Need help / In need of extreme speed control

[BIG-J]

I'm looking to purchase the E-MAXX. I've been R/C'ing for quite some time and enjoy creating insane modified models. However, I have been out of the R/C scene for about 3 years due to lack of local racing.

Anyhow, I want to buy an E-MAXX, throw some cobolts in it and 20+ cells.

Any ideas as to which speed control could handle such a load?

Thanks for the time!
