those trinity motors will really wake that E-Maxx up, but you could also buy another ESC fairly cheap and then run 17 turn motors, still have a pretty good run time, and be pretty quick. If it was mine, I would go strictly brushless and LiPo. No telling what the runtime would be with a Novak HV 4.5 brushless setup and two maxamps.com 12,000 mah 2S LiPo batteries!
