The high-quality 2.4GHz electric-powered helicopter comes with high speed and
low speed controller that is perfect for the beginner to learn to fly, or for
the more experienced pilot to simply have fun.This model has LED night light to
adapt to night flying.The model is powered by the latest technology high power
lithium polymer battery (7.4v 800mAh)!The flying time is about 7 minutes and Charge
time is approximately 2.5 hour.
The transmitter is supplied with 8 x 1.5v dry cell batteries to get you flying.
When the battery voltage is low, a low voltage alarm (three lamp flash). With LED
lights indicate power output size
WHAT IS 2.4GHZ TECHNOLOGY
Operating at 2.4GHz puts the radio control out of the frequency range of
any \"noise\" caused by the other electronic components - such as the motor,
speed controller and any metal to metal noise - eliminating interference and
glitching that can affect a 35mhz system. Obviously, the last thing you need
when piloting an RC helicopter is anything that might cause loss of control or
a crash (you may not be aware if your neighbour is also flying on the same frequency
as you in his back garden, for example). The built-in security of the 2.4G system
allows you to maintain radio control at all times, ensuring your safety and that of
others around you. Instead of transmitting on one channel at a time, both the transmitter
and receiver are constantly hopping from channel to channel - at over 1000 times a second!
When you initialy \"pair\" your transmitter to your receiver, they initiate the synchronised
sequence of channel hopping.With 2.4GHz effectively 40 channels are available and the sets
automatically set themselves to an unused frequency when switched on. Operation is constantly
self monitored and the set will move to an unused frequency if any interference is detected.
Because 2.4G RC systems work on higher frequency short wave length,the transmitter antenna is
only about 15cm long and flexible - avoiding bends and breakages that can occur with traditional
35Mhz telescopic aerials! The receiver antenna is much shorter too - allowing for much neater
installation of the radio gear in the helicopter.
ADVANTAGES OF 2.4GHz
(1).Traditional 35MHz remote controls require a transmitter with 750mW transmitting power consumption
but 2.4G transmitter only needs 4mW power consumption so batteries last much longer
(2)2.4GHz frequency band completely eliminates frequency interfering when flying so no more potential
crashed due to radio glitches or interference.
(3)2.4GHz remote control systems automatically bind frequency using a microprocessor and constantly
change so no more need for crystals and more importantly no chance of someone switchiing on there
transmitter with the same crystal as you, causing your heli to crash.
(4).Dual transmission gives better response and control of you heli and reduces servo quiver.
(5).2.4Ghz System frequency wave range is 1/4 of the usual used frequency wave range so the
transmitter antenna is just 14.5cm in length making flying indoors much easier.
