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.

The Walkera Chinook is the world’s first RTF (ready-to-fly) tandem rotor semi-scale RC helicopter! Designed to give absolute newcomers and sport pilots the ultimate thrill - never before achievable - in RC model helicopter flight! Up until now, tandem rotor helicopters were considered hugely expensive and difficult to fly - strictly for experts only. The Walkera Chinook is easier to hover than normal helicopters.

Two co-axial rotor systems working together have to be flown to be believed!

The Walkera Chinook Tandem is a 4 channels radio controlled electric helicopter with 2 co-axial systems for outstanding flight stability. It is easy to fly for the beginner, which possesses the characteristics of high sensitivity and full control of the real helicopter. The Chinook Tandem has been designed with an finely-crafted authentic scale appearance with highly detailed fuselage. The undercarriage with retractable style wheel design will add to the enjoyment of flying this superb micro electric helicopter. Finally, 2.4 Gigahertz equipment use less current to operate than standard frequency systems. This results in longer flight time and longer life of your transmitter and receiver batteries!
