I applied the glue the cores because of the perforation job. My thinking was less surface area, less glue. Didn't work out...live and learn.

I got most of your other points covered. I did use a 1/2" wide .070 CF laminate 'spar' top and bottom to carry the load beyond the end wing tube rib.

Next wing I'll stop playing and do it right! Thanks for sharing your ideas.

Edit: That should be .007 CF laminate.
