22 To glue on the bottom leading edge sheeting use the following sequence. Apply aliphatic resin glue to
all ribs between FLE and SW. Then apply medium or slow CA to the spar. Install the leading edge sheet
and hold it firmly against the spar until cured. Next using finger pressure, pull the leading edge sheeting
firmly against each rib to make good contact with FLE. Use thin CA to glue it to FLE. Proceed from the
center out toward to both end of the wing

Install the 1/4” balsa leading edge and then add LEF at the root end.
£
24
Laminate two 1/4” WT parts together to form the wing tip block and then glue in place.
£
25 Assemble the remaining wing half by repeating steps 1 through 23.
£
26 To assemble the wing halves cut two 1/2” pieces of 1/8” dowel and glue them into the holes in WJ.
These will serve to align the two wing panels. Glue WJ to one wing panel and then glue this assembly
to the remaining wing panel. Use Epoxy to glue SFJ to the spar flanges on the top and bottom of the
wing. Note that WJ is cut 1/64” oversized to accommodate sanding out flush with the wing sheeting.
FINISHING THE WING
It is best to finish shaping the leading and trailing edges after the wing halves have been assembled. Do
not shape the wing tip trailing edges until you have completed the aileron assembly. Use LEF as a guide
to shaping the leading edge, also use the supplied leading edge template to check for the correct shape.
This work is best accomplished with a razor plane and a sanding bar. The tip block leading edge (WT)
can be formed at the same time as the leading edges. To finish forming the tip block, first assemble the
ailerons. Tape them in place along the entire aileron leading edge and then align them with the wing
trailing edge at the root and tape them in place. Use the aileron tip to mark the wing tip block (WT) and
do the final shaping of the wing tip block. Note that 3° of wash out is introduced into the outer wing panel
from W8 to the tip. Sand the trailing edge to a rounded contour.
AILERON ASSEMBLY
£
1 Locate and prepare the aileron base (AB). Install Al, note the Al must be canted in slightly, use the
aileron dihedral gauge (ADG) to set the correct angle.
£
2
Install and glue A2 through A5. Note that these must be at 90° to AB. A5 simulated the aileron counter
balance and must be parallel with the end of the aileron base.
£
3 Plane a slight bevel on the bottom of ALE to provide good contact with the aileron base, and then glue
it to the aileron base and the front of Al through A4.
£
4 Glue the aileron horn plate (AHP) to the aileron base where indicated.
£
5 Plane the top leading edge of ALE to contour with the ribs. The aileron will be attached to the wing
with aileron tape along the top leading edge after covering.
STABILIZER ASSEMBLY
Building note:
When installing the stabilizer parts onto the core sheet, make sure the parts are pressed flat against the
bench. This is especially important for the leading and trailing edge installation. Remember that the
shape that the stabilizer is in when you apply glue is the shape it will retain.
£
1
Install all split ribs on one side of the stabilizer core sheet. Start with S-1 and proceed out in both di
-
rections to the tip.
£
2 Install ETE trailing edge.
£
3 Install SD ply brace.
