E-maxx motor?

I dont know, some people are having some minor problems running big block motor with the MambaMax ( its originally made for 1/10 scale cars), but if you can push the envelop a bit, go for a high quality motor, which is going to make the controller work a bit easier. I say check out the Lehner 1940/8 or the Neu motors. These are the real deal.
