TheUtva C-3Trojka (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 byBoris Cijan andDjordje T. Petković and the prototype was built byIkarus as theIkarus 251. Series production took place atUtva as theC-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 powerfulWalter Mikron 4.
