Framed up first of four wing panels.
A little head scratching over control means - sketches circled in red show what I thought would have been pretty cool - servo output shaft direct drive but, ultimately, decided to go with conventional pushrod linkages to a control horn.
Drew up control horns based on a 1/4" travel at the servo output arm. Small circle represents servo travel arc for inner most hole; large circle represents flying control surface arc - radius determined by 1/4" travel for 5 degrees of travel up and down. Figured tangent line between the two circles should provide symmetry for equal movement in both directions hence the reason for the "leaning" control horn design. Since this is a full flying surface design, have some concern over having too much control throw now even at 5 degrees and can't decrease it at present control horn length (I can go in [increasing throw] but I can't go out) unless I add an extension. Keep trying to justify the decision in that aircraft design is a compromise of components and probably need more throw for the auto-rotation mode anyway...
Xerox copied my drawing, cut out the horn sketch and 3M77'd it to a stack of four .035" G-10 blanks. Drilled holes, pinned, cut, and sanded to shape for four identical control horns. Horn size ends up being about 1 3/8" center to center.
