I have a lot to learn but using the demo is extremely frustrating since it stops functioning after several minutes so I can't get a good feel for the product. Some planes are labeled as XP8 or 9 or 10 but not sure if they will install correctly and run well on XP11. Some do not have 2D and 3D cockpits and that makes viewing real frustrating. I am still questioning what is available for free since I have been looking around on this forum for aircraft and what I have downloaded has been less than stellar as far as quality and details. How far back in versions can I import X-Plane files into the new version 11?
