I had a similar issue about a month ago. I had taken off and was flying about four feet above the ground when for no apparent reason the P3P turned upside down and into the wet grass. I used the air compressor to clean as much water/grass as possible. I flew three more flights but on the third flight as I was about to land, the camera gimbal went berserk. The camera was still working fine. I discussed it with DJI and they finally told me to return it to them. I know it was received by them but I have heard nothing regarding the status. At the time I only owned one battery so I could not try that again. I did recharge the system but the but gimbal still did not work. DJI has had my machine longer than I have...
