The GWS Slow Stick is an electric park flyer made by Grand-Wing Servotech. Its simplicity and easy-to-fly characteristics make it a great airplane for beginners. Out of the package, the Slow Stick uses three channels: throttle, elevator, rudder.With some simple modifications, ailerons can be added as a fourth channel to make a more nimble airplane

Introduction

SummaryT�he goal of the project was to construct a Micro Air

Vehicle based on the GWS Slow Stick Platform, with other parts designed in Creo Parametrics 1.0. It must be under 450 grams and capable of taking off and landing directed by a radio control A cost analysis and material list preparation made sure that the project followed the design specifications. The goal is to fly as many 8 paths around two pylons seperated by 50’ in 5 minutes. . For this, the plane must take off and land from the ground, be able to fly for the entire 5 minutes without needing to recharge the battery, and must stay within the boundary limits

Project: To be build and design a Micro Air Vehicle, under 450 grams, capable of taking off and landing directed by a radio control. surveillance capabilities

o Limits Rolling

Camera Mount

Needed to be:• Light• Strong (Unlikely to release)• Inexpensive• In a position where the camera can

see

Analysis-Trainer

• Night Vapor RTF• Ready to fly• Removable Landing gear• Weight: 16.4 grams• Wingspan: 14.8 inches• Recommended Battery: 70mAh 3.7V

14C

Includes:• Wing• Rudder• Horizontal/Vertical Stabilizer• Elevator• Wing supports• Gears and Wheels• Battery attachment• Fuselage (no shell)

Analysis- GWS Slow Stick

• 10 degree dihedral for extra stability• 5 Minutes of max power• 2.4Ghz CT6B 6-channel transmitter

and receiver was best for capabilities and cost

Analysis- GWS Slow Stick

Details

• Center of Gravity: Ensures that least amount of thrust is needed for takeoff• Securing Components:

Problems And Solutions

• Weight: The heavier it is, the more energy needed for thrust. (400 grams)• Battery: Only lasts 5 minutes• Propellor: Hair got stuck in the

propellor of the trainer• We had a very hard time with the

assembly, and could not find any battery in stalk that would work with out plane

Performance

We struggled with assembly and therefore did not get a chance to fly the Slow Stick
