Esc burning up without warning
#16
Double check everything before hooking up another ESC, if the ESC was hitting thermal cutoff so regularly it could be caused by the gearing or by something binding elsewhere in the vehicle. Take the pinion off and spin the drivertrain, if it doesn't spin freely you may have blown bearing somewhere which can cause a lot of drag and excess heat.
