I was thinkin of keepin those five plywood pieces for the fixed undercarraige in the wings but modifying the ends to accomodate retracts. That way the dihedral stays the same.
I was just thinkin since the wings are 2 seperate pieces it would be a pain in the ring to rig the air tubes/retract pushrods into the fuselage. i might not bother with retracts, they would be cool but its too much money for me

"inner-leading edge of the wing"
are you talking about the part you have to build into the fuselage, where the wing and fuselage blend into each other?

I havnt come that far yet, im probably gonna fit the wings to the fuselage while i build them. im thinking of building them onto the fuselage because it will be easier to glue a balsa to balsa joint,

Sorry if im making no sense, im not in a problem solving state right now
