This is a modification to the standard kit but it’s the way I like to do ailerons. First the aileron linkage is made from heavy 1/8” spring steel. There is a brass tube around the wire inside the wing for a bearing. I wanted the ailerons to be 1.5” wide. The wing marked for the width of the aileron plus 1/16”. I use a 3’ long straight edge and an X-acto to cut of the trailing edge of the wing. Do one wing at a time so the parts do not get mixed up. The back of the wing is sanded smooth and a 1/16” sheet of balsa is glued to wing and sanded to the wing contour. The aileron is cut off the trailing edge piece. The remaining piece becomes the part that goes over the linkage. This piece must have 1/16” cut off of the front part and the foam hollowed out for the linkage. The brass bearing of the linkage is glued to the back of the wing with epoxy and then the trailing edge is glued back on the wing. Next the leading edge of the aileron is cut off ¼” plus a little more for the hinge line. A ¼” balsa strip is glued to the front of the aileron. The aileron is trimmed for 1/16” end caps and an end cap added to the end of the center section. Sounds complicated but it’s pretty simple after you work through the process. The aileron is very light but very ridged. See the attached images for detail.
