brushless 1/5 4wd conversion about to begin! couple questions.

[florianz]

go for someting like this:

http://www.thermaltake.com/product/L...5/cl-w0075.asp

it has all the needed components, and they're working the right way. and its not too big. you definately need a radiator. otherwise you're just pumping hot water around.

this thead is getting really cool...

no, he builds pumps with no moving parts. but he had a small 5 volt pump on his emaxx one time but i think it was from work though, so its not available to the public.
but that pump should work.
he also made his own radiator out of aluminum.
shoot i will just through in some pics

sorry guys no hands.... lol

That setup is cool florianz!

Seems to me there would be enough heat dissipated thru just some tubing and a tank with just a few ounces capacity however.
The radiator might be overkill as he probably won't be getting a 240 amp ESC white hot, and at $30 for the SIG pump and a few bucks for a small tank is the way to go IMO.

Ryu, you could even run a mix of water and alcohol, for example, for even better heat exchange.

you could put ice in the water to start cool,

the thermaltake set is around 100,- Euro. probably not all parts are needed and you pick just the needed parts, and you get that even cheaper in the us. I would NOT take a kind-of, self-made radiator.

as these gamer cpu's get bloody hot and that combos work well, I think this is the way to keep the esc ice cold. I think it's great that each layer of the esc has it's cooling, and that you could use that.

fluids have a higher capacity to take heat, that's why even Harley Davidson switched from air cooling to water cooling (like that more horsepower), same with Porsche. but I have to say the air cooled HD's look better...

Absolutely correct, and it should be noted that HD recruited Porsche to design that engine FOR THEM... because oddly Porsche's design team is not stuck in 1910

yep... 1910 lol... progress, what's that?!?

porsche actually designed the last two engines for HD. but porsche have some troubles now... just got eaten by Volkswagen. soon the Porsches wil be just faster VW's... but that's a bit OT

TCS Cooling has RC watercooling kits the radiator listed is smaller but they do have a larger one available if you email them.

[transtalon]

I use the watercooling setup with my Hydra 240 and Neu 1527 1D and without the working water pump and a home made radiator similar to the picture up top it made my temps to drop from 170 degrees to 98 degrees on a summer day in IL. It works on cooling but not on ESC I beleive due to a rapid rise in heat when the ESC maxes out. It will cool down better than a fan but won't save the setup when the ESC goes up in flames. I was also using a 5volt diaphragm pump. The TCS pumps is a gravity feed and when your trucks rollover it needs to be primed in order for it to work. They are a piece of crap and not worth getting for 70.00. It does work just too much lines and a little weight.

[Ryu James]

wow guys. this is awesome stuff! i really like that TCS system and the little pc cooling unit. i think i am gonna search the web for some more of those pc cooling units and see what else is available.

transtalon: so are you saying the TCS is not a very good unit to use?

i really like the thermaltake kits but the radiator/fan is huge. 120mm fan and like 150mm radiator. check out some of these sets:
http://www.xoxide.com/watcoolkit.html

anyway, here are some recent pics. here is my front swaybar installed. now the rear is next.





here are some pics of the esc without the shrinkwrap. a fan would cool it decent i think on that large top alum. plate but the water cooling would just be soo cool. i will have to see what i can do. also, here is the rx/esc box i am planning on using. it fits everything perfect. i cut holes on each end for the wires to come out and then i am gonna use an outerwears material to cover the holes to keep the inside of the box semi-sealed off and safe from elements. (even include some hand porn.)

[Ryu James]

oh, while i am thinking of it does anyone know where to find some really small pulleys that can be mounted? the reason i ask is i may need some for the rear disc brakes. in order to run the brake cables smoothly to the brake servo i want to use a small pulley system. if its not feasible i could just use another servo closer to the rear of the vehicle and then use a y-harness to run both servos but i kinda want to run them all off one servo and i have already laid things out to where it could work if i have 1-2 pulleys. plus the servo i have is 425oz so i know that it is more than enough to pull all 4 brakes.

also, on the topic of water cooling, is there a water cooled motor sleeve that fits a finned Neu 2215? i was planning on using this fan ( http://www.coolerguys.com/ec60ledalum.html ) most likely as it fits the motor mount i am making perfect but if i use water for the esc it might be cool to use it for motor and esc.

Water cooling sleeve for NEU 2215
frozencpu.com has a large variety of PC water cooling parts
I'd use the jacket from OSE, large radiator from TCS and find a source for a high quality micro pump

[Ryu James]

i found a great site. frozencpu.com

check out this setup. tons of other options on the site.

The links for the water reservoir looks tricked out. I think this is all you need and the pump that they are selling. The TCS pump is small and looks real good. But it works good as long as you don't roll over as it needs gravity to feed the pump. Also you need a high volume tank for it to work as the more water it has the more pressure gets deliver to the pump. I tried it but it's very unpredictable on pumping water. You'll just find out it's not working when you check the temps on the water. When it works the temps is about the ambient temp of the outside but when not it gets pretty hot. Watercooling really works on cooling the motor, it's pretty amazing to see that my motor went from 170 degrees to 98 degrees on a 90 degree weather.

Jetdry makes an excellent coolant if you plan on running something like that. I use to build custom PC water cooling kits years ago. Done lots of research and testing on what works the best. JetDry is by far the choice. Also you could consider a Peltier based cooling system, they work so well that u can even have ice build up on one side of the cooling plate. Some videos here

http://www.youtube.com/results?searc...q=0&oq=peltier

This is a good example here on what u can do with it.

Its funny because u can make power with heat with a device like this.
