I was thinking this was all part of the compass issue, but now that that has apparently been fixed, I guess I am having a different problem. My Phantom 2 will hover, but when I rotate on its axis without moving the direction stick, it will drift in the direction it is rotating. This makes me totally uncomfortable when flying, since I always have to correct it, and when it has been rotating, there is that short moment that I don't know which way is forward. Is this a balancing problem that I am not aware of? I have the H3-3D Gimbal, GoPro, iOSD mini, transmitter and antenna attached to the bottom. I wasn't aware of any balancing I needed to do. Does anyone know about this, or had this issue? I looked in the forum but could not see it in the topics.
