The copper windings. See if there's any signs of burns. You were geared for 37mph and if it was me I would've started at 30/72 and taken from there, but I don't know how big your track is so all I'm doing is given you a starting point to check temps after you race a full 5 minutes. Your motor might've had something else go wrong that caused it to heat up like you said.
