I had a chance earlier this year to examine and fly a built airplane with some neat mods, some of which I'm adopting. One of the hardest parts of getting the wings on and off is hooking up the flaps. The dropped fasteners I fished out of the leading edges of the wings once they were off attest to that. John Monnet used pins and clips on the prototypes, see the videos, for both the front and rear spars and the flaps, and I'm doing the same. The built airplane I looked out had the two front lightening holes joined into one, to make access from the fuselage into the wing much easier, and I've done the same. There is ANOTHER rib VERY close outboard of the root rib, and I flanged the openings I enlarged to keep the local stiffness needed to maintain the airfoil shape and the structural stiffness in this area for flight loads.
