My P4 has had this issue for a while. The video is usually rock solid, but every once in a while there is a tiny jerk that makes the video unusable. I am having a difficult time trying to figure out which axis is causing it. I can't replicate the glitch on the bench when it's not flying. Here's a video clip of the issue. Which axis do you think is causing this?
