How do you guys do waterproofing for your receivers? I have a Bancroft 19" Catamaran (Motion RC RTR FE) and it comes with a balloon to put the stock receiver in. I currently have some electrical tape securing the end (where the wires exit) but I feel there is a better way. I've read articles where a 2 part epoxy is used to brush on both sides of the rx circuit board to completely seal it, is that true? Thanks,

Mark
