While the DX3R’s intelligently designed ergonomics are easily recognizable, it is the superior responsiveness of its advanced 2.4GHz DSM2 technology that will get people talking. In addition to unparalleled freedom and interference protection, patent pending DSM2 has a faster response time than any other spread spectrum or PPM system. With it, you will be able to hold the line around a track with a level of precision and control unlike anything you have experienced before. And because DSM2 uses direct sequence spread spectrum technology, you’ll maintain this superior response rate no matter how “noisy” the 2.4GHz environment gets.
