion of the multi-rotors! IRCHA may be a helicopter event, but this year “multis” were everywhere! From micro quads like the Heli-Max 1SQ and Blade Nano QX up to big professional-grade camera platforms with GPS navigation and capable of hauling large digital SLRs, there were multis everywhere you looked.

Acro isn’t just for “fish heads.” Mikado factory pilots put on a smooth and graceful aerobatic demo with a pair of really sharp V-Bar-equipped BO-105s. These large birds flew with real authority and looked great.

Helicopter JamboreeElectric news from the IRCHA flightline By Jim Ryan

For nearly any RC heli enthusiast, the IRCHA Jamboree is the highpoint of the year. For sheer size, it’s in the running with Joe Nall as the world’s largest RC flying event, and this year it drew 1,132 registered pilots. The vendor area is a heli pilot’s dream, where you can attend educational seminars, buy the latest products, or find out-of-stock spares for a trusted old workhorse. The competitions and industry demos at show center give you a chance to see the best of the best in action, and the informal parties at night top it all off. The event is so enjoyable that even non-heli flying RC’ers from all over the Midwest make the trip just to take it all in.

Israeli phenom Eitan Goldstin was a well-deserving selection for the

wildcard “Lucky 7” slot in “The One” competition. As Eitan flies, his spotter

preps his backup bird. The competition rules allow the usage of two helis to fill the pilot’s 7-minute slot, but this takes

fast footwork and coordination.

ElEctric HEli trEnds“IRCHA” is an event for heli pilots, but this year the explosion of popularity for multi-rotors was striking. These ranged from ready-to-fly micros to professional-grade systems with GPS navigation, laptop datalinks, and camera-mounting gimbals with inertial stabilization. In the middle ground are products that are nearly plug and play like DJI’s Phantom and Flamewheel. If multis are your thing, IRCHA is the place to be.

Bigger electric helis in the 700 and larger class have really become a major trend in 3D heli flying. These 12-cell machines have been around for a few years, but now they’ve caught on big with regular fliers. Just about all the major manufacturers now offer 700-class machines. Blade has entered this niche with their outstanding 700X airframe, and established 700-class players like Align and Thunder Tiger continue to refine and upgrade their veteran machines. Add excellent designs to the mix like the SAB Goblin, Mikado Logo, Gaui X7, and Compass HV7, and the only problem is which one to pick! There’s no shortage of power options for these brawny

Darrell Sprayberry’s scratch-built Sikorsky H-34 is a masterpiece. Pulled from Darrell’s own molds and with scratch-built mechanics, the 12-cell machine weighs nearly 40 pounds. Tail drivetrain issues kept Darrell from showing it off to best advantage, but he’ll surely have it sorted out soon.

Blade goes big! Blade RC has long been a big player in small helis. In recent years they’ve added 450, 500 and 550 machines, but now they’ve leapt into the 700 class with their excellent Blade 700X. Make no mistake: this is a serious entry in the 12-cell market, with features like direct cyclic drive and a tailcase CNC-machined from billet aluminum. I watched a number of impressive demo flights by the likes of James Haley and Jared Granzow, and this heli can do it all.

birds, with companies like Scorpion, Savox, Castle, and more all offering premium-quality motors for 12S power.

As big helis become such a growing segment, even the small 450-class birds that have traditionally been a major part of the

electric heli market are getting size and power upgrades. New releases like Gaui’s X3 and Compass’ Warp and longtime workhorses like Align’s T-Rex 450 and Thunder Tiger’s Mini Titan are now running 360mm blades and 4S to 6S power. The great thing is that this added capability comes at such affordable cost; Gaui’s X3 kit is available for under $200!

ElEctronic nEwsThe gear for electric helis just keeps getting better. High-capacity chargers, like Progressive RC’s iCharger line, offer ease of operation and the ability to parallel charge up to six battery packs at up to 30 amps. As a guy who goes back to the early delta peak chargers that could charge one NiCd battery per hour (and that battery capable of providing maybe five minutes of flight time), I feel like I’ve died and gone to heaven now that I can literally charge batteries faster than I can empty them.

