Sportavia-Pützer SFS 31 Milan explained

The Sportavia-Pützer SFS 31 Milan is a single-seat motor glider that was produced in Germany in the early 1970s.

Design and development

The Milan was created by essentially combining the fuselage of the Fournier RF 4 with the wings of the Scheibe SF-27.[1] [2] [3] The resulting aircraft is a conventional motorglider design, a low-wing cantilever monoplane with a nose-mounted engine.[3] The undercarriage consists of a single retractable mainwheel, a fixed tailwheel, and an outrigger under each wing.[4] Construction is of wood, skinned in plywood and fabric.[4] The designation was created by combining the initials of the manufacturers involved (and Scheibe), and adding the sum of the model numbers of the two constituent aircraft designs.[3]

The SFS 31 prototype (registered D-KORO) first flew on 31 August 1969[3] and soon replaced the RF 4D in production at Sportavia-Pützer.[5] In 1971, Hans Huth piloted an SFS 31 to third place in the German national motorglider competition.[6]
