Spektrum DSM Technology was unveiled at the 2004 iHobby Expo at the Donald E. Stephens Convention Center in Rosemont, Illinois. At the show, the overwhelming question from attendants was of course, “When will it be available?” The first releases were a series of modules for existing JR, KO Propo, HiTec, Airtronics, and Futaba radios that allowed racers to enjoy the crystal-clear and reliable signal provided by Spektrum technology without requiring them to purchase separate radios. Spektrum modules and receivers were tested at a number of high-profile events to ensure that the technology worked. From events such as the U.S. Indoor Championships in Cleveland, Ohio to the IFMAR On-Road Electric World Championships held at the Full Throttle Speedway in Kissimmee, Florida. World-class drivers tested the systems at both races and reported their excellent results. Drivers such as Mark Pavadis, Tyree Phillips, Brian Kinwald, and more all used Spektrum modules at these high profile events. But this was just the tip of the iceberg.
