Yak-55/55M, 1982/1989
All-metal monoplane with non-retractable titanium spring landing gear. This airplane was specifically designed to replace Yak-50 as the main aerobatic competition aircraft. The "M" modification (data after the slash "/") offers faster rolls thanks to a shorter wing. Its notable drawback is a mandatory (and costly) wing attachments replacement at 250 total hours At the Arseniev plant, a hundred Yak-55 and Yak-55M nave been built so far. Both versions are widely used in aeroclubs throughout ex-USSR. The 55/55M are enjoying a enduring popularity in the West as solid, low cost advanced aerobatic aircraft.
