Here is my problem.

The cabin of the Zephyrus is almost totally glazed on the sides and top offering little in the way of strength.

The wing leading edge is raked back almost to the spar.

My first idea was to fit a mechanical locking system halfway along the root rib, but with the weight of the wings it just bowed the root ribs on the fuselage and would have pulled it apart on a landing

I then resorted to non scale and visible rubber bands across the fuselage which I would later box in and although they held the wing, the leading edge had a tendency to open up by the wing swivelling on the struts. Maybe the gap is made worse by the fact the hooks are behind the line of the strut

I think I should go back to a mechanical connection, but I am reluctant to secure the wing to the fuselage. One idea is to pin the outer ends of the wing joiners through the wing using nylon bolts tying both wings together, but I am open to suggestions on this one

Vince,
maybe you could use a 3mm steel rod with both ends bended 90 degree. This steel rod should be reach from one wing half to the other inside the fuse.
I would make steel connectors like the original has at the main spar that goes into the fuse area between the wings. Into these connectors you could press the steel rod and secure this with a screw, that the steel rod can't be remove by vibration or and move.
Hope that my english could explain what I mean.
