This is always a favourite topic that comes up on the boards. Flaps only, flaps plus ailerons, flaperons, flaps with just spoilers?
I am far from an expert on the matter, but I always was never quite sure how to interperet the scene from the DYRL video game (for Sega Saturn) that shows Hikaru warming up his VF and then taking off from the Prometheus on earth.
(excuse any incorrect labeling on this pic, due to not knowing what surfaces are really called)
It shows what appear to be independent inner and outer control surfaces. Inner ones being flaps, outer ones being what appear to be ailerons/spoilers? Those outer surfaces are seen moving both up AND down while the inner surfaces remain at rest. The outer surfaces on each wing are seen moving independently, opposite each other, AND in unison (as in both can be up, both can be down, one can be up and the other can be down).
The inner surfaces are seen extending fully for takeoff along with the leading edge, while the outer surfaces of both wings move down with the inner surfaces for takeoff. Also noted are that the bottom of the outer surfaces appear to be red (like the bottom of the F-14's spoilers) as you see them when they are up (which makes me wonder when we make models or customs, should we be painting the bottom of our outter wing surfaces red?), and the extended portion of the inner surfaces are also red on top (but you don't see it until it extends).
I've always loved this little bit of animation, but I never really knew how much (if any) liberty the animators took with Kawamori's official design. Since it is probably the latest animation of the VF-1 in action (not counting the cameo VF-1's in M7 or MPlus), and it is NOT a product of Anime Friend, lol, I suspect Kawamori may have at least been aware of the animation before it got okayed?
Anyway, that scene is my favourite interperetation of whole "how do the VF-1 wing control surfaces work?" What is the official word on it though? I am always troubled whenever I hear that the entire trailing edge is only suppossed to move down only.
p.s. Also note the 3 spoiler sections shown on the 1/48 Ultimate model ( on the top side of the wing, directly in front of the trailing edge control surfaces) do not seem to be depicted in this footage.
