The Zlín Z-126 Trenér II is a Czechoslovak multipurpose aircraft. It was developed by Karel Tomaš in the early 1950s to replace the Z-26 . It was used as a training aircraft , for towing gliders and, since it was suitable for this, also as an aerobatic aircraft .
history
In contrast to the Z-26, the construction switched from the mixed to the all-metal construction, but the first series models still had a rounded tail made of wood, which was later replaced by a square one made of metal. The wings and fuselage had been changed slightly and the instrumentation improved. All Z-126 had fabric-covered ailerons. The Walter Minor 4 III drive was retained. The prototype flew for the first time in 1953. Series production started that same year in Otrokovice and comprised 168 machines. The Z-126 was used both civilly and militarily and was also exported. In the air force of the ČSR it flew under the designation C-105 .
Use in the GDR
The first three Z-126s were delivered to the Kasernierte Volkspolizei (KVP) in spring 1954 and were still equipped with a wooden tail unit. Twelve more were added by 1956. These Z-126 flew with dark green camouflage over everything and, in order to bypass the Allied flight ban, with Soviet emblems. They were mainly used to tow gliders . After the NVA was founded in 1956, the KVP gave the remaining 13 Z-126s to the GST . Two had already been lost in accidents.
In 1956 four Trenér intended for the Kasernierte VP were delivered to the Technical University of Dresden , where they flew for the practical training of students in the aerodynamics and aircraft construction faculty. Two of these aircraft went briefly to VEB Flugzeugwerke Dresden in 1959 and flew there with the experts DM-ZZH and ZZF. In the early 1960s, these machines also went to GST.
At GST, the Z-126 were used as tow planes , for pilot training and, at the end of their service life at the end of the 1970s, for distance and instruction flights.
