[MrForbes]

it's in the rules...somewhere...oh here...

<R53> So that the maximum power level of every ROBOT is the same, motors and servos used on the ROBOT shall not be modified in any way, except as follows:
A. The mounting brackets and/or output shaft/interface of the motors may be modified to facilitate the physical connection of the motor to the ROBOT and actuated part.
B. The gearboxes for the Fisher-Price and Globe motors are not considered “integral” and may be separated from the motors.

is what you want in here?
