Hi all,

  

I have some issue with my phantom 3 pro (all worked ok for 40+ flight before)

But I seem that the gimball stabilization is perturbated

  

I have recalibrated IMU and gimbal but not sure if there is a specific additional gimbal calibration to do

I always fly in follow mode so normally I expect the horizon to kept straight which is not the case here

  

When I fly straight forward the drone (kept horizontally), when I start the gimball tilt on the right (like overcompensating)

  

And I stop, the camera tilt on the left (again not needed) and I do not have stabilized image as before

  

See video extract here : https://www.dropbox.com/s/4zu4qn7x1k2hn08/test.mp4?dl=0

Is there a specific calibration I could do ? Thanks for your help in advance

have a check and see if one of the white rubber dampeners that smooth vibration has come out of its location. happened me before but not after a crash. thats all i can add to this

Unfortunately your clip is too short to get a good idea of the problem. You should be able to do the same thing while holding the drone on the ground and tilting it. Perhaps you could shoot a clip of that being done.

Have you tried to recalibrate the IMU and gimbal, may as well do the compass too. Haha

Yes there is a gimbal calibration, from the Gimbal Settings menu you can calibrate the gimbal.
If it still does the same thing than something internally may have need damaged in the crash and you may want to send it in for repair.

Excellent idea as indeed more accurate. Thanks for the idea.
I just did a quick video where I move the drone slowly on the floor (front or back) and we can see well that the gimbal is not keeping horizontal and do slowly (very slowly) come back to horizontal

I did a recalibration before with no success. Guess this is no other other way to correct and has to go through servicing ?

Yes I did both + compass (for flight) but no change

Yes, I'm sorry. Looks like it would need to come in for repair.
