So why was it such a concern with 72mhz but not with 2.4gz at a lower power level? Theory is nothing more unless it is put into practice. Although I agree that you have more education outside of the hobby as eveidenced by the extensive resume you for some reason felt the need to PM to me, I have much more experience and at a much higher level in the hobby then you. Please keep that in mind.
Actually, when the Spectrum 2.4 radios first came out, they were a liability in boats. I saw several boats crash using them in water conditions that didn't seem to affect boats using FM and PCM systems on 27 and 75MHz. When the carbon fiber and carbon fiber reinforced boat hulls first showed up, there was issues where the radio signal wouldn't get to the receiver antenna. This was remedied by running the antenna out of the hull. This was even more important when using a 2.4 radio. In fact, some surface 2.4 receivers actually are shipped with an antenna over twice as long as a comparable airborne receiver for just that reason. None of this is theory, it's fact
