The wing is made up of an inner and outer section for the simple reason that the thickness changes at that joint.
parts:
However, I am building the model with the gear down and therefore need to cut out the landing gear doors from the bottom of the wing. Since the door is at the mating splice, I have to join the wings first before cutting the doors out.
to do that, I temporarily inserted and lightly glued the middle rib to provide a support when the wing skins are joined and you can press it down for the glue to properly adhere.
here is the wing
note:
now remove the middle rib. It will be cut up to suit later on.
