Hi all, My P3P is only a few weeks old and has just 8 flights on it. I did the latest firmware upgrade the other day and all went well, also did the IMU and gimbal calibrations straight after that. On the second flight after this I noticed the horizon was not level, not far off but not perfect so I tried the gimbal calibration again but get the following odd result where it calibrates to the left and right but then just drops loose like so: It does eventually very slowly creep back into the correct position but this can't be right surely? Never used to do this when I calibrated previously? It's never had a hard landing or crash. Any advice? Thanks!
