The R/C model is an advanced industrial product.
While I can better understand what goes into an R/C model when I build it myself, I can also appreciate how many components are used. There are many materials used within the components to bring the final product together. While these can be generally categorized into either metal or resin parts, they can be broken down even further. For example, metal parts can be categorized into iron / aluminum alloy / stainless steel / titanium while resin parts can be categorized into carbon / FRP / polycarbonate / ABS/ and nylon, among others. Some people still perceive R/C models as toys yet R/C models incorporate high grade industrial materials used in the automotive industry such as carbon materials, aluminum alloys and titanium. Our desire is to have R/C models appreciated as industrial level products in the same way cars are and not as ‘toys’. Furthermore, there are many grades for aluminum alloys such as ‘2017’, ‘5052’, ‘6061’, ‘6063’ and ‘7075’ which have different mechanical properties and features. R/C model developers carefully examine the advantages and characteristics of various materials and grades as mentioned above and select the appropriate material for their role inside the model. This creates the optimal combination of high performance and high quality for the best user experience.
