My Vision 2 + flies on a straight course, but the whole quad points a little to the left, like it's crabbing into the wind. I've tried multiple IMU and compass calibrations, but haven't been able to correct it. While playing back the video later on, I can tell that the camera, while aligned with the body of the quad, is also pointing just a little to the left. After several seconds of straight ahead flight, the quad will make a small yaw adjustment to the right. I'm assuming that's the GPS bringing it back on course. It does that even when I don't have my left hand on the stick. When I fly in atti mode, of course, there's no yaw correction and the video is smooth. Anyone have any ideas how to correct this?
