模型飞机一般与载人的飞机一样，主要由机翼尾翼机身起落架和发动机五部分组成。

Model aircraft, like manned aircraft, are mainly composed of five parts: wings, tail wings, fuselage, landing gear, and engine.

机翼———是模型飞机在飞行时产生升力的装置，并能保持模型飞机飞行时的横侧安定。

Wings - are devices that generate lift during flight and maintain lateral stability of the model aircraft.

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。

Tail wing - includes two parts: horizontal tail wing and vertical tail wing. The horizontal tail maintains the pitch stability of the model aircraft during flight, while the vertical tail maintains the directional stability of the model aircraft during flight. The elevator on the horizontal tail can control the lifting of the model aircraft, while the rudder on the vertical tail can control the flight direction of the model aircraft.

机身———将模型的各部分联结成一个整体的主干部分叫机身。同时机身内可以装载必要的控制机件，设备和燃料等。

The main body, which connects the various 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.

起落架———供模型飞机起飞着陆和停放的装置。前部一个起落架，后面两面三个起落架叫前三点式；前部两面三个起落架，后面一个起落架叫后三点式。

Landing gear - a device used for takeoff, landing, and parking of model aircraft. One landing gear in the front and three landing gears on both sides in the back are called front three-point landing gear; There are three landing gears on both sides of the front, and the rear landing gear is called the rear three-point type.

发动机———它是模型飞机产生飞行动力的装置。模型飞机常用的动装置有：橡筋束活塞式发动机喷气式发动机电动机。

Engine - It is a device that generates flight power for a model aircraft. The commonly used propulsion systems for model aircraft include rubber band piston engines, jet engines, and electric motors.
