Not sure yet if I am going to mount the power pod to the center section of the wing than glue the center section to the fuselage or use blind nuts and bolt the center section to the fuselage.
The first wing rib in the photo is 1/8" hard ply which the power pod will glue to,,, the second wing is double 1/4" balsa the spars will be cut between the two 1/4" balsa to make for a 3 section wing.
Once the epoxy sets on the 1/8" ply rib the area between the top and bottom spar will be taken out for the wing joiner to fit through.
