Just wondering if anyone has tried doing the auto gimbal calibration mid flight? I did this when my horizon was tilted and it actually seemed to correct it. I wasn't recording at the time and I only tried once, but I will try it again and post a video if it works the next time I try. It is raining right now but hopefully I can get out later. I am assuming this probably is not the fix as the phantom is probably NEVER completely level mid flight. Just in my one try it definitely leveled the horizon out.
