Bump to update
I think it's time to update this thread.
CitationMax has a video on YT in which he demonstrates FL410 in 15' with 5 adult POB.
I know a Lear 23/24/25 can do that in 12' but still is impressive.
I've been told Latitude and Longitude can climb at 6000 FPM. I wonder what's their time to climb.
