一、比例不正规

1、 Irregular proportion

因为非正规厂家生产的模型产品未经航空公司、飞机制作厂授权，而是通过伪造正规厂家产品，或许通过互联网上搜集的一些飞机图片生产而成，因而模型的仿真程度相对较差、比例失调。正规厂家则是依据航空公司、飞机制作厂所供给图纸生产模型。

Because the model products produced by informal manufacturers are not authorized by airlines and aircraft manufacturers, but are produced by forging the products of formal manufacturers, perhaps through some aircraft pictures collected on the Internet, the simulation degree of models is relatively poor and the scale is out of proportion. Legitimate manufacturers produce models based on the drawings provided by airlines and aircraft manufacturers.

二、模型工艺差

2、 Poor model process

外表容易黄、褪色

The appearance is prone to yellowing and fading

正规生产厂家为 产品的品质，在模型生产中所选用的都是价钱较贵的高等涂料，因而这种模型即便长时间存放也不容易涌现变黄、褪色等景象；而小企业以及非正规企业为了降低生产本钱则选用价钱低廉的涂料，这种涂料生产出来的模型刚开始与大厂家生产出来基础无异，然而短则半年长则一年就会逐步涌现变黄、褪色的状况，这也是为什么一些厂家能把价钱压得更低的原因之一。

Regular manufacturers use expensive and high-quality coatings in model production to ensure product quality. Therefore, even if stored for a long time, this type of model is not prone to yellowing, fading, and other phenomena; Small businesses and informal enterprises, in order to reduce production costs, choose low-cost coatings. The models produced by these coatings are initially similar to those produced by large manufacturers, but in the short term, they will gradually turn yellow and fade in a year. This is also one of the reasons why some manufacturers can lower their prices.

机翼、发起机等部件容易断裂、脱离

Wings, engines, and other components are prone to breakage and detachment

小模型生产企业机非正规范围型生产工艺的限制，以及为勤俭本钱而选用较差的材料的原因，他们所产生出来模型的机翼，发起机等部件咋运输途中十分容易断裂、脱离。这种损失率在成批的货物运输中可能相对较小，然而关于少量货物的快递运输中这种损失率有时甚于高达百分之七十以上。

The limitations of non-standard production processes in small model manufacturing enterprises, as well as the use of inferior materials for frugality, make it easy for the wings, engines, and other components of the models they produce to break and detach during transportation. This loss rate may be relatively small in bulk transportation of goods, but in express delivery transportation of small quantities of goods, this loss rate can sometimes even reach over 70%.

在互联网上网站曾今涌现过为数众多的此类模型零售销售商，并低价销售这些厂家的产品，然而因为高的运输损失率以及前文所说的高的产品瑕疵率，大部分商家在销售一段时间就纷繁关门或改行。

A large number of such model retailers have appeared on Internet websites and sold their products at low prices. However, due to the high rate of transportation losses and the high rate of product defects mentioned above, most of them have closed their doors or changed their business lines in a long period of time.

外表不光滑、杂质较多

Unsmooth appearance with a lot of impurities

树脂类飞机模型因为很多工序要通过手工完成，而一些厂家一味的寻求产量，降低本钱和产品价钱，这些模型往往缺少必要的质检工序，成品模型中都会有一些存在瑕疵的产品混在当中。

Resin based aircraft models often lack necessary quality inspection procedures due to the manual completion of many processes, and some manufacturers blindly seek output, reduce costs, and product prices. The finished models often contain defective products mixed in.
