In your custom skin folders, open description.lua and replace
{"texture F-16.tga f2 g0", 0, "f-16_haf", [b]false[/b]},by
{"texture F-16.tga f2 g0", 0, "f-16_haf", [b]true[/b]},or delete/comment the line, result is the same.
Could you share this UAE skin or tell where do you find it please ? I'm looking for one..
