Why can't I see the wing joiner spar in any off the pictures a good glue joint is 20 times stronger then the wood itself yet it appears to have pulled out not broken off
that could explain the failure
maybe I can't see enough in the pictures do you have one of the side looking into the wing
As far as glassing well there are plenty of 25- 40% planes that have 2 piece wings butted to the fuse on the tube spar and they do violent manuvers with no problem so I'd say myth busted
