Logictech 2100 gyro factory calibration

[mnentwig]

Hello,

sometimes the 2100 gyro tends to drift. Usually it's a vibration problem (i.e. fix the heli first, before doing anything else).
However, if the servo creeps on the bench, with the motor off, here are instructions to perform factory calibration.
This is otherwise not documented:
