That´s why i posted the tested climb performance. It´s very close (normal power) to the performance claim of the VVS (the weight was a bit higher). And with normal power, max. speed was 490km/h at sealevel.

woah, that is a BIG discrepance with the AH charts and with the La5 in AH itself! 490km/h is 306mph, and without wep AH's La5 runs at 335mph! that is 30mph of discrepance!

And what about the Fw190A8, niklas? does anyone else have seen the 360mph as a SL top speed for the A8 or is only me?

Ahh, geez, niklas, never realized the La-5FN was really only as fast as a Zeke, and a slow one at that

no leonid, according to the test in Rechlin it is still 15km/h faster than a zero - with normal power!! ...wwwWRRRRUUUUUMMMmmm... a real speedking

RAM might I suggest Soviet Combat Aircraft of the Second World War : Single-Engined Fighters
by Yefim Gordon, Dmitri Khazanov ?
http://www.amazon.com/exec/obidos/ASIN/1857800834/qid=982243228/sr=1-2/ref=sc_b_2/107-1525636-6536510

If your interested in VVS aircraft and performance, its the best single source I have seen.

One thing we should point out. If anything, the La5fn and the Yak-9U (and most likely also the La7) perform too poorly, since Pyro used the worst case performance data available.

For example, our Yak-9U has its max speed at 417mph at around 18,000 ft (which is the worse case). Another set of data availble for this aircraft states that the Yak-9U should do 437mph at 18k, which would make it easily the fastest aircraft in AH at that altitude.

If you think the Yak-9U or La5 is scary now (which many people do), it can only get worse

Well, again I am talking about that link's numbers, and ,well, I dont know if niklas is joking or serious (seems that joking).

Ah, and still no word regarding the Fw190A8 making 360mph on the deck?

RAM, I will check the Pilots Handbook charts when I get home this evening that has some nice performance charts for the 190A8, too see what it says about 360mph.

RAM, telling wrong or fantasy numbers about an aircraft wouldn´t be joking, but lying. The test was done in Rechlin, and the number exists.

Is 630km/h for a 1850hp fighter at sealevel with naca230 airfoil a joke? The number exists for the La-7 (wep, 10min rating).

In the link you find a test with 580km/h for the La-7. 50km/h more (630km/h) is equivalent to ~4-500hp. A joke?

Niklas, I know almost nil regarding soviet WWII aircraft, that is why I didnt know if you were serious or not. Simple

Verm, please let me know about what your sources say about the A8. I'd like to know about funked ,too.

Hmmm I keep getting a 404 file not found error whenver I try any link from the site other than the main page. Anyone else?

RAM, I checked the performance charts from the english translation of the Pilots Handbook that Funked sent me.

The Handbook Charts match the Aces High Charts exactly, including the supercharger boost overide, which corresponds to AH's WEP.

I would scan them for you, but right now my scanner when "belly up" (ie it died) a couple of nights ago.
