In October of 2004, Horizon Hobby rocked the RC world by unveiling one of the most revolutionary products to ever hit the market: Spektrum 2.4GHz Digital Spectrum Modulation Technology. Similar technology in the computer and telephone industries has eliminated interference, increased signal resolution, and provided a stronger link between the base units and the transmitting units. Since then, racers and now pilots have embraced Spektrum technology, and the future is even more promising.
