The Glasair and Pipe Dream shared the same wings and two joiners per wing panel were used. I elected not to use the joiners in my build which ended up being a mistake. I used 1/8" aircraft plywood spars that overlaped the fuselage former however I didn't account for the drag forces. As i leaned out the engine and speed increased the right wing panel failed. I have another fuselage and most of the parts to build another, just need a set of windows, wish I could find a set.
