First of all, the 6 .50s in the pony are not better than 4x20mm in my experience. When I get pissed off at dyin in HO's driving the Pony, I switch to the N1k and splode people like hydrogen filled baloons. Now I am not a great gunner, so others get better use out of the Pony's guns than I can, but they certainly aren't "uber" .50's. Put 6 of 'em on target at convergence... and yeah toejam blows up good, but it should. I also don't see 51's shredding B17's in a single pass. I can't do it, and most others I see trying certainly can't. Sure, there are a few experten around who shoot 20% gunnery and can do it, but that's because they are abnormally good gunners. For your average Shmo like me, the .50's in the Pony seem to have their traditional strengths and weaknesses. They have a high rate of fire, lots of ammo, and good range but with a downside of lower lethality compared to cannons. Please, what takes me 3 passes to kill in the 51 just freakin' evaporates when I'm flying the C.205 or the N1k in a single burst.
Second, enough about the Pony doing TnB. That's plain crap, it can TnB compared to a 190 yes, but the A8 is a truck. What the Pony CAN do is E fight very well. A good pony driver can maintain E, use the verticle, and "out turn" better turning planes for a short time. Get it into a pure low E TnB situation however and it's dog meat to the N1k, Spit, La5, Macchi, or even the 109. Want to prove me wrong? Do some sustained turn rate tests and post your results, but this anecdotal stuff says nothing.
Gawd, I can just imagine the wailing and crying that's going to go on when a few experten start "out-turning" "better" planes in the F4U.

Lord help us if we ever get a P38!
Their may be some issues with the 109's power, or the Pony's climb rate, I don't know. The rest of this anecdotal stuff you guys are whining about is just not true in my experience. Sure there are a few experten who can do amazing things in the plane, but that's because they are really good, not because the plane is too good.
I know it's hard to admit, but when you get your bellybutton handed to you it's likely the PILOT, not the PLANE that's responsible. Don't confuse uber-pilots with uber-planes.
