Yea, I have seen the control horn trick. I have considered it, but the design is for a duration sailplane with a six foot wingspan with a seven inch chord (so far). I am trying to keep everything inside the wing to reduce drag, look cooler/cleaner and prove that my brain is capable of complex problem solving. I am OK with there being exposed wire or linkages with the flaps down, but I really want to end up with a clean look when everythign is closed.

I bought a sheet of 3/16" ply to make some templates for gang sanding the ribs on my Diamant today and figured I could use the rest to make a few testing models.
