ribs - to the bottom spar and ribs with medium CA.
Set the outermost shear web for the last set of #2 ribs
aside for now. Remove the crossed T-pins that are in
the way, but reinstall them through the shear web after
you glue it in place.
Q 26. Cut and glue five shear webs in the right side
of the center wing panel the same way.
Q 27. Position the 1/16" x 1-3/8" x 30" balsa
upper TE sheet on the ribs. Mark the location of the
1/8" x 3/16" basswood stick and cut a notch in the
TE sheet. Glue the TE sheet in position with medium
or thick CA.
LJ 31. Sand the ends of the spars and TE's and LE
so they are flush with the end ribs.

Q 28. Test fit the 1 /8" x 3/8" x 3" basswood top
spar in the notches of the ribs. If necessary, adjust
the notches and the tops of the shear webs so the
spar is fully seated into the ribs. Glue the spar in
place with medium or thick CA.
Q 29. Use the remainder of the 1/16" x 3" balsa
sheet to cover the top center section of the wing
between the top spar and the top TE.
Q 30. Remove the T-pins. Lift the panel from your
building board and peel the wax paper off the wing.
The 1/16" shims you placed under the front of the
#1 ribs should fall off.
Q 1. From the 1/16" x 3-7/8" x 5-7/8" plywood
sheet, cut and glue a 1 /2" wide strip to fit between
the #1 ribs against the LE. The grain should run
lengthwise.
Q 2. Cut a 1/4" x 1/4" hatch tongue from the
same 1/16" plywood sheet. Glue it to the top of the
bottom spar as shown in the Bottom View Of Servo
Tray sketch on the plan.
Q 3. Cut the hatch from the 1/16" plywood sheet.
There should be approximately a 1/8" gap between
the sides of the hatch and the #1 ribs. You can see
the hatch in the following photo.
