Thinking about a speed run car

[Metallover]

I got the tc3 yesterday. came all thrown in a box with no packaging to speak of. The foam front bumper wasn't held down so I fixed that. I don't like how the gear mesh is set either... It came with drift tires on it. Body is pretty nice- good flexible strong lexan.













I like how my 4s lipo will fit in there after some dremeling, so I think I'll go with the 4s system. Can anyone tell me what it will take to switch to a 32p spur gear?
