It was the wire of the motor to esc, pinched across a sharp edge of the motor can. Motor got hot enough to melt the wires. I suppose somehow the signal for "reverse" received some voltage. That was the only damage I saw, now seems to work fine. But I did change the esc in the truck to the ISDT90.
very cool truck, looks fantastic 👌 nice crawling, what happened at the end? esc or motor?
Pretty sure it was esc. Just started rolling backward, then nothing. Going to dry it, take it apart, and inspect.
