RS Models 92103 Tachikawa Ki-106

The Tachikawa Ki-106 is a Japanese low-wing prototype fighter from the end of World War II. The prototype flight took place in 1945, but the machine never entered mass production. The machine was 9.95 m long with a wingspan of 11.24 m. The drive was provided by a single Nakajima Ha-45-21 engine with a maximum power of up to 1990 HP. The on-board armament consisted of two or four 20 mm cannons.

The Ki-106 aircraft was developed at the Tachikawa plant as a peculiar development of the very successful Nakajima Ki-84 fighter machine. In its construction, almost exclusively wood and canvas were used as substitutes for the increasingly scarce aluminum, which was definitely lacking in the Japanese economy at the end of World War II. Moreover, the production process was also simplified, which would allow employing low-skilled workers in its production. Unfortunately for the Japanese military aviation, the Ki-106 turned out to be heavier than the Ki-84, which worsened its performance, and what's more - the durability of the entire structure dropped significantly. In total, only three prototypes of the Tachikawa Ki-106 aircraft were built.
