UTVA C-3 Trojka / BC-3 / Ikarus 251 / Cijan C-3 Trojka

TerryLeave a comment

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 Dragoslav Petkovic and the prototype was built by Ikarus as the Ikarus 251.

The prototype first flew towards the end of 1946. Series production took place at Utva as the C-3 and the first production Trojka were delivered in 1949. 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. Later examples were powered by a 105 hp Walter Minor 4-III engine from 1953. About eighty were built.

The type was operated by the Yugoslav Air Force.

U-Turn Flat Top

TerryLeave a comment

The Flat Top paramotor fixed has an incredibly strong and well designed cage & frame. Not a single cage strike has ever occurred with a Flat Top. The cage can’t be flexed into the prop unless you fold it in half with a major crash.
The Flat Top paramotor has also set the world records for speed, distance and altitude. 18,182 ft without assistance from thermals, 280 miles on only 3.5 gallons of gas and a cruise speed of 50 mph.
