按飞行方式分类：
Classification by flight mode:
固定翼模型类、直升机模型类、飞艇类 、火箭模型类 ；
Fixed wing model, helicopter model, airship model and rocket model;
按竞赛项目通用划分
General division by competition item
根据模型飞机操纵形式的不同通常分为四大类：
According to the different control forms of model aircraft, it is usually divided into four categories:
F1自由飞类、F2线操纵类、F3遥控类、F4象真类；
F1 free flight, F2 line control, F3 remote control and F4 image reality;
F1自由飞类
F1 free flying class
F1A牵引模型滑翔机
F1A traction model glider
F1A需要利用人力或机械牵引装置牵引升空，当爬升到适当高度时，牵引线脱钩，模型飞机开始自由滑翔；留空时间长短决定胜负；
F1A needs to be towed and lifted off by manual or mechanical traction device. When climbing to an appropriate height, the traction line is decoupled and the model aircraft begins to glide freely; The length of time left blank determines the outcome;
F1B橡筋动力模型滑翔机
F1B rubber powered model glider
橡皮筋驱动螺旋桨来产生拉力起飞，升空后自由滑翔；
The rubber band drives the propeller to generate tension to take off and glide freely after taking off;
F1C活塞式发动机滑翔机
F1C piston engine glider
以活塞式发动机为动力驱动螺旋桨起飞；
Take off with propeller driven by piston engine;
F1D室内模型飞机
F1D indoor model aircraft
像筋螺旋桨做动力在封闭的室内空间飞行；
Like a rib propeller to do power in a closed indoor space flight;
F2线操纵类
F2 line manipulation class
F2A线操纵竞速模型飞机
F2a line operated racing model aircraft
以操纵者为轴心，内燃机发动机或电动机做动力，通过操纵线控制飞机的升降舵操纵与控制，在一个圆形的空间内飞行。以飞行圈数和短时间者为胜；
With the operator as the axis and the internal combustion engine or motor as the power, the elevator control and control of the aircraft are controlled through the longitudinal line to fly in a circular space. Take the number of flight laps and short time as the winner;
F2B线操纵特技模型飞机
F2b line control stunt model aircraft
这种模型飞机可由操控者控制，按要求做出各种特技动作，如筋斗、倒飞等，裁判根据动作完成质量打分，评出胜负；
This model aircraft can be controlled by the operator and make various stunts as required, such as somersault, inverted flight, etc. the referee will score according to the completion quality of the action and decide the victory or defeat;
F2C线操纵小组竞速模型飞机
F2C line control team racing model aircraft
由三架模型飞机同时上场飞行，飞完规定的圈数后，以总飞行速度确定成绩；
Three model aircraft will fly at the same time. After completing the specified number of laps, the result will be determined by the total flight speed;
F2D线操纵空战模型飞机
F2D line operated air combat model aircraft
两架模型同时在场上飞行，用螺旋桨去“咬”对方模型的彩带，“咬”的次数越多，得分越高；
Two models fly on the field at the same time. Use the propeller to "bite" the ribbon of the other model. The more times you bite, the higher the score;
F3无线电遥控类
F3 radio remote control
F3A无线电遥控特技模型飞机
F3A radio remote control stunt model aircraft
通过设计制作航空模型，采用无线电遥控的方式，留空做出各种规定的特技动作；
First, through the design and production of aviation model, using the way of radio remote control, leaving space to make various specified stunts;
F3B无线电遥控模型滑翔机
F3B radio controlled model glider
类似于F1A没有飞行动力，需要牵引升空后滑翔飞行，主要竞赛留空时间、定点降落和飞行速度；
Similar to F1A, it has no flight power and needs to glide after taking off. It mainly focuses on the blank time, fixed-point landing and flight speed;
F3C无线电遥控模型直升机
F3C radio remote control model helicopter
特技飞行动作为主，特点是遥控直升机结构复杂，操作困难，很有挑战性；
Stunt flight is mainly used, which is characterized by complex structure and difficult operation of remote-controlled helicopter, which is very challenging;
F3D无线电遥控竞速绕标模型飞机
F3D radio remote control race around bid model aircraft
比赛中多架遥控飞机同时起飞，按照固定的几个折返标志点绕标飞行，飞行速度快者胜出；
In the competition, multiple remote-controlled aircraft take off at the same time and fly around the mark according to several fixed turn back signs. The one with fast flight speed wins;
F4仿真模型类
F4 simulation model class
以真实的飞机作为参考，缩小比例制作的飞机；
Take the real aircraft as a reference and reduce the scale of the aircraft;
Large space model http://www.quanyimoxing.com Focus on providing services for you. Please remember to pay attention to us for more wonderful contents. We sincerely provide services for you
