i got a weird problem with yaw control like this:
- when yaw left, my quadcopter tend to move to the right side of copter
- when yaw right, my quadcopter tend to move to backward
note these happen in stab mode and loiter mode. in loiter mode, quadcopter move a large circle before return back to one position.
at first i thought it was my frame/motor/esc, so i switch to new frame/motors/esc, same issue!
also, change to kk2 controller did not have this problem.
i use external compass, and rise the compass & ublox gps 10cm separate to mag interference sources.
i think there is something need to improve in term of control algorithm.
