Motor Fans

[Will's]

Every week I see people as soon as they get off the track putting fans on their motors. How much difference does this make given that is 20mins between heats anyway?

With a fan you can bring the motor and esc temp down to ambient or slightly less in about 10-12 minutes.
Without, dependant on the layout/chassis and how hot it was when you pulled the shell off, and what the weather is like, you might still be looking at 40 or 50 degrees. (I'm actually geeky enough to have checked this)

A fan was the difference between my truck finishing and being pushed over the line

Off to the shop tomorrow for a fan!

If you have PSU or a "spare" output on your charger (i think most do now?) you can just use a PC cooling fan.
I got an 80mm fan, a couple of guards (to stop bits of wiring getting shredded!), and a handful of nuts and bolts and put mine together for about 5 quid.
Just plugs into an output on my PSU.

+1 get a PC fan, they are usually really cheap quite and several have grills. You or a mate might have one from an old pc lying around.
