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??
