Briang"s motor calculator should tell you good motor possibilities.

MM and a fiegao is a popular way to go I've noticed.
I've been loving my MM / Ammo 36-50-2300 / 3S combo, but I run a small track so I wanted to be able to gear from 25-45mph. You would propably want a few more motor rpm's so I'd go more in the 3300-3900KV range. But defer to brians calculator and the guy's who run CRT.5's...
