Help!
waterproofing electronics

Hi - I'm converting my Funcub to a water plane by adding floats. I've heard about applying Corrosion X to the elctronics but am not sure how to use it. Do I coat all the electronic (receiver, esc, motor, battery, servos) components internally? Do I open up the components to gain access to the circuitry? How much Corrosion X does one apply? Thanks for any advice.

I think most of the pilots who use Corrosion-X RED Label, just take the componets out, spray the Corrosion-X on and in the componets. Let them drain out, usually overnight. Many take the bottoms off the servos and spray those parts. Let the Corrosion-X drain out and then reassemble the servos.

I have used Corrosion-X on my rec and esc. I didn't do the servos, didn't have any trouble with the servos, but the next assembly of my Seawind, I will do the servos.


I didn't cut the shrink wrap off the esc or the rec. I just sprayed it in both ends and let it drain. Same with the rec.

Buy the pump spray bottle. Pour it into a suitable size container, like a foam drinking cup. Dunk the entire RX or ESC, and let it drain out for a day. I have not tried this with servos yet.

+1 on the use of CorrosionX.\

You probably shouldn't dunk the servos though. Only the tiny PC board needs treating. You can spray the board or use a small brush and paint the board with CorrosionX. You need to treat the servo wire exit point or seal it with Vaseline or hot melt. You should also consider putting Vaseline on the servo output shaft and under the servo arm to seal the servo case opening where the shaft exits.

Also, I Cx ALL connectors

Can;t see how you could get away with not doing so, because water will get in to them, then poof! Blue smoke comes out and that stuff is really hard to get back in!

I agree. The thing to do with servos is keep the water out. The only problem I have had with a servo was a result of water in the feedback pot, not the circuit board, and I don't think you should treat the pot with CorrosionX.

By the way, once I dried everything thoroughly and disassembled and cleaned the pot, the servo worked fine again.

The most vulnerable component, and the one most in need of CorrosionX, is the ESC, as it will fail if the throttle is opened while wet.
