I tend to ignore any gliders at the various museums that I visit, however, the Czechoslovaks had such a long and proud heritage in producing excellent designs that it would be rude to do so. The Radek 3 first flew from Kbely in 1937 but the subsequent German occupation prevented any further development. In 1951 the frame was donated, by its creator František Kantor, to the the Národní technické muzeum in Prague for display.
