So here's the story.
A very generous and talented long time Aerofly content creator (all the way from the FS1 days) named krzysk is in the process of converting an extensive library of aircraft to FS2.
Be aware, these planes are in various stages of completion, from rough alpha to beta, and he has hosted them to github for users to try while he continues to work on them. Updates can be as often as every few hours, so be sure to check back often for the latest version!
Downloading is simple: Download, unzip, and place the unzipped folder into the appropriate Aerofly aircraft folder. Be aware that the unzipped folder will have the Suffix -Master, which will need to be removed before the plane will appear correctly within Aerofly's aircraft selection screen.
The currently available planes can be found here: https://github.com/krzysk1?tab=repositories
