Layout the bottom beds on a flat surface. Tape them together. Repeat for top beds. Align
the cores together on the bottom bed. Spray the root end of the wing cores with #77 spray
adhesive. Put a piece of clear wrap or wax paper between the beds and the cores to pre-
vent sticking. Let the adhesive dry for 10 minutes. Put the wing cores together using beds
as a jig.
(See Figure 2) Measure 11 3/4” from the nose along the center line and make a mark. Use
a square to measure 2 1/2’’ on both sides of the center line. Mark the 5” line and make
two lines parallel to the center line from the ends of the line to the trailing edge (TE). Cut
along the lines and remove the foam.

( See Figure 3) Install the carbon spar on the bottom of the wing. Measure 8” back
from the nose and make a mark. Draw a line perpendicular to the center line from leading
edge to leading edge. Router or cut a groove deep enough to bury the carbon spar. The
spar may be installed with 3M Super #77 Spray Adhesive (#77) to save weight. Spray a
puddle of #77 into a small cup. Spread the glue in the spar groove with a small brush or
swab. Spray the carbon spar with the #77. Let the glue dry for 15 minutes. Push the spar
into the slot. Let the glued spar set over night before taping over with fiber tape. Epoxy
may be used instead of the #77 to save time. Let the epoxy cure and apply a layer of fiber
tape over the spar.
