Hi Guys i am fairly new to on roads electric and i have herd all this talk about roll out and internal ratio setups. This completely baffles me. I have a Corally RDX PHI with a spur 68 and a pinion 40. I also have a 17.5 Novak motor.

When i spoke to some guys at the track i go to they said that ratio is alright but i have been looking at all these different charts and still have no idea whats going on really.

I wouldnt mind putting in a bigger spur gear cause compared to alot of the other guys they are running one which are a lot bigger.

Any help would be greatly appreciated

cheers
JAJ
