I have tried to find a waterproof remote control as well, with no luck. In Norway we have broken two of them due to rain. The good news is that they are “off the shelf” from your local dealer. The bad news is that it takes half a day to program them, and that is if you do it correctly the first time! (I broke the first of them myself. It did not even cross my mind that it could not be waterproof)
On a side note: It is possible to have several setups on them, so that you can use the same remote for the ARC boat or the rQpod. And for the rQpod, it shall be possible to program it so that you have both trottle and turning on the same stick. That would ease one-person operation!
