In the past we had radio control systems that worked using AM (Amplitude Modulation), then FM (Frequency Modulation), followed by PCM (Pulse Code Modulation) and now, and for the future DSM (Digital Spectrum Modulation) It has often been said in the past that you can’t make a better mouse trap. Well that may be true but you can certainly make a better radio system, and that’s exactly what the technicians at Spektrum have done! Next generation technology for the next generation of model flyers; that’s the Spektrum system!
