Are there other ways to protect from water ? These recievers are costly. Regards Andris Golts.
Andris,
What I do with mine is to add 2" or 3" extension pigtails to the plug sockets, use some clear waterproof packaging tape to cover over any openings (like the plug for the battery if using a BEC ESC and the crystal hole, etc.), then I dip the whole unit in some lightly thinned clear "Plastidip" tool dip... I sometimes use a small artists acrylic paint spatula to smooth the dip out and wipe off the excess, then place the whole unit on wax paper on a flat surface to dry overnight... The next day, you'll want to carefully peel it off the wax paper and lay it on it's side to let the bottom completely dry...
This gives you a nearly waterproof RX, and the bottom ends up very flat and will hold industrial strength velcro very well... Haven't had one fail yet...
If you have one with adjusting pots for changing frequencies, just tape over them with the clear tape, dip in the coating, let dry, then gently make a small slice in the area where you need to make the adjustments... You can usually get a small screwdriver in there and the tool-tip closes right back up again when the driver is removed...
Hope this helps...
