Does anyone know what year this type entered service and how did they perform against the Luftwaffe?
:confused:
-
The Yak-3 entered service in the Summer of 1944.
It had great success against the Luftwaffe. Some people will claim that the Yak-9U is the better performer, but really they are different beasts. The 3 was a lightweight fighter, that was supposed to have nearly the equal in speed/climb, but better manueverability. The flipside, was that it was a bit more fragile.

It had better roll/turning characteristics. I'd prefer the Yak-3 over the La-7 for Soviet sorties, if they added it...
-
No, it was not the equal to the Yak9....
The Luftwaffe didn't issue commands to pilots NOT to engage the Yak3 under 15k alt (or so), just the Yak9.
The Yak 3 was underpowered, but was more manuverable, from what I remember. The LW didn't have any problems fighting it (at least not the restrictions placed on fighting the Yak9)

Err, I thought the order was to avoid combat with "Yakolev fighters without an oil cooler under the nose" (paraphrasing here) which covers both the 3 and the 9U

I thought it only applied to the 9? *scratches head*
-
One other thing:
The Yak-9U and Yak-3 both had the Vk-107 engine, yet the Yak3 was a bit lighter. So I don't think it was underpowered.
Maybe you're thinking of the Yak-7?

Sikboy,
No, the wartime Yak-3 had the VK-105 engine. The Yak-3 with the VK-107 engine was too late to see service in WWII.

According to http://www.wio.ru/tacftr/yak.htm (http://www.wio.ru/tacftr/yak.htm) , Yak-3 with VK-107 was too late for WW2 and only 48 were built.
Comparison of Yak-3 and Yak-9U:
Max speed at sea level: 567 / 575 km/h (352 / 357 mph)
Max speed at altitude: 646 / 672 km/h (401 / 418 mph)
Altitude of max. speed: 4100 / 5000 m (13450 / 16400 ft)
Climb to 5000m (16400ft): 4.5 / 5 min
Turn time: 17 / 19.5 s
Ready weight: 2692 / 3200 kg ( 5930 / 7050 lb )
Yak-3 was much lighter with less engine power,slightly slower, but better climbing and turning.

Yes, German pilots were issued warnings about the Yak-3, before the 9U came around. It's in my Military History of WWII book.

This is the Yak I want...
445 mph

Very nice, and it's only 96 mph slower than this....

541 mph ground speed on second leg of world record run... 9 mph tail wind helped.
My regards,
Widewing

If it was up to me Holden would get his Yak, and Widewing would get his Bearcat ... I don't think either would be much of a threat since both are unarmed racers. ;)

Rarebear wasnt always so fast. Yikes!
-
what kind of Yak-3 engine did they use in niemen (or whatever that is:confused:) ? the VK 105 or 107?
-
used Klimov M105PF2 1220hp (1300hp?) engimne.
-
The Yak-3 serial production which began in March 1944 was equipped with the VK-105PF2 engine. The VK-105PF2 engine was actually the M-105PF2 engine, the designation only changed in 1944 from "M" which stands for "motor" to "VK" which is the initials of the chief-designer V. Klimov
Take off power of M-105PF2/VK-105PF2 was 1290hp.
Take off power of VK-107A (Yak-9U and postwar Yak-3) was 1650hp.
-
Peristroika's (now Czechmate) 445 was a Reno lap speed. Faster in the long straights... not bad for a trainer. I did a little work on it for Bob Yancey during its conversion to racing form.
Rare Bear's best lap speed in Reno '03 was 495
-
From what I've read, the Pilots plane was the Yak-3.
Frigging wonderful.
I've seen one flying, a delightful little plane :)

Oops, my bad.
At first, I was going to say "I was drunk" which was the case, however after looking at it, it turns out that I was mislead by a bad source.
This:

Is a very bad source. Filled with typographical errors, and total mis-prints, to the point that you have no idea what is correct, and what is not.
I bought it for Profiles, and hoped that it would be a good dedicated source, but I think it might have been translated poorly or something, because it's just bad.
(but it does have lots of pretty pictures!)
