I can't download FSDream Team GSX.
It is possible to download the FSDreamTeam GSX from the official website. They have an installer hosted on the MediaFire servers and it's approximately 200 MB and requires FSX or P3D V4 to work properly.
You can get the link from the following page, but it requires purchasing as it's not a free product: https://www.fsdreamteam.com/products_gsx.html
Tam można ściągnąc tylko 627 kb. Instalator z tego co wiem ma 40 MG
