Art,

Welcome! And thank you for these aircraft. Adding a file to the download section is easy.
First, click on the download tab at the top of the page. Then, under "navigation" you see
the "Add" tab. Click that, and it will take you to a page where you can upload your file(s).

Shortly after, one of the admin/mod types will usually approve it to be added to the system.

Easy enough!
