I see similar posts but nothing quite like this. I have been flying the Inspire 1 Pro X5 for a year now and clocked up close to 40 hrs flt time. But never seen this problem before. The Inspire is being controlled by Autoflight Logic Autopilot. It was a gusty day, forecast between 15 & 25 kts (this is outside DJI's recommended limits) but the Inspire's flight was otherwise perfectly normal. The video became wobbly in mid flt. I had already completed 2 large circuits immediately before and those videos are fine. Midway through the 3rd circuit the video became wobbly and continued this way for another minute (to the end of the flt). I didn't notice this until I downloaded the video and so didn't take anymore video that day. Here's a small extract just before and just as the wave starts.
I have reviewed the log, there is nothing I can see thats unusual. No dropped data and the RC is good throughout. I've graphed the gimbal and drone pitch and roll angles and I dont see any wobble. I have checked the Inspire frame and everything is solid, no loose rods and brackets. The motors seem to be perfect (no wobble). It does seem to me to be in the video itself, ie in the camera and not caused by the drone.
