Antonov A-13

The Antonov A-13 was a Soviet aerobatic sailplane flown in the 1950s and 1960s. It was a small, single-seat, all-metal aircraft developed from the A-11 which could optionally be fitted with that aircraft's longer-span wings. It was a mid-wing monoplane with a tadpole-like fuselage and a V-tail.
