Version planeur à échelle réduite (1/1,666) de l'avion de transport Hitachi HT-3F, construit par Fukudu Kei Hikoki Seisakusho (Fukudu light Aeroplane Manufacturing Works)
This aeroplane was a 60 percent scaled-down version of the Hitachi HT-3F Medium Passenger Transport that was to be flown as a towed research glider. It was manufactured by Fukuda at the request of the Aviation Bureau that sponsored the development of a domestic service type transport. It was felt that better performance data could be acquired from this glider version than from a wind-tunnel model. The wing aspect ratio was 8.78. As a glider, it had simulated engine nacelles as well as having the undercarriage in the retracted position. It was at this time, however, that priority was directed to military aircraft, causing the HT-3 to be terminated at the mock-up stage.
