If you want a good Soviet TnB fighter, that isn't so big like the La-5FN and La-7 (They could be considered a Soviet-esque Spitfire even though they were smaller all around), I suggest the Yak-3! Why? Not only is it fashionably cool () but it's got all around speed, turning, and good armament. Twin Berezin UBS MGs and one BEAUTIFUL 20mm ShVAK Cannon.
no it is very agile 1 minuit but if you keep turning it goes in a streight line every half a turn