In the electronic speed control world, Castle Creations’ outstanding Edge controllers have really raised the bar. These high-voltage speed controls are compact, easy to

The Gaui X5 is an excellent mid-size heli, engineered for high performance but tough enough to stand up to the occasional mishap. The simple design makes maintenance and repairs a snap. Here Mitch Marozas shows off the X5’s rock-steady handling down on the deck.

program, and offer improved data logging for performance diagnostics. Not to be outdone, Kontronik’s JIVE and Scorpion’s Commander lines have been upgraded for even better performance. As with heli airframes and motors, there’s no shortage of choices.

Flybarless systems have taken over the RC heli world, and these days you really have to look around to spot a mechanical flybar. Airframe manufacturers like Mikado, Thunder Tiger, and Align, and electronics specialists like bavarianDEMON (formerly HeliCommand), Futaba, BeastX, and Skookum Robotics all have outstanding units for fliers of all levels. Flybarless units on the market can be grouped into those that are directly programmed using buttons on the unit and the transmitter and those that are programmed via a laptop computer using a USB interface. I’ve programmed and flown a number of units in both camps, and it’s really just a matter of personal taste.

The most notable development on the electronic front this year was the huge growth of GPS autopilots. Just last year, GPS

Indiana Air Search and Rescue’s full-scale Huey was on hand for the event and selling rides to lucky attendees. There is just nothing quite like a Huey, and IASAR’s example is particularly well-maintained.

The premier competition of the weekend is “The One” event, with seven world-class pilots facing off to complete for a first prize including $7,000 in cash. This year Kyle Dahl and his Logo 700 topped the field with a truly outstanding and inventive routine. 3D competition just doesn’t get any better. IRCHA features some really impressive duet flights,

and here two Gaui factory pilots mix it up close-in with their 12-cell X7s. The heavy shift to bigger electric machines in the 700 class was even more obvious this year. Big just flies better.

IRCHA CompetItIonsIRCHA features some impressive competitions, with electric power a major presence in all of them. One of my favorites is the IRCHA Speed Cup, in which contestants fly their helis through a 200-meter course. There are several classes for wet and electric power, but the Electric Unlimited class is the one to see. Oliver Jellen traveled from Germany to take first in the Unlimited class, with his highly modified 14-cell TDR Velocity clocking runs up to 158mph! The sight and sound of these electric missiles is something any speed junkie would love.

The headline competition of the weekend is “The One” event, with seven world-class pilots competing for a cash prize of $7,000. This year, the five-judge panel of world-class heli fliers crowned Kyle Dahl as “The One.” Kyle’s flight routine was truly something to see, and his win was well-deserved.

stabilization was a real novelty, but this year they were everywhere, with DJI’s Naza and Wookong systems flying off the shelves. GPS stabilization isn’t just for aerial photography; sport helis and scale machines alike can really benefit from this added layer of safety and reliability.


JANUARY 2014 51

Curtis Youngblood’s Stingray is a quad with something different! This amazing bird has full collective pitch, making it fully aerobatic as CY demo

pilot Kenny Sierra shows here. The 2200-4S power train is belt-driven, and with very low blade inertia, the ’Ray is remarkably durable. Flight

stabilization is provided by a special version of the Total-G 3-axis gyro unit, and the performance really is mind-boggling.

As a natural fit with their outstanding line of Edge controllers, Castle Creations has rolled out their line of “Vertigo” motors for helicopters ranging from 450 to 700 size. The 700-size 4540 shown here is an 8-pole design with a 490Kv. Castle will be selling the Vertigos direct to fliers.

Sandy Jaffe’s MD-500 Explorer was one of the most technically impressive electric models flown at the event. Getting a NOTAR system to work properly is challenging, and yet Sandy’s machine showed absolutely steady tail hold even in gusty conditions.

The contests wrap up Saturday night with the hugely popular night fly competition. Night heli flying is an absolute blast, and the world-class competitors in this competition really raise the bar with their choreographed lighting systems and spectacular flying. This year, Bobby Watts topped the field with his very entertaining routine, but every competitor brought something truly different.

Next YearI no sooner get over the post-IRCHA daze when I start looking forward to the next year’s event, which in 2014 will take place August 6 though 10. Make your plans now!

Swiss master scale modeler Roland Kaufmann was a well-deserving

first place in the IRCHA Scale competition with his immaculate Alouette III. Believe it or not, this

15-pound scratch-built beauty is 25 years old and still flies with vintage Heim mechanics, now converted to

10S LiPo power.


