Save reciever from water?

[Stoomstrijkijze]

Hi guys,

I was at the track today and it was a bit wet. My ESC and electronics were fine, but I forgot about my reciever. At one my moment, I couldn't control the car anymore. I was running at 1/4 throttle but I got stuck some where so I was lucky. I checked the whole car but I didn't found anything. I tought it was just bad luck. I started driving again and when I ran out the pit, the car went his own again. Now with more throttle and hitted a pile and the car got damaged unfortunatly.

After that I tried to see what it was. The ESC of the receiver. When I tried to bind my receiver again, nothing happed. The light should start blinking when in bind mode. I opend the case and I saw no water, but the paper sticker inside the case felt a bit humid. I took the aircompressor and started blowing on the PCB. After that, the reciever would bind again. I throwed it in a pot of rice now to make sure all the water is out of the PCB.

But now I'm scared for corossion on the PCB and to test the reciever again. It always works perfectly on the car stand, till you start driving it on the track...

Should my receiver be fine? It wasn't soaked in water. It can be more than a few splashes.
When it works/bought a new one, I'd like to waterproof the whole reciever. What are my best bets for this? It's the stock reciever for an Airtronics M11x that I have in my buggy.
