Have a new Mavic Platinum ( having had Phantoms/Inspire,etc previously) with only a handful of short test flights. Noticed that the gimbal in it's initial start up would hit mavic body at top when set up. I did both an IMU and gimbal calibration to attempt to fix the "bump" to Mavic body during gimbal start up. During the gimbal calibration between 62-68% completion the gimbal goes up and then abruptly jerks down (not smooth as the rest of the calibration). Is this normal for the Mavic Platinum? Or do I have some sort of hardware problem? Thanks.
