According the Changhe Aircraft Industries Corporation website, it is claimed to be the first indigenously-designed helicopter in China. It is based off the Eurocopter Ecureuil however.[1] The Z-11 project started in 1989 and the first flight was made in Dec 1994. In Oct 2000, test flights of Z-11 were completed. The general designer of Z-11 is Mr. Wu Ximing (吴希明), who is also the general designer of three other Chinese helicopters, including WZ-10. Under Mr. Wu, Z-11 became the first Chinese helicopter to be completely designed by CAD/CAM.[2]
