In addition to unparalleled freedom and interference protection, 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.
