In order to verify the durability of ABS die-cast alloy metal in long-term use, it is necessary to conduct weather experiments on it; by simulating the use under extreme climate conditions, it is ensured that the metal can still maintain its original mechanical strength and durability after aging. Die-cast metal aircraft with plastic parts, no assembly required, in order to improve the aesthetics and functionality of the ABS fairing, surface treatment is required; including grinding, sandblasting, spraying primer, topcoat and other steps; these treatments not only beautify the appearance of the model, but also improve its weather resistance and scratch resistance. It can reflect the manufacturing technology of the time. From the early simple wooden structure to the current application of high-tech materials such as composite materials and carbon fiber, the development of model aircraft is also a microcosm of the progress of material science and manufacturing technology. Collecting this model aircraft can intuitively see the evolution of these technologies. Model airplanes can serve as physical witnesses of aviation history. The design of early model airplanes reflects people’s understanding of real airplanes and their spirit of exploration of flight at that time. Models carry the memory of early aviation and have irreplaceable value in studying the evolution of aviation technology from scratch.
