I used a freeware Dornier 228 to illustrate an article on Lukla. (I think we even put it on the cover CD)
I used a freeware Dash 7 to illustrate an article on Courchevel. (I think we even put it on the cover CD)
I used a freeware T-45 and freeware F-14 to illustrate an article on the Nimitz.
I could have sought out payware to do those articles, but the quality of the freeware was such that it made sense, was a service to the readers, and gave a nod to some fantastically talented freeware developers.
Simply put - if you make it, they will come. None of the above were modeled to anything other than light systems modeling, proving that a good 3D model with a basic rendition of the cockpit will work.
