Rick, the Paine Field scenery is default part of the ORBX Pacific Northwest scenery. Although far from perfect, it is a rather nice representation (it doesn't have anything where the Historic Flight Foundation facilities are located, just the ramp and taxiways, but there is a hangar located at the location of the FHC hangar which does, generically, look quite the part). It does have an aerial photo scenery as the base of the airport.
And you are absolutely right about FHC's Fw 190A-5. It is the only original Fw 190 airframe flying in the world today (and extremely original at that, with something like 90%+ of the original internal structure, and even 85%+ original skins (which is just crazy, that that much remained preserved well enough to be used in the restoration)), and is powered by a BMW 801 engine, as per original. At this time, there are a couple of other original Fw 190 airframes which are also being restored to airworthy to be powered by BMW 801's - probably most noteworthy, the example known as "White 1", which was obtained by the Collings Foundation last year and remains on track to completion and flying (will likely be the next one to join the ranks of the FHC example). All of the other full-size Fw 190's you see flying today are Flugwerk replicas, and aren't really all that close to the originals, being largely 'based on' the original design, and not entirely copied from the original design - for instance, those who have tried have found that the Flugwerk parts/assemblies don't match up with original Focke-Wulf parts/assemblies, and thus cannot help in getting an original airframe completed.
I attended the Paine field aviation day, and so had access to both the Flying Heritage Center (FHC) and Historic Flight Foundation (HFF) museums, including all teh various aircraft displays which were flown in. The both aircraft are incredible. The FW I *believe* is the only 190 in the world left to be flying with an original BMW engine. (although don't quote me on that! lol). Some other note worthy aircraft which call Paine field (KPAE) home are "Impatient Virgin" (@ HFF) a fully restored P-51B with a Malcolm Hood. It has over 700 combat hours, was an ace maker, including shooting down a least one FW-190. Also, "Bad Kitty" a Fully restored F7F Tiger Cat, very rare BTW. The F7F and the F8F both performed in the demos this passed Saturday. It was amazing to see just how fast and nimble that F8F is compared to the Tiger Cat. Both sport the same engine, but the Bear Cat is known for chalks out climb to 10K Ft in 96 seconds! Paine field is home to some incredible aircraft. Great shots of these!
