I'm going to do my best to keep this first post updated until we can get a proper download page.
Remember that you have to download the file, unzip and put them at "C:\Program Files\1C Game Studios\IL-2\data\graphics\skins\[AIRCRAFT VERSION]", all of them. File path may be a bit different on your own computer but ...data\graphics\skins is where you need to go.
