Aware of its aging fighter aircraft fleet, in 1927 Imperial Japanese Army asked Kawasaki, Nakajima and Mitsubishi to study a new fighter aircraft design. Mitsubishi team led by Nobushiro Nakata assisted by Jiro Tanaka and Jiro Horikoshi (who then in turn design A6M Zero) conceived a parasol aircraft powered by 600hp Mitsubishi Hispano-Suiza water-cooled V-12 engine, built around a metal frame covered in fabric while the wings was made of wood, the first prototype was completed in May 1928 with top speed of 196mph, the fastest of all design submission. Unfortunately the prototype fell apart in flight.
This is an other papermodel design from Argwenza Kainaka, he only specify it as a non-scale model, but by calculating its wingspan, i guess it is around 1/60 scale, the pdf file contains the model pattern and its instruction manual.
Designer note: "This model is actually a simple model. I'm so sorry for an inaccurate, or missing details."
