Much progress on the wing here, though I've been hung fire for a tidy and effective way to attach and detach the wing tips. The spar is sufficiently strong, but too narrow to run a screw or pin through to retain it. So after much pondering while sanding laser burn off parts, I arrived at this solution: Reinforce the mating ribs with ply, bend a "staple" of piano wire just a tad narrower than the thickness then notch the ply to host the staple with a mini hacksaw blade. This way I could sneak up on the ideal thickness with gentle swipes of the saw blade. I bent both staples identically so they are interchangeable THEN adjusted the slots. The fit is snug and feels very secure. I will probably put a square of scotch tape on it when flying, but I doubt it will come loose in any case.

The wind here is terrible today after an absolutely glorious Saturday that was calm enough to fly peanuts at high noon. I actually flew the Wee Willy at noon over a local apple orchard. She flew wonderfully, but this was not my first attempt; for balance, that plane needs to ride 2-3 degrees nose down on the spar or it's tip stall city. My advice with this or any lofty, heavy dihedral slow flyer is start nose heavy and back it off on subsequent flights as needed. If you start level or tail heavy, there possibly will not be any subsequent flights, but you may eventually get your nose weight via repair glue. I can't wait to get this one wrapped up! Of course there is a cat.
