that is a mix of FSX freeware and payware but mostly freeware. These at least these are not labeled FS2004/FSX I could add to the list if I included those.

and that is with a couple of hours or so of looking. and I noticed that the list of Kansas fields has grown since I put this list together, it is hard to keep on top of these. of course, that is a good problem to have.

and I skipped a lot of international scenery and paid attention to NA and Caribbean.

it looks to me like there is plenty of GA airport scenery for FSX available, with searching. for instance OrbX has a huge amount of GA for Australia, there are German and  UK airfields, etc.

so there is a lot out there if you search. you just are not going to find what you looking for by staying on a single site and expecting it to come to you, the Flight Sim community is way too dispersed now.

have fun flying!
