Hi everyone, I'm in need of some help. I recently had to send my phantom 3 professional into drone nerds for repair after a minor crash. The fella at the shop said nothing was actually wrong with the unit, he just had to reset the case because of some separation in the body seams. Anyway, since I've got it back I've noticed a pretty horrible horizon/gimbal tilt issue every time I start up the Phantom. I have completed 2 different IMU calibrations and a multitude of gimbal auto calibrations and I've been able to get the camera level, or very close to level with these routines. My problem arises when I shut the Phantom off and then turn it back on. When I turn it back on, my gimbal always defaults to being horribly tilted. I have had some success by auto calibrating the gimbal then repeatedly pressing C1 to alternate the camera between both extremes tilts. This resulted in a level to fairly level flight until last 30% of the flight. I'm pretty confused, so I thought I'd ask for some help. Thanks in advance!!!
