Again... thanks to all of you for the really great advice... and very prompt I might add!
I will stick to the touring setup and run the car with the diff up front at first till I get used to it.
Although the class I will eventually race in runs 13.5, I bought a used 21.5 motor in order to limit myself and clean my lines, entry, exit first before trying to go fast.
What do you recommend for a pinion/spur combo? I'm running 2c 7.4 LiPo and the GTB 21.5 b/l. I don't need alot of speed at this point. Thanks.
