Install Wing Top Sheeting - GREAT PLANES F-15 EAGLE Instruction Book

D 21. Sand the area near where the main spars
join to remove any high spots. Securely glue a
die-cut 1/32" ply spar joiner (F154F18) in place as
shown in the photo.

INSTALL WING TOP SHEETING

D 1. Lightly sand the tops of the ribs to blend
with the notched trailing edge. Cut two 1/16" x 7/8"
x 18" balsa trailing edge sheets (F154W15) to fit
from the wing centerline to the outside edge of the
#8 ribs. Use weights to make sure the rib jig-tabs
are all against the work surface and glue the TE
sheeting in place. NOTE: The edge of the TE
sheet may not be exactly straight, but just position
the sheet so it slightly overlaps past the TE. Any
overlap can be sanded off flush with the TE later.

D 2. Make four leading edge sheets by cutting a
triangle 2-1/4" wide and 13" long off of one end of
2-1/4"

each 1/16" x 3" x 30" balsa wing sheet
(F154W14). HINT: Use a hobby knife and cut a
straight line using a metal straight edge. Flip the
triangle over and glue it to the rest of the sheet as
shown in the sketches above.
D 3. Sand both sides of each LE sheet smooth
with a sanding block and fine grit sandpaper.
D 4. Before applying the leading edge sheeting
in the next steps, use your T-bar to lightly sand off
the edges of the shear webs and smoothly blend
the ribs to the main (front) spar. Also, clean up the
LE\rib joints to remove any excess glue.
D 5. Sand the front edge of the LE sheeting
(the edge that includes the triangle) to a slight
bevel so it will fit snugly against the back of the
leading edge. Trial fit it in place before
proceeding. Position the sheeting left or right until
the aft edge of the sheeting is approximately in the
middle of the spar. Note: The sheeting must
extend past the wing tip. (see photos on page
34).
NOTE: It will be helpful to have the
following items handy for the next
steps: thin CA, thick (slow cure) CA, a
straight piece of wood (such as an
aileron) and a wet cloth.
