Castle Creations Hydra 240
 

Anybody know anything about Castle's newest hydro esc

http://www.horizonhobby.com/Products...ID=CSEHYDRA240

Its water cooled and looks like it can handle 20 cells and 240A

I may just have to try one since the MMM is still a ?

Weird thing it's not on their site...

Looks like a nice controller! nice current handling.. :)

But what about the brakes? i think it might be necessary to use mechanical brakes with this controller.

Ya, I basically stumbled upon this tonight.
Don't boats have brake... lol
There is a 120A and 240A. The 240 looks pretty good for only a few bucks more.
Its water cooled so that could be pretty handy for those hot summer days :017:

It shouldn't be too hard to make it work with a normal heatsink.

The 240A should be more efficient (lower internal R (assuming they use the same, but more, fetts than the 120A version))

Boats and brakes;

Boats usually use soft brakes, compared to land vehicles.

And the timing of the motors is more aggressive, but they are pretty close to cars.. Closer than planes for a fact.. (like the phoenix you tried)

Bytheway; have you seen that little thingy that makes a stick controller work with a pistolgrip transmitter?

I haven't seen the pistalgrip adapter. You got a link?

Bugger, can't find it back anymore..

Anyway; it was an inline convertor, it basicly changed the input signals on the controller to accept the pistol grip.. It changed the 0 point of the transmitter.

Oh i see how you are
You're such a tease ;)

I wonder if a small fishtank airpump would be effective enough rather than use water. At least there would be airflow. :)

I don't think dragging a 110V generator gives you better laptimes though..

Can't find the convertor anymore.. I will continue looking but no luck so far..

YEAH!

found it!!

Here is the little bugger..

lol, well, if left at 110v no. But all it would need is to replace it with a 12v dc motor. Small and low amp draw...

Usually, they don't use a rotating motor Brain!

Cool, Thanks
I picked one up to try out
Who knows, maybe I'll give the HV110 another shot :017:

This saves me money Star! thanks for testing.. :)

No Problem, what are friends for :027:

I just wonder if this is just a water cooled version of the MMM :028:

Really, the little one for our old small fishtank uses a rotating motor with a mini compressor thing...

@star; That might be!

I only hope they go higher on the voltage.. Current sounds good.. :p

Brian; i only know them as a vibrating membrame, powered by a non rotating motor.

At any rate, it was a tongue-in-cheek suggestion anyway. :)

water cooling would be nice on hot day indeed! It's just a matter of shrinking those pumps down, and low power like you said.

I wonder, for PC chips now they are going for these new nano pumps, they don't use any power! Something to do with tiny tiny ridges inside the thing that makes water run in one direction! They would be paper thin too. then all you need is a light wieght radiator, which is kinda of an oxymoron; but still you wouldn't need much to dissipate the heat from an esc...

Zero

Bah, just give me a larger heatsink or a more efficient controller! The more "stuff" you add, the more chances for something to go wrong.

Just fill it full of liquid nitrogen and call it a day. :032:

I would estimate the Hydra 240 has an ultra low resistance somewhere around 0.0005 ohms

Ya, I hope the MMM has similar voltage capability as the HV line. :018:

Why not use that water cooling system that Nick, I believe, posted. The radiator is pretty small as well as the pump. I believe the pump was only 12 grams and about the size of a dime.

Really? 12 grams

Could you link me please.

Unfortunately I just reformated my harddrive and lost all my favorites. :( I'm gonna look for it now though....

KK, thanks, im kinda interested now. I could possibly make the rear connect plate a radiator, and somehow make a water block for the Quark contoller, right inside the esc case, instead of the alum. heat spreader?

might work, little risky though...

Found it!

SWEET! Thanks for the link Squeeforever.

That is amazing how they got it so small! I suppose there isn't much to a vibrating pump... I wonder if you can buy the parts individually? I would love to put that radiator up front on the chassis braces, up out of the way of flying stones.

I've always wanted water cooling, up until now there hasn't really been an efficient way of doing it!

Thanks squee,
The TCS system looks sweet. :017:
I wonder how much it adds to your over all weight.

No problem. It only adds about an ounce...They tell the weight of all the components...

It's too small to work properly IMO.

Do you mean like the amount of heat energy it can take away?

Well if that pump has a decent amount of flow rate, then it would work very well.

I'd like to see an tube water jacket though, to go around the motor. boats have jackets, but they are just coils which have crappy heat transfer.

I think computer CPU water cooling guys should be helping out there.

I just thought of it, does anyone here know what a heatpipe is? That would be nice to have a heatsink using heatpipes for a motor.

Run a more efficient setup and you don't need fans on the motor to start with. (neu) the speedo might need a fan, but with a fan the problem is solved allready. Which weights less than a fluid cooled system.

With 'too small' i meant the radiator. You might need a fan on the radiator to do its job, and with that, you are just transporting heat. (which is the basic of a liquid cooled system, transport heat to a larger area/different place )

Yah right, kinda defeats the purpose huh. The amount of money you spend on the thing, you could have bought a more efficient motor...

With all the advances in semi-conductors these days, we are fast approaching room-temp super conductive materials. that will be the day :027: :017:

I find the humor of the radiator on the various water cooled rc vehicle that I have seen. The chassis on most converted vehicles is al, which is an excellent conductor of heat. Why not use some thermal epoxy and glue an al tube around the edge, or in an unused area. Use about 12" and a small pump that would slowly move the water around. It would not weigh much. No need for a radiator and fan IMO. You may be able to get away without using a pump, possibly some glycerol? and hope that it would thermo siphon.

Fine designs' setup is my favorite. Add a water jacket, extra battery, lines, pump, raditor with fan, etc. Why not use a lower kv motor and put the money toward 6s lipo? That would run cooler, even with a feigao motor. Like a 10xl? Put some clip on heatsinks on the motor too, everything helps. I would like to try a hydra controller, but it only handles 6s, so a quark air esc can do that.

I'm still thinking about getting one of the TCS setups. I think it would work decent, but I guess the only way to find out is try it. The main advantage I see is a cooler running system, if only slightly, which could allow you to have a wider array of gearing choices. Maybe use something like the 9920 marine and make use of the tubes that run through it...I'll probably try one on my BPP LSP. I just might help with heat, since it gets pretty damn hot in the summer around here...

I am completly sold on HV setups and will only run HV from now on.

I am running 8S A123's and the CC HV110, with the pistix Serum referenced earlier, and I don't even break 100F in racing conditions.
I run this setup on my 8ight, G2R, and MBX5T.

My only issue is throttle control with the HV110 but I am getting a better handle on this over time.

My hope is that the MMM will handle 8S A123's. That is... if the MMM is ever released

Agreed. I like HV as well, only issue that I have, that you probably don't have, is it gets well above 100 degrees frequently around here. I hope if I try the water cooling, it will let me keep it nice and cool in the summer.

What is the throttle control like starscream? I have a hv 85 and plan on using it in my aftershock on 10s.
