The reports I've seen with failed (completely cracked) rotors was with running 6s on the 2350kV motors, which is 52k rpm I believe (no calculator on me). That's too high for a lower-end motor. On 4s, it's just hovering around 35k and would be mighty happy. I run my 3665-2300kV motor on 4s and it stayed cool throughout the entire run. The ESC stayed around 85F and the motor about 95F.

If you can afford it, I'd definitely get a Medusa motor over the HW EZRun motor though. Medusas are known to be well made, perform well, run cooler than Neu's, and make tons of torque. Having to equip 3 trucks though, I couldn't afford the extra $70+ per truck for the EZRun 80A + Medusa setup. If one of my HW motors fail, I'll probably pick up a Medusa then.
