The Scheibe SF 28 Tandem-Falke (English: "falcon") is a German motorglider that was designed by Egon Scheibe in 1970 and which flew for the first time in May the following year.[1] It was a development of the Scheibe Falke with (as its name suggests) seating in tandem rather than side-by-side as in the original Falke design.[1][2]
The SF 28 is a low-wing, cantilever monoplane of conventional design with a large perspex canopy. The undercarriage consists of a non-retractable monowheel and a steerable tailwheel, linked to the rudder.[2] Small outrigger wheels are fitted to nylon legs under each wing.[1][2] The fuselage is of steel tube construction, covered in fabric[1] and the wings are constructed of wood and fabric around a single spar.[2]
Operational historyedit
Scheibe entered at least one Tandem-Falke in the German Motor Glider Competition of 1977.[2] At least one SF28 was used by the Spanish military as 'UE 16-1' and demobilized in April 2008.[3]
