TAMIYA's REV-TUNED MOTOR is a high-performance motor for the Dangan Racer series. It is Tamiya's Mini 4WD Grade Up Parts "Rev-Tuned Motor (ITEM 15133)". It has been stored at home for a long time. I think it's been about 10 years. Unused and unopened, but the package is bent. - Brand: TAMIYA - Model: REV-TUNED MOTOR - Item No.: 15133-300 Grade Up Parts Series Rev-Tuned Motor Thank you for viewing.
