I'v only heard about the corsair the first prop aircraft to break the 400mph.... never heard about the la..just a qustion if so id like to see proof http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

Corsair was first American production fighter to break 400mph.

FW-190A beat it to 400mph, so did Typhoon for that matter. And the Spitifre IX. Well, you get my point.

And yes the La-7 was faster than the Corsair, but the Corsair was fighting in Feb. of '43, while the La-7 was a mid '44 plan IIRC.

La-7 top speed is 680 kph everywhere that I can find it. The F4U-1D's top speed is 671 kph in most places I could find it.

Mind you, the two reach maximum speed in different areas. The Corsair at higher altitude and the La-7 at lower altitude.

La-7 I think still wins the award for fastest prop fighter in-game.

Which is funny since IRL the Corsair reached top speed at around 19,000 feet and the La-7 at around 20,000 ft. The numbers for the La-7 in-game match exactly those of the prototype La-7.

From La-5/7 in action:

"The standard production La-7 had a top speed of 592 km/h (367mph) at sea level. At 6,100m the La-7 had a top speed of 655km/h (407 mph)."

"A maximum speed of 680km/h (422mph) at an altitude of 6,000m was recorded with the La-7 prototype."

This (the latter part) is exactly what we have in-game. La-5/7 in Action is a great read and gives different performance numbers than what we have here. From what I have seen the performance of the VVS planes in-game are based on prototype numbers at times. Also, the machines pulled off the production lines often had significantly lower performance numbers than the prototypes, but often handled as well or better. I am NOT saying I am right, just an observation.

Right, but... http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif
Yes, prototype reached 680km/h, but serialy produced La-7 got close:

Specially prepared serial La-7 (Ser.#45210150 produced in July 1944 on factory #21, tested in August-September 1944) achieved 674km/h at 6000m;

Serial La-7 (Ser.#45213276 produced in April 1945 on factory #21, tested in May-August 1945) reached 677km/h at 6250m;

Serial La-7 (Ser.#38102663 produced in May 1945 on factory #381, tested in May-August 1945) reached 661km/h at 6000m;

Well the high alt performance is always a point of dicussion for la7 .

6000 654 serial No.452101-39
6000 672 serial No.452132-76
6000 640 serial No.452101-50 17.08.44
6000 674 serial No.452101-50 23.09.44
6100 652 serial No.452102-03 11.09.44
6250 677 serial No.452132-76 12.06.45
6000 661 serial No.452132-76 26.06.45

I reached about 695 km/h on crimea map at this time .)

Here is the track

http://www.butcherbirds.de/hypesstorage/la7topspeed301m.zip

Specs are 660 km/h at 6 km and middelfield of test is about 661 km/h
Il2 Database gives about 680 but not very reliable source as we know from other planes.

According to Olegs sources the vvs standard was around 688 km/h and production aircraft reached same high standard as prototype.

The P51 D however reaches about 705 km/h at 7620 m 3.01 m

For the Corsair D about 670 at 6000 m.

Couldnt reach this speed with u4d only 650 km/h maybe someone else can repeat the test.

So indeed the La7 seems to be faster when all "historical" data is correct at least .)

The Corsair was the first Naval aircarft to exceed 400 mph in level flight. It was not the first American fighter to do that - the P-38 was.

Skychimp, I was a victim of my own guidelines.

The prototype Corsair was the first American warplane to exceed 400mph, the P-38 was the first production U.S fighter to exceed 400mph. Is that correct? What production version of the P-38 broke 400mph, was it the P-38H in September of '42 (delivered between March and August of '43) with V-1710-89/91 engines? I thought the Corsair was produced in June of '42. I don't think production versions of the P-38F/G reached 400mph, unless in recon versions. I thought top speed of production P-38F's and G's was 395mph at around 25,000ft.?

Mixed sources on this one.

The XP-38 exceeded 400mph on February 11, 1939 during a flight between Enid, Oklahoma and St. Louis, Missouri. (Source: The Lockheed P-38 Lightning - Warren Bodie)

The XF4U-1 didn't hit 400 mph in level flight until October 1, 1940. (Source: Detail & Scale # 55)

The first production P-38 listed with a top speed in excess of 400mph was the P-38G - deliveries began August 1942. (Source: The American Fighter - Angelucci & Bowers / The Lockheed P-38 Lightning - Warren Bodie

F4U-1 is listed as having a top speed in excess of 400mph. Deliveries began October 3, 1942. (Source: US Navy Aircraft: Since 1911 - Swanborough & Bowers)

Thanks Skychimp. I think the P-38F and G had the same power and speed, its just that the G could sustain the power longer. The P-38H had more powerful engines and its top speed was reported to be 402mph IIRC. No big deal and I'm sure you have seen all this stuff, just thinking out loud.

Well, in application, I can still outdive an La7 in either a Corsair or a P-38, but the point is irrelevant since I fly Historical planeset servers where these two wouldn't be adversaries...until Korea. And even then the P-38 was all but phased out already.

Service Delivery of the P-51K in April of '44? 1,337 produced?

Gotta wonder why we don't have that, and the H. Hmmm......

the P 51 K was simply a D with an aeroproducts propeller in place of the hamilton standard.....no difference in performance, appearance or anything else

Just for the sake of it, lets not forget the fastest piston-engined plane of them all... OK, it was never used in action according to official sources but Pierre Closterman claimed to try to catch up with one of them in his Tempest (in vain http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif
