Hello,

I am trying to frly the drone in -4 degrees celsius, but the gimbas shakes A LOT.

I tried leaving the drone outside for 15 minutes, and then recalibrate the IMU, this maybe helped a tiny bit, but the gimbal still shakes a lot, expecially when braking and when descending.

Is this expected, or could this indicate a bad gimbal? I hade some problems with jello before, when it was warm outside, but the issues seem to be solved with ND filters and applying the 180 degree shutter rule.

The problem i am having right now is deffinitely not jewllo thoug. It almost seems like the gimbal goes crazy for brief moments while trying to compensate for movement of the drone.

Hi,

the operating temperature range is -10° to 40°... Anyway, could it be some condensed moisture on the gimbal arms? Maybe it doesn't move and stabilize well at that low temperature...

It's low temperature here now too, and I'm going to fly this weekend, so I'm curious how it will handle it....

Please do update this thread with your findings after your flight!

Hello, djiuser_Fr3KlXzkpbRW. Thank you for reaching out and we apologize for the inconvenience. Please try the following operation:

1. We recommend using a filter or narrow the lens aperture to increase the exposure time, or lower the degree of moving the control stick to obtain a better view effect.
2. Check whether the gimbal has fallen off from the gimbal buckle. Please perform gimbal and IMU calibration in the DJI Fly app, and check whether there is any error.
3. Please check whether there is any error with the original footage in the microSD card. If not, this issue is caused by poor image transmission signals, such as:
a. Insufficient handling capacity in the mobile device;
b. Strong signal interference.
4. Please try to fly on another flight environment. If the issue persists, you can provide us with a  video for further checking.

Thank you for your kind understanding and valued support.

Thank you for the response.
You suggestions, however, are very generic, and do not help my case.

As i mentioned before, from the flight footage it is obvious that the gimbal is being  improperly stabilized.
I will try to provide video footage.

As temperatures decrease the material comprising the gimbal dampener is likely to lose flexibility.  This may render the camera more susceptible to vibration.  Cold temperatures definitely make the structural plastic more brittle.  The other day while flying low in a park I clipped a tiny tree branch.  It was moving slowly & the Mini 3 fell perhaps 3-4'.  Front left arm snapped off cleanly right at the joint.  The pivot is still solid.  It was about 20° Fahrenheit.  Finally I get to use DJI Care!

This is, of course, true.

But, look at the 0:14 mark in my video, the gimbal turns to the right sharply. I was looking at the drone when it did that, and it was stable, the body of the drone did not tilt to any side, nor did it fight any wind. It seems like the gimbal just decided to sharply turn right for no real reason.

Did the gimbal shake in a similar flight in warm weather prior to the cold weather?

No, first time i noticed this is in this weather. Before that i flew in around +12C degree weather with no problems. I do have jello with this gimbal, but only if the shutter falls below about 1/200, so i solved this with ND filters.
However, this recent shaking in the cold led me to believe, that maybe something is wrong with the gimbal, which reproduces much more visibly in the cold.

I frequently fly in as cold or colder conditions -17f so far and have noticed that really cold air tends to magnify little things (or at least appears to). You appear to be flying in sport mode when this occurs. I only say that judging by the movement speed, if so I'd kick it down a notch or two (normal/cine) and that should help.

Prop icing can cause instability thus leading to gimbal shake, much the same as a damaged or out of balance prop.

FYI icing can occur between -10C to 4C with a high humidity. Anything below -10C then the air is normally too dry.

Having read a reply of yours referencing 0:14s is that the shaking you're on about? if so then this is normal behaviour when the gimbal is overloaded, sports mode is a contributing factor, that and coupled with wind, and or when using a filter or sudden movements as shown in your video.

The 0:14 in the video was in normal mode. And let me put it this way:
In the same conditions, but in about 15 degree warmer weather, the gimbal would be dead stable when manouvering the same way i did in the video.

Hello, djiuser_Fr3KlXzkpbRW. 1. Narrow the lens aperture to increase the exposure time.

Did your brain take the day off?  There is NO adjustable aperture!

My 3rd paragraph is most likely the issue, FWIW, its not the same conditions, its colder. You're flying in -4C, 15C warmer is a big difference.

Heres a bit more on my take, I think you need to send it into DJI, i have a sneaking suspicion it may have taken a tumble at some point, you shouldn't need to use an ND to reduce any Jello effect cause you shouldn't have Jello at all, hence why i think it took a tumble, perhaps a prop is OOB, this, in turn, has made you resort to ND to reduce the jello effect, this, in turn, has led to the wobble, perhaps the extra weight on the gimbal, it happens throughout your posted video, it ranges from hardly noticeable to really bad, the colder air could be putting extra strain on things thus your issue.

Also, if 0:14 is the main issue then you need to edit your 1st post from shake to say "jumps" or @wobble@ as its not shaking and more a jump, and it will be better understood for other members so as to help with better answers.

I did not watch the video before my previous post.  Your gimbal is geeking out.  My Mini 2 has exhibited rare but similar gimbal glitches, usually when flying sideways in windy conditions.  Is this a rare issue, or is it happening frequently or always?  Try calibrating the IMU, Compass, & Gimbal.  If the issue persists I would send the bird to DJI for service.
