09/30/2016. Remarks by Johan Visschedijk: "Designed by the Harbin Aircraft Factory at Harbin, China, the Model 701 three-seat light utility helicopter was unmistakably based on the Bell Model 47G. Main external differences were the cockpit with much less glazing area and the cylindrical fuel tanks. The main difference was the powerplant, a vertical-mounted 260 hp Zhuzhou HS-6C nine-cylinder radial engine (license-built Ivchenko AI-14R).
Design of the Model 701 started in 1965 and the first flight was made on January 23, 1970. Although intended to be use in many military and civil roles, only a few were produced by the Weidong Machinery Factory at Jinan. Two aircraft are preserved, one at the Nanjing University of Aeronautics and Astronautics at Nanjing, and the pictured one at the People's Liberation Army Air Force Museum at Datanshang."
