Roll out

[Paulnuneaton]

Hi guys need to pick your brains there must be some clever guy out there that can answer the question im about to ask.

Right 13.5 brushless 1s lipo whats the best roll out for this car please

at the moment runing 18 pinion 46 spur

can any body give me some roll out figures or how you work it out do you need the lower or higher roll out HELP PLEASE

rollout is calculated using the following:

pinion x tire diameter x 3.1416 / spur = rollout

however if someone gives you a target and you're not sure which pinion you need, the following will help

rollout x spur/ tire diameter/3.1416=pinion

Can't help with the actual gearing you need though, sorry
