c 16 16. Install and glue a 1/8” sq. balsa in the
notches provided in the leading edge of each
rib. This will serve to stiffen the top sheeting.

Glue a piece of 1/8” square scrap to each side
of the servo mount to help secure it to W7 and
W8. See photo E.
Trim the bottom spar ush with W10 at the
tip.
c 19 Install and glue the 1/8” x ¼” top spar. Trim
the top spar ush with W1 and W10
c 20 Glue sheer webs in each bay between the ribs
as indicated on the plans.
c 21 Install and glue the geodetic ribs G1 through G6 in each bay. Note that G1 has some material removed to
accommodate the sheeting. Sand a slight bevel on each end of these ribs to increase glue land and improve
the t. These ribs may have to be bowed slightly to install but should be straight after they are installed.
c 22 Install and glue the wing tip (WT) to rib W10. Use the gusset (WTGU) at the location of the spar to set the
correct angle. Glue a ½” piece of ½” triangle stock ller at the trailing edge and a ¾” piece of ½” triangle
stock at the leading edge.
c 24 Trim the bottom center section sheeting (A) to butt t to the leading edge and then glue it to W1, W2, W3
and the leading edge.
c 25 Shape the leading edge to contour with the ribs in preparation for installing the top leading edge sheeting.
Trim and sand W10 and the wing tip to match. Note that W10 is offset 1/32” aft of the spar to accommodate
the 1/32” tip sheeting. W1, W2 and W3 are also offset in this same manner so that after sheeting they will
be ush with the rest of the ribs.
c 26 Glue the top aft center section sheeting (D) on. Note that this sheeting should slightly overlap the top
spar.
Run a bead of thick CA down the top spar and
install the top leading edge sheeting. Glue it
only to the top spar at this time. Use a straight
edge to press the sheeting into contact with
the top spar.
c 28
c 29 Turn the assembly over. Apply enough me-
dium CA to the front of W2 until it runs down
the top of the rib as far back as the spar and
then hold the top sheeting into contact with
W2 until it cures. Apply thin CA to the lead-
ing edge and the top sheeting. Moving down
the wing from the root, glue the top sheeting
to each rib and the leading edge.
c30 Remove the dash cut material in W1 between the top and bottom spars.
This completes assembly of one wing panel, repeat steps 1 through 30 for the remaining wing panel.

c 23 Remove the wing assembly from the plans.
c 27 Plane or sand TE-B to contour with the trailing edge (TE-A) and the center sheeting.
