Model aircraft is generally the same as manned aircraft, which is mainly composed of wing, tail, fuselage, landing gear and engine.
1. The wing is the device which can generate lift and keep the lateral stability of the model aircraft in flight.
2、尾翼包括水平尾翼和垂直尾翼两部分。水平尾翼可保持模型飞机飞行时的俯仰安定，垂直尾翼保持模型飞机飞行时 的方向安定。水平尾翼上的升降舵能控制模型飞机的升降， 垂直尾翼上的方向舵可控制模型飞机的飞行方向。
2. The tail consists of horizontal tail and vertical tail. The horizontal tail can maintain the pitch 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 aircraft, and the rudder on the vertical tail can control the flight direction of the model aircraft.
3. The fuselage connects all parts of the model into a whole. The main part is called fuselage. At the same time, the fuselage can be loaded with necessary control parts, equipment and fuel.
4. The landing gear is a device for model aircraft to take off, land and park. One front landing gear and three rear landing gears are called front three-point landing gear; three front landing gears and three rear landing gears are called rear three-point landing gear.
5. The engine is a device that generates flight power for a model aircraft. The commonly used power devices of model aircraft are: rubber band, piston engine, jet engine and motor.
Common terms of aviation model technology
1. The linear distance between the left and right wingtips of a wingspan wing (tail). (the part passing through the fuselage is also included).
2. The straight-line distance from the front end to the end of a full-length model aircraft.
3. The point of resultant force of gravity of each part of the aircraft is called the center of gravity.
4. The cross section shape of an airfoil or tail.
