Pysguy, you want more power run metal wheels..and the rest , you need run tamiya power-dmd and tamiya gear box for max speed and torque. Otherwise, the new mato heavy duty gear box(similar to asiantam= same) would just be fine. But from my experience, tamiya gear stock gear box is more than enough...


Please enjoy..
