I have been working on my USS Hawaii for the past year or so, and I was lucky to be able to find a 75mhz Hitec 6 channel last year on ebay when I was doing my build. But I have been wondering about the 433 mhz band. I know 2.4ghz wont work for submersion, but what about 433mhz? I have tried google for information but haven't found a definite "will work" or "wont work" answer. Intuitively, it would seem that you would not have quite the same ranger or be able to go as deep, but it has never been my plan to go very deep. Our boat club - Indy Admirals, sails at the Carmel reflecting pool where the subregatta is held so max dive would be maybe 2 ft.
Really, I should just stop wondering try it. I recently got the 433 mhz transmitting module and two receivers from Hobby King. One I used to fly my hexacopter yesterday, but I still have an extra. My transmitter is the Turnigy 9x with the er9x firmware. I just haven't had the time to put it in my WTC and try it in the bath tub. There are obviously a lot of smart people on the discussion, and I am wondering what your thoughts/speculations/experiences are with using 433mhz.

It is a low power (100mW) transmission and should not bother other HAM operators since it is frequency hopping. Once I get a chance to test the water penetration I will report back here.
