Took off a tiny bit too much with the dremel. A little shimming with some 1/32” ply got things aligned right, although I do notice a little weirdness—the piston tends to “roll” in the motor tube, allowing the control wire to move a bit right or left so that both wings can move up to 1” left or right in the locked back position. Equalizing the tension on both sides of the rubber band seems to ameliorate the problem though, and I’m guessing air pressure and drag will help keep them pinned back.
Happily no adjustment was needed in the wing’s glide position, they both deploy at an exact 90°.
As extra insurance I hardened off the wing root and control rod clamp areas of the wings with CA. The forward wing root is an especially high-stress area that I wanted to ensure wouldn’t split when the wings slam up against the fuse when they deploy.
Just need one final coat of dope to protect things from all the balsa-warping humidity here and getting the CG where it needs to be, and I think I can wrap things up.