JANUARY 2014 53

L ong before helicopters took over my life, I was fascinated with RC autogyros. For at least 25 years, I’ve watched the state-of-the-art progress from dual-rotor outrigger

designs to gradually more practical single-rotor versions. However, with all the other projects on the bench, I never got around to building one. With the Durafl y Auto-G gyrocopter, available in an ARF version for just $75, I fi nally decided to do something about that. Here was an autogyro I could have fl ying in an hour!

UNIQUE FEATURES� e Auto-G V2 comes almost totally assembled and includes some neat design features, chief among these a fl ex-drive to spin up the rotor for takeoff . � is drive plugs into the fl ight battery’s balancing plug, and it’s connected to a spare channel on the receiver, ideally a momentary switch like a push button. � e drive has a one-way bearing so that the rotor can uncouple in fl ight, and the drive shaft is fl exible to allow for tilting the rotor for roll control. � is should only be used prior to takeoff , as the rotor should freewheel in fl ight. Assembly is minimal, as the servos,

Gear UsedRadio: Spektrum DX7s (spektrumrc.com);OrangeRX 6-channel receiver (hobbyking.com); 4 microservos installedBattery: Nano-Tech 11.1V 1300-3S LiPo(HobbyKing.com)

I really had no idea what to expect from the test fl ight, which naturally took place on training/

club meeting night (no pressure here!). Initial takeoff was a breeze! I hit the switch to spin up the rotor and then cut the rotor as I added power. � e Auto-G accelerated smoothly, and I eased it off the runway. Once in the air, it handled much like a high-wing airplane: all fl ight controls were normal, and it showed no bad habits.

GENERAL FLIGHT PERFORMANCEStability: With its tall rotor pylon, the Auto-G has a natural tendency to level itself. I fi nd turns are better with a healthy amount of rudder. Autogyros won’t stall in the conventional sense, but you need to manage pitch and power to keep the rotor speed up. Don’t be afraid to shove in some down-elevator if you see the rotor getting slow.

Tracking: � is is one of the Auto-G’s most remarkable traits. Even on minimum distance takeoff s, with the rotor powered and full throttle, it tracks straight as a string. � is was really unexpected.

Aerobatics: Aerobatics are hardly the purpose of an autogyro, and yet the

Auto-G has proved reasonably capable. It does very nice chandelles and stall-turns and is even capable of loops. Do bear in mind that the rotor blades are not designed for high-G maneuvers, and you can crease the foam if you overstress them.

Glide and stall performance: While the Auto-G can do normal landing approaches like a regular airplane, the real fun is steep short-fi eld landings. Fly the traffi c pattern at what seems way too high altitude. After turning fi nal, pull throttle back to near idle and use down elevator to keep the rotor rpm up. � e Auto-G will sink like it’s on an elevator, but won’t pick up speed. About 10 feet above the runway, add a little power to arrest the sink and it will land like a butterfl y.

PILOT DEBRIEFING� is little gyrocopter exceeded my expectations in every way. � e powered rotor makes takeoff s a snap, and handing in fl ight is much better than expected. Landings are where the Auto-G really shines, and I can do touch-and-gos for as long as the battery lasts.

In the Air

electronics and motor are all installed. � e landing gear snaps in place, the horizontal stab mounts on the tail boom with two clamps, and the vertical fi n is glued in place with supplied glue. � e rotor blades are screwed to the hub, which has built-in fl apping hinges. Finally, the rotor and prop are mounted on their shafts. All that’s left is to install the pushrods and bind the receiver. It’s a good idea to put the fl ight battery on charge before you start assembly, as you’re likely to have the airframe fi nished before the battery is charged. With the minimal assembly completed, it’s time to head to the fi eld.

Highlights�+ Outstanding fl ight performance

�+ Quick and simple assembly

�+ Clever engineering details

� e rotor is mounted on a sturdy plywood pylon, and aileron control is via two micro servos in a pull-pull arrangement. � e motor drive uses a fl ex-shaft and one-way clutch to spin up the rotor for takeoff . Ideally, this should be assigned to a momentary switch, but a toggle will suffi ce.

� e installed 41mm brushless outrunner provides plenty of power for very short takeoff s. I do most of my fl ying below half-throttle, allowing fl ights of over 10 minutes.

The Auto-G is an odd-looking bird, but the flight performance is remarkable. Tracking on takeoffs is straight as can be, and handling is honest and predictable. The model has loads of power for short-field takeoffs but flies happiest around half -throttle.

