Are these DC brush motors? They may not be, as Compumotor
makes just about everything BUT, I think. Do you actually have
these motors in hand? How many wires do they have? Are
brush holder visible on the side?

If you can identify 2 heavy wires for the motor power, you can
connect to a D cell and see if the motor turns slowly. If it has
3 or more wires coming out, it may not be a DC brush motor,
which is the only type the gecko servo drives support.
