Coming along nicely but looks on the complicated side. For 3 out of my 4 FS planes, down and welded were the answer! I ended up installing the 1/4" square carbon fiber rods for wing stiffeners. I cut a channel with my Dremel tool and then epoxied the rods in place. I did my best to install around the CG per your suggestion and I still am hopeful that my "aerobatics" won't be as stressful as yours. I also sanded a bevel into my ailerons and will install (temporarily) my Robart hinge points.
Waiting for the next installment of pictures as I am getting anxious to move on.
