pipes, foundation shoes and holes in the ground). Make a mirror template on the newly
constructed one and attach this to the side so that the wing is constructed in one piece.
It is recommended that the wing template be made stronger than suggested in the
basic instructions. More rib outline sections are desirable (as shown in the photos above).
Wing coatings have a tendency to twist during cure to a tighter radius than the initial
airfoil contour, so significant weight is required to fit the rib contour. Keep this in mind
when making the template for assembling these items. Elongated sandbags (such as those
made from old trouser legs) are ideal for securing the coating to all surfaces, a total of
500 kg for gluing the bottom coating to each wing.

Preparation of the top wing coating
Select the proper wing coating for each side of the wing you are planning to
assemble (the inner section of the wing's top coating can be identified by the extra layer
of glass in the area intended for stepping on top). Remove all peel ply and any residual
molding material, especially in the areas where the spar and ribs will be glued. Finishing
on the edges. The inner edge of the coating will be on the BL 23 ¾. Position the upper
wing coating on the frame by pulling the front outline into place in the mold. Secure in
place with a few superb screws threads.
