from this i hope to buy the correct range of pinions and run it over winter
I buy my foams pre trued as well if that makes any difference...
This is dependent on a few things , I was in the same position as you a couple of weeks ago ,
You need to think about track size , motor and speedo combo , and then finally tyre size
in 1/12th racing the guys talk in rollout , not FDR , this is how far the car rolls for 1 turn of the pinion ,
I am too lazy for this and use Gearchart on my Iphone to work it out LOL
good luck and i hope you enjoy 1/12th racing as much as me
