    Hello,
    I had a crash with my Phantom. In effect the gimbal's arms was bent. I straightened them. Everything looked fine and seems working without problems.

    But after that my gopro is out of level and also I experience an unexpected tilt of the gimbal when phantom is rotating around its axis. It looks like this: http://youtu.be/fnGwRSNmoq0

    What I did:

    - IMU advanced callibration
    - Compass calibration
    - Reset gimbal with jumpers and re updated firmware

    Still the same situation, no improvement at all. My question: is there anything more that I can do with it? Is there possible it's not gimbal's fault, but problem is some part inside phantom?

    No one? Nothing? Any ideas?

    Yesterday I had some time and decided to thoroughly investigate the matter. Measured it all, all angles,
    distances and it looks like gimbal is perfectly straight. Horizon already straightened and during the test, I noticed quite a surprising thing.

    Earlier I thought it was a matter of curvature or damage the mechanism that switches mode to "FPV Mode" and the centrifugal force, which precipitated the distorted gimbal from its axis, but on the video http://youtu.be/t4h3_bs4ABM You can see that tilt occurs when you press the stick, gimbal then returns to its normal position despite a further rotation and the action of this force. It looks like to the rotation left/right gimbal mechanism adds lower arm up ... If not the crash, I would tell it's a software case...

    I have no more ideas. looks like I'll have to learn to live with it, because the only alternative the dealer offered me is shipping to DJI for a paid service, which I want to avoid.
