The Fisher Price motor is similar to the RS550 motor sold by Banebots. It is not the same motor, but is the same size package. They are both the same mounting configuration and 3.2mm shaft diameter as the RS540 and RS545 motors. All four motors can be installed on the 36mm and 42mm Banebot transmissions. All you need to use the fisher price is a new pinion gear from Banebots for the fisher price motor. Make sure you get the correct pinion gear for the transmission you are using. They have different ones for 3:1, 4:1 and 5:1 first stage transmissions. Also make sure you get the one for the 3.2mm shaft gear too. You have to press the old pinion off the fisher price and press the new one on the shaft the correct depth (compare the pinion spacing from the face of the motor with the spacing on the motor from the Banebot). Be careful not to bend the shaft when replacing the gear. You will also have to trim off the end of the shaft flush with the pinion. We used the Fisher Price, RS540, & RS550 with Banebot trannies on our robot last year with no problems.
