Sorry, by "missing flaps" I ment I have the rudder, two elevator, and two ailerons sections. I do not have the actual flaps, although it appears that the original kit was set up for them but the person who had it before me covered over the holes in the wing (where the pushrod for the flaps would go) with fiberlgass patches. I cut those holes open again, and that revealed the weave i think you're seeing. I looked over it closely again just now, and that's the only fiberglass I can find. The rest is definately wood, I would assume balsa, possibly with some epoxy over it (but I'm not sure).
And sorry for the poor photography (and spelling

) skills
