Had my P2V+ replaced by the dealer. New one seems to be used as well. Markings on remote+P2 say CE. Yet it was set to FCC. Upgraded to latest firmware, got warnings about unstable compass in Phantom Assistant, did the compass dance, and all fine. It was on a table with steel tubes under the tabletop. It flew well, but before takeoff, then moving the drone around, looking at the gimbal tracking, I saw a few unexplainable jumps. On flight with video, I am flying straight, and then suddenly on the video, the camera/gimbal turns like 45 degrees left and back again. You can see the left leg. Please see this YouTube video: http://www.youtube.com/watch?v=YZ0YGDX2xJI Around 6-7 seconds it happens. I see it on the screen and gets confused, and stops flying shortly after, turning to get back. Is this normal ? What should I do ? Is it firmware related ?
