Yokosuka K5Y2 Paper ModelThis paper model is a Yokosuka K5Y "Willow", a two-seat unequal-span biplane trainer that served in the Imperial Japanese Navy (IJN) during World War II, created by IPPC. The aircraft was based on the Yokosuka Navy Type 91 Intermediate Trainer, but stability problems led to a redesign by Kawanishi in 1933.

It entered service in 1934 as Navy Type 93 Intermediate Trainer K5Y1 with fixed tail-skid landing gear, and remained in use throughout the war. Floatplane types K5Y2 and K5Y3 were also produced. Below is a type K5Y1:
Yokosuka K5Y1 Paper ModelAfter the initial 60 examples by Kawanishi, production was continued by Watanabe, Mitsubishi, Hitachi, First Naval Air Technical Arsenal, Nakajima, Nippon, and Fuji, for a total of 5,770. These aircraft were the mainstay of Imperial Japanese Navy Air Service's flight training, and as intermediate trainers, they were capable of performing demanding aerobatic maneuvers. Two further land-based versions, the K5Y4 with a 358 kW (480 hp) Amakaze 21A engine and the K5Y5 with a 384 kW (515 hp) Amakaze 15, were projected but never built. [Source: wiki]
