Hi,
Just one more observation, are you actually gluing the two wing halves together as the brace is just that a brace to reinforce the joint. The joint along the two root ribs looks very cleanly broken if it was glued.

Hi,
I would suggest that you use some good quality 3mm hard ply / Birch ply and make the joiner full depth or perhaps 1mm less. To install simply cut slot out of both top and bottom skins and using saw remove just enough of the ribs to allow it slot in. Glue to both top and bottom spars and leave a slight gap at the top and bottom which can then be capped with balsa and sanded back. Also ensure that the grain is running along the brace which is normally the direction that provides most strength, from your photo it looks like the grain was vertical in the joiner that you made. To spread the load at the joint between the two wing halves onto the skins you could also use some 50mm wide white bandage and lay across the joint between the two wing halves it can be glued down using white glue rubbed in. This would reinforce the but joint at the wing root.

Hope this helps

Joe
