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.
