Yak-3 is actually a later yak than the Yak-9u, it would be pretty balanced in the MA, it's slower than the the yak-9u, turns better (turns 360 degrees in about 3 or 4 less seconds than the yak-9u IIRC and has the same armorment as the yak-9u (which keeps the spray and prayers out of it) so all in all it's a good plane that would be great for the Russian plane set
Now all the Russians need is a Il-2M3 with 2 37mm cannons
