Hey, Some time ago I had an issue with high freq. pitch vibrations on 5208-75 (I was fighting with pids and LPF 2 weeks). On other roll and yaw I had ipower 5208H-200T and never had problem with it, so I decided to upgrade my cheapo pitch 5208-75 to new pitch ipower 5208H-200T..
After upgrading I noticed I still have vibrations on pitch motor, small when turn off and on gimbal and bigger when I tilt it up or down.
What can be an issue? I have only that issue on pitch - yaw and roll is perfect.
