01/31/2008. Remarks by Johan Visschedijk: "Prototype of the Yunshuji-11 (Y-11, Transport-11) was first flown on December 30, 1975. Powered by two 285 hp Quzhou Huosai-6A nine-cylinder radial engines, it had a crew of two and could accommodate seven passengers normally, with a removable jump-seat for an eighth passenger. In the cargo configuration it could haul 1,918 lb (870 kg). The first fifteen of the forty produced were used as crop-dusters."
