1. Locate three plywood wing joiners. Glue them together
with epoxy, forming one plywood wing joiner. Set them aside
until the glue hardens.
❏
2. Locate the 3/16" x 3/4" [4.8 x 19mm] dowel. Glue it into
the hole at the rear of the root rib of one wing, positioning
one half of the dowel into the hole.
❏
3. Apply 30-minute epoxy to all sides of the wing joiner,
the joiner pocket in both wing panels and the root rib of each
wing panel. Insert the wing joiner, push the wing panels
together and hold them in place with masking tape. Before
the glue hardens, set the wing flat on your bench and
measure the dihedral. The distance from the top of the
bench to the center of the wing as measured at the wing tip
should be approximately 3-3/8" [86mm]. Block the wing tip
up while the glue hardens.
Note: Due to production
techniques there may be some variance in the actual
dihedral of each model. Our prototypes flew well with the
dihedral anywhere between 3" and 4" [76mm and 102mm].
❏
4. Place the plywood wing bolt mounting plate in
position on the bottom of the wing, over the wing bolt holes.
Using a fine-tip marker, trace the outline of the plate onto the
wing. Use a sharp #11 hobby knife or use the Expert Tip
that follows to cut the covering from the wing along the lines
you have marked. Use care to cut only into the covering
and not into the wood.
