Look for threads on 1/12th scale ESC's as they are the same power train.
I have run an LRP SXX V2 Stock Spec without needing anything and it was great. I am running an AE Black Diamond now which needs a receiver pack. The receiver pack is a bit of a hassle (2 things to charge) but since the ESC does not come with a switch and my receiver pack does, it serves as my power switch which is handy.
