I have noticed some instability in my shots since around the time I put a lens petal on. It seems that the horizontal line will shift like in FPV mode, but only slightly when I pan left or right. Has anyone else seen this? Do I need to turn up, or down the gain for the gimbal? I did not see you could do when I use the Phantom Assistant, do I need to plug in the gimball USB port to the PC to do this change?
