Scheibe SF-30 Club-Spatz
Although bearing the same name as the earlier LSpatz-III, the SF-30 Club-Spatz single-seater Club Class sailplane was developed from the SF-27A Zugvogel, which it resembles, and was designed to the German Club Class requirements intended to meet the need for simple and easy to fly gliders for inexperienced pilots, which would also be strong and easy to rig.
Design work started in 1973 and the prototype Club-Spatz first flew on 20 May 1974; eight had been built by the spring of 1977 but production has now ended.
The fuselage is of traditional Scheibe welded steel tube construction with fabric covering, except that the forward fuselage is glassfibre-covered. The pilot sits under a one-piece sideways-hinging flush-fitting blown Plexiglas canopy, and his seat and rudder pedals are adjustable. Landing gear consists of a fixed unsprung monowheel with brake, and a sprung tail skid. Wings and tail surfaces are of composite glassfibre construction, with the outer surfaces made wholly of glassfibre supported by plastic foam; there are spoilers in the wing upper surfaces. Instead of the SF-27 Zugvogel's all-flying tailplane, the Club-Spatz has a conventional tailplane and damped elevators, the latter having an adjustable spring for trimming.
