I would highly recommend you buy This Kit if you don't have it already. It's useful not only in this project but almost all other things you build and it can save you from a lot of pain. I bought a kit like this and I have used it in almost every project I have made.
If you are into RC like me, I would also recommend these rechargeable batteries. It's great because whenever your controller runs out of battery you can just recharge them with a USB port. That means you can charge them from a computer, from a car or simply a regular wall adapter for phones. Much more convenient than going to the store to purchase new batteries and also more environmentally friendly.
This is a Bi Copter I made last winter which uses 2 thrust vectoring motors for stable flight. The copter serves as a good platform for learning about basic electronics as well as simple control systems.
REQUIERD PARTS:
Carbon fiber tubes 2 pieces, 15mm diameter approximately 25 cm length
2 motors (22mm) + ESC
Battery (3s 1200mAh - 2200mAh)
2 mg90s or sg90s servo (or similar)
Flight Controller
Receiver
Remote Control
Zip ties to attach parts
Steel wire for hinges
FLIGHT CONTROLLER: 30.5 * 30.5 FC has been tested but most likely works with many other sizes, for instance APM.
The main problems:
CoG too close to the thrust vectoring causing slow reaction
Too large propellers causing slow movement of motors
Flight controller did not use thrust vectoring angle proportional to thrust force
Flight controller sensitivity was too high
Potential solutions:
Lower CoG and raise motors
Use smaller propellers
Use trigonometry to calculate angle of motors based on force
Lower PID sensitivity
As you can see from the video it was not a complete success, however from a design perspective it was very educative. I learned a lot about how to construct moving parts using a 3D printer and also how to use affordable electronics for UAV applications.
The question now remains. Can you make it fly? Try building it yourself to find out!
