F3C is the standardization of flight.

A model airplane, like a manned airplane, mainly consists of six parts: wing, tail, fuselage, landing gear, engine and control system.

1, wing-a device that generates lift when a model airplane flies, and can maintain the lateral stability of the model airplane when it flies.

2. Tail-including horizontal tail and vertical tail. The horizontal tail can maintain the pitching stability of the model aircraft, while the vertical tail can maintain the directional stability of the model aircraft. The elevator on the horizontal tail can control the lift of the model plane, and the rudder on the vertical tail can control the flight direction of the model plane.

3. fuselage-the trunk part that connects all parts of the model into a whole is called the fuselage. At the same time, the fuselage can be loaded with necessary control components, equipment and fuel.

4. Landing gear-the device for taking off, landing and parking of model aircraft. There is one landing gear in front and two landing gears in the back, which are called front three-point landing gear, front landing gear and rear landing gear.

5. Engine-It is the device for generating flight power for model aircraft. The power devices commonly used in airplane models are rubber bands, piston engines, jet engines and motors. Less commonly used are: pulse jet engine (heavy weight, high fuel consumption), rotary engine (only one kind of OS), air engine (similar to piston engine used in indoor model in 1970s).

6. Control system-The control system is mainly used to control the air maneuver of the model, including takeoff, landing and steering.
