HI all the problem is describe as below: In alt_hold mode ,the vehicle would overshot obviously when I let go my stick very quickly, after a high speed flight to left or right ,but this would not happen in Stabilize mode . Why ! Which parameters should I modify to help solving this problem? If I let go my stick of roll very gently , it would not overshot ,even after a high speed flight. I guess the reason for that if my frame is too light. After a hight speed flight the vehicle would climb normally , the alt controller have to reduce the THR_OUT to keep the vehicle from climbing .Once the THR_OUT been reduced ,the stb controller can't hold the fram stabile ,so it overshot !
