Engineering:Sunward UAV

From HandWiki

Sunward UAVs are Chinese UAVs developed by Hunan Sunward Co Ltd, (Sunward, 湖南山河科技有限公司), a firm formed in February 2008 by a professor of Tsinghua University as a subsidiary of Sunward Intelligent Equipment Group (山河装备集团) to concentrate on aviation products. Sunward that not only produces UAVs of its own design, but also produce light sport aircraft such as the two-seater Sunward Aurora SA60L and flying boat Ramphos Trident for other firms as their original equipment manufacturer.

SVU-200

SVU-200 Flying Tiger (Fei-Hu or Feihu, 飞虎) is an unmanned helicopter developed by Sunward. The general designer of SVU-200 Flying Tiger is Mr. Dennis Fetters, the founder of Revolution Helicopter Corporation and later Fetters Aerospace LLC after coming out his retirement.[5] SVU-200 Flying Tiger is an upgrade of Star-Lite unmanned helicopter developed by Dennis Fetters and his Fetters Aerospace LLC with various minor improvements and as a result,[6] the two unmanned helicopters look very similar externally, with only minor difference. For example, Fetters Star-Lite lacks the horizontal stabilizer above the tail rotor that is present on SVU-200. Although living in Changsha and working with Sunward for more than two years, Dennis Fetters did not stay with Sunward afterward, but instead, relocated to Wuhan to become chief technology officer of Ewatt Aerospace, another Chinese UAV manufacture, he and his Fetters Aerospace LLC still provide certain degrees of support of SVU-200 program.
