Please don't take offense at this, because this is not meant to be offensive, but who in their right mind would fly a Bi-plane against an La-7 or another later war plane?
Mind you, I have no interest in Bi-planes, and therefore know very little about them, but don't most have a top speed of around 120 kts?
I just don't see it being a worthwhile addition to the MA. As I said, I'm biased, having no interest in Bi-Planes.
Bi-girls...now that's another story.....
