Rubik R-26 Góbé

gober26

 

The R-26 Gobe metal and fabric two-seater sailplane was developed from the R-23 Gebics and R-24 Bibic and has a conventional fabric-covered cantilever metal tail unit with the tailplane mounted part of the way up the fin, and lower aspect ratio (10.88) constant chord wings.
 
The first of two R-26 Gobe prototypes made its maiden flight on 6 May 1961 and an initial production batch of 50 was put in hand. The cantilever high wings are single-spar all-metal structures with a leading edge torsion box and fabric-covered from the 35% chord line aft; the slotted metal ailerons are also fabric-covered and DPS air brakes are fitted. The metal monocoque fuselage is partly fabric-covered and the landing gear consists of a non-retractable monowheel with a torsion rubber spring and a brake. The two pilots are seated in tandem under a sideways-opening blown plastic canopy.
