wet reciever

[mistel]

First post here

I have a small boat I have just built, and I was testing it before I have finished the cover . Of course, it got wet inside, now the radio does not work. No response, nothing. I took the rx out and opened it up, there is a bit of water inside, I tried drying it, and I will let it sit for a few hours to dry.

Any ideas on how to dry it? Is it fried?

Thanks

To the same kind of question, someone mentioned to use alcohol befor. Sorry I cannot recall where it was or which thread it was but i guess he didn't mean drinking alcohol. Pure alcohol like 99.99%. Industrial one as well.

Alcohol MIGHT work, the old stand-by hair dryer can't miss. I've dried out a few receivers using a hair dryer, and can attest that it works.

Expect to get a bit of water in your equipment from time to time. It happens to the best of us, sometimes in spite of our best efforts to prevent it.

The good news? Your receiver probably isn't fried. These things are remarkably durable and take a lot of abuse before finally checking it in.

Man, what I wouldn't give to be able to build a good radio box. LOL. Studied pic's of quite a few and still get a tad water in there. Sooo, my Rx gets a coat of AeroPlate along with stuffed in a balloon w/paper towel and stuff paper towel in the radio box as well.

If she does get wet, like mj40 said, a little blow drier or a sit in the sun usually does the trick.

Anyone up for giving a class? :)

The solution is to have a dry boat inside, this makes waterproofing the receiver unnecessary. :rolleyes: There really is no excuse for getting much water into a hull - unless it is holed.

* Hatches should be taped down so that no water enters.
* Drivelines should be sealed with silicone tubing (or thick grease in some cases).
* Antennas should be sealed at the deck.
* Switches should be sealed inside the hull.

You should be able to tape the hatch down, hold the boat completely underwater for one minute, then open the hull and find little to no water inside.

If you get your receiver wet, take it out of the factory case and heat it up with a hairdryer. Don't get it hot enough to melt anything! Let it sit overnight, and it should work the next day. If it does not, then it is probably damaged. Hint - make sure that the servo is working, if they get wet they won't work well even if the receiver works fine.

The idea of getting no water inside the hull is a great one--- for electric boats.

For those of us running nitro or gas, there's no getting around the need for openings in the hatches that can allow air to get in for the engine. Unfortunately, those same holes also allow water to get in when you flip the boat (it happens) or -- some hydros tend to settle really low when the engine stops.

So, we try the next best thing to a dry sealed hull. We use (supposedly) watertight radio boxes or watertight compartments. Some are better than others, there are those who seem to have relatively dry radios after an incident while others have a box that bears an uncomfortable resemblance to a fish tank.

That being the case, I'll take all the waterproofing of radio gear I can get. I'll also keep a hair dryer on permanent standby "For just such an emergency".
