To stop any confusion...
a LOW gearing (= high number) eg 10:1
a HIGH gearing (= low number) eg 6:1
A RS540 silvercan only revs to about 20,000rpm, so if you want higher top speed you need to gear Up. For a higher ratio, you either use a bigger pinion, a smaller spur gear or both.
A modified motor can rev a lot higher.... up to 40,000rpm is not unheard of. However if you gear it too high and the mod motor is not able to rev fully for most of the lap, it will bog down and overheat. Heat is VERY BAD for the motor.
So in short... the silvercan will survive skyhigh gearings, but mod motors should be geared lower so that they can rev all the way.
i just bought 20T & 21T pinion, and had tried the 20T pinion, really can see the diff by comparing with the 16T pinion...
You can go up to 25t on the TB01. On a large track, the 25t is very suitable for the silvercan kit motor.
