Im talking about a clean aircraft, and the transition from high positive to high negative Gs at a rapid rate.. I.E slamming the aircraft from +6g immediately into perhaps -4G in less than 1 second, and the effects of doing such an extreme maneuver rapidly over and over would realistically have on a real WW2 aircraft.
Wingnutt, I don't think we ever inflict that kind of punishment on a plane. I'm not an engineer or a RL pilot and, despite some notions acquired reading books, I'm not claiming I'm an expert: but I think the point is not on airplane limits, it's another one.
Think about it: how many times you keep pulling when you blacked- or redded(?)- out? In 99% of the instances, you'll release the pressure on the stick before the screen goes totally black or red. Well, black screen happens when you're pulling 6 maybe 6.5 Gs (-2/2.5 for negative), so, while in combat, you almost never reach those values. And they are well within the safe operational limits of our fighters, I presume. I think we normally pull no more than 5/5.5 Gs and -2 G. Add to that that you get a new plane every time you land, and you can see that a structural failure is really unlikely in AH. If you have a .ahf of a very heated fight of yours, run it and check the G-meter: I think you'll find out that my above speculation are reasonable and maybe true.

Mind that you can pull more than 6 G or -2 G in the game, when the screen goes black or red. You just don't do it, because it would be of no help, if not for a brief pull (G-loc is quick to come!)
So I think RL planes would take it, just because it's not so much as it seems. A total different question is if the pilots, at time, could take it: I guess we'll be able to speculate about it (and have flame wars on the boards

) about it when CT comes out and the pilot will be simulated as a "real" man and not only a part of the damage list.
Btw, nice stick stirring on the Yak!

EDITed to better clarify what I was trying to say.
