    That's exactly what I did for the receiver in my airboat - opened the case to a cheap HK OrangeRX Spektrum-compatible receiver and loaded both halves with clear silicone, plugged a couple servo extensions into the board for the channels I needed to use, then put the board back in the case and closed it up. All that was left was to clean all the silicone off the case that pooched out through the seams when it was all pressed together. Air/water tight.

    And then I just bought a can of plasti-dip yesterday and used that on the speed control board, conveniently able to leave the heatsink exposed too. Works great for me.

    Haven't tried the servos... I guess I have another project to try lol. Ill tear apart a spare servo and see what I can figure out one of these days. On a positive the rx and esc's I have waterproofed have been running flawless (knock on wood) since.

    Conformal coating works well too http://www.amazon.com/MG-Chemicals-S...7255249&sr=8-2, I get it from Frys. I've also got a GPS that's been encapsulated in casting epoxy and it's worked perfect for the last couple of years, saw the Traxxas guys with one done this way. And for the servos I've started using the new waterproof Hitec ones, http://www.ebay.com/itm/Hitec-HS-564...item58919fb29d

    The acrylic would be a little stronger than the silicon, http://www.mgchemicals.com/products/419b.html. There's also a stripper if you need to remove it for any reason.

    Don't know if this has been mentioned before but this is "rubber tape" used for electrical splicing up to 600V. I'll have to try this on a 200A Birdie ESC I need to WP.

    Anyone ever use a hot glue gun? Seems like it may make a nice coating.

    I find it so easy --and effective-- to simply give my ESCs an overnight soak in CorrosionX, I've never tried any other means of waterproofing. If only the stuff didn't smell so damn bad.... :-)

    Take it easy,

    I have been using Heavy Duty Liquid Nails and then I go over it with Plastic Dip. Been working fine so far. Not the prettiest but gets the job done. Here is one that I just did and is drying. Takes about a day. Then I will put on the black Plastic Dip with a brush, both to seal once again and so it doesn't look so freak'n ugly

    Sure seems with all this work a simple plastic box and sealed around the inlets and wires would be just as good. You are already killing any possible air cooling the ESC may need and you are now keeping that heat in. Water alone is not getting all this heat out. Just my 2 cents...they make tons of different size small plastic boxes with snap lids...even small tupperware boxes are aire tight. Not sure you are looking for total submerging or just somethig to keep most water out if you blow a lid off. US plastics and others have any size box you can think of with snap lids. I prefer not to put all that stuff in an ESC if I ever have to get back in to it. KISS is what I like.

    SUCCESS! I waterproofed the control board on a servo, converting a video now and will upload to youtube tonight. The video is a servo, rx and esc all working submerged. The esc is hooked to a edf fan/motor.

    Rust-Oleum Leak Seal is the new great way to dip and seal electronics! Easy and cheap and may be removed if need. Walmart!

    It's in an aerosol can? How can you dip in that?

    Just use the traxxas RX boxes and be done with it. http://www.offshoreelectrics.com/pro...p?prod=dh-3628 I submerged one of these in a 5gal. bucket for a week and it had zero water in it and you don't need to peel all that crap off your Rx if you need to do something with it. Steve is out of stock on them at the moment but there are lots of places to get them.

    You really don't need extensions. Covering the pins while coating with DP270 or other is fine. If the connector and pins get wet, it's no different than the extension getting water in it. Just blow them out after a water incident.

    Dip it! It comes in a small can. There is a spray too. Stuff works great and can be removed.

    Not everyone has that much room to put a box in their boat. That box would not fit in any MiniCat boat nor in any mini rigger or mini hydro or mono. Plus it just adds unnecessary weight.......

    Correct. But you can even dip past the connections if you wanted to I guess.

    You can also apply over already sealed shrink tubed devices like a PisStix instead of dipping too as the shrink tubing is already great water protection. Take a toothpick and apply a little over the existing wires and it will conform easy. Dries evenly also. I'm really loving this stuff, so easy to use and works great and is flexible enough to last stress but not easy enough to scratch off or crack.

    I have used hondabond (high grade silicon...much better than regular silicon) to seal the end of heat shrinked items...so far so good. On my receivers and escs i used clear general purpose two part epoxt from walmart. thin coating. then i usually put dielectric grease on the connections.