Autogyros: A Different PAth to rotAry Wing flightFrom the earliest days of powered flight, ambitious designers attempted to build rotary-wing aircraft. In 1909, before he had built a successful airplane or even learned to fly, Igor Sikorsky built two unsuccessful helicopters. Given the incomplete knowledge of aerodynamics (and the limitations of structures and powerplants) true helicopters simply weren’t yet practical. Even Sikorsky, a man passionate about the possibilities of hovering flight, turned his attention to more conventional fixed-wing designs for the next 30 years. There was, however, a simpler middle road to rotary-wing flight. Just 10 years after Sikorsky’s unsuccessful attempts, Spanish engineer Juan de la Cierva began work on a rotary-wing concept in which the rotor was not powered but simply windmilled or “autorotated” as the aircraft flew through the air. With a freewheeling rotor there was no torque to deal with and no need to wrestle with the complexities of controlling cyclic and collective pitch. While not capable of true vertical takeoff or sustained hovering, de la Cierva’s “autogiro” showed important advantages over conventional aircraft. It could take off from short fields, fly safely at very slow speeds and could make extremely steep landing approaches with minimum rollout. Pitch and yaw could be controlled by conventional tail surfaces. After moving to England in 1925, de la Cierva steadily improved his designs, which were licensed to manufacturers around the world, including U.S. companies Pitcairn and Kellett. One major improvement was the development of direct rotor control—a forerunner of cyclic pitch control. Later designs could use engine power to spin up the rotor and then “jump” into the air. By the mid-1930s, the autogyro was well on the way to evolving into a true helicopter. Ironically, de la Cierva, who embarked on his autogyro designs in an effort to improve flight safety, died in 1936 in an airliner crash. It would be left to others to perfect the helicopter, but gyrocopters remain in use to this day as light recreational aircraft.

The Cierva C.6 was the world’s first truly successful rotary-wing aircraft, capable of cross-country flight. Based on the fuselage from an Avro 504, it used stubby wings for roll control. This photo shows how the rotor was spun up by men pulling on a rope, just like a toy top! (Photo via Wikimedia Commons)

The C.6 demonstrated full 3-axis control,and the Spanish press called its 7-mileflight in March 1924 “the leap into glory.”

X2X2Fly fast with authorityBy Charlie Hynes Photos John Reid

With the X2 out of ground eff ect, it steeled into a very stable hover with little stick movement needed.

T his is the high-performance X2 helicopter from Hobby People, which is a coaxial helicopter that is ready to fl y out of the box. � e only thing you will need to add

are four AA batteries into the included 2.4GHz transmitter. � e LiPo fl ight pack and AC charger are included and will take a few minutes to charge before getting into the air. Out of the box, everything is installed — even the main rotor blades and canopy. � e 2.4GHz radio system has switchable sensitivity depending on whether you’re fl ying indoors or outdoors and your skill level. You can also make it an extreme performer by adding brushless motors, aileron power assist, video housing with extended landing gear, a fl ight height limiter, or LED lights. All of these options plug into existing wiring (be sure to read the sidebar and learn how we added all the above accessories to showcase the stock and fully modifi ed versions!). Along with global service and support, this is a very nice package for someone wanting to get into the 350 class

Adding the brushless motor package will increase the fl ight range from 109 yards to 328 yards. � e fi xed-pitch coaxial rotor system stability is a given and this larger model is even more forgiving than some smaller helicopters. � is RTF model comes with a charger, a LiPo fl ight pack, and a transmitter that is already bound to the receiver. It’s suggested that you fi rst charge the fl ight pack with the included charger, and that fi rst charge took 15 minutes. During that time, I added the four AA batteries to the transmitter and read the manual. Within minutes, it was time to test fl y the X2. � e LiPo battery can only fi t into the helicopter one way. � ere were no straps to hold it in place, and just a fi rm push is needed to seat it in the cradle and allow the canopy to fi t. When connecting the large power connectors, the helicopter has to be on a level surface to let the gyro set properly. With the transmitter switched on, it takes a stick movement to full power and back down to low power to arm the speed controls. A beep comes from the transmitter when it is

of helicopters with little to no fl ying experience.� e height limiter is intended for beginners and the aileron assist is designed for advanced pilots, so you can buy the accessories to fi t your intended fl ying skills. With the video camera mounted under the heli, the optional foam and Velcro housing will protect your camera from the hardest of landings. UNIQUE FEATURES� is 100% factory assembled model can be fl own in a large indoor space or outdoors in wind up to 8mph. � e transmitter also has a switch to vary the amount of authority on the sticks so you can tailor the responsiveness to your surroundings or match the performance to your fl ying skills. � e automatic yaw gyro adds stable fl ight characteristics, and with composite plastic main and metal mainframe components, this bird comes out light and durable. An aluminum tail boom holds an Extreme Flyer’s patented Anti-Wind Tail Control System so that it makes contact with the chassis.

