Spektrum DX7 Overview
With the DX7 you’ll be able to fly anything from micro electric helis, to big gas-powered IMAC planes without regard to frequencies and free from fear of interference. Calling this kind of thing “revolutionary” just doesn’t cut it. It is nothing less than a quantum leap in RC technology that will change how you fly forever. Never again will the availability of a frequency pin dictate when you can take off. Never again will you have to ask, “What channel are you on?” Never again will your flying experience be interrupted by model-generated RF noise, interference from commercial broadcast towers, or anyone on another RC system.
