Radio control units that are available today come in many varieties and brands that can be broken down into three types: The only problem with this technique is that you need two transmitters of the same type as different brands or types of radio transmitters often cannotДЄlso, there is a method of using different transmitters to wirelessly connect them together: 'Wireless Buddy Box' where this can be connected If the plane 'gets into trouble', the person helping teach the beginning pilot just releases the switch on the main transmitter and regains control of the plane without incident. This capability is sometimes known as a trainer or 'buddy box'.ДЄ cable connects two transmitters of the same brand and pressing a switch on the main transmitter, allows the other control over the plane. Some radios have the additional capability of connecting one radio transmitter to another to help This means that as long as you can see your plane, you still should be able to control it. Most better radio systems have at a range of at least a half mile or more (in the air). There are also a completely different class of radios used for carsДЄnd boats known as 'Pistol Grips', but they also operate in the same basic manner. There are 4, 6, 7, 8, 9-channel transmitters (and receivers), up to about 14 channels in expensive systems. I really wouldn't recommend buying one of these style radio transmitters as I think it will frustrate you. These are also known as '2-Stick Transmitters' and are is NOT the preferable configurationДЇor most pilots and it can be difficult to find a fellow pilot who will (or even can) fly with this setup. The lever (or stick) on the right only moves right and left and is used typically for rudder only. There are still brands of radios that are advertised as 2-channel units, have 2 control levers,Д«ut the lever on the left only moves up and down and is for is for elevator (up and down) control only. Many of these radios also can come with internal electronic servo mixing options, useful on V-Tail and Elevons. Most 4-channel radios come complete with nickel-cadmium or other type of rechargeable battery packs that are reliable and can give many years of service. Novice or beginner sailplanes usually need only 2 channels of control,Д«ut you are still better off purchasing a radio with at least 4 channels of control. Typically, a radio system package comes with just about everything you need So, when you move the 'rudder stick' on the transmitter, the rudder moves on the model, and so one for each of the transmitter controls. You connect the servos to different control surfaces on the plane such as the

Those motors are known as servos and rotate (or move) as the control levers on the transmitter are moved. Translated them into movement of motors on board the plane.

In either case, once the receiver, either traditional or spread-spectrum receives the signal from the transmitter, this is To a receiver by sending a specific sequence of these radio waves so that no other receivers can detect meaningful data. Now we have spread-spectrum transmitters that 'match' a particular transmitter Was tuned to listen to just that frequency.

The transmitter is what you hold in your hand and the receiver is what you put in the plane.ДЇor many years, transmitters sent signals out on one specific frequency and the receiver In radio controls used in modelling, there are two basic components: a transmitter and The only real difference is the frequency at which they operate and the technique used to transmit those radio waves.ДЄlso contained within that radio wave are a set of individual 'channels' that allow multiple signals to be sent with one radio frequency. These systems modulate and transmit radio waves similar to the radio waves your AM or FM radio in your car or home receives. Radio Control or R/C is just the name of a system that uses various radio waves to control some sort of device.
