Cherry: Not rubbed wrong at all! Nothing melted, the rotor just "came through"...My buddy is taking it apart this week to do an autopsy. He has been VERY careful not to overheat this thing that's why we've both been hitting the brushless motors with the temp gun immediately after a 5 minute heat and adjusting as needed. This one blew in a Corally RDX with a very smooth drive train so we can rule out binding. Every time he contacts Associated with questions he either gets an "I don't have an answer for that" or it takes forever for someone to get back to him. I have run teh GTB system for 2 race nights now, it has smoked evrything else on the track power wise, and I have not had to touch it once. Get's frustrating to my friend who spent a ton on his car and the brushless setup only to have to keep replacing motors.
