Re: FisherPrice Problems
If you blast it with cold spray, don't do it where the brushes are (near the cutouts in the back of the motor). You could crack them.

Anyway, here is the solution http://team696.org/images/fpcooling.jpg

And buy that exact heat sink here http://www2.towerhobbies.com/cgi-bin...?&I=LXTG84&P=7
But there is a cheaper one here that looks like it will actually fit better http://www2.towerhobbies.com/cgi-bin...?&I=LXJCZ9&P=7

I recommend these to anyone using a Fisher Price motor in any application (other than in a Dewalt transmission, it will not fit).

We used these every year since 2003 and have not had a drill or Fisher Price motor get too hot since.
