Nitro 4Tec
Hey. my brother have one, but he can't to reach me with my TC3, U need to think about the EZ start, lol is convenient, but not useful if U want to arise the speed besides, it weights too much.
Just try changing the engine with a Novarrosi, RB or Picco, I really recommend U the Mugen Novarrosi MT-12, it have a 1.15 HP and 36,500 RPM's
