Right Wing aileron hinge

Drilled holes through the right wing ribs for attachment of the aileron hinges.  Made a mistake on one bracket as the two halves of the hinges did not line up perfectly when drilling, so created oblong holes on one of the hinge plates.  We fixed this by making a new aluminum hinge bracket from 0.063 aluminum.  The manual says to simply swing one bracket plate out of the way before drilling, but that's not as simple as it sounds with everything attached and clamped in place.  Hours 1.5
