The Air Hogs apache helicopter is issued under license with Boeing. However the unit comes complete and there is no assembly required. The heli is suitable fro 8 years old and it is advised top fly it indoors only.The control has a 4 way unit and you can fly easily for at least 8 minutes. Thoughtfully the makers proved batteries fro the heli itself, but you will need to buy separate batteries fro the transmitter.



The controlling transmitter not only charges the helicopter but also controls it in flight. An indication that the heli needs recharged is if flight time reduces. Great thing having rechargeable batteries, otherwise it would cost a fortune. To stop the heli from spinning press and release the trim control.

At the begging of the 21st century a new transmission wavelength was used for radio control in toys. This had the advantage of allowing smaller aerials and far less power consumption. Waht you do need to be carful about though. is that the line of site between your transmitter and the heli is always maintained. Otherwise the unit needs to reboot and this could be in the middle of a flight..not too good and idea.

Radio Control electronics have three essential elements. The transmitter is the controller. Transmitters have control sticks, triggers, switches, and dials at the user's finger tips. The receiver is mounted in the model. It receives and processes the signal from the transmitter, translating it into signals that are sent to the servos. The number of servos in a model determines the number of channels the radio must provide.

Today speed controllers are taking the place of the older inefficient resistors.These units are totally electronic with no moving parts and therefore less to breakdown.Futaba of Japan was the first company to bring steering control to the market.The unit here has a trigger control for the throttle and a wheel for steering the car.

All types of toys now enjoy this new technology and children can play with cars or helicopters and use the new devices very safely. Hobby people can buy units that allow modular upgrading to give them more control and features of their units.

Modular addons allow equipment from different makers to be added.You can now take equipment from ,say,a car and add it to a boat. But you will find a legal restriction because different frequency bands have different laws applying to them.

Most manufacturers now offer "frequency modules" (known as crystals) that simply plug into the back of their transmitters, allowing one to change frequencies, and even bands, at will. Some of these modules are capable of "synthesizing" many different channels within their assigned band.
