I have just calibrated the IMU. Then I did the same for the Gimbal. Did not think either needed it but did it just to be on the safe side as it were. Whilst calibrating the Gimbal I noticed there were 3 configuration settings marked 1,2,3. So I have tried to look them up but all I can find at the moment are FPV - FOLLOW -APTI? not too sure if that last one is right. Mine currently has configuration 3 highlighted so I assume that is the default? So have they simply renamed the above to 1,2,3? or is there more to it than that? Can someone clarify what each does? Thanks in advance.
