hey Dave,
concerning the wing mount on the front end, its basically is what i would call a HE and SHE half moon, the former on the Fuse has the outer line shape of a half moon and on the wing you put the half moon that came in the wood parts bag, the piece that go on the wing has the same outer shape as the inner line on the former on the fuse so these mate perfect. what the manual tell you to do is place the wing on the fuse and then from the canopy access area mark exactly where the half moon on the wing would go and tact or glue it on the wing, after you remove the wing the you could put 2 small size bolts to help hold the half moon on to the wing so you can get a tight fit. it works nice and keeps the wing tight up against the fuse.
