the LE hook and TE screws work on any size bird. I built a 96" spook and she ran for years, wings split in the middle with a music wire/brass tub connector.
She was a big ol girl, and this was the only way to transport the big wig....I did a million loops, and the power plant was a Maloney 125!!! Grin

Here's one I did but instead of hooks, I simply glued dowels to the ribs at an angle. They bottomed out at the point where the wing was to stay. I used magnets to attach the trailing edge. Screws would work just fine and probly weigh less. This bird has a 50 some odd inch span so the extra gram or 2 wont mean much.

If you look at the picture closely, you will see where the dowels go under the window frame, and fit snugly into the corners of the window/cabin framing.  They locate both forward placement and side to side placement.
VERY simple and lite.

Once again, I have to thank my friends for this idea, I did not think of it myself.

Sorry about my poor drawing. I blame Tom for this because he constantly inspires me to try new things and learn stuff. Grin Cool 

If you have a center rib, you can use only one hook. I prefer to use two because it seems to sturdy up the wing location. 
If you don't want to, or cant, use the upper cabin top windshield brace, you can install a dummy cross brace any where you wish. I have seen some pretty LARGE/HEAVY DUTY crossbrace/hook setups used and by placing the whole thing in the center of the wing, they are almost invisible thru the cabin window.

On heavy birds, you can taper the rear of the hook away from the cross brace to get more attachment point on the rib, and strengthen the rib.

In extreme cases, a duplicate rib can be made and added inside the center section of the wing. This duplicate can be made of thin ply and the hook becomes a slot hanging below it. In that particular case, the extra ribs featured two slots each and that made a total of 4 hooks. Then 2 countersunk allen head screws were used under the wing, thru the top cabin wall, and into blind nuts mounted in the false rib/hook plate, to lock it all together.

Special thanks to Tom Akery for this fine offering; 

One way is to install a "Key" or "Locator pin" in the front of the wing. This plugs into a hole in the former on the fuselage.  Both holes were drilled at the same time while in proper placement ensuring alignment. Then the screw or the magnets are placed opposite the "key"/pin to anchor the wing in place.

Here's a picture of the Goose's wing showing the "key"/pin.
