I just updated the firmware of my P3A to v1.5, and it looks like my gimbal has a mind of its own. It's moving back and forth, rotating from top to bottom and side to side on a diagonal, and it jerks back and forth every half-second or so. Reading other posts, I tried calibrating the IMU, the compass, and the gimbal. Through all of this it just keeps jerking back and forth. I saw in another thread where someone suggested deleting and reloading the GO app, which I did with no success. I can post a video of what it's doing if that might help, or in case anyone wants to see what a screwed up P3A looks like. Perhaps it's time to open up the gimbal? Any suggestions?
