i cant find out how to waterproof an esc on the tips and info....would it be the same as waterproofing a receiver (corrosion-X....conformal epoxy?) and would i want to add the watercooling before or after i waterproof it? the coating might block the heat transfer and it wont be cooled as efficiently...

and where would one find a cooling plate as well? the OSE one is out of stock...(just in case it comes back in stock, what size tubing works with it? it says it doesent come with tubing...saleens7, the wookie of rc boating -
have you got a Dremel Saleens7?
if yes take a piece of plastic like plexiglass or so, 1/4" thick, with a 1/8" milling tip, make a route, U sor W shape something like 5/32" deep, depends how big you want the cooling plate, once you've done this, use a 1/10" thick aluminium plate and stick it and screw it to the plexi you've just milled, to avoid leakage, use a silicone (any kind of silicone) between plexi and aluminium, on the opposite side of the plexi, perform inlet and oulet holes, pickups can be a brass tube soldered on a thin brass plate, silicon again between plexi and brass plate and you'll get something like this
I've done mine with my CNC router but if you have a stand for your Dremel make an adjustable guide along witch you'll slide the plexi plate to mill!Comment

i think i see how you did that...i dont have plexy or amulinum....saleens7, the wookie of rc boatingComment

you don't need plexi, any plastic will do it, you can replace aluminium with thin brass, not as good for thermal transfer but not too bad if very thin 1mm max!Comment

what kind of ESC do you have to waterproof and watercool?Comment

i just go the supervee esc and motor from tom and i checked out the cooling plates....they might work...although they wont be able to wrap around the esc, they could just be glued on by conformal epoxy (thats the thermal epoxy stuff everyone uses to glue on cooling plates, right?saleens7, the wookie of rc boatingComment

no you can't glue a watercooling plate with the conformal coating resine, every conformal coating agent have bad heat transfert, they isolate from heat almost as well as for water!!! beleive me I've been in industrial Conformal Coating for several years!!!
to waterproof you have to hide or protect hot surfaces and critical components any connector, switch or potentiometer and then apply the coating!
What I would suggest is, assuming you have an appropriate cooling plate, apply thermal compound (same as for computer's CPU) between cooling plate and transistor's surface, put everything in a shrink wrap, shrink it, and seal it on both end with bathroom's silicon!!!Comment

trying to reproduce an industrial method of waterproofing with conformal coating is a nightmare, you're gonna spend a lot of time in preparation before spraying the coating!!!
we used to say that 5 minute of coating time represent 50 minutes of masking but in some case it's 10 time more!!!Comment

ok....so if i buy some cooling plates, i would glue them with a thermal compound and then shrink wrap it and seal the ends with silicone...ok...but where could i get some "thermal compound" to stick on the cooling plates??saleens7, the wookie of rc boatingComment

the thermal compound is not a glue it won't hold the cooling plate it place, it's a material that increase heat transfert, you can find some in computer shop, as I said it the white (sometimes grey when silver charged) stuff between CPU and heat sink, in electronic shop, commonly called heat sink compound or thermal compound!Comment

just a spot on each transistor or FET's and squize with cooling plate, done!Comment
