I've owned my MPP and flown it many hours since May, 2018. I have had no issues until recently, when during mid flight, the gimble began to go a little crazy from time to time. After returning home, I recalibrated to Gimble and IMU, which seemed to restore good operation. However, the issue has occurred several more times over the past two weeks. Today, when this occurred, the video shooting automatically shut off and will now only allow between 15 and 20 second shots. The camera is still providing great stills. The conditions at the time of the problem included some fog.All other functions seem to be working. Has anyone had a similar problem?
