Rubik R-27 Kópé (Scamp)

MME R-27 Kópé
This single-seater training sailplane first flew in prototype form on 7 October 1961 and is closely related to the R-26 Gobe, having basically the same fuselage, and 80% of the components of the two types are interchangeable. The wings are the same as the R-26's but of reduced area and lower aspect ratio (9.35), and the fuselage is very much the same metal monocoque structure, partly fabric-covered. The tail unit reverts to the cantilever 'butterfly'-type of the R-25 Standard, again of fabric-covered metal construction with a trim tab in each elevator. Landing gear consists of a non-retractable monowheel with torsion rubber spring and a brake, and the pilot is seated under a removable blown plastic canopy.
