New 2.4G Spread Spectrum technology allows the transmitter and receiver to be 'locked-on' to the same frequency ensuring much improved reliability and peace of mind when flying. Second, 2.4 Gigahertz systems offers quicker, more responsive control, when compared to a standard frequency system. Third, Operating at 2.4 Gigahertz also puts the radio control out of the frequency range of any 'noise' caused by the other electronic components on your helicopter - such as the motor, speed controller and any metal to metal noise - eliminating interference and glitching that can affect traditional frequency system. Fourth, another main characteristic of 2.4 Gigahertz equipment from a RC model club’s point of view is that no frequency control is needed. Eliminating the need to check everyone else's channel numbers, prior to flying. No more worries about turning up at a club with the wrong crystal in your Tx.
