The NewRay Pilot model kits are model kits that do not need glue. The kits are different from the typical model kits with runners where one would cut away the parts and glue them together. These models come as disassembled toys/models. The major assemblies are kept together by screws; usually 4 to 6 are enough. Some minor parts such as the vertical stabilizer (vertical fin) are snap fit. They are pre-painted so they are ready to be displayed or played with right after assembly, which would usually take about 5 to 7 minutes. However, with a little bit of paint/permanent marker, one can greatly enhance the look of these models. All in all it would be a great gift to an 8 year old or a "low cost practice platform" for model builders trying to improve their painting/weathering/detailing techniques.
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The commission approached NAA to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, NAA proposed the design and production of a more modern fighter. The prototype NA-73X airframe was completed on 9 September 1940, 102 days after contract signing, achieving its first flight on 26 October.
