The Sukhoi Su-26 is a single-seat aerobatic aircraft from the former Soviet Union. It is powered by a single 400 HP reciprocating radial engine. The Su-26 has mid-mounted straight wings and fixed landing gear. The main gear is 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. Production switched to the Su-26M, with refined tail surfaces and a 3-bladed propeller. Further refinements were made that resulted in the model winning both the men's and women's team competitions at the 1986 World aerobatics championships. Experts consider the Su-26 one of the best aerobatic aircraft in the world.
