The Sukhoi Su-26 is a single-seater aerobatics plane from the former Soviet Union, powered by a single radial reciprocating engine. The Su-26 has mid-mounted straight wings and fixed landing gear, the main gear mounted on a solid titanium arc. The Sukhoi Su-26 made its first flight in June 1984, the original four having a two-bladed prop. The production switched to the Su-26M, with refined tail surfaces and a 3-bladed Hoffman prop. Further refinements were made, and the model won both the men's and women's team prizes at the 1986 World Aerobatics Championships. The modified Su-26M3 with the new M9F 430-hp engine dominated the 2003 and 2005 Aerobatic World Championships as well as the 2004 European Championships.
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. The Su-29 is ideal for the initial pilot aerobatics education, flight training and participation of pilots in aerobatics competitions and air shows, as well as for maintaining flight skills of military and civil pilots.
