In a two minute match you shouldn't be getting them THAT hot. If you do, you've got a serious
mechanical problem. The Muffin-Fan is pretty much useless.

We usually just let them get hot (not toooooo hot) and then cool them in between matches as
needed. Dr. Joe talked about cool in a can, that stuff works pretty well. Another trick we found
was to just hold a shop-vac on he motor. It should take about 3 minutes for em to almost fully cool
down.

You might consider putting another reduction on the outside of your gearbox. This would reduce
motorstrain and keep em from heatin up.

If your still blowing motors, the only thing i can suggest is to take it easy on the motors, your
transmission might be putting too much strain on em. Maybe limit the amount of voltage the
motors get? Dr. Joe is the drill-motor-man, what's the best way to reduce strain on a motor,
without redesigning the drive system?
