My Mavic is experiencing the jello / wobbly video (that I've since discovered is not that uncommon). Here's a video ... (skip to 2.39 for quick example)



It started off fine (also the flight I did before this was a bit better), but then the 'jello/wobbly' gets worse and worse. starts off at 0.59, comically bad at 2.39, and continues in the shelter of my back garden at 5.38

Wind was about 14-20mph and I did get some warnings about high wind, BUT this doesn't explain it happening in my back garden on the same flight..

It was doing this on the first day and I was getting 'abnormal gimbal vibration' warnings, I then discovered than the gimbal wasn't seated under all its tabs, which I fixed, its perfect now, but the above video is since then.

This is the very latest firmware (v01.03.0500), I have refreshed several times, several IMU calibrations, several auto gimbal calibrations, several camera setting resets.

Temperature was 9c, not sure why that matters.

No ND filters yet, don't see why I wouldn't be able to get usable video without them

Props seem fine, I have switched them around with no big difference.

Should I be sending this back to the shop for an exchange? Or to DJI to fix (this seems like a drawn out process and where will it go? I'm inUk)

If you did COLD IMU on a 100% perfect level surface that I would return it and get and exchange for a new one instead of sending it ofr repair!

thanks for the advice! Whats a 'cold' IMU? Ive done a couple of IMU, not 100% sure what they are but they seemed straight forward. I did it on a very hard, but level carpet, not sure if this was good enough or not

You did not use ND filters to lower your shutter speed, this could be one of the reasons that you experiance the effect I see in your video.

Putting the AC outside without the battery for 1/2 hour in cold temperature 10C or less and then quickly do an IMU calib on a 100% level surface

Hi jimelliott, since you have tried all basic troubleshooting, I'd suggest you to send it in for further diagnosis.
