Right now I have a super expensive Jeti Spin 99. It's a wonderful controller and I can't speak highly enough of it. But really, if you want to save a few bucks the Castle Creations ICE 80 HV is a very good choice. I think my Spin 99 is smoother has better breaking and runs cooler but the Ice 80 isn't as bad choice.

I'm using an E-Flite Power 110 on a Focus Sport amd a Voodoo Express. Both are about the same size and weight you describe and the motor is a really good option for them. I'm using 8S packs on them and the performance is outstanding.
Dave, what esc?
