As promised, here is a short summary of the description in the book:
The plane was originally a civil project for an attempt to break the world speed record and was taken over by the Imperial Japanese Army under the designation Ki-78.
To minimize drag, the fuselage had a minimum cross section and the wings had laminar airflow. To reduce landing speed, the rather small wing had combination of Fowler and split flaps as well as drooping ailerons. The Db 601 A was modified to incorporate a water-methanol-injection – the first time in Japan – to boost the power to 1550 hp for a short time.
First flight was on 26 Dec. 1942, the plane was extremely difficult to fly at low speeds and had high take off and landing speeds. On its 31st flight, the plane reached its maximum speed of 699.6 km/h at 3527 m, which was considerably less than the aimed goal of 850 km/h.
Flight trials were suspended after the 32nd flight on 11 Jan. 1944 because too many airframe and engine modifications would have been required to achieve the calculated performance.
Best wishes
