mod 1 pinion . bore ????

Gearing will depend on the kv rating of the motor, now we know the voltages and tyre diameters. Not sure what spurs that thing uses, but Im sure something from a kyosho or similar 1/8 scale vehicle will fit. The ratio is listed for diffs, ony says 1/8 scale, but I'd guess 43/13 probably.

hey neil the motor kv rating is 3900kv... i will check the spur today hopefully that will be enough imformation to reccomend a pinion of correct tooth count ,
