109 G6 (http://www.avpics.de/lffamp/me109hw.wmv)
YAK 3 (http://www.avpics.de/lffamp/yak3u.wmv)

Gorgeous!
Thats not the Gustav that crashed is it? (the modified hispano-built one?)
-
That is the Yak-3 with the R-2800 in it.
Mani-Yak I believe.
-
cool vids. Landing speeds sure did seem fast, but then it just might have been the camera angle and zoom. I thought all the Yaks used inline engines :noid

It is a modified hispano-built, but not the one that crashed.

Ah, ok. I wasn't aware there was more than one.

http://en.wikipedia.org/wiki/Yakovlev_Yak-3
Yak-3U - Yak-3 fitted with Shvetsov ASh-82FN radial engine with 1,380 kW (1,850 hp) in an attempt to increase performance while avoiding the overheating problems of VK-107 and VK-108. Wingspan increased by 20 cm (8 in), wings moved 22 cm (9 in) forward, cockpit raised by 8 cm (3 in). Armament of 2x 20 mm Berezin B-20 cannons with 120 rounds per gun. The prototype reached 682 km/h (424 mph) at 6,000 m (19,680 ft) and while successful did not enter production because it was completed after the war.

That 109 had a DB, yes?

Cool stuff Mip.Realy neat sein that 109 crank up and roll out.

The Yak looked like a LAla ;)
And the 109 was sweet.
The Runway was not so sweet.
Where was this??????????????????????????????

In my opinion it is not a Yak 3...............
I know this dispaly team continually refer to it as such and have some logic to do so...................
Its a converted Yak 11.............
The Yak 11 was a two seat trainer derived from the Yak 3 fuselage and wing with Shvetov Ash 21 (580 hp) engine.
Not a R-2800 nor an Ash 82 (1650 hp).
This ac does give a very nice display ( I have seen converted Yak11's like this at Duxford twice).
The logic for the display teams Yak 3 claim is that the cockpit has been re designed back to original Yak 3 single seat configuration and location....................b ut the engine is no where near the original either in power or configuration.
In fact other Yak 11 -Yak 3 conversions have taken place where by an allison engine is used although not the original engine the weight, power and shape are at least more similar than this Ash 21 variant
It quite annoys me to hear so called aero expert commentators at air shows spout about the heritage of the Merlin engined spit fire in one breath then claim that the plane before us is a Yak 3 "but with a different engine" and then recount how this plane was the mainstay of the Russian airforce.................... I suppose if a spit turned up with a nice big radial on the front they would say the same thing?

I belive they have a nice YAK-3 at dux....

It is a Yak-11, highly modified. Was originally obtained from Egyptian AF. Currently powered by a 1,450 hp P&W R-2000, 14 cylinder radial (same basic type use in the DC-4/C-54).
It sure sounds sweet...

The yak 3 is in bits at Duxford.........I was looking at them last July......there is a freshly refurbed allinson engine ready to go in.
I believe it is still the property of the OFMC.

Are you sure wide wing.......I have seen the ac White 27(F-AZIM) shown in the video a couple of times in displays at Duxford. Looking at the depth between cowl and exhaust vent it does not have space for a double row (2 x 7)radial.
I'll try to find the specs on this actual ac some where.
I was certain it was only a single row radial and assumed it was the original ash 21 or similar.

Actually, Yak-11s modified with R-2000 engines are more common than you might think. Here's one example (http://www.caapilots.com/PlaneofTheMonth/Dec2000/SamRichardson.htm)

F-AZIM is/was the property of Raymond Capel and Alain Capel.
It is one of a group of Egyptian Yak 11's rescued by a French team from La Ferté Alais.
Other Yak 11's were but not limited to F-AZNN(also modified to single seat), F-AZIR, F-AZFJ, F-AZJB.
These I think are still based at La Ferte Alais.
other than the obvious observation that they are radial engined I cannot find what the actual engine spec is.
I would be interested to know how Richardson fitted a double row unit and still used the existing exhaust vent.

The R-2000 is little more than a larger displacement R-1830. Consequently, the diameter of the engine is relatively small for its power output. Here's a R-2000-7M2 about to be hung on a Caribou. Fitting one to a Yak-11 is a major engineering task, but not especially difficult if you have the money to spend. I've located several Yak conversions (to R-2000) and I've even located one Yak-11 fitted with an R-1830 Twin Wasp.
(http://www.c-7acaribou.com/album/lgphotos/lg_06.jpg)
I can tell you that the engine note of the Yak in the video was absolutely that of a twin-row radial. God knows, I've listened to them for many, many hours, both R-2000s and R-2800s.
Vought installed a pair of R-2000s inside the their radical XF5U-1... If they could fit them in there....

I knew one of the guys had the R-2800 in it.

well it seems there are more R- 2000 engined Yak 11's than I thought.
I will check white 27 out more throroughly if its at Duxford this year.
I always dismissed it as a "wannabe Yak 3" which indeed it still is albeit a little more interesting as possibly a souped up Yak11
-
Tilt, are you going for the flying legends this year ???
I am planning for it, and will go if I can. Would be nice to meet you!
BTW, have been to Duxford 3 times before. I had a press pass in the BoB show in 2000 ;)

i hope to angus
I get back from a motor bike tour on the 7th...........
Duxford 2000......16 spits flying in formation down the flight line?
I was there:)

holy unimproved grass runway batman. this they could have found a flatter area in that field for the runway.

Yeah, you could hear that Yak clunking down the field like an old Yugo crossing a speed bump.
