I can see that I used a 1/4-20 bolt from the fuselage inside through the wing end plate. The other photos of the Saturn with the Supertigre are of one of the prototypes I flew in team selection.

Hey Ron,

Do you know of any Pattern friendly clubs or places to fly around Port Orange?

As Ron sez, a rubber band is fine to hold the wings in place. Most of the load is on the tube. The plastic bolts are overkill but are also light and easy to thread. I tested strength of one 1/4-20 bolt many years ago now. It held about 75 lbs to initial yield point and never did break clean as I recall. It simply stretched to about 110 lbs pull when I stopped the tensile test.
