An airplane model is usually an exact copy of an existing aircraft or sometimes it may be a new modern design. Some of these models may be for the show only and not for flight. But others are designed for flight. In some exceptions, the usual form of flight modeling is wireless communication. For these, the controller's radio transmits the signal through its transmitter and the receiver of the plane follows the instructions.
The concept behind a flying plane model is not very different from the original one. Light wood, covering fabric or tissue, is used for body building. Sometimes other substances such as polystyrene are used for such purposes, but wood is the most common choice. For flying an airplane model, an airless atmosphere is especially desirable. The power can be generated from electric power supply. But for the flight plan model, the basic principle behind the original aircraft, gas propulsion or internal combustion engine is used.
The flying of an airplane model by using a wireless remote is a very common day. The remote has different channels for different commands. Mechanical servos refer to the number of channels. The most common channels include Ailerons for roll control, Throttle to control speed, the Elevator for pitch or up and down movement, the Rudder for the left movement movement. Also the flaps can be used to increase the fly lift and groove. As a beginner, a three channel controller is a better choice for flying a plane model. Then the student can switch to a four channel controller. For a complex model, many channels are installed on the controller, for many purposes. For the turn, the helm and back pressure, created by up elevator, are used. In a complex airplane mode design, more options are installed for turning. The communication between the plane and the controller is connected to the frequency. The frequency should be the same for both the transmitter and the receiver. There are several frequencies fixed for airplanes in many countries. For small home toy models with very low frequency band for flying an airplane model.
Before the radio, an airplane model flies by using two wires. One end of the wire is connected to the wings and the other end is at the fingers of the pilot. This type of plane model usually flies in a circle with a pilot in the middle. Some basic laws of physics such as centrifugal force, the straight-hand screw model etc. are used to control the elevator, pitch, etc. The difference in weight and tension of the line between the two ends of the wings is used to maintain the course and control of the plane.
Today, the use of controlled airplanes is usually for the flight of an airplane model, which is available on the child's toy store. Circuit designs of all kinds of models are available for armature designers.
