A couple of times recently my gimbal has stopped horizontal satbilisation and instead rocks from left to right as the Phantom 4 is moved left to right.   I noticed it when panning.  The problem goes away when powering off then on the Phantom, but this has happened a couple of times now.  I have the latest firmware and app version.  Anyone else had this?

Hello Carlton, may I know it was working fine before? would you please try to cool it down and do IMU calibration in a very level surface, please do not move it during calibrating period. Then please calibrate gimbal manually.

Yes it was working before and it seems OK now.  It has happened twice on different dates.  How do you do an IMU calibration.  I can't find that in the App menu?

With all powered up and connected it should be in the 'aircraft status' menu OR 'Main Controller Settings/Advanced Settings/Sensors' there is a calibrate IMU option.

Here is the screenshot for your reference.

IMU calibration was in Main Controller Settings, Advanced Settings, Sensors, Calibrate IMU.  Have done this.  Powering on the Phantom and the Gimbal appears to be fine.  Will test this in the field and report back.
