The Scheibe Sperling two-seat light high-wing monoplane first flew August 1955, and was developed with new wing and tail as SF-23A and built in numbers until 1963.
Designed by Egon Scheibe, the prototype was powered by an 65 hp Continental A-65-8 and first flew on 8 August 1955. Production machines, the SF-23A, had either 65 hp or 85 hp Continental and the predicted price was £1400.
The fuselage is fabric covered steel tube and the wings are single-spar wood with fabric and plywood covering.
The SF-23B was powered by a 100 hp Continental O-200-A.
The SF-23C, powered by a 115 hp Lycoming O-235, was suitable for glider towing.
Production was completed in 1963.
