Wing panels

Note: The outer wing panels are to be built in the same manner as the wing centre section; just the top spar is to be glued later, once the washout has been set (see later). You can build both panels at once.

Pin down the bottom main spar 16 (6×2mm spruce stick) laid over the supporting 5×1.5mm balsa stick 1 on the building plan protected by a clear plastic film - refer to Det. A. Glue all the ribs 3 to the bottom spar as well as the root ribs 18L and 18R - the bevelled side outwards (refer to Det. H-H).
Glue together the 6×2mm spruce stick 19 and 6×4mm balsa stick 20 to form the leading edge as you did before.
Glue the leading edge to the front of 3 and 18L/18R ribs.
Remove the wing panel frames from the building plan, put glue into the notches in the left trailing edge 21L/21R and attach it to the ribs so the bottom of the trailing edge matches the bottom edge of the ribs. Before the glue sets; check the correct position of the trailing edge using the supplied jig 14 (Det. B).
Before the glue has cured, lay down the wing panels over the building plan, support the root ribs 18L/18R with the balsa stick 1 near the trailing edge - so you can pin the frame down without any change to the wing profile. Pin the wing panels down at the ends of the leading edges and at the root of the trailing edge. Support the tip end of the trailing edge (where the wing tip 23 will be attached later) with a 5mm scrap of balsa or spruce stick to form the washout - it improves the stability of the model significantly. The washout of both two wing panels has to be the same.
Glue the 6×2mm spruce top spar 22 into the notches in the ribs 3.
Cut the triangular gussets 13 from 1.5x8mm balsa stick and glue them into the corners.
Cut and sand the overlapping spars, leading and trailing edges 19+20, 16, 22, 21 flush to the bevelled root ribs 18L/18R.
Glue the wing tips 23 in place and round their outer edges (Det. H-H).
Sand the leading edge of the wing centre section and wing panels to shape (Det. G).
