Default 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!

Heatsink would work, maybe chill the heatsink on ice before you use it, if you need to chill it fast.

A regular fan will cool the car, ESC, and motor rather quickly. I set my 1/8 scale near a fan someone brought to the track to cool them self off in the pits and the motor cooled 5x faster than normal.

Well I have never raced before. Are heats usually one after the other, or does each class go through their first heats, then after that everyone does their second?

Yeah.. there's plenty of time between heats. The track RD will rotate through all classes so you'll have plenty of time. The only time you'll have to race back to back is if you bump from main to main, in that case you won't have time to cool anything.

Ah that would suck, although I'm sure the titan could handle it if I lower my pinion, which I should, right? On a track with jumps and many turns, wouldn't you want the extra acceleration versus topspeed? Also, can I have a link to the heatsink that was discussed earlier?

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.

Do I have to take the motor out, or can I leave it in when I use this?

get a can of computer dusting spray, flip it upside down and spray it on the motor. thats as fast as you will cool it.

No, this slips on over the end of the can, no need to take motor out.

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.
