There is a big difference between a ground run in a museum and an engine, which is doing it´s job and bringing an aircraft and it´ s crew in the air. Also there are some storys, that some of these engines have been badly damaged or at least seized during those ground runs.
EDIT: I just finished watching the video (above post) the attention to detail they are giving is just mind boggling, personally I can't wait to see the FW189 when it's time comes for releasing a similar video. Well done all.....:cool:
Yes, good work. The VS11 prop of course uses pressure oil from the CSU/pump to operate blade pitch change. The big difference from say a Hydromatic is that instead of operating a piston and the cam slots to move the blades, the Junkers has a hydraulic operated spur-gear type motor and drive gears in the dome to move the blades. So it is not true to say that there is a pump in the hub, it is a hydraulic motor operating with oil pressure from the CSU/pump on the engine. Also, the Jumo 211 was operated after WW2. Jumo 211 engines powered many legacy aircraft in Europe after the war. Interestingly, one of those types was the Czechoslovakian S199 developed, Jumo 211 powered Bf109G, examples of which fought in the war for Israeli independence in the late 40's. I would be interested in anyones info about the last Jumo 211 in operation? Cheers

And the Jumo 213s that were manufactured in France and flown in Nord seaplanes into the 1950s, and a few new engines put together with Jumo components. From the video on just the VS11 prop and from the pictures it looks like they had an entirely new prop and hub manufactured or copied from an original. From a quick glance it looks like the IAF last flew the S-199 in 1948 and the Czechoslovakians last flew them in 1957. It seems possible that the planes could have remained in legacy trainer roles after that also.
Hi Dora9, Yes, I can imagine the Czechs were the last operators of the 211, unless someone knows better? I am surprised if that Hub is new made? There must be quite a few that are usable. Anyway, I guess the Vintage V12 Jumo 211 has run?

I read in one discussion that Vintage may begin testing of the 211 this month. I would be curious how long France operated their version of the Jumo 213. The last Nord 1400 seaplane was delivered into service in 1956 and in theory could have operated for a few years, maybe into the 1960s unless they were quickly phased out.

FHC shared a very nice photo of the the new Stuka propeller that was prepared by Skycraft Services, Ltd., UK.

Didn't the RAFM Stuka have its engine run at St Athan?
