I have an ECX Amp MT. Im doing a brushless system on it (Copper head 10 ESC w/ 3800kv motor from Castle Creations). Does anyone know if theres some sort of transmission case upgrade? Not a fan of the screws digging into the plastic case for the motor. Ill also be upgrading the gear set to the metal gears as well as a metal spur gear. I have looked online but unable to find anything. The closest i have found is the Pro line trans for the slash and stampede but dont know if it will fit. Any help is very appreciated. Thank you!
