A couple of shots of the lower wing saddle. The instructions amount to make a box, glue it in, sand to match the fuselage contours. So far I haven't found any mention of wing alignment or incidence. The marks on the saddle parts are to help me keep them square. At this point I am going to deviate from the manual and build the wings and tail. This way I can align the supporting structure for the wing and tail before I lock them down and sheet the front half of the fuselage. The alignment of the top wing is set by the top of the fuselage. Once that is true I can use the upper wing to match the incidence of the lower wing and make sure that the horizontal stabilizer is truly horizontal. The plans show a rudder-elevator-throttle model with no ailerons and about two inches of dihedral under each wing tip. A scale upper wing would be built flat with no dihedral. Since my model will have ailerons I am going to have a flat upper wing and reduce the lower wing dihedral to about to about 1/2 inch at the wing tips. I will also modify the center sections for bolt on wings.
