I have at least 25-30mins of play (as always), I noticed the motor got hot and the battery ESC are also hot....but I want to push it so 5 mins stop and she's off doing hill climbs and bashing stuff then it stopped, at first i thought LVC kick-in cause i set it a bit high (correct me but im not sure if its LVC or thermal) after a few minutes or so i heard the TX sync of MM and she's off again. Finally after another 5 mins she stop. I opened the body and noticed that MM is still turned on but motor is way too hot as well as battery. If i hit the throttle you just see the green/red LED on MM for forward/reverse but its not moving. I thought the motor is a goner so i packed and went home. After I got him I decided to test it again and the dmn motor worked..still got its punch so now..im not sure if it was the motor or the ESC. But I guess this motor is tougher than I thought.

Maybe others could shed light on what happened but I think motor still working fine.
My 2 XL motors works too and the ESC that I'm testing actually lets me know if the motor is bad. It must have something to do with the BEMF signal it's receiving and the controller will stall. You probably demagnetized the rotors a bit and it will basically make everything run hot. I had issues like that before and found out that the ESC will actually send more current to try and move the demagnetized rotor and things will get over worked.
