From KAVAN RC Wiki

Glue the wing main spar 5 (3–8 mm spruce stick) into the notches in the upper side of ribs 1. Do not glue it to the root rib 4 yet. Glue the gussets 6 in place. Apply some additional glue to all joints if necessary and let cure. Now you can assemble the other half of the wing in the same way. Just remember you are building left and right halves, not two lefts or rights.
