I'm just starting out. I've had 5 serious crashes and 3 succesful flights. I live on a lake and fly floatplanes. My last plane was a Seamaster which I wrecked last week. I now have a Mariner 40 with an OS 46ax, which I will fly this weekend (weather permitting). My reciever got wet on every flight, especially the uncuccesful ones. But even the good flights, we ended up with some water inside the fuse spashing around. I have been able to dry the reciever out every time but I have a feeling I have been lucky. Is there a way to waterproof the reciever? Thanks for all your help. You guys are the greatest.
