This is the motor and encoder portion of our high-power (HP) 25D mm metal gearmotors with 48 CPR encoders. It does not include a gearbox, but the pinion gear on the output shaft works with all of our 25D mm gearmotor gearboxes, so this can be used as a replacement motor or encoder for those gearboxes. It is intended for use at 6 V, though it should operate comfortably in the 3 V to 9 V range.
Key specs at 6 V: 9800 RPM and 450 mA free-run, 2 oz-in (0.1 kg-cm) and 6 A stall.

Modifying the Wild Thumper to use motors with encoders
Customer Richard Nguyen has documented his work modifying the Wild Thumper chassis to use 25D motors with encoders in place of the chassis’s included motors.
Note: This is not an easy modification, and the chassis can be damaged if it is not done properly, so we generally recommend against it, and we can only provide very limited support for those who want to attempt it. The manufacturer did not intend for the chassis to be modified in this way, and we do not know how well such a modification will work out.
