I just got my P3A back from DJI for stress crack repairs. They replaced the whole bird, which I wasn't expecting. I did a cold IMU and gimbal calibration and compass calibration before the first flight. This is a clip from my second flight with the new bird. The gimbal rolls left and right like it's on a boat. During this flight I tried adjusting the gimbal roll manually, but it wouldn't stay put. During this short clip it was in RTH mode and I was not inputting any commands with the RC. Has anyone ever seen this or had this happen to them? Any suggestions would be much appreciated...I really don't want to send it back to DJI for another 2 weeks.
