I've updated to the newest firmware, both aircraft and controller, and have been flying it the last couple of days just fine. This evening when I took it out, the gimbal is making a small jerking movement counterclockwise as you are looking at the display, then back. It wasn't doing it at all in the previous flights, I tried calibrating the gimbal, but hasn't helped, please help me troubleshoot this, as it is, the video is completely useless. Thanks!
