Hello Everyone,
I get the whole gear ratio thing, but here is where im confused, I have a XXX-Tmf2, i'm running the Kinetic system with a ballistic 13.5, and a thunder power 7.4v 65c 5300mah battery, a 2.4 radio and a JR 9100s steering servo, my trans ratio is 2.43 my spur is 86t and acording to the novak site I should be at a 8.5 ratio, give or take, that would mean I need to run a 25t pinion.?
I run on a short course with one triple jump and a single jump, won't that be to big of a pinion for a short course??? any sugestions on what pinion I should run, or change the spur, please let me know if the 25t is what I should run, im tring to get it all dialed inso I can be competitive.
Thanks for all your help,

How big is your track? Flowing big track? Small tight technical?

It is tight and technical, with one straightaway

If you have an MF2 with the grey trans case your trans ratio is 2.56.

2.43 is the ratio of the black case trans

I run 22/88 with my 13.5 on our small tight track with the losi SCT

Ok, good to know, thanks, I have the grey Trans 86 divided by 26 x 2.56 = 26
thats bigger yet ???

that would be a 10.24 ratio what is your internal trans ratio ?

2.43. Thats a 9.72 ratio.

For my truck would be a 10.24 and novak says run a 8.5, so running higher would be ok and lower would make me overheat, is that right?
Thanks

I would try it high and then start raisingt he pinion or lowering the spur
