模型飞机的分类，根据模型飞机操纵形式的不同，通常可将其分为三大类：自由飞类、线操纵类、遥控类。静态飞机模型材质有多种，有金属，塑料，树脂，玻璃钢等，按照比例也分为10多cm，20多cm，30多cm，40多cm，直一米多的模型。国内的有，歼-10飞机模型、歼-15舰载机模型、歼-20飞机模型、歼-11/歼-11B飞机模型等等。动态飞机模型也有多种，主要制作材料为：EPP泡沫、EPO泡沫、KT板材质等。动态飞机模型可以飞行，主要为遥控飞机模型，由人为通过遥控器控制飞行方向和速度。飞行动力一般都是通过电池或者汽油实现
The classification of model aircraft can generally be divided into three categories based on their different control forms: free flight, line control, and remote control. There are many kinds of materials for static Model aircraft, including metal, plastic, resin, glass fiber reinforced plastic, etc., which can be divided into more than 10 cm, more than 20 cm, more than 30 cm, more than 40 cm models up to more than one meter in proportion. There are famous J-10 Model aircraft, J-15 Carrier-based aircraft model, J-20 Model aircraft, J-11/J-11B Model aircraft and so on in China. There are also many kinds of dynamic Model aircraft, mainly made of EPP foam, EPO foam, KT board materials, etc. The dynamic Model aircraft can fly. It is mainly a Radio-controlled aircraft model. The flight direction and speed are controlled manually through the remote controller. Flight power is generally achieved through batteries or gasoline

The main materials of Model aircraft include four major parts (resin, plastic, alloy and new composite materials), with specifications ranging from 40m to 30cm, and the proportion of various models is complete. 1:1 Model aircraft development Co., Ltd. is a manufacturer specializing in manufacturing Model aircraft, and the aircraft model numbers delivered are: passenger aircraft A320, A380, C919, broadcast 737, broadcast 787, flight attendant teaching and training simulation cabin and equipment, aviation simulation cabin, fighter model, helicopter model, The J-10, J-20 Model aircraft, Apache model, air police 200 early warning aircraft, Y8, glider, broadcast 787, Airbus A320 and other aircraft film and television props are produced according to the samples and drawings of customers' different requirements. The products are sold to many domestic and foreign airlines, aircraft manufacturers, science and technology exhibition halls, domestic and foreign gift suppliers, foreign trade companies, etc., and have won unanimous praise for many years. 1. The appearance is prone to yellowing and fading
一个正规的定制军事飞机模型生产厂家，在模型生产中都会选用价钱较贵的涂料，因而生产出来的飞模型即使长时间存放也不容易出现变黄、退色等景象褪色等现象。而小型军事飞机模型厂家生产出来的模型刚开始与大厂家生产出来看起来差别不大，然而半年到一年左右就会逐步变黄、褪色，因此就会有一些厂家把价钱压得更低就有这方面的原因。
A regular manufacturer of customized military Model aircraft will use expensive advanced coatings in model production, so the produced aircraft model is not prone to yellowing, fading and other phenomena even if it is stored for a long time. However, the models produced by small military Model aircraft manufacturers seem to be similar to those produced by large manufacturers at the beginning. However, they will gradually turn yellow and fade from half a year to about a year, which is why some manufacturers will lower their prices.
2、机翼、发起机等部件容易断裂、脱离
2. Components such as wings and initiators are prone to breakage and detachment
一些小的模型生产厂家以及非正规的生产企业受到生产工艺的限制，以及为了节约成本，选用较差的生产材料，更终生产出来模型的机翼、发起机等部件在运输途中十分容易断裂、脱离，特别是量少的情况下，快递运输中这种损失率有时甚于高达70%以上。在互联网上曾经有很多此类模型零售销售商，低价销售这些厂家的产品，然而因为高的运输损失率以及较高的产品瑕疵率，大部分商家在销售一段时间后就会对这一行失去信心而退出或改行。
Some small model manufacturers and informal production enterprises are limited by production processes and choose poor production materials to save costs. The wings, initiators, and other components of the final model are easily broken and detached during transportation, especially in small quantities. This loss rate can sometimes even reach over 70% in express transportation. There have been many retail sellers of this type of model on the internet, selling their products at low prices. However, due to the high transportation loss rate and product defect rate, most merchants lose confidence in this industry after selling for a period of time and withdraw or switch careers.
3、外表不光滑、杂质较多
3. The appearance is not smooth and there are many impurities
正规厂家做得好的军事飞机模型都是采用树脂类生产，很多工序必须要通过手工完成，而一些小厂家一味的为了节省成本，降低，寻求产量，缺少必要的质检工序，成品模型做成以后，或多或少都会有一些存在瑕疵的产品，这十分影响产品的品质。对于模型经销商来说，尽管进货价钱可能相对较低，然而这样高的瑕疵率不仅不能把销售价钱降低，也使得模型销售商处于一种恶性循环当中。
The military Model aircraft well made by regular manufacturers are all made of resins, and many processes must be completed manually. However, some small manufacturers are blindly trying to save costs, reduce prices, and seek output. They lack the necessary quality inspection processes. After the finished models are made, there will be more or less defective products, which will greatly affect the quality of the products. For model dealers, although the purchase price may be relatively low, such a high defect rate not only cannot lower the sales price, but also puts model sellers in a vicious cycle.
