After almost two months of inactivity, I have some shop time. The wing tips are installed and shaped. the right side is hollow to help compensate for the weight of the side mounted engine. The less it weighs, the less weight will have to be added to the other side to achieve correct lateral balance. I will post some pics when I get my camera cord home.
Next on the list is mounting the aileron servos. I am using one servo per wing IAW modern practice. Time to fire up the AutoCad, and design some servo mountings. Rather than just hack into my vintage wings, I designed the mounting box(es), servo cutout, and the servo layout for the correct linkage geometry. Everything will turn out correctly the first time, and the pieces will fit properly. The results can be seen in the accompanying pic.
