But wouldn't this > effect the washout with a lot of movement in them? >>>>>>>>>>>>>>>>>
I was surprised that they were called flimsy - particularly after the web was added - this should become a (relatively) sturdy structure. Alook at the WAF's gives some indication of the load that they were designed to bear. I was more surprised at the coment that they were there for fore /aft support - they are even weaker in this direction. I think they are perfectly adequate for the portion of the load (vertical) delegated to their location (.75c) if they are built to plane with the correct materials and adhesive. The rotational (torsional) forces are in the shear capacity of the skin - very important to consider when adding /changing flap or aileron sizes or proportions that differ from the design and impose different "twisting" forces to the wing. ___________________________________________________________ ALL-NEW Yahoo!
