RC Channels

After you have built a plane, you need to use a transmitter and a receiver depending on the number of channels in your plane, but in fact it may not seem easy. Rather, the device should be selected and the aircraft designed in a harmonious manner so that all components work in the best image and accuracy in flight. The planes differ in a way that connects them with the transmitter and the receiver according to the three ways of movement of the aircraft. You know that each type of horizontal plane, helicopter and drone have a different dynamic and also a different connection method. We will study  remote controls and their different characteristics.

  • Transmitter

It is important to understand the basics of radio control equipment, and how it works to make your RC plane do what you want (most times!), Is important if you want to get the most out of your new hobby. The basic components of a typical radio control system are the transmitter, receiver and servo motor. Battery packs or cells are needed to operate all components. However, modern electric power (EP) receivers do not usually have their own battery because their power is taken directly from the motor’s battery pack. Only, or even the transmitter alone, without any devices. This is simply because the type and size of the components are much different these days, because their applications are more diverse than ever before – it will be difficult for the manufacturer to know what kind of motors and others, so it is better to leave a choice up to the pilot!

Also, many commercially produced aircraft (such as RTF, BNF and PNP models) come with a receiver that you can configure with different transmitters. A single-channel RC plane has only one function that can be controlled by the pilot, for example rudder movement or on / off electric motor. Two channels can be rudder and motor while 3 channels can be motor, rudder and elevator or motor, rudder and ailerons.

A typical 4-channel RC aircraft will have the rudder, elevator, throttle and ailerons, the four basic controls in a remote control aircraft. Some devices may have up to 18 channels, but this will cost you a four-digit number. There are no strict and quick rules as to how many channels a RC aircraft can have, it depends solely on the aircraft itself and / or how many functions the pilot wants to control. More complex remote control aircraft may require 6, 7, or 8 channels or more to operate basic controls as well as any additional functions such as retractable landing gear, flap panels, landing lights and camera operation.

  • Receiver

If you are a beginner, do not buy the Transmitter and receiver separately. You do not need some special settings. The receiver is located inside the aircraft and connected directly to all devices (electronic speed control ESC – in electric aircraft), by special wires. The thin wire antenna extends to several inches and must be installed, full length, and slightly outward from the aircraft. Some receivers contain one or two much smaller antennas, no longer than one inch or so. The long antenna of the MHz receiver should never be cut or disassembled to reduce its length. By doing this, RX’s ability to receive the radio signal from the TX is greatly reduced and this usually has serious consequences. The aircraft will fly very quickly outside the radio range, and you will lose full control. As soon as a plane crash or lost is inevitable!

In the same way that a conventional radio or TV receives the signal from the broadcasting station, the RX radio controller receives the signal emitted from the transmitter when you move a stick or click the switch. These signals are then passed to the parts, or ESC, which respond appropriately. The number of slots on the receiver depends on the number of channels, that is, the 5-channel RX channel has six slots – one per channel plus one for the battery pack connection. The future will be more complex means more openings. Now go to a store and buy all the pieces according to your study and installed in the right way and enjoy flying high, the more channels the more fun and the possibility of adding more control features and sensors and improvements, but perhaps the transmitters with LCD screens are relatively expensive.
