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

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.

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....

My regards,

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:)

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