Ok Dan, I'll bite again. Those Darts guzzle roughly 1250 litres an hour, on fuel burn alone you can run 2 king airs.
But heh, don't let me stop you.
You posted here for advise, but as soon as someone here posts something you don't like, you will ignore it anyways.
As an aside, who cares how tall the guys are, they will only stand up for 30 seconds to get into their seat on the way out and another 30 seconds when they get there.
You want to buy a 38t aircraft with 2200shp Darts, to run a few employees back and forth on a 450nm trip? Go right ahead, it's your money. Overhauling 2 of those Darts will set you back the same as buying a midtime BE200.
Keep dreaming, Dan, it sure is entertaining for us professionals.
