EObrad,

If you've already got it together, with wood glue, don't sweat it. Just lay fiberglas tape (the 3"wide stuff)along the wing joint and attach it with CA.

I saw a guy fly his Corvette (it's a local plane, long & slender, 65" wingspan or so) with a .61SF for quite a while, sell it to our friend, who flew it another 200 flights or so. One day said friend was practicing rolling circles and a wing came off, fluttered down while the rest of the plane augured in, etc.

We inspected the remains, and determined that the wing had no joiner. No ply joiner running from one wing into the other. None. It was joined at the mid ribs, and fiberglassed. Well over 200 documented flights, with the only thing holding the wing halves together being the 'glas tape & CA. All that load was absorbed by the sheeting in the middle. Now, a spar joiner would have been better, but it lasted a couple hundred flights.

On the other hand... if you don't have it together yet... spend the $5 and get some epoxy.

Good luck,
Dave Olson
