Heatsink - does the motor really get that hot?
Hey guys
My friend just bought the stage 2 motor kit and gave me 2 motors, however he kept the heatsink. Does the motor really get that hot to where it affects performance? I bought a small heat sink that I can cut down to size and thermal glue to the engine, will that work?

you could probley run it with out the hs but usally when a manufactuar recommends one it is needed (well with comp parts at least) couse the manufactur is trying to save money all the time so if they give u one they usally have a damn good reason too since we all know how cheap radioshack is lol

it shouldn't really matter like Nixad said but heres a option if you have not already chopped that HS up
Get some video ram heatsinks forma computer store and use those they are thinner and only need to be trimmed lengthwise.
Just a thought

You dont really need the heat sink. I have been running my XMOD with a stage 2 motor for a while with no problems.

Yes I would use 1 b/c I was running my X-Mod for about 2 hrs and the batteries died and when I opened it up to take the batteries out I could feel the heat from the heat sink but the engine was still cool, so I guess they work well 2

If you run your car on carpet you need a heat sink. The extra drag causes the motor to run hotter.

Couldnt you just use a 3rd party one, and use some cpu glop to stick it on there?
I never noticed mine being hot with any of the S2 motors so far, even after running a set of battieries totally down.

Ok... what aboot this then...
Why not try and do a little body venting instead. You could add a scoop somewhere that feeds some air into the inside and that should help cool things a bit. Plus if done right could look nice.
Or mount a small fan?

A fan's a little impractical, and body vents don't do a whole lot (or so various threads would have me believe). I'd recommend some kind of cooling mechanism, even if it's just driving around without the body on. Even if the heat doesn't immediately kill the motor (and it seldom will), it shortens the lifespan and gradually sucks some power.

The fan thing was more of a joke than anything... since it would add weight and create more junk to stuff under the body.

I wouldn't worry about 1 too much neway, especially if ur not running it 4 long periods of time, a fan is actually an interesting idea however... hmm...jk
