motor fan and esc fan
 

where do i get them and what size ?
can i go to radio shack ?.......whats the voltage ?
how do i mount ?

5 volts,I think 25mm fans. high rpm. Get a switch for the fans so you can run them in the pits. Easiest fan setup is the Reedy clip-on heatsink fan combo.

stay away from radio shack. Try an electronics supplier.
Here is a link to a fan I have used

I use Novak fans mounted on a piece of scrap lexan in my cars
Novak Fan 2 pack or Digikey

I haven't used any other 25mm fan other than the Reedy fan, but these things push A LOT of air. Much more than most 40mm fans I've seen. Highly recommended. :nod:

Here is the cheapest place I found to get the small fans - like the ones AE uses - http://www.hobbyshopper.com/extras.html

Look at ESC fans...Cheap price, quick shipping...I order mine and had them in 2 days...

Cheap fans and multiple sizes all at 5volt, most under $4
