| 2.4GHZ Under water
Anyone had any luck running digital under water? I have heard mixed emotions about this and I am wanting to get more input.

my old FJC was definitely a Submarine. It worked for about 2ft under water.

I've had my VXL powered scx-10 at least 6" completely under water and I had to stay right on top of the rig or the radio wouldn't work, I'd be leary about going any deeper. Just out of curiosity, I wonder how the RC submariners control their rigs? |

It has to do with the wavelength of the signal. 2.4GHz frequency has a much shorter wavelength than 27 MHz and can't penetrate the surface of water. That is the reason that the US Navy nuclear submarines use ULF (Ultra Low Frequency = longer wavelength) for underwater communications.

| Some run a wire off of the sail that floats, its good for a couple of feet under water.

Thanks for all the input I may set it up so that I can just switch out the receivers easily and put the fm in when I run in the water.
