History
The SF 27 is an evolution of the migratory range, the constructed Rudolf Kaiser in disc - aircraft. The first flight of the designed according to the rules of that standard class SF -27 took place in 1964. As a competitor to the Ka 6e about 120 units were built. As a single pattern, the SF had 27b 17 m span. The hull was derived from migratory IIIb and shortened somewhat similar to this is the steel tube fuselage in the front area covered with plastic in order to achieve a higher aerodynamic quality. The wings have a Wortmann profile and the elevator is designed as a floating elevator. The SF 27 only has a focus clutch which is used for aero tow and winch launch alike.
The SF -27 was built in the version of SF- 27M was the first motor glider with a retractable engine in serial production. It is self- bootable. Wing of the SF- 27M arrived in combination with an RF-4D - hull at SFS -31 "Milan " is used, a co-production ( ten copies) of Sportavia - Pützer and disc. In a single piece called SF- 27MCi the body of the SF- 27M and GfK - wing of the Standard Cirrus were combined. In Loravia in France SF -27 were built as LCA -10 and LCA -11 " Topaze " under license.
