MMM Explodes into FLAMES!

20/54 with those massive and heavy tires is probably part of it. You said the motor never got too hot though, so that makes me doubt the gearing a bit (if the motor is getting hot it's pulling enough amperage that the ESC is most likely getting hot as well.)

Looks to me like a FET couldn't handle it and it blew, Castle will definitely take care of you on this. I really hope they can get different FETs or maybe find a distributor that has better QC, it seems that they aren't quite up to snuff. Sure the failure rate is low but still too many are going IMO.
