we really didn't cook our motors last year so much as having the back deform and bad stuff came out of the slots in the back. I remember there being lots of plastic but i could be wrong...I just remember vividly replacing the motors then havign to disassemblle and reaseemble the gearbox because we did something wrong and the gearbox began binding...heat might have added to that too...but then...but regarding the overheating factor, we were running one of our motors in reverse...on a somewhat inneficient 4 wheel drive powered only by 2 drill motors...and I think it's possible that one of the motors vents was blocked so...not the brightest way to build a drive train
