Airkraft Sunny
The Airkraft Sunny is an ultralight aircraft that was designed by Dieter Schulz. The aircraft was initially produced by his company, Tandem Aircraft KG of Saulgau, Germany, which built about 150 examples between 1989 and 1999. After he sold the rights in 1999, it was then produced by Dewald Leichtflugzeugbau Gmbh of Bad Schönborn, Germany and more recently by Airkraft Gmbh Leichtflugzeugbau of Beringen, Switzerland, who seem to have gone out of business in about 2010 and production ended. Originally supplied ready-to-fly, later the aircraft was supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft. Design and development
The aircraft complies with the Fédération Aéronautique Internationale microlight category rules. It features an unusual diamond-shaped biplane, strut-braced closed wing layout, a two-seats-in-tandem enclosed or open cockpit, fixed tricycle landing gear and a single engine in pusher configuration. The upper wing is swept back, while the lower wing is straight, but mounted further aft. The two wings are joined by swept tip rudders. The elevons are mounted to the lower wing only. The aircraft is made from bolted-together aluminium tubing, with its flying surfaces covered in Dacron sailcloth. Standard engines available include many models of Hirth, Rotax, BMW and Verner 133M powerplants, ranging from . Variants
