I moved it to Edwards AFB and did everything Boikat did. I pushed it into the desert a bit and then saved it in 'Slew' mode. Now, to launch, I just select that flight and hit 'Y' key and I'm off to the races...
I tried the author's advice and use slew again for realingment after leaving the atnosphere and it works as advertised.
I got to 600k over Edwards and made an (almost) perfect landing at LAX my first try.
Reminder: The '9' key for Nose Up is the KEYBOARD '9'. Not the Numpad one.
If anyone manages a 'coast-to-coast' or actual orbit please post here.
