Guess we're gettin' a 39Q!

"AHT"

Ok.

"How is 1325 the more common figure?"

Because if you make a search with term "V-1710-63 (E6)" you find 1325 hp and 1590 is never mentioned. I don't understand why. I think it is essential to know with which hp the maximum alleged airframe speed is achieved, although the max speed seems to be debatable too.

Here is some data of P-51's V-1650-7 for comparison:

http://www.icon.co.za/~pauljnr/specs1.htm

1720hp on WEP so is the top speed of 437mph achieved with CID (T.O.?)or WEP? Or is the 437mph achieved with the most commonly quoted 1649hp and with 1720hp it could actually do 501mph?


From this site I found 1580hp for V-1710-73

"bojový 1580 hp (1178,2 kW) v 762 m, při 3000 ot/min. a plnicím tlaku 60,0 in Hg (2032 mbar/hPa)"

Charge that is the problem i am having looking for specs online.
They only give one number. We are then left to try and figure out what it is, TO, normal, or wep? Very frustrating IMHO.

I've seen this too, but the rating was for 2,500 feet. The V-1710-63 was installed in the P-39K and the P-39L too. If I recall correctly, the P-39L was rated at 367 mph at 2,500 feet, 386 mph at 9,000 feet and 373 mph at 12,000 feet. Again, this is quite competitive with the late war beasties at common AH2 altitudes.

The primary drawback of the P-39 was poor performance at altitude. That's not much of a factor in Aces High. Down low, it should be very competitive. 386 mph at 9k is faster than the Yak-9U. The gap is even wider at 2.5k. Indeed, at 2.5k it's about 20 mph faster than the Spit16 and has a similar wing loading.

I read a combat report submitted by Lt. Hugh Dow of the 346th Fighter Squadron. Dow obtained his first Luftwaffe kill flying a P-39L in 1943. He was also able to log 8 hours of flight time in a captured 109. Being familiar with the 109, the next time he encountered one, he didn't hesitate to take it on in a classic one on one duel.

Spotting each other, Down turned his P-39Q-15 into the 109 and they merged on opposite headings. Both pilot reefed their fighters around in punishing left turns. Dow saw vapor streamers coming from the 109's wing tips. Dow knew the the P-39 would out-turn the Messerschmitt. Within two turns he gained nearly 180 degrees. Having used up his cannon ammo, and most of his .50 rounds strafing, Dow opened fire at close range in a hard turn. He fired the remaining .50 cal ammo, scoring hits which caused a fuel leak. He then continued shooting with his four .30 cal MG, igniting the fuel. The 109 pulled into vertical climb with Dow's P-39 right on its tail. At the top of the climb, the 109 pilot pitched off his canopy and jumped out. Dow climbed past the burning 109 and rolled off to the right. He watched the 109 crash onto a road at the entrance to a bridge Dow had just recently strafed. The German pilot landed in some brush near the road and Dow flew past him wagging his wings. The German was seen to wave his hand in return.

In the MTO, the P-40 flew more than twice as many combat sorties as the did the P-39.  However, four times as many P-40s were lost. Loss rates per sortie for the P-39, in the MTO, SWPA and Aleutians were typically half that of the P-40.

Loss rates to ground fire in the MTO were, in order of losses per sortie:

P-47 (.2 per sortie)
P-38 (.3)
P-39 (.4)
P-40 (.8)
A-36/P-51 (.8)

The Soviets concur that the P-39 was more resistant to damage than the P-40 and that pilots shot down in air combat were more than twice as likely to survive if flying the P-39 as opposed to the P-40. 1,200 lb of Allison armor behind the pilot must have been beneficial.

My regards,

Widewing


man i was hoping it was gonna come in january, hopefully its in early febuary

Tougher than a P40, Fast OTD, armed with a BFG, probably a better forward view than a Corsair for pulling lead (no engine to look over), low wing loading? I got wood :)

Oh yea and a nose gear for kewlness

What kind of ord can this thing carry?

How about range and drop tanks?

One 500lb or one 250lb bomb or a 75 gallon drop tank. About 24 minutes in the MA at MIL power, increasing to roughly 40 minutes with the drop tank.

Should be a good ride for killing light-skin GVs using the 37mm. The 500 lb bomb should take care of anything, except the Tiger (a direct 500 lb bomb hit may be enough).

Where does he get the E for that last one?  It looks like the sort of maneuver you pull on a blind and hamhanded noob in AH.
