Hi guys!
Something about this thread smacks of familiarity. It also seems maybe the simplest explanation has already been stated but has not grabbed but Ty’s interest.
“Interesting you say you’ve seen it without the props on.”
My E50 is back with Vertigo for this exact reason. Out of the case, first power up, the E50 was buzzing. Power off, back on, plus gimbal calibration seemed to clear the buzzing. I also determined the buzzing was actually the gimbal visibly vibrating before the calibration was performed, in case anyone was wondering.
When finally flying, I had some clear video and didn’t think about it again. That is, until the next day when I notice the video, during flight, was jittery on the ST16s. Sure enough, it was in the recorded video as well. Recalibration seemed to clear it once again.
However, subsequent flights also had intermittent “jittery” video. Usually when hovering it [jittering video] would come back, but sometimes also while cruising.
It wasn’t until after one flight, upon landing and motor shutdown, the video was still jittering. That’s when I could also hear the camera buzzing. Touching the camera confirmed the vibration. Moving it would temporarily halt the vibration.
As I said earlier, Vertigo has had the camera since 1/26. First words says they cannot reproduce the issue. We’ll see how the week progresses.
Bottom line in my troubleshooting mind... “jello” or jittery video is not always props, motors, or dampers. Rather, something has the gimbal fighting itself. TyPilot is confirming my suspicions. I’m just hoping it is in the camera; perhaps the effect of some loose screws inside the camera itself as a Yuneec tech support rep seemed to suggest, or some other fixable issue within the assembly. I don’t want to ship back my H520, let alone have to start considering a possible electrical feedback-type issue with the whole platform (H480 and H520).
I’ll keep ya’ll abreast of what I find out.

February 1, 2018: Just heard from Vertigo Drones - While they could not replicate the issue with my E50, they are sending a new E50 to me. Hope to see it some time next week.
Keep your fingers crossed for me!
