Allrighty. I've got a few questions about exactly which variants/models/series we have and some of their specifications.

A6M5B: Which Sakae engine does our version have? The 1,020 HP 21 or the 1,130 HP 31?

B-26B: R-2800-5, -41, or -43? I've seen all three engine choices listed as having been used in the Marauder.

Macchi twins: Is our 202 using the DB601n? What version of the DB605 is in the c.205? I have a 1,350 HP rating for the 605 in the c.205, but no version #.

FW 190A-8/F-8: Coupla possibilities here. Most likely the BMW 801D-2 at 1,730 Take Off HP. Correct?

Hurricane: Are both of our planes using the Merlin XX with 1,280 HP?

Lavochkin: Both with ASh-82FN rated at 1,850? Doesn't seem right to me.

Mosquito: Merlin XXI's at 1,250 or XXV's at 1,650?

P-47D-25: Stronger R-2800-59 with 2,535 HP as in the -30? Or the same -63 that's in the -11?

Mustang B: I'm assuming that we have the later V-1650-7 engine which is also used in the D model. I've seen alot of range for the HP rating tho. 1,590 T.O.?

Spit 9: What's the full designation of our model? MkIXb or MkIXe? I'm assuming that we have a L.F. version. So we most likely have the Merlin 66 rated at 1,650 HP.

Tempest: Our Tempest is visually a Mk V Serie II, which should mean a Napier Sabre II. Coupla varients of that motor, but the only HP rating I can find is 2,180. That's for the Sabre IIa which should be the same motor as in the Typhoon. Sound rite? I've run across a few refrences that list the cannon in the Mk V Serie as having 200rpg. Has this been whined about before?

Yaks: The -9T has the 105PF-3 at 1,240 HP and the -9U has the VK-107A at 1,650? Da? I don't have any Yak specific books and the web info is pretty sparse.

FWIW, I'm working on some performance/data pages that are more in-depth than what HTC has provided. Anyone who remembers Hoof's WB pages should know what I have in mind.

No, Merlin 61. 1560hp, iirc

Don't delve too deeply into the exact model of Spit IX in AH, it is a sort of hybrid, combining ammo and ordinance options from the later planes with the performance of the 1942 model.

This is correct. The La5FN and the La7 used the same engine. The La7 had several critical changes to its aerodynamics, and a very few weight saving improvements, to get its performance boost. What most people don't know is the La5FN will perform very much like the La7 in AH, it just won't reach as high a final speed.

Mustang B: I'm assuming that we have the later V-1650-7 engine which is also used in the D model. I've seen alot of range for the HP rating tho. 1,590 T.O.?

If I remember correctly, Pyro did say it was the -7 engine.

Yaks: The -9T has the 105PF-3 at 1,240 HP and the -9U has the VK-107A at 1,650? Da? I don't have any Yak specific books and the web info is pretty sparse.

My "Soviet Combat Aircraft of Second World War" book list the -9T as using the M-105PF with 1,180 hp at altitude (not sure if thats critical altitude or some other measure) and the -9U with the VK-107A, which has 1,500 hp at altitude. FYI since you asked earlier about the La5FN/La7 series, it lists both of them with the ASh-82FN engine rated at 1,470 hp at altitude.

AFAIK:

P-51B as modelled(visually and I think also in performance) is a B-5-NA which had the V-1650-3 engine. Critical altitudes differ from the P-51D, which also points to the early engine.

The B-26B in Aces High is "Flak Bait", which was a B-25B-25-MA with R-2800-43 engines. The version depicted in AH is at least a B-26B-10-MA because it has the bigger wing - and since the R-2800-43 was fitted from the B-26B-4-MA onward, it's a safe bet that the Marauder in AH has these engines.

The A6M5b had the 1,130HP Sakae 21 - which had the same "dry" HP rating as the Sakae 31, the only difference being that the 31(used in the A6M6 and A6M7) had a methanol-water injection system to further increase power.

Both the Hurricane IIC and IID should only have the Merlin XX engine.

The Mosquito is a FB.VI Series 2 and so has 2 Merlin 25s rated at 1,635hp.

The Spitfire IX has a Merlin 61 engine. Properly it should only have the 2 20mm and 4 .303 armament available. It also should lack rockets. If those were properly modeled it would be a Spitfire F.Mk IXc. As it is, it is a mish mash of a Spitfire F.Mk IXc and Spitfire LF.Mk IXe, being more of the former than the latter.

The Lavochkins are indeed both powered by the same ASh-82FN engine.

The Tempest is a Mk V Series 2 version, which, AFAIK, only refers to the fact that it has 4 Hispano MkV cannon instead of the Series Is 4 Hispano MkII cannon. The engine in both the AH Tempest and Typhoon is a 2,180hp Napier Sabre IIA engine.
