I really didn't like the prefab tips for the flaperon just cause they felt really thin and would self destruct without much effort. But I did like the way they looked when they were installed. So I took some Hysol and lined the inside of the tip. Not pretty but it really made them feel solid when they were installed. Finished the control arm install on the left flaperon so that part was done. I started on mounting the hinge mounts on the left wing. I sandwiched a piece of aluminum between the two hinge pieces (literally a couple thousandths thinner than the washers the instructions say to mount between the mounts. Marked a line on it for the 1/8 inch space between the trailing edge and the mount and pressed it up against the washer so I could see my spacing. I clamped a three foot aluminum L to the ribs so that the back of the mount pressed against the L when the 1/8 spacing was right. That way I was certain the mount would not slip back and I would loose my space. Got both my inboard and outboard hinge mounts drilled and cleco'd with the proper spacing I measured between the hinges on the flaperon. Now I am ready to mount the flaperon to the wing and install the remaining hinge mounts.
