From KAVAN RC Wiki

Glue the wing main spar 7 (3×8 mm spruce stick) into the notches in the upper side of ribs (trim the bottom edges slightly to slip easier in). Glue only the bottom of the main spar to ribs 5. Insert partly the wing joiners 42 along the sides of the main spar in order to get the correct alignment in the wide notches (DO NOT glue the joiners yet!). Fit and glue the upper central sheeting 8 and 9 (Det. B–B) in place. Apply some additional glue to all joints if necessary and let cure.
