I'm having horizon issues with my new P3A. It's sometimes noticeably crooked when I get up to any appreciable altitude. It's not consistently crooked however. When I rotate the craft, sometimes this causes it to level out or even tilt the opposite direction. After I noticed it, I did do both an IMU and gimbal calibration which seems to have helped some, but it's still not perfect. Any thoughts? Try another calibration? This video is post-calibration: In the last minute, you can see it actually getting worse as I fly in. This is pre-calibration: (you can really see it in the last minute or so). Thanks!
