Just flew on airline with my P2V+ in custom case with gimbal lock in place, gimbal not touching any object in the foam well of the case. On arrival, everything looked fine, but the gimbal lock was off the gimbal, suggesting to me that the case may have experienced a stong bump at some point. The gimbal lock on first unpacking when I received the unit was never very tight. On first power up after the airline flight, gimbal is rolled to the left and not level when the P2V is on a level surface. In flight the gimbal responds appropriately and pitch is controllable via the app, and the roll corrects somewhat, but is never level when the P2V+ is level. Tried adjusting the center position of roll via the Assistant 2.20 software, but the gimbal does not seem to move when I type in values that should move it. I hope I am doing something wrong in Assistant, and that the gimbal was not somehow damaged in transit. Any suggestions are greatly appreciated.
