Hitec Aurora 9 transmitter

I mostly fly rc but have a few boats. Most of the time I use an older surface radio FM not 2.4. One application I needed 4 channels and was too cheap to invest in a 4 channel or better surface radio so I used my Aurora aircraft transmitter. I thought 2.4 is 2.4 but some on the forums started warning me about reflected signals off the water so I went with the Optima 9 channel receiver because it has dual antennas. Used it now for 3 years in the boat without a problem. Again 2.4 is 2.4 the aircraft version may transmit a stronger signal maybe not. I don't know but that combo works for me even though I only use 4 channels.

As far as output power, all transmitters are limited on how much power they can put out by the FCC. Therefore, a surface transmitter puts out the exact same signal strength as an aircraft system. In fact, the manufacturers use very similar transmitter modules in all of their products, varying only in how the information is coded and the modulator circuit as to band and how it is fine tuned to the exact frequency center, AM and FM normally using crystals while 2.4 uses something a little more high tech due to it's frequency hopping. As you said, 2.4 is 2.4, the receiver makes all the difference

I run a Spektrum DX3S system in all of my models, but I chose to use the Marine receivers in my boats because I was a little wary about the range. The Spektrum marine receivers have two antennas - so far I haven't encountered any range problems, however I haven't tested how far I can go before I lose signal. I just run the longer antenna as high as I can above the water's surface and the shorter antenna is left inside the radio box.

All kinds of guys locally running aircraft 2.4 systems in ground applications without any issues. Tanks and ground vehicles using half a dozen channels. Boats a few hovercraft, air boats even the odd warship with guns'pumps etc. I haven't heard anyone complain about radio problems.
