I've seen lots of threads about horizon issues, and they seem to be related but not quite my issue. My gimbal is wildly off horizon but ONLY in a single direction. I can correct it by spinning in a circle as you can see in the video, but if stop in that one direction it will slowly go back to slanted.
I've tried all of the calibrations, resets, and gimbal offset configureations mentioned in the other posts. Is this happening to anyone else?
Uploaded a sample to youtube so you can see what it looks like. Makes for totally unusable footage.
