CRT .5 with extended chassis is a must. I'm running a Velenion (3500) with a MM Controller and a 2S-5000 and it runs great (not overpowered). I have run a 3S-5000 and its insanely fast. Stock Spur and mod1 18T pinion.

I'm looking for an easily removable wheelie bar for street use. Anyone found one? (pics)
