Yak-3 nearly ready to go in CA.

Im sorry to say, but I feel that this is just a waste of a good engine !
Allison's would be better off being used in American WW2 Aircraft

Lightning

Do I detect the teeniest bit of patrioteering here?

[DaveM2]

What engine should the aircraft utilize?, there are few Klimovs available......

I wonder if this is the Russian conversion of the ex-TFC Yak-11 that languished in the storage yard out the back of Planes of Fame at Chino for a while after its arrival from the UK?

And we have a winner!!

There is no scoop on the top because the carb. air is supplied from the wing root. Like a Bearcat with a 2800-CB installed

Excellent. I knew I could trust yankee ingenuity to find some way to engineer around needing a scoop on top of an Allison.

If this is the ex TFC one (built alongside OFMC's) the scoop arrangement was sorted out in Russia, I recall having a conversation with the late Mark Hanna about is some years ago whilst they were overcoming the issues, he really didn't want to have a scoop on the top of the cowling as the others had.

Aha, russkie ingenuity -- only thing better than yankee ingenuity!

More like "trolling" if you ask me.

We're interested to see how much manifold pressure we'll get when we fly it.

I never did quite understand the fact that, although European operators have managed to cope with the quirkiness of the Russian systems (compressed air for everything - engine start, flaps, brakes, gear retraction) perfectly well for over 30 years, US restorers seem to feel the need to 'Americanize' everything about the Yak C-11.

Because, if you want to fly your aircraft and maintain it, you need parts availability. That is why most U.S. operator's "Americanize" them. If you flew them or worked on them, you would understand.

We managed to restore and operate 2 very successfully in the UK for a good number of years, both aircraft are still flying, 1 in the UK (first flew 18 years ago after restoration) and one in Germany, both are stock aircraft.

Well, good for you. I see you are in Europe. As I said, parts availability is the key. In Europe, you may have a better time of finding brakes and tires for the Yak. Over here they are nonexistant. If you fly the a/c frequently, you need spare parts availabliity.

I'm sure warbird51 is making a valid point. My hat is off to US operators who go the extra mile and source the stock parts, whether from Europe or wherever. And it's unfortunate that none of them is doing that with an -11 at the moment -- in fact, I haven't seen a stock Yak-11 fly in the US since G-AYAK in 1982. But I realize not all owners are made of money, and they still want to fly their planes.

Certainly looks nice. I don't see ducting for an air scoop on top? Wonder if this will be the first ersatz Yak not marred by a scoop up there. I never tire of seeing these, although I do wish there were still some stock Yak-11s around.

August

Maybe not the first, I don't see a scoop on the one in this thread.

Another cause of the difference is that the UK's CAA won't let you make substantial mods to a type - or fly 'Experimental' or equivalents, IIRC, - so it's as is or not at all. More detail welcome from those who have to deal with it!

Is the back lower part of the fuselage covered with fabric??

Thanks

Yak 11 yes. Yak 3/9 metal over tube frame, IIRC.

Cool; I don't see one either. Although I know there are a few out there with flush NACA type intakes that would be hard to see from that angle.

Roger that and thanks.....
