Wings
(continued)
38.
Turn the panel
right side up
. Wrap the panel over the
top
of the ribs, and “tack glue” the
ribs to the wing panel.
Examine the panel from the
front
and ends. Check for any twist in the assembly. If the
panel is twisted, lightly mist it with glass cleaner and pin it down on a flat surface until dry.
When you are satisfied that the wing panel is straight, “final glue” the ribs to the panel and
spar with CA.
Repeat steps 37 and 38 to build the left wing panel.
39.
Upper Wing:
Begin with the
center
section. Locate the ply spar UW1 (sheet 08/08, 1/32
in. ply) and two each of ribs UW2 and UW3 (sheet 03/08, 1/20 in. balsa). Fit one set of
UW2/UW3 ribs as shown, in one of the notches in the spar. UW2 will be on the inside,
nearest the
center
of the spar UW1, with rib UW3 on the
outside
. “Tack glue” both ribs to
the spar.
40.
Install the second set of ribs UW2/UW3 (sheet 03/08, 1/20 in. balsa) ribs into the other
slots. Orient the ribs so that they face the same direction as the first set of ribs. Rib UW2
will be on the inside, with UW3 on the
outside
. “Tack glue” the ribs to the spar.
41.
Locate the
center
section panel UW4 (sheet 04/08, 1/20 in. balsa). Fit the notches at the
rear
of the panel to the tabs at the
rear
of ribs UW2. “Tack glue” the panel to the
rear
tabs
on the ribs.
42.
Wrap the
center
section panel over the
top
of the ribs. Fit the notches at the
front
of the
panel to the tabs at the
front
of ribs UW2. “Tack glue” the panel to the ribs at the
forward
tabs.
Examine the
center
section from the
front
and ends. Check for twists in the assembly. If
the panel is twisted, lightly mist it with glass cleaner and pin it down to a flat surface until
dry. When satisfied that the
center
section is straight, “final glue” the ribs, panel together
with CA.
43.
Outer Panels:
Repeat steps 37 and 38 to build the
upper
wing
outer
panels from parts
UW5 (sheet 05/08, 1/20 in. balsa and sheet 06/08, 1/20 in. balsa), UW6 (sheet 03/08, 1/20
in. balsa), UW7 (sheet 03/08, 1/20 in. balsa),and UW8 (sheet 04/08, 1/20 in. balsa).
44.
Complete the wing
: Fit the
right
wing panel to the
right
side of the
center
section spar by
sliding the tip of the spar through the slot in rib UW6. Then, fit the notches at the root of the
wing panel to the tabs on rib UW3. Bond the panel to rib UW3 and the spar with thin CA.
Repeat this procedure to fit the l
eft
wing panel to the
left
side of the
center
section.
Set the completed wings aside, until required in final assembly.
