I don't have a EZRun motor but Hobbypartz also carries TACON motors which have been performing great thus far. Been using a 3930kv motor in a 2wd Slash for 2 months now with no probs and I drive it HARD. Probably the best bang for your buck in the RC world for 25 bucks shipped. Performance is comparable to my CM36 4600kv but easier to drive/gear.
