so, i have been digging through the internet, and I have only come across 2 harrier mods. the first one made by rsvnpilot of the main DCS user files does not work at all. the second one here: http://www.lockonfiles.com/files/file/2599-flyable-harrier-stol/
works with it's external model, but as soon as you try and take control, it crashes DCS. I assume that is because it is using an old cockpit.
any chance someone with modding skills could take a look and try ti fix either of them?
