Just had a problem that I have never had before, I had flown 3 batteries worth of flying and on the 4th battery I had flown to a height of 100 mtrs and was doing a 2 second timed recording on a new round about near were I live, all of a sudden while looking at the screen it appeared the p4p was tumbling out the sky, my heart sank, then a gimbal overload warning came up on screen, I checked other settings and it appeared the drone was still stationary with the camera jerking about all over the place, I spun the bird around and headed back to home, the camera now just showing the leg of the p4p, I got it back ok which was a big relief.
Anyone else had this problem happen ? I shut the drone down and restarted and it seemed ok, bit of a worry

Seems not only You have similar problem:

It would be nice to let DJI know about this.

Did you notice this happening when yawing quickly, or was this while flying forward or while stationary? You haven't flown it since the incident, correct?

It happened to me when flying forward with low speed. Wind was around 2-3m/s and YES I have flown later after reboot of aircraft with no issues.

I was stationary doing a timed shot sequence, I noticed a low plane flying nearby so I decided to lower the drone, And was a lot lower than 120 mtrs  and just precautionary, all I done was descend and then noticed  on the screen that the camera was jumping all over the place, I decided to do an IMU and gimbal calibration today and flew 5 batteries worth of flying with no problems, just hope it does not happen again

Very odd it should happen, I thought the drone was falling out the sky !!!!!

Exactly I was thinking same way! I almost got heart attack ;)

Mine has been ok since, odd and hope it does not come back lol

I had it also happen once. It was on a relatively cold morning so put it down to condensation or something. No problems since. Scared the life out of me though.

Lol sure scared the life out of me too Dav, was warm and dry when it happened to me, I was fly quite a way up and away from me and had lost sight of it when I looked at the screen and it just looked like it was tumbling out the sky, below was a pretty wide river !!!!!
