Before I contact DJI Support and possible send it in, I thought I'd check here one more time to see if anybody had a solution.
So ever since I got my Mini 2 almost 2 years ago, it has, on occasion, started to turn while flying. It looks as if it is flying diagonally. Usually, I'm able to just do all the calibrations and it will work fine for a few months and then I have to calibrate again. Lately however, it seems that calibrations have lost their effect.

I have 2 sample videos of this happening. In the first video, you can see that I have the crosshairs aimed on a bush. I was careful to not go full throttle right off the line as to rule out the spinning of the propellers as the cause. Almost immediately, you can see that the crosshairs move to the right. By the time the drone gets to the bush, it is at least 18 to 20 feet to the right of it.

First video: https://despain.me/Screen_Recording_20230104_154813.mp4

In the second video, I try the same thing but at a greater distance. I train the crosshairs on the white object and then start to move the drone forward. Same as before, the crosshairs immediately begin to move to the right. After re-aiming, I go forward again with the same results.

Second video: https://despain.me/Screen_Recording_20230104_155538.mp4

PhantomHelp Log: https://www.phantomhelp.com/LogViewer/4DVZDZ42BIQ6BPOTXEDL
The first video starts at 4m30s and ends at 4m48s.
The second video starts at 10m00s and ends at 11m55s.

Things I have tried:
  • Compass Calibration
  • IMU Calibration
  • Gimbal Calibration
  • RC Calibration
  • New 3rd party propellers
  • New DJI propellers
  • Removed vinyl accent wrap


I've been trying to avoid having to send the little guy in for repairs but as it gets closer to the expiration day of my Care Refresh plan, i'm wondering if I should just bite the bullet and submit a repair request.

Has anybody here experienced this as well?
Does anybody know of a more permanent solution?
Should I just submit a repair request with Care Refresh?

Your drone is probably flying perfectly straight but the gimbal is slightly offset and not pointing directly ahead.
The data shows a fairly consistent difference between the drone's heading and the gimbal yaw angle of approx 18°.

Ok, do I just fix that by doing a manual gimbal calibration? Or is this an indicator of a bigger issue with the gimbal?

I did notice that the calibration screen crosshairs and the camera crosshairs don't line up at all. Is that normal?

Is this something that I can use DJI Care Express for?

Hi,

Had a look at your flightlog, see my chart of your data.

Heading *  and move line ** on top of each other ; your drone flew perfectly straight line.

* compass data
** GPS position data

Cam is offset drone heading, see chart.

cheers

I had the same problem on my Mini 2, and now I have it on my Mini 3 Pro. If I fly straight it would start turning left for a while. When I let go of the controls drone would stop and slowly correct itself. No calibration fixes the problem. It looks like gimbal starts to turn for no apparent reason, even though there is no wind.

After I had already made a case and sent mine in, I found this:

No worries.

I made a request and received my replacement drone yesterday. Test flights came back with good results.