With the nose pointed in the wind, the X2 took off like any other helicopter, and what happened next was a nice surprise — it hovered hands off with little input. Sure, I threw the sticks around and it stabilized itself every time despite my eff orts to do otherwise. In no wind, it was able to fl y around me with ease and as the wind came up, it needed more forward stick to keep its spot over the landing zone or achieve forward fl ight. I did a few takeoff s and landings and each time, the little X2 impressed me with its stability and self-righting tendencies. As I watched it hover overhead, I noticed that the tail rotor was turning at times and at other times it was not. Being a fi xed-pitch heli, the X2 wanted to stay aloft even as the rotor speed slowed to a visible rotation, and its light weight and ample power allowed it to fl oat back into a nice landing every time. � is helicopter is a fi rst pilot’s dream. On initial setup of the brushless motor installation I had reversed the motor control wires going into the receiver and that rendered the gyro useless, causing the helicopter to spin like a top. If you have a similar problem, just swap the two leads into the receiver and everything will be resolved.

ready to fly. a quick test hop on the bench confirmed it was really ready to fly, but using the least sensitive settings proved to be a little less control than i like. i found that setting three suited me better indoors. if you are just starting out, it’s suggested to add the height limiter. The number on the display has no actual measurement, so some experimentation will be required to find the best number to keep this bird from hitting your ceiling (if flying indoors). For you advanced pilots, the recommendation is to have aileron assist. ConClusionit would probably take a beginner a few lessons with an experienced pilot by their side to feel comfortable flying this helicopter. For the experienced pilot, this bird has so much lift ability that carrying a 2-ounce Gopro camera would be fun and easy. on a first flight, i would recommend that you resist the temptation to hover a few inches off the deck and get at

POWER & PERFORMANCE ADD-ONSWe got all of the optional parts for the X2 to try out, including the brushless motors. It was a fast swap out with only four screws on the main frame holding the landing gear in place, and the provided screwdrivers are a perfect fit for the screws holding the motors to the aluminum plate. The upper motor requires the cage to also be removed with two more screws and the lower motor with the fiberglass spacer fit perfectly from the bottom.

After replacing the motors, I then attached the speed controls to the skids. Since the brushed motors unplug from the receiver, the new speed controls had to plug into the marked servo plug in locations.

The next accessories installed were the aileron assist fans. This went together a lot faster than I expected due to only one of them needing to be wired. The next accessories were the lights, so after plugging them into the matching red plug and powering it up, I was able to see which lights were which color. Placing solid lights and blinking lights in different locations is recommended, which I followed. But you can install them to suit what you like because there is enough slack in the wires to go either way. I used black electrical tape to secure the wiring but you could also use hot glue or zip-ties.

The next optional item I installed was the height limiter and again, the different plug was already wired in so getting them mixed up is next to impossible. The last optional item I added was the camera mount with a pre-cutout foam housing designed for a GoPro-type camera. An extended wire landing gear is included to keep the camera from getting damaged due to any rough landings. All of these optional add-ons make this helicopter a fun bird for the experienced pilot.

The wicked good looks are evident here with all rotors spinning it is quite impressive up close.

Here is the height limiter installed the numbers light up a bright red that can be seen in flight when it gets overhead.

General FliGht PerFormanCeStability: Stability is one thing you can count on with the X2 coaxial helicopter. With indoor flight becoming more popular, this is sure to be the helicopter that people will want to try indoors. tracking: on the X2, tracking it was very good, and the nose stayed where i wanted it to be at all times. The helicopter would buck and shutter at some of my control inputs, but just relaxing the sticks made these tendencies disappear.

aerobatics: This might not be one of the X2’s strongest points. This is due to the fixed-pitch and stable flight, which is what it was designed for. That being said, an experienced pilot can push the envelope to find this bird’s limitations.

