What size pinion gear are you using? You are currently set up for about 77mph (3.5vC, 2200kV, 4.5" tire). However you will still be able to spin your tires without fail. Just be wary of the jack-rabbit starts (with that gearing) or your MMM will say "Screw this!".
 Get it rolling a bit before you punch it.

have not run it yet,
tires are 5" tall hard rubber not sure on what spur/pinion that will work best but going to try a 49 spur and a 14p=11.5:1 . maybe go 17pin =9.5:1 also have a 45 spur I ran 15:1 ratio with 3s on 1/8 wheels 4 3/8" tall street tires and it was awesome
