I am running AC 3.1 RC7 on DJI Flamewheel 550.
Every time my Hexa Yaw hard with full cyclic and release there is a sudden throttle jump which results in increased altitude. I have rate YAW P(0.35), I(0.06), D(0). I am sure this is just a PID tuning issue, but not sure which one.
In what flight-mode?
Have you try Auto-Tune?
AC-3.1 has been released, why stick on RC7?
