I'm running the Kanai 2 buggy and just picked up an MRX on-road......(both off Ebay and both great deals in great shape) what # of teeth are ya'll running on the pinion for on-road 21 engines?.
I would imagine on-road runs a 16-18 tooth pinion for higher top end versus a 13-15 teeth pinion for bottom end grunt on the dirt.
Is this close? I'd like to swap .21 motors between the on-road and buggy and swap pinion gears, till I determine the best gear/motor combo.
Looks like Ofna clutch/flywheels and pinion gear bells are interchangeable and work with both chassis.
