Hope you are doing well,
I just saw your amazing job on a Honda Jet, Cool!
I'm a bizjet enthusiast buddy, When is your release date? I can't wait for testing this bird.
Go for Challenger 650 after this fabulous job. (or) work on a Light Sport one, like Aeroprakt A22 LS ;-)
First Start fs and then start ADE. Link them in ADE. Go to fs and slew to the spot where you want your airport to be. Then hit shift z, it will tell you the Alt you are at. Type that in with your new airport specs. Build Your Airport, when you are done use ADE to make polygon around your airport. set it for flatten terrain and no autogen scenery.
