I would highly recommend you buy [This Kit](https://www.banggood.com/custlink/KD3GYHgc9h) 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! ###__Other Projects!__### * [SpaceX Modular Thrust Vectoring Device](https://www.thingiverse.com/thing:3149070) * [Swiff RC Three Wheeler](https://www.thingiverse.com/thing:3084009) * [MiniBird 130 Quadcopter](https://www.thingiverse.com/thing:2920006) Youtube: https://youtu.be/ULjg8tAcVYo https://youtu.be/lgAhRNhIt24 _{^{Made by Oliver Midbrink}}
