Look for Wings of Power, they did an FS9 pack which includes some great ones. There was also a payware and a freeware Me-262 for FS9 as well. I think the freeware one was at Flightsim.com

Thanks for the info.
Couldn't find that particular WoP pack (I have their B-17, which is excellent).
The only payware 262 I can find is for FSX.
Found one freeware at Flightsim that I haven't seen before (odd, since I've been a member there for years); created in 2007. It is nice visually, with a photo 2D panel, but has major trim problems (fixed with aircraft.cfg edit and addition of a simplistic AP), fuel gauges don't work (replaced), no ADF gauge (though you're given a nicely done period ADF receiver; added a gauge), and no VC at all (can't do anything about that). I'm using this one now, but still looking.
(And the only Ar-234 I've found dates to CFS1 days)
