You're going way off tangent and totally taking things the wrong way.
No I'm carrying your argument to its end and that end ain't pretty for the 410.
The P-51, the Typhie, and the 190a8, are all very poor dogfighters.
Plain false. The 51's a great dogfighter. Just give the exact benchmark and I'll get a 51 past it.
The Tiffie's poor, yep. Said as much. And the A8 too, so why are you picking these as positive analogy for the 410? The 410 will not have the Tiffie's redeeming quality that enables it to be a passable dogfighter and good "killer": speed and acceleration. The A8 has bad paper figures and in practice is the worst sustained turner in the whole game - you never see it sticking around in fights because it quickly gets clobbered, and the only exceptions to this in all of AH history can be counted on the fingers of one hand: Nath, KillnU (who admitted that there was no secret uber envelope, it (and Im paraphrasing now) is just him flying the living poop out of it), and... I can't think of anyone else. And the 410 has worse numbers yet, so the only way this comparison pans out to the benefit of the 410 is
if the 410 fortunately turns out to have some surprise characteristic like the 152's great E retention in initial cornering. Even then it'll be an A8 that's slower, easier to hit, and less maneuverable.
They are potent killers but their manuverability is sorely lacking with regards to turning circles, performance, and handling quirks. Yet they are still quite capable of engaging in dogfights every day in Aces High, often against more nimble foes.
The 51 yes, as far as being lethal (disagree on those negatives). But the 410 has no comparable performance figures.
The Tiffie to a lesser degree because it's a much worse turner and its major attribute is speed+acceleration for disengage faster than most other planes can do anything about. The 410 does not have this attribute.
The A8 does have very similar stats to the 410 but the 410 would have one less thing which the A8 seriously relies on (roll) and have many other stats diminished (top speed, powerloading, wingloading).
I was saying that just because something doesn't have the best manuverability doesn't count it out. Hence that's how my comment tied to the 410 and its poor stats.
Those 3 planes can't be counted out
because of their other qualities. Qualities that the 410 doesn't have. What qualities does the 410 have that would keep it competitive? Like I said at the very beginning of these 410 discussions, the 410 is a 110 with same powerloading, more wingloading, same toolshedding potential, less survivability. The only bonus is MK103 and BK5 guns and cockpit visibility with the lighter gun packages, and those qualities can't be taken in a vacuum. They belong in the rest of the 410 context: a platform with worse paper figures than its predecessor the 110 and as bad or worse than the A8. If anything, the way I see it the 410 will be the 190A8 of twin engined fighters.
As for the numbers, my point was that among similar loadouts, similar weight ratios, hp ratios, you still get significantly different craft. The 410 and the P-38 are nearly identical in the stats, hp/weight, weight/area, etc. Therefore you're saying the P-38 is similar to a 110 (assuming your comment the 410 being the same loadings as the 110). You would hardly compare the 2 (38 v 110) as the 38 is clearly superior.
The 38 isn't similar on paper. It's got much better powerloading, competitive with single engined fighters, and its wingloading as an agility metric is the only one of all twins with an asterix: fowler flaps. So the two aren't similar on paper. The 38 is a major handful with no flaps or just 1 notch of flaps, with a wingloading comparable to the 410 and A8, much higher than the 110's.
So, the comparison is much better to the next closest thing to a 410: the 110.
So my point remains: It's not just comparison to 110 stats. The handling, the BnZ, the internal weapons (no drag) the better rear guns (able to fire down, low, left and right) and the forward visibility -- the entire package would be more effective, given the same pilot skill, than a 110G.
Handling: the 410 has same powerloading and worse wingloading.
BnZ: Up to 15k the 410 has basically the same top speed as the 110, and that top speed isn't competitive with the planes. Let's take the A8 for comparison, it has roughly similar performance specs: the A8 can make just a few passes and then has to bug out. The 410 would be the same only with worse top speed and roll rate. The heavyweight bonus to zoom momentum would be offset by heavyweight malus to agility at the top of the zoom. Any fighter in the area would quickly pavlov at the sight of a 410 on its props, the same way most probably do for an A20 in that position. You have 500HP more for roughly the same top speed and the same powerloading, IOW the same BnZ performance as a 110 that weighs 2 tons more. How many 110s do you see doing "killer" BnZ in the MA? All the other twins are as good or much better than the 110 at this.
Rear guns..... You're arguing rear guns that'll trigger autopilot on a slow, big, unmaneuverable plane. If you're in the rear guns you're probably about to die. One 50cal isn't going to turn it into an A2A killer.
Visibility is better but that doesn't undo all the major (almost an understatement) handicaps.
