Water cooled mamba xl2

They are a copy of the castle unit but much cheaper.

If you go to SkyRc's web site they will show you the internals, very different from the Castle but, thats just my opinion. Good deal at HK.

Newer version, very different: http://www.skyrc.com/index.php?route...product_id=209

Interesting internal layout, still, I wouldn't have the ability to water cool it.

Thats a totally different version. The version sold by hk has the same layout as the castle.

Do you have a link so I can see how the internals are laid out? I'm not afraid to buy one and convert it.

Interesting, my bad.

Here you go. Scroll down about 3/4 of the page. They are pretty much exact copy of the castle.

You can see how the fets are closer to the middle and the heatsink actually touches the metal bars beside the fets. I will beusing thermal rubber to better pass heat from the fets. I wanted to use copper foil since I happen to have a ton of it but that would short out the esc.I put an ohm meter on the metal strips and they are connected with the motor wires.

I took a look at mine. It looks like a leftover SF 200a wc plate is a great solution for the castles. I have some pics. When I get a chance to crop and load em I will show what I did.

That board looks exactly like a hydra 240 and mamba xl2. I want to buy one now but I wonder what programming software it uses and if it data logs like the castle.

Off the top of my head I dont think it does data logging.Its not a huge deal for me since the data logging on the castle units in general seem to have a reputation for being in accurate.There is a program card available for them. I wouldnt be at all shocked if the castle software works on them since its an obvious clone.

Cool, I have one of those here... Thanks

I removed the little heatsink under the driver board. Moving the caps out of the way, the sf plate fits perfect.20150307_095930.jpg

It looks as though .5mm thermal pad on either side and the two pieces will be a perfect fit. All that's left is to mill out some fines on the other half of the HS for brass tube. Providing of course I don't come up with something better.20150307_100139.jpg

Ok here is what I came up. Unfortunately due to the small amount of travel on my tiny lathe it will be a huge PITA to mill out the fins. 20150307_150222.jpg
So I am going to use the stock fan only I will drill a couple large holes in the sink so the fan blows directly on the fets rather than just on the HS. The top half of the sink does a better job of contacting the fets then the lower half so doing it this way should actually work out quite well. It has thermal protection so should it not be enough cooling it will shut down. But honestly between the water plate on the bottom and the hs/fan on the top it should be fine.

Looking at the trackstar unit I should be able to do pretty much the same thing only with dual fans. The boat it will be going in can handle the tiny extra bit of weight. I just need to get my mitts on another SF cooling plate.

If you need something made let me know. I also have a hydra 240 top that I milled the tube slots bigger for bigger tubing. It's still rounded.

Thanks. I could do it if i really wanted. Just means milling so far and then undoing the vise and relocating the part to mill the rest. Its only a taig lathe so even setting it up for milling is a bit of a pain. I won,t do it unless I absolutely have to...
