Anyone used the Mystery 80 amp ESC?

I've been thinking about water cooling for the ESC's. I have one of the Mystery 80 amp versions in front of me here. I've always wondered why they would completely enclose a heat sink inside shrink? LOL

Anyways, I need a Copper cooling block that water circulates through. Unwrap two of these ESC's, then "sandwich" the cooling block between them using heat sink compound between the block and the Fet's of each. Then the two ESC's can be heat shrank again to hold the entire thing together.

I'm hoping this will provide a nice compact answer to dual water cooled ESC's.

I have a pair of Mamba Max ESC's that I could use, but I see no way to water cool them without really messing them up. They are just too good in the Monster Truck realm to do that to them.

That sounds like a good idea. I have seen a few al cooling blocks made, basically you drill a series of holes through the long side of a decently thick piece, maybe 4mm holes in a 5mm thick plate. Them drill acoss the top and bottom to make a series of connected passageways. Them block off all but two of the holes with setscrews. Use some sealer on them so that they are water tight. Leave two holes opposite each other for water input and output. Them use some thermal paste and heatshrink it all back together.

Thanks for sharing that Linc. I have everything to make the cooling block now that I see how to do it. Well except for the little nipples that the cooling line hooks to. Any suggestions on those?

You've ran the Mystery 80 amp esc. Do you think it would work well for this?

You can get the nipples from aqua craft, but you may want to look around the hardware or auto parts store. I would use some small brass fittings from the auto parts store myself.

The mystery 80 seems fine, most air escs seem to work the same, and quite a few boat guys use the mystery escs with success. I think I paid 40 shipped for mine, so the price was right! Not much startup load, or spikes with a boat so you just need a decent cont rating, and 80 amps seems fine for your application.
