Wing pulled away from fuse
Have a D&L designed 26 % Edge 540 I built. Smoothest plane I've ever flown. The design has the wings supported by an aluminum tube, with 3 dowels on each side and held together with elastic bands to hooks on each wing half. I was concerned about the elastics method as were some of my flying buddies, but that's the design and it worked great flying precision aerobatics.
Then I began doing 3 D, torque rolls, waterfalls, harriers, lomcevaks and blenders. Everything seemed fine, so I did another lomcevak and suddenly the right wing pulled away from the fuse and turned 90 degerees; plane went into an ucontrollable spin into terra firma. Luckily it is repairable, but would like suggestions as to alternate ways of securing wing and also to warn anyone with this design about this problem.

I would do as Stick Jammer suggested. Or, instead of using rubber bands you could use zip-ties to keep the wings together. Good luck!

I use springs. Check out the spring selection at your local hardware (Ace, True-Value, etc) and you will find some very stiff and strong springs.
Works for me.

Shucks, I took the bolts out of my 33% Extra and installed hooks. I use small bungies, you can get 4 to a pack at WalMart, I do every thing in the book and some things you can't put in a book and my wings stay on.

for my foam wings, i sink 6-8 inches of 1/4-20 nylon all thread (fully threaded rod) into the wing and glue it with 30 min epoxy. the use a piece of 1/4 inch lite ply on the inside of the fuse, and secure with a wing nut and cotter pin.
for built up wings, use a piece of 1/4 inch a/c ply on the inside (side towards the wing tip) of the wing and attach a blind nut (#6 or #8), then attach a piece of 1/4 inch lite ply on the inside of the fuse. then just bolt the wings on.
depending on plane size i would use one or two bolts per wing.
