The P61 is a real peach..would love to see one fly..
There's a decent video clip of the newly completed Fw190 that flew recently; with a Russian Asch 82 "T" / 14 cylinders, 42 ltrs, 1900 hp direct fuel injected engine, very close in size, shape and performance to the BMW801.
There were still some landing gear retraction components that hadn't been installed yet..so the gear wasn't retracted on this flight..still a very impressive video..well worth the download.
