I was looking at some video today and noticed when I turned my phantom the video wasnt quite as smooth as usual. I also noticed that when I am accelerating forward it looks as if the camera is tilted to the right a bit. What I mean by this is that the horizon is unlevel. I plugged it into assistant and couldnt find gimble settings. I thought I had seen a gimble setting tab in there at one point. As I had it plugged in I noticed that after moving the camera up and down using the gimble wheel that if I brought it back to the full upright position that it would slowwly begin aiming down. Any ideas?
