haha yup, it's geared for 90 mph with the 15T pinion, but i have a 10T as well wich I didnt calculate yet, but I think ill have enough torque with those motors anyways. The Gears are 1.5 mod too. It has a 400mm wheelbase and 300mm track width, so a xo-1 body will fit great, but id rather use the corvette body they make.
I could also use GRP wheels with these square drivers.
But I will not make an on road setup yet, I will be using an sc8/ apache sc body and I will have to extend it by 20mm. I could also remove the front pulley and have RWD only.
