This single-engine biplane is slow and fun to fly. Designed in 1946 in the USSR, and produced consistently for 45 years afterward, it’s a big piece of aviation history. Perhaps most interestingly, the aircraft has no stall speed. Like many modern VTOL/STOL aircraft, it can even fly backward! With the engine off, the aircraft will descend at about the same rate as a parachute until it reaches the ground.
Be sure not to miss the flight manual and 3 extra liveries provided by the author!
