I have superior acceleration but feel that my top end is sacrificing a little too much. So, I'm trying to maintain high acceleration while gaining top speed, which is why I'm looking for a bigger motor. Thoughts please.

I know the Jato guys pretty much agreed that for top speed/performance, the OS .18 was pretty much the best, for a stock motor. These little guys don't need the torque, they can use high RPM. Easiest performance increase is to send (or buy) a TRX 3.3 from ABMods. You'll never want anything more.
