I'm in the final stages of reassembling a once-flying Skybolt, built 1984. There is a good chance some of you know the airplane, it's been rebuilt a couple times now, the latest one because of some damage in transport.
1. I have access to a set of plans for it, and in the plans I don't see any twist built into the wings. With rigging sticks, there appears to be about 2-3 degrees of twist from the center section to just outboard of the I-Beams. I cranked down on the flying wires a little, but I don't see them getting much straighter than it is right now without some major changes. Anyone else seen twist in the upper wing like that? It almost looks like it was built that way, since both sides exhibit the same thing, and it's twisted in a way that would give aileron authority further into the stall... when the blue side is up.
2. On the flying wires, there doesn't seem to be any kind of safety on the nuts, just plain nuts. Is that normal? I would've thought they would use Nylocks at least, or double nutted them.
3. On the bottom wing, with the aircraft leveled side to side (based on the fuselage tubes in the aft cockpit), it appears the right wing has about 2.2° of dihedral, and the left wing has 1.8°. Where is a good place to measure dihedral from, and is there a way to correct that? The owner isn't super concerned about it, but I'd like to get it as perfect as I can as a place to start.
