I had a hard time getting my radio box to seal up so I decided to look for alternative methods to protect my Rx systems. Afer asking around I found the CRC Heavy Duty Corrosion Inhibitor. It's designed for protecting your electronics on your fishing boats against saltwater spray. I thought I'd give it a shot. One day at the pond I lost control of my throttle because the servo got a little water. So in the field I took the servo apart and let it dry out for a 30 min. Then I sprayed a heavy coat of the CRC all over the entire inside and out of the servo. I assembled it and reinstalled it and never had a problem again. Only the 3rd channel got wet and malfunctioned next and then the steering. So when i got home I decide to do a little test. using a few extra servo I had lying around I tested this CRC spray. first I dissassembled the servos and the receiver.
Then I sprayed a heavy coat of the CRC CI (Corrosion Inhibitor). I let that dry for about 30 in then added another coat. After 3 generous coats ont he electronic circuit boards and the casings put all the gears back in and added a dielectric grease to the gears and a full coat to the entire Rx.
Then I reassembled everything and used some CRC Electronics Cleaner to clean the outside of the cases. I let everything dry for a few hours and took it inside to the kitchen. I filled a bowl with tap water about 2" deep. Then I hooked everything up and made sure it was working properly.The green light on my Rx shows that it's receiving a signal from the Tx.
Next I dropped the entire Rx system in the bowl and watched for any servo glitching or a loss of signal.
Everything checked out great. I activated the servos using the transmitter and they worked just as they were sitting on the table. No glitches no interference. I waited for ten minutes watching for any signs of water intrusion all the while manipulating the controls of the Tx. and not a single twitch. I ever checked my F/S by turing the Tx off. The servos moved to the F/S position and then returned to nuetral once I turned the Tx back on. Perfect!!! Since this test I have waterproofed all my electronics and have never had a single problem. Even after a few blow overs where the boat was 3/4 under water for 15 min I had no problem. The great thing is if I ever do have a problem all I have to do is dissassemble everything and use the CRC cleaner to clean the parts the redo the water proofing and I'm as good as new. But I have yet to have a problem with this method. If you still want to have a r-box this is a good way to be 100% sure you'll never loose control. a run away boat can be disasterous and even cause bodily harm. Easy to avoid, takes $10.00 and about an hour.
