Waterproofing esc

[Cooper]

Ok guys I've got another question, I would like to see and know how any of you waterproof your esc's. I'm thinking of several ideas. Corrosion x, plasti-dip, encasing , ect. I was thinking of dipping a esc in liquid tape, plasti-dip. I usually just spray with corrosion x. I'm curious what others do. ( and yes I always take great care to keep water away from esc, tape, sealing hatch, ect...)

Silicone based conformal coating.... We have it here in Renton at the local Frye's store... Clean and dry the ESC, then brush it over the circuit boards... Let dry and apply two or three coats...

Doesn't help on the controller board connection, however, if it has a plug-in controller board (Castle, etc.).... for these, I fill the socket with Dielectric grease to help repel any water...

The ones I'm thinking of doing are cc ice hv 200. Can't really open it up to the board.

Warning,warning!!! I used MG Chemicals Silicone Conformal Coating on my Ice 200's and the heatsink compound let go.This happened to 2 of em. Granted I was fairly liberal with the spray but just saying. BTW in doing this I have seen these sure could be alot smaller with FC heatsinks or even some others.

Cooper I have been doing the Liquid tape on all mine.Just go over them after dry and make sure there is no little air bubbles that water can find it's way through.

IMO Attempting to waterproof your controller can lead to a false sense of security. I've fried a few controllers when attempting to use them while wet. Even the so called water resistant variety. If your controller gets wet, discontinue use, spray it down with corrosion X, WD40 or alcohol and let it dry for a few days.

srislash is right... that stuff will eat right through the high-temp heat transfer compound used to keep those heat sinks on.... On mine, I take them off and add some custom water cooling plates, so I conformal coat them first.

However, Chili is right as well... I never expect them to actually have to repel water... I keep the inside of my boats dry. That's the best way to go.

For the boats that I can keep dry, I use spray-on electric tape just in case a hatch gets peeled off in a crash.

For the boats that run wet (my tunnel and shovelnose hydro get a fair amount of water in them), I use either Aquacraft Marine ESC or the Proboat ESCs-- those things are pretty darn "waterproof"-- I've had both completely submerged for quite some time and they have survived... all I do for those is touch up the ends where the connectors enter the case with liquid electric tape.