Easy scale details for the Hangar 9 P-40B

Custom Corner

I n the last issue, we added a simple camoufl age color scheme to a heat-shrink-covered plane using inexpensive hardware spray paint. For the example here I used the Hangar 9 P-40B Warhawk, which you

can see in the before photo. Now we will add some detail work to the color scheme to make our conversion complete to the English version of this plane, the Tomahawk. We’ll add some new decals and panel lines to fi nish off this customization of the P-40 Warhawk, plus I will answer the red spinner question from last issue.

1� is is how the P-40B started out. While it is an actual scheme for a P-40B Warhawk, there is not much pop to this plane. I could not fi nd a B-version P-40 with camoufl age paint, so that is why I went to the other side of the pond for

my color scheme. � e British had a number of B-version aircraft to pick from, so I selected the one with the most graphics.

2I started out by applying the decals to the fuselage. I like to use glass cleaner when working with decals, that way I can lay the decal down and make any adjustments needed. Here I am using a soft cloth to press out any air bubbles

by starting from the middle and working out to the edge of the decal.

Here is my fi nished Kittyhawk ready for its fi rst fl ight in the new colors.

YOU’LL NEEDHere are some of the tools required to fi nish up the P-40 conversion. From left to right, the fi rst is the three-view drawing I used to lay out the panel lines, this is the same book from which I pulled the color scheme and aircraft marking. An assortment of extra-fi ne felt-tip markers, various size metal fl exible rulers with cork backing to protect the fi nish, and a laser level to lay out the fi rst panel line to be used as a guide for the rest of the lines. On the bottom is my sheet of custom-made vinyl decals. I had to order a minimum size sheet, so now I have many other markings made for future projects.

3I use a laser level to lay out the longest panel line on the fuselage. Notice that I level the fuselage to the line; once I have it where I want it, I make a couple of marks along that line that I will use as a guide for my longest ruler. The

nice thing about the laser line is that even over a compound curve, it will lay down a straight line, which is hard to do with even a flexible ruler.

Why the red spinner?Last month, I posed the question, “Why did the British put a red spinner on camouflage color scheme?” In my research, I could not find any definitive answer on that. But I did receive a couple of responses that are worth noting.

On the ground, a big red spinner means danger, keep away from my spinning prop. In the air, that big red spinner becomes a minute red object that doesn’t really hurt the camo job. —Beak, RF4b pilot, USMC, Ret.

No idea why the scheme was used, possibly to make the thing look more fierce than it was (generally, the Warhawk family had inferior performance to the opposition, especially at altitude) but it was only used in desert colors, not in European colors. —John Rutter (Britain), via Scott McKie

John is correct that the red spinners were on the desert birds and my color scheme is from the European theater. The true color of the spinner from the plane I copied this color scheme from was actually gray, the same color as the underside of the Kittyhawk. However, I like the red spinner and I can easily change it if I want to put it into a scale event.

4With my foundation line, the longest line is on the fuselage. I can measure from that one and using other fuselage features, such as the

canopy, lay down all of the other panel lines. I ended up using a gray felt-tip marker for all of my panel lines, which worked very well — I like the lines to be noticeable when you are up close to the aircraft.

5With the fuselage done, I moved on to the wing, following the same order by laying down the decals first. I used low-tack tape and accurate

measurements to mark the location of the wing symbols, so they match all sides. After laying them down, I removed the tape and again used the soft cloth to remove all the air bubbles.

6Again, I drew on my base (longest) line to use as a measurement point for all the other lines. I found that the marker would go dry after a line or two. I purchased three of them and would use one for a line, cap it, and stand it on

the cap, so the tip would be pointed down. Use the other one for a line and cap it the same way. This helped to make sure all of my lines were even.

7I used different drafting

templates to lay down the smaller panels and circles. These can be purchased from any stationary and department stores.

8Because this is an electric plane, there is no need to open up the air intake on the cowl, but I did want to paint them black. I used a fine-point black

marker to do the job and it worked perfectly. Using a felt-tip marker on this plane is fine, but it would need a clear coat of fuel paint if this were a gas or glow aircraft. A little note: if you make a mistake, you can clean off the marker line with a little rubbing alcohol.

Final thoughts I really like the end results and now feel that my plane has a little more color and style with the new layout. While I’m sure my design may not be 100% historically accurate, I have a plane that represents the one that RAF ace Sqn. Ldr. Peter Wykeham-Barnes flew in 1941.

