Help! I have to calibrate my gimbal everytime I turn on my P3P, but worst than that is that I have to run twice the calibration to have an aligned horizon... I have tried: 1. IMU calibration and immediately gimbal calibration, failed 2. Unmount and remount the gimbal, failed 3. Tight the screw that is on the L arm, failed 4. Calibration during flight, failed 5. Call customer service, no answer. Emailing them, and they asked me to send my P3P for service, and wait 6 weeks... Please help!
