I operated a CDG-LAX leg last night with the UA model (a bit of nostalgia - I was on this flight for real almost two years ago).
What a beautiful aircraft
I can't believe the detail (especially the articulated main undercarriage), and I still get good framerates
The aircraft is a real challenge to stabalise with a full load of fuel once you are initially airborne. I don't know if it is more realistic or not, but it sure is more challenging.
P.S. For something real freaky - the gate that I was instructed to taxi to once I exited the runway at LAX was the same gate that we used on my real flight two years ago
(twilight zone music plays in the background).
