As long as the modeller knows what he's doing, it won't be a problem. It's really very easy. Just a matter of breaking the wing up into proper sections (AND flight controls, this get's a bit tedious). You have to not only do lots of PIVOT editing in Max to get things exact, then you get to go into the data.ini file and properly call out everything so the game makes it animate.
The end result is very satisfying though and is worth the effort.
For the Prowler's wings I had to animate 4 speedbrakes, 4 spoilers, 4 slats, 4 flaps, and two ailerons, and then do the wing folding and hope that it would all work!! I'm very glad this sim is capable of all this stuff.
Great fun. :D
