Well, I got to spend some time on it this weekend. I put in the new cap strips and servo mount, then cored the wing. Everything went smoothly. Gluing was done with Sig-ment for wood to wood and Gorilla Glue for wood/foam to foam. I made a new servo mount that should be a bit more suited to the job. The cap plate that runs from the center spar to the TE spar is 3/32 basswood. A 3/32 birch ply doubler comes next. The ply doubler doesn't run the entire plate, only around the servo opening to provide extra strength and something for the mounting screws to bite into. Finally, 3/8" balsa surrounds the servo opening to give more surface area for gluing to the surrounding foam as well as further material for the servo screws. You can see a comparison of the original and new mounts in the picture. The new mount is 1/4 oz heavier than the old. The original servo opening in the wing core had been somewhat roughly enlarge. I evened up the sides with the hot wire cutter and then cut a plug to cover it.

I test fit the aileron servo in its new home and I'm rather happy with the results. Unfortunately, after all that, the wing weighs exactly the same as when I started. Not that I consider it completely wasted. I am much more comfortable with the structural integrity of the wing now.
