Looks pretty amazing... dunno if I like the idea of holding a 2.4GHz transmitter that close though.

What is DSM?

DSM is Digital Spectrum Modulation—a purely digital RF link between transmitter and model that is based on Direct Sequencing Spread Spectrum technology. It operates within the ultra-high 2.4GHz worldwide ISM band, provides unequalled signal resolution, and is immune to the most common forms of RF interference. It will even allow your model to “talk” back to you. It requires no crystals and completely frees you from ever having to monitor frequency usage again. Best of all, with Spektrum’s DSM System you can literally plug this phenomenal technology into existing transmitters like the JR R-1 and Airtronics M-8.
