I little progress with the right aileron hinge problem. I cut through the old hinges using a hacksaw blade (since I had to cut through the metal hinge pins). Then I did my best to drill out the old hinges. This wasn't easy, but eventually I managed. I epoxied medium Robart-style hinges into the aileron LE. But these didn't line up well with the holes in the wing TE. So....I enlarged the holes in the TE to 12mm and then packed in a 1" length of 15mm balsa dowel. It made for a very good, tight fit. These were CA'ed in place. Next I remarked the horizontal centerline on all of the dowel plugs, then taped the aileron in place and marked the vertical position of the hinges. They were all within the width of the balsa plug though not all were centered.Still ahead, I need to drill out a 3mm hole with maybe a shallow 5mm "pocket" at the top. Finally, I'll re-grease the actual hinge "knuckle" and re-epoxy the aileron in place...using 30min epoxy so I have plenty of time to take it slow and make sure everything is right. I don't want to have to do this again!
