We never change the motors of our machine once they are running just as a matter of course.

One year we really missed the ratio and we underestimated the amount of pushing we would have to do (the puck year!). That year, we used the burnt insulation test.

If the motor smelled like that pukey burnt laquer smell, we changed them out. Typically that would be after a regional, we never had any trouble in practice no matter how long we practiced.

By the way, for those who are driving with the Fisher Price Motors, we used them that year as well. You will be interested to know that these motors come with a built in "I have been over heated" indicator... ...The fans melt off the armature shaft! Really. All that is left is a ring of fan blades that do not spin when the motor spins.

Low temps to us all!

P.S. I have never seen the fans melt off the drill motors by the way, no matter how badly we toasted the windings. JJ
