Luftsport-Club Friedrichshafen LCF-2



This single-seat Club Class sailplane is intended for use as a trainer, for competition flying and for aerobatics; it was designed in 1971 as a successor to the earlier LO 100 and the prototype was built in approximately 4,000 hours by five engineer members of the Luftsportclub der Zeppelinstadt Friedrichshafen. It first flew on 22 March 1975 and won first prize at that year's meeting of the CUV or Oskar-Ursinus-Vereinigung, Germany's equivalent of the Experimental Aircraft Association.
The cantilever shoulder wings are single-spar wooden structures, with Conticell foam ribs and plywood covering; there are Schempp-Hirth air brakes on the wing upper surfaces. The oval-section fuselage is a welded steel tube structure with glassfibre covering of the nose section and fabric covering of the rear half. The plywood tail unit is filled with Conticell foam, and the landing gear consists of a semi-recessed non-retractable monowheel and a tailwheel. The pilot sits under a one-piece flush fitting cockpit canopy.
There were plans for production of the LCF II by Scheibe if sufficient orders for it had been received, but these were dropped.
