To avoid scratching your new airplane, do notunwrap the pieces until they are needed forassembly. Cover your workbench with an oldtowel or brown paper, both to protect the air-craft and to protect the table. Keep a couple ofjars or bowls handy to hold the small parts af-ter you open the bag.

Please trial fit all the parts. Make sure you havethe correct parts and that they fit and arealigned properly before gluing! This will assureproper assembly. EXTRA 260 - EP ARF is handmade from natural materials, every plane isunique and minor adjustments may have tobe made. However, you should find the fit su-perior and assembly simple.The painted and plastic parts used in this kitare fuel proof. However, they are not tolerantof many harsh chemicals including the follow-ing: paint thinner, C/A glue accelerator, C/A gluedebonder and acetone. Do not let these chemi-cals come in contact with the colors on thecovering and the plastic parts.

1) Using a modeling knife, carefully re-move the covering on to the pre-cut slot of fu-selage as picture below.

3) Slide the stabilizer into place in the pre-cut slot in the rear of the fuselage. The stabi-lizer should be pushed firmly against the frontof the slot.

2) Draw a center line onto the horizontalstabilizer. Then slide the horizontal into thefuselage.

Remove coverig

4) With the stabilizer held firmly in place,use a pen and draw lines onto the stabilizerwhere it and the fuselage sides meet. Do thison both the right and left sides and top andbottom of the stabilizer.

5) Remove the stabilizer. Using the linesyou just drew as a guide, carefully remove thecovering from between them using a model-ing knife.

When cutting through the covering to re-move it, cut with only enough pressure to onlycut through the covering itself. Cutting intothe balsa structure may weaken it.

6) When you are sure that everything isaligned correctly, mix up a generous amount ofFlash 30 Minute Epoxy. Apply a thin layer to themounting slot in the top of the fuselage and tothe sides and bottom of the vertical stabilizermounting area. Apply epoxy to the bottom andtop edges of the filler block and to the lowerhinge also. Set the stabilizer in place and re-align. Double check all of your measurementsonce more before the epoxy cures. Hold thestabilizer in place with T-pins or masking tapeand remove any excess epoxy using a papertowel and rubbing alcohol. Allow the epoxy tofully cure before proceeding.

2) Slide the vertical stabilizer into the slotin the top of the fuselage. The rear edge ofthe stabilizer should be flush with the rear edgeof the fuselage and the lower rudder hingeshould engage the precut hinge slot in thelower fuselage. The bottom edge of the stabi-lizer should also be firmly pushed against thetop of the horizontal stabilizer.

Remove covering.

3) While holding the vertical stabilizerfirmly in place, use a pen and draw a line oneach side of the vertical stabilizer where itmeets the top of the fuselage.

When cutting through the covering to removeit, cut with only enough pressure to only cutthrough the covering itself. Cutting into thebalsa structure may weaken it.

4) Remove the stabilizer. Using a mod-eling knife, remove the covering from belowthe lines you drew. Also remove the coveringfrom the bottom edge of the stabilizer and thebottom and top edges of the filler block. Leavethe covering in place on the sides of the fillerblock.

3) Do not permanently secure the receiverand battery until after balancing the model.

4) Using a 2mm drill bit, drill a hole throughthe side of the fuselage, near the receiver, forthe antenna to exit.

1) Plug the servo leads and the switchlead into the receiver. Plug the battery packlead into the switch.

2) Wrap the receiver and battery pack inthe protective foam to protect them from vi-bration.

3. Turn the airplane upside down. Placeyour fingers on the masking tape and care-fully lift the plane .

1) It is critical that your airplane be bal-anced correctly. Improper balance will causeyour plane to lose control and crash.

THE CENTER OF GRAVITY IS LOCATED83MM BACK FROM THE LEADING EDGE OFTHE WING.(See the photo).

2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing see the photo.

Accurately mark the balance point on the wingon both sides . The balance point is locatedback from the leading edge. This is the bal-ance point at which your model should bal-ance for your first flights. Later, you may wishto experiment by shifting the balance up to10mm forward or back to change the flyingcharacteristics. Moving the balance forwardmay improve the smoothness and arrow- liketracking, but it may then require more speedfor take off and make it more difficult to slowdown for landing. Moving the balance aft makesthe model more agile with a lighter and snap-pier ”feel”. In any case, please start at the lo-cation we recommend .

With the wing attached to the fuselage, allparts of the model installed ( ready to fly), andempty fuel tanks, hold the model at themarked balance point with the stabilizer level.

Lift the model. If the tail drops when youlift, the model is “tail heavy” and you must addweigh* to the nose. If the nose drops, it is “noseheavy” and you must add weight* to the tail tobalance.

BALANCING.*If possible, first attempt to balance the modelby changing the position of the receiver bat-tery and receiver. If you are unable to obtaingood balance by doing so, then it will be nec-essary to add weight to the nose or tail toachieve the proper balance point.

1) Completely charge your transmitter andreceiver batteries before your first day of fly-ing.

2) Check every bolt and every glue joint inyour plane to ensure that everything is tightand well bonded.

3) Double check the balance of theairplane.

4) Check the control surface.

5) Check the receiver antenna . It shouldbe fully extended and not coiled up inside thefuselage.

6) Properly balance the propeller.

We wish you many safe and enjoyableflights with your EXTRA 260-EP.

Ailerons : 25mm up 25mm down

Elevator : 20mm up 20mm down

Rudder : 25mm up 25mm down

1) We highly recommend setting up aplane using the control throws listed.

2) The control throws should be meas-ured at the widest point of each control sur-face.

3) Check to be sure the control surfacesmove in the correct directions.
