I just received today the replaced unit (refurbished) of my Mavic of my repair case
Apparently everything works correctly. The horizon of the camera is centered in Roll 0.0, but every time that I turn on the Mavic, after 10 seconds of runing, the horizon tilts to the left, and the gimbal returns to the correct position again in 30 seconds. I have calibrated IMU, compass, and gimbal. I have also reinstalled the firmware again but the gimbal continues to do this.
Problem tested in firmware 1.03.0800 and the last version 1.03.0900
