RC flying is one of the most exciting and popular sports all over the world. The wide ranges of RC planes for the beginners as well as advanced fliers are available in the market. Choosing your first ever RC plane is a very exciting process for anyone. There is no prescribed theory of buying an RC plane. Any model of RC airplane which is simple, stable, durable and relatively slow while flying will certainly be the perfect any beginner to this flying hobby.
This article is will provide you the basic information related to the functioning of your Radio controlled aircraft both electric as well as gas powered. This article will help you to know what does your remote controlled aircraft contains and how you can choose the best aircraft for you. This will help the beginner flier to understand basic of its technical construction as well as the functions of its various components.
Let’s understand hereby the common as well as important components of different types of Radio controlled aircraft and their functioning.
- Radio transmitter and the receiver:
This is a common component of all radio controlled aircraft. But functioning may vary depending upon the channels your device has. Most of the RC aircraft have 4 channels. Sailplanes may have two or three channels.
There are 1 to 6 channel transmitters available. Channels indicate the things you can control. A standard RC transmitter that one can buy for an RC plane has 6 channels. These channels control the motor, Aux 1, Aux 2, rudder, elevator and ailerons. So technically speaking each channel controls a different motor.
Most of the new radios do not require you to change crystals; they “bind” to the receivers and use the transmitter and receiver. The majority of the new radios do not require you to change crystals, they “bind” to the receivers and use 2.4 GHz radio frequency which is a much higher radio frequency.
The receiver normally runs off of 5 volts and it sends signals to the servos to turn the RC plane. A receiver also sends signals to the ESC regarding the speed of the motor it should run. The receiver gets volts from the battery elimination circuit or ESC’s BEC.
This is a strong geared electric motor which enables the flaps, rudder, and throttle to work. Servos come in different sizes and the torque generated by the servos totally depends upon the size of the servos. They are plugged into the receiver through three conductor wire.
They work in proportion, i.e. if you move the control stick just a fraction of an inch the control surface will also in the same proportion.
The direction which you move through the control sticks needs to be the same for all RC flying aircraft. There are mainly 4 controls through throttle, Elevators, aileron and rudder.
Throttle controls the speed of the engine of the RC plane and thus how slow or fast the propeller rotates. Many basic electric RC planes may not have a throttle; they may have just on/off switch instead. The elevators control the horizontal pitch of the RC airplane.
The elevators are the attached section of the horizontal stabilizer at the rear and they are the only major control surface. Changing the degree of angle of these elevators controls the upward and downward movement of the plane.
The ailerons control the roll of RC plane. Ailerons work through the change the volume of lift generation over the wings of the plane. It is not necessary that all RC planes have ailerons. Ailerons are mainly used in all aerobatic drills that require a rolling motion. The rudder turns the plane to the right or left. It is the hinged section of the vertical stabilizer that is fin at the rear.
- Control rods:
Control rods expand to the movable parts of the aircraft like the rudder, ailerons, and elevators. The movement of these rods moves the controlled parts of the plane and enables it to change its flight path.
- Power supply / Battery:
The light weight of your RC device will provide better flight time and performance. Lithium polymer or Li-Po batteries are the latest types of batteries which are light in weight then Ni-cad and NiMH batteries. The majority of RC aircraft use these Li-Po batteries. You need to charge this battery with a balanced charger which can charge all the cells to a required voltage. Through high current capacity and low weight, these batteries are the first choice for any RC device.
Nitro or Gas powered RC airplane works same as real airplanes burn fuel and so do these. Two cycle high RPM engines are mostly used in RC aircraft and supply an adequate power to get the job done twice. This fuel has a nitro-methane alcohol and the oil mixture that lubricates these engines as they run.
These engines are also called glow engines as they have a small glow plug to keep the spark for ignition. You can simply use any battery to heat up it and start the engine.
There are also Gasoline burning and 4 stroke engines and they also make a use of same fuel. They have valves same as any car engine has. This engine provides more torque for bigger propellers and better fuel economy these are the biggest advantage of 4 stroke engine. To start, you need to attach the glow starter, and turning the engine over using the starter motor.
These involve assembling of all the parts of your RC planes. There are number almost ready to fly (ARF) powerplants available in the market. You must be aware of the fact that these ARFs still requires assembling process of hours. In case you have a shortage of time you can go for ARF powerplant.
Here you also have to be careful about your budget as these ARFs are charged a little bit high. The range of ARFs start from $200 and it goes up depending upon the extra features, power supply etc.
I hope this article will help you to know your Radio control airplane in a better technical ways. While buying a new RC airplane you can go through the details of the parts, their capacity and accordingly pick the best RC airplane for you.
