This is a simple example of a drone that flies by itself, without utilizing any cheating physics.
It doesn't set it's own position to create the illusion of flying, and it doesn't `CreateForce` to itself to give itself a push in the right direction.
The drone is completely powered by the quad 'motors' at each of it's corners. The challenge when making this drone was to get it to fly to it's target position without overshooting or dropping to the ground.
The drone can also stabilise itself if it starts to shake around.
