You could get a Novak Havoc Pro or a Novak GTB (both list a 3.5T limit, but I've never seen a motor less than that). The main difference seems to be the GTB has more profiles to choose from. Couple one of those with a Novak Ballistic motor and you'd have a quick setup.

If you want to delve into the world of tunable ESC's you could pick up a Tekin RS or RS pro (5.5T limit vs. no limit). These will allow you to setup adjustable timing to get even more speed out of your rig. I would still go with the Ballistic motor even if you get the Tekin ESC.
