Sukhoi

The Sukhoi Su-29 is a Russian two-seat sports aerobatics aircraft with a 360 hp radial engine. It was designed based on the Su-26 aircraft and inherited most design and technical features of its predecessor. Due to wide use of composite materials which share up to 60% of the Su-29 aircraft structure, the empty weight is increased by only 50 kg as compared to the Su-26 aircraft empty weight.
