Aaand here she goes.
I don't know what else to say. Except that she haz a neat amount of bodygroups, including this wing. It has 19 bones (!) each in closed and opened state. I should warn you that this wing is kinda "raw", so if there are clipping problems with them - don't be surprised.
I will update it to v5 later, for now I need it to work in GMod. I hope it works there. It should.
