Only two RT-versions (radiotechical) of the Crate flew with the Czechoslovak AF. This example served from March 1959 with 47. pzlp (reconnaissance air regiment) at Mlada, then to 10. prtlo (anti-radiotechnical air detachment) at Prerov and then back to 47. pzlp, which had in the intervening period moved to Pardubice. The frame was retired 1965 and has been preserved at LKBU, as the only surviving RT since 1986.
