1、外表很容易变黄、褪色

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 legitimate manufacturer of customized military aircraft models will use expensive high-end coatings in model production, so even if stored for a long time, the produced flight models are not prone to yellowing, fading, and other phenomena. The models produced by small military aircraft model manufacturers initially look similar to those produced by large manufacturers, but they gradually turn yellow and fade after about six months to a year. Therefore, some manufacturers may lower their prices for this reason.

2、机翼、发起机等部件容易断裂、脱离

2. Wings, engines, and other components 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，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 inferior production materials to save costs. As a result, the wings, initiators, and other components of the final produced models are prone to breakage and detachment during transportation, especially in small quantities. This loss rate in express delivery transportation can sometimes even reach over 70%. There used to be 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 high product defect rate, most merchants would lose confidence in this industry and withdraw or change careers after selling for a period of time.

3、外表不光滑、杂质较多

3. Unsmooth appearance with a lot of 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 aircraft models made by legitimate manufacturers are all produced using resin, and many processes must be completed manually. However, some small manufacturers blindly seek to save costs, lower prices, and increase production, lacking necessary quality inspection processes. After the finished model is made, there may be more or less defective products, which greatly affects the quality of the product. For model dealers, although the purchase price may be relatively low, such a high defect rate not only fails to lower the sales price, but also puts model sellers in a vicious cycle.
