<snip> I have heard that the FCC here in the USA prohibits the use of model air plane frequencies for ground based toys and models (trains, cars, trucks, etc.). Chuck
It is no longer true with the (relatively) new 2.4 GHz spread spectrum equipment. Each spread spectrum transmitter & receiver have internal software that 'links' them to each other. That software also prevents 'links' being established to any other transmitter or receiver while in operation. This eliminates the need for specialized frequency assignments and crystals. Any 2.4 GHZ system can be used for controlling any device whether on the ground, water or air.
