Yak-9T - incredible firepower (or maybe incredible tank's lack of armor?)

[RPS69]

Sorry, but IAm a bit confused here. Why do you keep talking about 20mm power when the airplane used bores a 37mm one?

The NS37 if I remeber it well.
I'am a bit surprised to know that it could carry so many 37mm ammo.

But if there is anything bad modeled here, was this canon recoil effects on the little yak.

The same thing applyes to the il2 3m with two 37mm non synchronyzed canons.
Only the first shot could be aimed, on the second shot the plane will be absolutely out of its mark.
