Cooling motor off
Just curious, I want to race stock slash at my lhs, and was curious as to what my options are in regards to cooling my motor off between heats. I know I can just let the air cool it, but are there any faster means? I was thinking of maybe a heatsink to apply between heats, or, well, no idea. Thanks in advance guys!

I just bring one of those circular fans that's very squat, where you can angle it up and down. I point the fan upwards and just set my car upside down on it (watch your antenna tubes!).
Or, you can just have it point towards you and just stick your slash sideways, on two wheels, and let it blow your ESC and Motor.

You can always dip it in ice water 
Seriously though....
The motor shouldnt be getting that hot, to be of a concern, during a normal timed run or amain.
If it is getting hot to the point of concern, you should probally lower the pinion by a tooth or two, to make sure it doesnt overheat.
Your least expensive route would be to bring a small electric cooling fan, like you find at walmart, and put the truck in front of it between uses.

oh...
Also if you cool it off too quickly, as with a motor or electronics spray, the transition from hot to cold quickly, can cause the magnets and or brushes to crack and break.
