Which Brushless motors ?

Guile,

What is your primary requirement? Are you going to race your e-maxx or bash? You want high speed or low end torque?

You noted that you're running g-maxx stuff, I presume that w/ 14 cells you'll be a bit lighter (weight wise) than a stock e-maxx.

Knowing this will help you determine the best motor/speed control combination for your application.
