I know offshoreelectrics.com has a motor mount to support the rear of the 2215 motor.

It looks simple you could probably make one yourself if you could get some stock

Do you think the 25C 5000mah Zippy batteries would be adequate? Or would the 30C be safer?

I think the 25C would be fine, especially with such a low turn motor.... you figure, I pushed mine to do crazy wheelies with a 100A cheapo esc... You should be good my friend, if the specs on the lipos are correct... But doesn't hurt to go higher C ratings..

how much are they? i am not familiar with the zippy packs. i have both 25c and 30c packs and cant tell much of a difference. btw, if you are interested i have a couple of 10s 25c 5000mah thunderpower packs. they run $560 new but selling for $225. let me know if you have any interest.

but i think you would be good with either one.

castle hydra hv 240 is here!
 

WOOHOO!! got my speed control today. here are some pics. i also found a little ABS box at radioshack that will work perfect to mount my esc and rx in. i will mod it so a fan will sit directly over the esc and hopefully that will be sufficient to keep it cool. it is normally cooled by water. i plant to make a new center top plate out of carbon that is large enough to mount the esc to.

been working on the swaybars. should finish that today and will post pics.

Thats a big speed controller!


As for cooling ideas.. maybe you can take off the water cooling plates and put heatsinks. Maybe take an aluminum box and fill it with mineral or silicone oil and submerge the esc 100% of the heat energy transfered away.
maybe just sync the esc to the chassis with thermal paste.

Because with the water cooling plates you just dont have the surface area of a heatsink to dissapate the heat energy...

just my .02

Well the cooling plates are inbetween layers of boards sitting on top PLENTY of FET's. He would have to unsolder the layers to pull the cooling plates out.

I think it will be fine. I don't think your amp draw will be as much as the controller is rated for. SO i don't see it being a problem. The cooling plates are ALU as well so they will inturn act as heatsinks anyways.

Ryan, she's beautiful isn't she.... :)

thanks for the ideas. nitro is right. there are 4 alu. plates inbetween pc boards and the alum. plates are connected to alu. pipes extending in both directions which are normally used for water cooling. i thought about just removing the shrinkwrap so that a fan can put air around all the aluminum but i am not going to do any mods yet until i try it out. i dont want to void any warranty if i dont need to. Mike has said the the hv 180 has been working fine on the brushless baja he built so i am hoping this works out. if its running too hot then i will look at doing some mods to cool it down. i am thinking with one fan on each the motor and esc i will be able to use gearing to get both temps within the ideal range. i hope so anyway.

Hi Ryan, since you bought that box at radioshack, it includes a metal and plastic top, right? If you remove the water cooling bits, you can thermal epoxy the esc to the metal Case top, then epoxy a large heatsink to the other side of the top.

yes, that is right. it has both a plasic top and an aluminum top. however, after working on it today it appears the stock rampage rx box is gonna work better. it is slightly larger and will fit both my esc and rx comfortably and will be easier to mount. the RS box was just too tight of a fit. it would have looked real clean though. plus, with the rampage box i will be able to water proof it i think, even though the esc is already water resistant.


ha, i just said "box was too tight of a fit."

Oh, get your mind out of the gutter young man! :lol:

maybe you should ask pdelcast what he thinks... after all he designed it

If you're going to have a fan on the esc, have it blow into the alum pipes, simpliest and probably most effective. Careful wire routing would be required for this to be most effective. Removing the shrink will probably help a little too, and I wouldn't think it would void the warranty unless you solder on it. Besides, wouldn't running it in a land vehicle without the water cooling void it because it's not being run within it's design constraints?

On the more radical side I'm curious how effective a heat pipe system would be. It's what almost all pc cpu coolers are going to now. But that'll definitely void the warranty, and the aluminium pipe don't dissipate heat as well as the copper ones used in cpu coolers.

heat pipes! thats it! 8 heat pipes on 1 heatsink. perfect

what are heat pipes? are you guys just referring to the 8 pipes on the esc?

what about this? i thought if i could find some kind of little pump i could mount a small nitro tank on the chassis with some coolant/water in it and use fuel line to pump through the esc pipes and back into the nitro tank. i just dont know where i would find a tiny pump like that. i am just gonnna stick with the fan but this would be kinda cool.

How about a washer bottle motor from a 1:1 car, pumping coolant?:neutral:

cool stuff, each layer has it#s cooling.

one possibility would be to remove the pipes, grind the remaining surface flat, and put a heatsink on each side (w/ thermal glue). but this would probably void the guarantee. and is too much work.

or you could get yourself one of those water cooling systems for rc-car motors. yes, I'm not kidding!! I've seen them already a couple of times on the internet. It's mor or less the same like 1:1 cooling systems. and you have plenty of space on your car. water is actualle much better for cooling then air. here we go:http://www.rcuniverse.com/forum/m_5375253/tm.htm
get that and you have the most unique bl-converted truck on the planet!:yipi:

an other strange but probably effective Idea:
you get massive aluminium (or copper)-sticks which fit tightly into the tubes, probably together with some thermal paste. the sticks would be longer than the tubes, like that you have more surface. maybe you make the ends of the aluminium sticks flat, so you can glue a cpu-heatsink on it. like that you have much more surface for cooling purposes. and it can be removed easely.

or you put a little fan on each side, right on the tubes. so the fans cool - instead a heatsink - the tubes. it would look a little bit like those mgm esc's.

i have seen a pump small enough but i dont know were to get it

Ryu this thread is becoming a sticky- insane build and the disc brakes are too cool!

I think you are onto something with a tank/pump setup and my suggestion would be a windshield washer fluid pump. Any auto parts store will have multiple units to choose from, a small 3S lipo (like a 800- 1320mah) would provide the 12V. Only possible problem would be that these pumps are made for intermittent use. Check Edmund Scientific for some small project type pumps as you would only need very light flow to be effective.

We will need some video of this bruiser ASAP!

Ryu- This has been done before when a guy used a boat ESC in a vehicle. I'll try to find the thread on his build. He said it worked very well. He used a small pump that put out like 10psi and a small tank.

A larger nitro tank, some al tubing arranged in a zig zag pattern with possibly a fan to blow air over it, and a small pump would work well. As long as it is setup properly a water cooling setup would not be very heavy or very big, but finding a pump that can handle a beating may be a challenge. A car w/s washer pump would be a good choice, they are pretty sturdy, and you could mount it to the side of the nitro tank with some creativity. No sure what voltage to run it on, as they produce a fair amount of volume on 12v. Maybe 6v off a ccbec or something like that. If I get bored I may make something!

you can get a radiator.
and a pump http://www3.towerhobbies.com/cgi-bin...?&I=LXDJR7&P=7

I'm pretty sure thats the one the guy used... Good find!

Yeah emaxxnitro hit it right on the head!

cpu-modding-cooling
 

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
http://i183.photobucket.com/albums/x...n/SSPX0064.jpg
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:rofl:

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

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.

watercooling
 

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.

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:

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.)

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

i found a great site. frozencpu.com

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

watercooling
 

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.
