The 1943 Hungarian Rubik R-22 Futár (Courier) family of single seat, high performance sailplanes was developed between 1943 and 1958, though production did not begin until 1948.

They set numerous national records and one finished runner-up for distance at the 1958 VIIth World Gliding Championships, coming 11th overall.

[1] They were single-spar structures, composed of two half-wings pinned together centrally with plywood covering ahead around the leading edge forming a torsion resistant D-box.

Because the wingtips of the R-22SV were not rounded but squared-off, with "almond" fairings, their Frise-type, mass-balanced, divided ailerons were shorter, less than half the span, and were also narrower to compensate for the lost wing area.

It had a framed canopy with flat plexiglass windows which stretched to mid-chord, smoothly curved into the tapered rear fuselage profile.

The integral, ply-covered fin was tall and broad, carrying a large, roughly quadrantal fabric-covered rudder which reached to the keel.

Its strutted tailplane was rectangular in plan out to rounded tips and carried tapered elevators, their trailing edges almost ahead of the rudder hinge line.

[2][3] The main change on the R-22S was a higher, shorter, one-piece, bubble canopy mounted onto a removable ply fairing, extended at the rear to blend into the upper fuselage which was slightly lower, flattening the top of the ovoid.

Early production models, the B-Futár, had a one-piece bubble canopy which allowed an unbroken, deepened fuselage profile back to the fin.

[2][9] The prototype R-22 first flew in the winter of 1943 and gained its airworthiness certificate, permitting cloud flight and basic aerobatics, the following spring.
