Hello Greg,
Sorry to bother you. I am a beginner to "Orbiter" - and I am also a big fan of the X-15. I see that you have made several Add-Ons re the X-15 Delta in the Orbit Hangar Mods. I am using the latest version of Orbiter (100830). Would your X-15 Delta be compatible ? And which is the right Add-on pack to download? I would appreciate any advice you can give me. BTW I have done a search on "X-15" in the Orbiter Forum, but it shows no results at all - which I find suprising.
All the best,
Paul Conti
