In 1939 for the request of the Aeroclub of the Thechnical University, Ernő Rubik Sr. (father of Ernő Rubik Jr. the designer of the Rubiks Cube) designed the first Hungarian two seater glider.
The prototype of the R11 glider first flew in May 1940. Originally it was called Gólya (Stork). The evaluation of the test flights and the requirements of newly published airworthiness regulations resulted in a couple of modifications. The new versions got the type designations of R11a, R11b and R11b1 respectively, however the modifications applied on the different variations are not exactly known. The version, which was built in series from 1941, had got the designation of R-11b and the name of Cimbora (Buddy). Some 50 were built by Aero Ever in Esztergom, and 12 by the Aircraft Factory of Transylvania in Nagyvárad (Oradea).
The type were used for aerotow training as well as for familiarization flights on ridge-flying up to 1950.
In 1951 all remaining examples were decomissioned and later destroyed, however the plans survived.
In 1982 the rebuilding of the Cimbora was stared, which took more than a year to comlete. Since than Cimbora is a regular guest at airshows and oldtimer meetings in Hungary and all over Europe.
