In one of the IL-2 Sturmovik games you could fly the Polikarpov Po-2. It's pretty fun because it can maneuver effectively at a speed below the stall speed of most German fighters, so it's pretty much impossible for them to "saddle up" on you for a tracking shot. As a result unless the AA batteries get you, or Fritz gets lucky lobbing a Mk 108 shell at you from long range, it's actually pretty safe and effective.
Interesting, seems like the Soviets love low stall speed planes. The AN-2 was also famous for having a vertical descent speed slower than parachutes at full back elevator deflection.
It was an early-war thing. Later Yakovlev designs were particularly formidable, both in game and IRL.
