Utva Trojka

The Utva C-3 Trojka (Trey) was a light aircraft built in Yugoslavia shortly after World War II as a result of a government competition to develop a new, domestically built aircraft with which to equip the country's flying clubs. The winning design was submitted by Boris Cijan and [Emin Hadzic]] and the prototype was built by Ikarus as the Ikarus 251. Series production took place at Utva as the C-3. It was a conventional, low-wing cantilever monoplane with fixed tailwheel undercarriage. The pilot and instructor sat side by side under an expansive canopy. The type remained in production until the mid-1950s with later examples powered by the more powerful Walter Mikron 4.

gollark: Actually, you should use (praise be!) ffmpeg.
gollark: I just have a script which reads metadata from my music library and converts it to DFPWM as a multitrack tape image.
gollark: It is a shame they didn't do Opus, somewhat. Although DFPWM is simple enough to implement in CC if necessary.
gollark: No.
