I just tried flying my P3 advanced in AT mode for the first time and found out that the bird instantly starts going backwards as I take off…rather fast too. Indoors as I power up it instantly leans over on the battery side and starts moving in that direction. I took it outside and experimented and realized it's doing the same thing in P mode only it corrects itself and comes back to its takeoff point. I had to break a prop to find this all out. The question is… What's going on? And can I fix it?
