Seaking 180 ESC Waterproofing

[Bullwink]

Thanks guys. I opted to leave the heat shrink on. I used liquid tape to flow into the esc and then sealed the ends in silicone.

I always use conformal coating on my esc and recievers . It is sweet it dries clear and you can solder through it.....

The last thing I got interested in before trying RC boats was RC float planes. I had been flying RC for many years, but finally decided to try flying off the water. I learned right away that water and ESCs did not get along. The typical solution for a lot of RC flyers is treating the ESC by submerging it in a cup of CorrosionX overnight, then letting it drain for a day before using it.

I don't believe I've heard any of the boaters here mention using CorrosionX. I think the stuff is a miracle, personally....

You have obviously missed the discussions & mentions of Corrosion X on this forum, this stuff is probably wider used & mentioned on this forum than any other around. Its also in the OSE store.

Can you just use silicone sealant? Plasti dip is hard to get in the UK and about x3 the price! I've got a tube of black sealant at home.

I use black ultra silicone sealant. So yes you can just use what you have.

In the UK plastdip them selves sell on Ebay. Re silicon, yes you can use this as well. The problem with any sealer is where your moving the wires around on the esc etc you break the seal around the wire & you dont know whether its still water tight. If water does get in then it just sits their not drying for a long time. Silicon must not be the acid type,you know the one that smells of vinegar as that will corrod the whole esc over time, you need electronics grade or one that dosnt have acid in it. With Corrosion X you simply treat it & its good to go, you can then give it another coat anytime later ecspecially if it does get wet.

You can use anything you want as long as its a sealant and has decent dialectric capabilities. But you might consider the issues with using "goops". A thin water proof membrane allows heat to travel off the boards much more efficiently. Thick covering retains more heat on the components that generate heat. If your ESC survives your setup and continues to run over the years you need to consider that heat alone is the one major factor that kills speedos. Getting them wet is up there too but the quality built speedos are not encaspsulated, sealed in a mass of some elastomer. They breathe so to speak or at least allow heta to escape as much as possible.

if the silicone is acetone based it will ruin your PCB (according to ben)

[Bullwink]

Right. I saw that. So I made sure the silicone I used was not acetone based. (I think :-) )

I just let all the smoke out of a brand new Seaking 180 - not impressed with a device supposedly built for marine applications.
No, I didn't seal it - why should I have to if it's constructed correctly?
Pretty pink smoke covered the lake - looked like an emergency flare went off - laughed 'til I cried!
Got a Hydra 240 XL on order. Hope it has better engineering for preventing "liquid lightup".

Guys u might want to look into this . I just started to use this and it works great http://forums.offshoreelectrics.com/...ht=#post415457

Question: Should I cut the stock plastic covering off of the ESC, coat everything in liquid tape and then spray it with plastic dip or, should I leave the stock plastic on and just try to waterproof the exposed ends with liquid tape and black silicon caulk?[ATTACH=CONFIG]67333[/ATTACH][ATTACH=CONFIG]67334[/ATTACH][ATTACH=CONFIG]67335[/ATTACH][ATTACH=CONFIG]67336[/ATTACH]

I cut the shrink off my Swordfish 200 and used PlastiDip but it's a real mess...in hindsight I should have just plugged the ends and coated with Dip...JMHO.

I have a silly question, has anyone sent one of these back for repair after waterproofing it?

[traeside]

it says version 2, Does it matter?

I know it's suppose to be waterproof but it definitely is now. Here's the pics after the electrical tape has dried.

Howard, have you submerged it yet? i followed what you did here but i must have missed something sense after about 15 minutes in the water the case was about ½ filled with water and I could not get it to drip out tell I removed all the liquid tape and the screws then I dumped all the water out. it is now sitting in rice for a few days before I try it. I saw somewhere one guy filled the whole thing up with the spay liquid tape.
