How was that gull wing joint made strong enough? just scarfed and
glued? through bolted with backing plates?

On my Zanonia wing I used 10mm square strips that were glued together
to form the spar caps. Quite interesting, because each cap strip not
only bent over at the gull wing point, but it also bent back at the
same place. I made crude bend lines with nails in my level table and
then bent the strips around the curve. Top cap strips had some 36
(10mm) strips and the lower caps had about 20. The strips were also
bent back by raising them up the apprpriate amount. Each cap was glued
together with a mixture of epoxy and a little cotton flox to give it
some body. The caps were then joined together with plywood shear webs
on both sides and vertical posts inside making a box spar on the
inboard portion that transitioned into a C section outboard. The D
tube skins were scarfed over the bend with two 12" sections. Thats
where the project sits..............maybe some day?
