Monocopter

This is a proof of concept demonstration that a flyer/helicopter/drone with the following contraints is possible: Only two rotors. All rotors on the same rotation axis. Weight distribution to change flight direction. Variable rotor speed for turning. I would say that the result is good enogh, but it would definitely need some improvements in term of self-correction to make it a good flyer :) The chopper can: Hover at a given height with limited wobble. Make itself upright when in the air if you don't press any key. Move in any given direction. Spin in place. The chopper cannot: Brake easily (you have to counter velocity yourself). Land very well. Recover if the blades are at more than 90deg angle. Recover after losing too much parts (especially the weights).
