X-Plane has the 747-400, but from the issues I listed above, I'd definitely prefer others. I recently bought a DC-10 for FSX, but FSX has had some stability issues recently for me, I may have fixed them, haven't confirmed, and I want to know before I start doing transatlantic flights with a DC-10-30. I want to get some long haulers for X-Plane as MSFS, I don't trust all to much, last time I did a long haul from London Heathrow to San Francisco in the 747, 7 hours in, it crashed. The default 747 has some definite kinks to it.
