Today's progress was mixed. I wasn't happy with the weighting on the aileron tab. When mounted on the wing, despite balancing per manual, the aileron seemed to want to drop to the down position. How can that be? I decided to go back to the basics. I never was satisfied with the method of hanging the aileron from wires, connected to the hinges. This is not the way the aileron mounts, of course, to the wing. So I decided to mount two aileron hinges plates to plywood blocks, cut out in a "C" shape, with an eye bolt directly above the center of the ball hinge. This really made a difference. I discovered that indeed I had way over-weighted the aileron.
That was fine, but when I set the aileron aside to clean off the workbench, it dropped, and knocked about a five inch break in the lower skin, at the leading edge. I guess if it had to happen, that's not too bad a place for it. I cut out about a one inch by five inch piece, back to good skin, to make space for a patch. Since it's on a curved area, I retrieved the right aileron skin, applied release tape to the leading edge in the corresponding broken area, and applied a 3 bid layup. Tomorrow I'll complete the patch. In the meantime, I decided to build up a bit more the upper aileron skin leading edge, to get the aileron-wing gap a bit better. Did all the prep, wetted the area with epoxy, and went to mix the micro. I thought I had plenty, but alas, the plenty I had was flox, not micro. Hopefully I can borrow some tomorrow, and repay it after my now new order comes in.
