Its impressive to say the least. Most of the rotation (rolls) are done while the drone is "floating" through the air. Its almost like a free fall. drones are coming along way and i am looking to get a racer. the dynamics compared to a heli is different so they will fly different. When they figure an econimical way of using collective pitch it will be better again. They do have collective pitch units but these are too complicated and expensive to crash.
