Sometimes you have to go “old-school” and just smack it up side of the head…
In 1967, I had an old Buick and the radio only worked when you smack the dash with your fist… When I was younger, we had an old B&W TV that sometimes needed a smack on it’s side to work… Might have been a loose tube…
I am glad you got it working… I still have a gimbal the jitters when I shoot a Globe (the 360° Photosphere…)
But as long as it works, I’m leaving it alone… It does not affect any photos or video and I only notice it when I am looking as the video feed as the drone moves left or right…
