    DP270 Confrmal coating.

    The old days we would put a small piece of sponge under the flex stuffing tube to absorb the water dripped in at the flex.

    I started using the aeromarine flex shaft seal on all my builds. Water up the shaft is a thing of the past.

    Hello I have been flying planes for over ten years , than I came across a guy who takes his esc. apart, removes the cooling plates and incases it in JB weld and the darn thing runs cool , so water proofing, I think so. It just seems foolish to buger up a new esc. Myself wanting to try a boat out on 3 cells to 4, just to see whats, what; I took a Hobby Wing 100amp. esc. out of one of my planes, unscrewed the for top screws, took a cooling plate with water inlets from a burnt out esc. placed it on top of circuitry, screwed the top "blue fined" plate down, and than "entombed" it in hot glue, and shrink tube. Hey it worked great, and yes there was water in the boat, HA HA I used hot glue so I didn't destroy the esc. Cleaned up the esc. back in plane and ordered a marine esc. So yes use J.B.weld.

    I would imagine jb weld has some conductivity to it...it has bits if metal in it. I've been using 5 minute epoxy with good luck.

    Cool

    l picked up a 120A Suppo airplane ESC tthe other day. I popped the cooling fins off of it and replaced them with an a nice water cooling block, and some PC thermal paste on the FETs for heat transfer. I wrapped the ESC with HVAC Aluma tape and was able to pretty well seal it up. then I finished it off with 3-4 kotes of spray on plasti-kote. it turned out pretty damn good
