Default RE: modification to a Sig SE

Nothing against a pull-pull rudder--install one if you like. It's just that, unlike most kits, every detail of the SSE controls have already been worked out and designed into the kit, and it seemed a waste not to use it.

Check out the build tips in the [link=http://www.rcuniverse.com/product_guide/kitprofile.cfm?kit_id=226]User Review section[/link]. Not a lot of detail on the bolt-on wings, but here's what I did:

1) Before sheeting the wing, I epoxied a 3/8" thick maple block (1" square) to the inside of each ply root rib (the inner root rib), directly ahead of the small hook hole. (You could also epoxy it right over the hole, but I wanted to leave it open in case I ever wanted to use the hook-and-rubber-band joiner in the future).

2) After doubling the fuse sides, but before framing the fuse, I filled in the opening in the fuse doublers near the hook holes with 1/8" balsa (1-1/4" wide), then added a 1/8" lite ply tripler (same width) over that, from the top of the fuse down to the landing gear block (bonus: extra reinforcement for the LG).

3) I then aligned each fuse half over each wing panel (with the cadboard tube, aluminum wing tube, and balsa dowel in place), and drilled a 3/32" hole through the tripler, doubler, fuse side, wing root ribs, and center of the maple block that I epoxied earlier. I separated the fuse side from the wing, enlarged the hole in the fuse to 1/4", and tapped the hole in the root rib/maple block for a 1/4" nylon bolt.

This worked well enough, and my only complaint is that the fuselage is so narrow you can't fit even a stubby screwdriver inside to tighten the wing bolts. So you can go with hex-head bolts, or build your own super stubby screwdriver (which is what I did) out of 1/16" piano wire.

Looking forward to the build thread. Also check out kiswa's thread in the Beginner forum--very long, with probably way more information about the posters than you wanted to know, but some helpful info as well.
