Official Answer Mike Martus:

On the VEX robot you must only use VEX servos.

On the large Bot you may use other brands including VEX but please be prepared to show documentation that the servo has the rotational torque equal to the RS-232 that is the standard servo we supply in the kit. This servo is available many places including local hobby shops. OCCRA has a limited number of replacements available. Have your adult team leader contact Mr. McIntyre if you need a replacement.
