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. Four variants were serially produced, with the R-22S Június 18 the most numerous. There were several improvements within the types and there were three one-offs. Overall, 104 were built. They set numerous national records and one finished runner-up for distance at the 1958 VIIth World Gliding Championships, coming 11th overall.
