Do ALL gimbals roll when yawed?

    Just sent a whole day flying with my newly installed tarot...and viewing the footage. I noticed when , in a hover and yaw-ing, that suddenly the horizon is tilted...slowing levels over 10-15 seconds. I can post footage if people want.

    So I took the bird in hand, powered the gimbal and rotated it much as one would do with a compass calibration. When yawed to the right the camera rolls to the right, yawed left rolls left....as opposed to stay level during the yaw. This appears to be to be a gyroscope effect. This roll would seem to create a very tilted horizon...for awhile....and be very difficult if not impossible to correct in post processing.

    Has anyone else noticed this? Do all gimbals do it??

    Had no problems with the zenmuse. Very happy.

    gimbal roll with Yaw is a common problem with many gimbals.
    the fix (at least with Arris) is to calibrate the gyro's.
    perhaps there's an option to do the same with the Tarot?

    Gizmo3000,
    Thanks for your insight and reassurance. Just got it installed and have not tackled the software/upgrade/calibration stuff yet, as well as the 7th channel tilt control. Yes, those are all there so I assume this is probably fixable.
