Mjolnir_Zero: Don't know if you've already moved on past this and figured it out, but heres my take on it.
JO420: Theres a couple of ways I'd approach it. (sorry maya terminology haven't gotten back into max enough yet, but it should be similar.)
First I'd model it flat and then group the pieces rotate the wing to the right angle to meet the body, then throw a bend modifier on it and set the low bound to 0 set the curvature to 1 and move the bend modifier to the right spot to where the wing bends. Adjust the high bound to like .25 or so so that it only bends the section of the wing that is actually bent, and then adjust the curvature so that its bent to the correct angle.
If that doesn't work then maybe this approach I use for pipe bends?
Model it flat and then cut it at the red lines, rotate/move the larger pieces to the appropriate spots then bend the cut section with a bend modifier and vert weld it back together. It can be a hassle the first couple of times you do it but its really fast once you get the process down.
