Yesterday, I had been flying my Phantom 4 pro drone in multiple locations.  On the last stop, I started it up and the gimble made the sound in the video and behaved the way you see in the video.  This is a refurbed unit that I got from DJI last year when I had my original drone repaired.   This refurbed drone has not been crashed.   There are no error messages.

I refreshed the firmware.   I calibrated the imu and the gimble.   It still does the same thing.  The gimble is unresponsive to the controller.

This is why I hated the idea of getting a refurbished drone back.

Can someone from DJI respond to this post?   I used the chat function and they were supposed to have someone call me back the day before yesterday.

Yeah agree, one of the reasons why I prefer not to have an R unit. Somebody's issue that become yours. Sounds like DJI needs to make this right for you. Good luck !

In case anyone experiences the same thing.

Did you have to pay?

2 hrs to replace those motors and IMU is quite a while, im assuming that the imu is in the behind that gimbal cover? I switched over my  yaw motor and it didnt take half that time and i didnt know what i was doing, perhaps they had to do some calibrating that took it over the 1hr

Yeah, I  had to pay.   They replaced the landing gear too.   The covers on landing legs the refurbed unit I got kept getting loose soon after I got it.
