I am very new to APM but not to quads. I am surprised to find that when I lift into the air the quad rotates fast (anticlockwise).
The control was set with right yaw to arm; left to dis arm.
If I reverse this I can effectively slow, stop and reverse the rotation (clockwise) by application of quite large right yaw stick inputs. BUT !!!
It will start to spin acw if I ease the stick and spin cw if I increase it. The neutral band is very narrow and way over to the right.
On the Mission Planner everything seems to be right but in the air (or on a polished floor) it surely is not.
At the field the roll, throttle and pitch controls seem to work well.
What have I done wrong ???
