Hello all,
I encountered another problem with my P4P when rotating/panning the copter while it is in the air.
Holding the left stick a little to the left or the right lets the copter rotate slowly, but doing this in one position (without flying in one direction) lets the rotation become slower or even stop sometimes.
If I release the stick the copter rotates some degrees to the opposite direction, like being hold and released by a rubberband.
I never had this with my P3P before.

Does anybody else have this problem?!

Enable synchronized pan follow function was enabled in the gimbal menu, disabled it, problem gone.
