The Dallach D.3 Sunwheel, also known as the WDFL Sunwheel and more recently the Fascination Sunwheel, is a fully aerobatic, single-engine, two-seat biplane, homebuilt from kits. It was designed and marketed in Germany.[1]
Design and development
This Wolfgang Dallach design, like his Dallach Sunrise, was marketed by WD Flugzeug Leichtbau (WDFL),[2] the kits at least partly built in the Czech Republic by UL-Jih Sedláĉek Spol s.r.o.[3] The Sunwheel is constructed from metal tube and is fabric covered. It is a single bay biplane with a single I-form, faired interplane strut on each side. The wings are both swept and staggered. There are ailerons on both upper and lower wings, externally interconnected. Cabane struts support the upper wing over the tandem, open cockpits. The Sunwheel has a fixed tailwheel undercarriage, with the mainwheels hinged from the fuselage on V-form, cross-connected struts. Some Sunwheels have wheel fairings.[2]
The Sunwheel is usually powered either by a 60 kW (80 hp) Rotax 912 UL flat four or a 48 kW (65 hp) Sauer ULM 2000 engine.[2]
Operational history
48 Sunwheels appeared in mid-2010 on the civil registers of European countries excluding Russia.[4]
