The Weller UW-9 Sprint is a German ultralight aircraft designed and produced by Weller Flugzeugbau of Bibersfeld. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.[1]

Design and development

The UW-9 is intended as a nostalgic 1930s style design that would comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced parasol wing, a two-seats-in-tandem open cockpit, fixed conventional landing gear and a single engine in tractor configuration.[1][2]

The aircraft fuselage is made from welded steel tubing, with bolted-together aluminum tubing spar ladder-construction wings, all covered in doped aircraft fabric. Its 9.8 m (32.2 ft) span wing has an area of 13.3 m2 (143 sq ft) and a cut-out in the centre trailing edge for rear cockpit access. The wing is supported by "V"-struts and jury struts. The tailplane is also supported by "V"-struts. Standard engines available are the 70 hp (52 kW) Sauer UL 2100, the 75 hp (56 kW) Limbach L2000EA, the 100 hp (75 kW) Rotax 912ULS four-stroke powerplants, or the 85 hp (63 kW) Rotec R2800 radial engine. The Sprint is approved for aero-towing gliders and banner towing in Germany.[1][2]
