All I accomplished today in five hours was to attach the nutplates for the flap hinge mounts, then attach the aileron hinges, including fixing the nutplates. This would have gone a bit faster, but my right angle drill attachment only takes hex bits, and my #40 drill bits are either jobbers or 1/4-28. I had another 90 degree angle attachment, but it bit the dust a while ago, and I haven't replaced it. So I improvised with a nut driver and the 1/4-28 bit. Somewhat slow, but it worked. Now on to fitting the upper aileron skin.
