You have to download the color scheme in addition to the model. You can only download models that use the add-on versions that you have. You can also download flying fields but there again, you will need the proper add ons. This is indicated on the site.

They show up in my plane selection menu when I download them. You can use the new color scheme on your on edited model that is the same as what the color scheme was originally based on.

Not all the download stuff is that desireable. I try them and if they don't work out, I blow them away.

Enjoy,
