The 7X is a good performer...great runway numbers, MMO of .90, cruise at .85, LRC around .82, and refs below 110kts at light weights...

However, it really isn't in competition with a G550 or a GLEX/XRS etc. It wont fly the same distances and its simply smaller. I dont think its even marketed toward these planes? Most 7X owners are loyal Falcon buyers who like the operating cost of the 7X. Interestingly enough a 7X will currently cost you a few million more than either a GLEX or a G550.

It usually comes down to what the owner wants and the mission. Want the furthest range all the time? get a 550...want the most comfortable? get a GLEX....want the most efficient....get a Falcon.

and FWIW - all have been equally reliable and well supported from my experience, no matter what the various fanboy weirdos say...
