Terry,
See if you can find the construction article and plans for Paul Walker's original Impact. Paul used a fairly simple approach with the wing bolting into the fuse, the stab/elevator bolting in and the rudder bolting down. I used this on a Magnum and it works very well, just align things as you go and bolt stuff together before you glue it in place. This keeps things align and it reliably goes back in place and holds alignment when you reassemble.
Best, DennisT
