The two pistol grip Spektrum radios have now been upgraded with a more modern look! They still include the same innovative technology that ignited a revolution among all levels of car users, high-end racers, entry level racers and bashers alike. The Spektrum DSM system offers a no-pins, no-interference, no-glitch DSM 2.4GHz technology that has totally revolutionised the way frequency control is viewed. The Spektrum DSM system gives racers an unbreakable digital RF link between transmitter and the car that is based on Direct Sequencing Spread Spectrum technology. Because DSM operates within the ultra-high 2.4GHz ISM band, it is accepted worldwide and is immune to the kinds of RF interference that usually causes glitches found in the 40MHz and 27MHz systems.
This fear of interference being removed has been achieved with the use of the internationally recognised GUID protocol, (Globally Unique Identification Code) that is unique to every individually transmitter, this code proceeds and finishes every packet of signal code that is sent by the transmitter to the receiver.
The system is simplicity itself to use. It is a very easy job to bind the transmitter to the receiver, it’s as simple as pressing buttons and observing the LEDs, switching on the transmitter and receiver in the right order. Once this is done the transmitter will then recognise the receiver every time they are switched on. If you decide to use the receiver with another DSM equipped transmitter - no problem - simply rebind them.
After binding the receiver and transmitter you will not need to worry about clashing frequencies again, as when the system is switched on the transmitter searches the available frequency and grabs the first unused band. It then locks it to your transmitter until you switch off. This means that you do not need to wait at the bottom of the rostrum, if there is a space to drive from simply switch on and drive in the knowledge that no one else can switch onto the frequency you are using.