Aerobatics Made Easy

M ost aerobatic fi gures contain multiple combinations of various individual maneuvers. Becoming an expert aerobatic pilot requires that you practice these individual elements before trying to conquer a more complex

stunt, and one great individual maneuver to become profi cient at is the “inverted circle.”

Flying an aircraft upside down can be challenging at times. Typically, this is due to the fact that to maintain altitude, you need to push on the elevator stick and apply down-elevator, which may seem odd at fi rst. Depending on the bank angle that is established at the start of the maneuver, rudder input is needed to maintain altitude, as higher bank angles require larger amounts of rudder. Like all things in life, though, these control inputs will become second nature with proper practice techniques.

As an example aircraft, we will take a look at the Eratix 3D from E-fl ite. It features a rather light wing loading, which makes it perfect for individuals who are new to the aerobatic world because a lighter wing loading gives a plane docile fl ight characteristics at low speeds and will give the pilot more time to react. As always, we will fi rst examine some programming techniques for the aircraft. We will then transition into the fundamental steps that will make you an expert at performing this stunt!

BEFORE WE BEGINFor a maneuver like the inverted circle, the “low-rate” settings that were recommended from the factory proved to have enough control throw. However, if your aircraft did not come with an instruction manual, start off with 15 degrees of control surface defl ection on all control surfaces.

If you are using a computer radio that off ers exponential, using it fully will prove to be benefi cial. Common on many radios, exponential softens how the airplane responds to a certain control input. For example, during the inverted circle, you may feel that you are only briefl y touching the elevator input to initiate the maneuver and the airplane responds more quickly than you’d like. Adding an exponential percentage to the elevator, in this case, will soften the plane’s response and make it feel smooth and more connected to your input. If you are unfamiliar with using exponential, please only add this percentage in small amounts. � en, take to the skies and pay special attention to how the aircraft responds.

Now that the control throw and exponential values are set, let’s take a look at the center of gravity. For a maneuver like this, if the plane’s center of gravity is too far back, it will have a tendency to climb while inverted. � is fl ight characteristic is highly undesirable for consistency as the airplane will become rather unstable at times. If this is the case, shift the fl ight battery forward in small increments until the airplane reacts exactly as desired. I like to fl y parallel to the runway at full power and then roll the airplane to inverted to take note of the tracking. If the airplane dives slightly, the center of gravity is perfect. If it dives excessively, it is nose-heavy and the fl ight battery should be moved rearward. On the other hand, if it climbs, the fl ight battery should be moved forward as the aircraft is tail-heavy.

Fly the Inverted Circle Four easy steps to master this fun move

By John Glezellis Illustrations by FX Models

ENTRY: Enter in straight and level fl ight.

INVERTED CIRCLE OVERVIEWWith the aircraft fl ying upright and parallel to the runway at a moderate speed, perform a half-roll before it passes you. � en input a little aileron to initiate the bank followed by down-elevator to start the circle. You’ll need to vary the amount of elevator and aileron input to maintain a constant bank angle and altitude. It is important to reach the cardinal points of the circle, and some rudder input may also be needed to keep the turn coordinated (i.e., keep the nose of the aircraft in the turn). Once the airplane is directly in front of you and has completed the 360-degree turn, it can be rolled to upright level fl ight. Now, let’s divide this stunt into four separate steps:

STEP 1. Orient the aircraft so that it is parallel to the runway and approaching you (a.k.a. the “center” position). At about 100 feet before the airplane reaches center, apply 60% power and begin the half-roll to inverted fl ight. In this example, a left half-roll will be executed, so a touch of left aileron will be applied to roll the airplane inverted.

1 While maintaining altitude, execute a half

roll to inverted fl ight.

I LIKE TO FLY PARALLEL TO THE RUNWAY AT FULL POWER AND THEN

ROLL THE AIRPLANE TO INVERTED TO TAKE NOTE OF THE TRACKING. IF THE

AIRPLANE DIVES SLIGHTLY, THE CENTER OF GRAVITY IS PERFECT.

EXIT: Exit straight and in level fl ight at the same altitude and heading as the entry.

