I downloaded it and tried it out.
Major problem:
FS9 claims ylf50_overhead.gau is not compatible. You can fly without it, but...
Moderate problem:
Aircraft is very squirrely on takeoff until you get enough speed for the vertical stabilizer to actually stabilize. Of course, shortly past this point, you can rotate...and then it behaves nicely.
Minor problems:
No dynamic shine on metal surfaces from spot view.
No pilot(s) in cockpit from spot view.
On the plus side, the sound is excellent and the weather radar in the panel is a very nice feature.
Over all, if you want a fast corporate jet (I can't believe they put 3 engines on that sized plane) that does most things well and can overlook the problems I noted, it is a good plane.
