Hi i just purchased 2 Futaba R153 micro receivers for my electric boats up to now i have been mounting my cheap am receiver s in foam velcro ed up off the the hull floor as we all know sooner or later water finds its way near radio gear years ago i put recievers in balloons which was a nuisance . Is there such a thing as a waterproof reciever box ? Are there other ways to protect from water ? These recievers are costly. Regards Andris Golts.