STEP 2. When ready, bank the airplane by applying a touch of aileron input. Since the airplane is travelling from left to right and rolling left, bank it 15 degrees and then input elevator to start the circle. After the fi rst cardinal point is met, the nose of the aircraft should be pointed out 90 degrees from where it began. Apply elevator and aileron input to maintain a constant bank angle and to maintain altitude until the second cardinal point is met.STEP 3. Now the maneuver is 50% complete! Continue a constant bank angle and apply throttle as needed to maintain airspeed. For the best aerobatic presentation, constant speed is mandatory! Also, depending on the bank angle of the aircraft, rudder input may be needed to maintain altitude. STEP 4. As the airplane approaches the last cardinal point, it should be directly in front of you. At that point, roll the airplane to inverted fl ight by applying a touch of aileron input in the opposite direction of the bank. � is will get the airplane back to inverted fl ight and parallel to the runway. � en you can either stay inverted or perform a half roll to upright level fl ight.

Like all maneuvers, proper practice is mandatory. A maneuver like the inverted circle can become somewhat tedious as the orientation of the airplane may become diffi cult at times for the aerobatic newbie. Most will experience some orientation issues when the aircraft nears the 75% completion point as the airplane will be headed toward you. At this point, it is important to know proper roll directions and what elevator input is needed to maintain altitude. Keeping the airspeed somewhat low and having a generous amount of altitude is benefi cial and will give you time to respond to various corrections that may be needed.

FINAL THOUGHTSYou have now learned how to not only properly program and set up your plane, but also how to perform the inverted circle. When you’re familiar with your airplane, its orientation at all stages of the maneuver as well as the inputs needed, you can bring the maneuver down to just inches from the ground at higher speeds to really impress the crowds — inverted fl ight is always a show-stopper! �

ADave Perrone’s Giant Flying RazorA super-detailed Fokker D.VIII

TailviewBy Gerry Yarrish

As we near the end of the flying season in New England, there are two events in New York that draw some pretty impressive models. They are the WW I Jamboree at the Old Rhinebeck Aerodrome and the NEAT Fair in Downsville. Someone I bumped into at both events was expert WW I scale modeler and RC pilot Dave Perrone of Pittsfield, MA. Dave was flying his beautifully executed WW I Fokker D.VIII parasol fighter. Dave and I chatted, and here’s what he had to say about his impressive "flying razor."

Tell us a little about your impressive aircraft.I wanted something new since I have been flying my 1/3-scale Fokker D.VI for a couple of years, and the D.VIII was on my list of planes to build. It is a Glenn Torrance Model (GTM) design and it is also 1/3-scale. It has a 114-inch wingspan, is 78 inches in length, and weighs about 28 pounds with batteries. The fuselage is built using hardwood dowels for the framework and I tried to use the same design and building techniques that were used on the full-size D.VIII. Similar to the full size, the wing is sheeted with thin plywood and finished with stain from the Schimek Holzbeize company in Austria. Back in 1918, they supplied the same stain to the Fokker Aircraft Company and are from the original aircraft’s bill of materials! The pattern is of Echim Engel’s reproduction aircraft. I covered the stain

with several coats of clear shellac and a final sprayed-on coat. The fabric is GTM 4-color lozenge covering, which really brings out

the model’s scale look. It’s sewn together into panels and applied with Aleene’s fabric glue and finished with Randolph clear nitrate and butyrate dope.

What is the power system and radio setup?I did not want to do a lot of experimenting, so I copied the same setup I have in my Fokker D.VI biplane. The D.VIII has an AXI 5360/20 brushless motor spinning a 30x20 prop. Power comes from a 12S LiPo (two 6S 5000mAh packs in series) battery, which is managed by a Castle Creations HV 85 speed control. This setup easily provides over 10 minutes of flight duration.

I use a Futaba 10CAG transmitter with 3305 Futaba servos and two receivers, one in the wing for the ailerons and one in the fuselage for rudder, elevator, and throttle. I did this to eliminate any visible servo lead wires along the cabane struts.

Now for the big question — how does it fly?The maiden flight was several weeks back and it flies like a trainer and in 1/3-scale, the model performs much better than my 1/4-scale D.VIII. There’s plenty of power on tap and it takes only 30 or 40 feet to become airborne. It presents itself well in the air and has less of a tendency of bad ground handling or ground looping. The plane lands very nicely; again, with no bad ground habits during the runout.

Dave's Flying Razor is detailed inside and out. Here you see the stained plywood finish of the wing and the machine guns.

Caught on the flightline at the NEAT Fair, Dave shows off his impressive 1/3-scale Fokker D.VIII. It is a Glenn Torrance Models' design.
