After the construction of powered aircraft again became permissible in Germany, Scheibe began work on a small two-seat light aircraft of mixed wood-steel-fabric construction with quickly-removable wings. Known as the SF-25 V1 Sperling (Sparrow), powered by a 65 hp Continental A65 engine, and registered D-EBIN (c/n 2001), the prototype made its first flight on August 8, 1955. It was followed by 26 production aircraft (of which the first flew in September, 1958) produced in three versions differing only in powerplant:
SF-23A. With a 95 hp Continental C90-12F engine, 16 built
SF-23B. With an 100 hp Continental 0-200-B engine, 4 built
SF-23C. With an 115 hp Lycoming 0-235 engine, 6 built
The versions with Continental engine were suitable for touring and training. The more powerful Lycoming version was recommended for glider-towing. Three others were built by amateur constructors,one SF-23A,D-EMAW c/n 2500, and two SF-23Cs, D-ENZE c/n 3501, and the pictured aircraft that was built in June 1961."
