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 ???
Best wishes

I would double check that the props are turning in the right direction for their placement. I have found that the APM uses a different setup than other controllers.
Thanks Mathew. I am grateful for the input. The board in question appears to have been faulty. It is no longer working at all in the air, though it still looks ok on MP. I am a little surprised however by your comment about prop rotatation. I have another 2.5 Arducopter which is flying with the rotation: Front left and rear right; clockwise. Rear left, front right anticlockwise). It works well for me.
But somewhere in my early reading I did see a suggestion that it should be the other way. I feel confident that I either misread it or it was a typo. I think I am right in saying that the plan form I detailed in paragraph one, has been applied in all the Multiwii based X, I and H Copters.
Best wishes and thanks for the suggestion
