4. Accurately measure and mark the middle of the
leading edge and the TE spar on the bottom of the
center section of the wing. Lightly draw a centerline
across the bottom of the wing using a straightedge to
connect the two marks.
❏
5. Using the centerline on the bottom of the wing
as a reference, center the wing in the fuse. Trim the
fuse sheeting where necessary until the LE of the
wing contacts the aft edge of former F3B and the
rest of the wing fits well. (This is most easily done
with the wing and the fuse upside-down, but is
photographed upright for illustration.)
❏
6. Use the template on the plan to make both air
passage fairings from the 1/4" x 1-1/2" x 9" balsa
sheet. Glue the fairings to both sides of the fuse
where shown. Sand the air passage fairings to match
the fuse.
❏
7. Note the embossed lines across both die-cut
1/32" [.8mm] plywood aft wing fillet bases (FB).
Carefully, without breaking them, bend both aft wing
fillet bases upward at the lines. Tape the aft wing fillet
bases into position on the fuselage.
❏
8. Tape both die-cut 1/32" [.8mm] plywood
forward wing fillet bases to the fuse the same way.
❏
9. Using the 1/4" [6.4mm] holes in formers F3B as
a guide, drill 1/4" [6.4mm] holes through both F3Ds.
For those who wish to do so, now is a good
opportunity to check the wing incidence. The
correct wing (and stab) incidence is built into this
model and is preset by the die-cut ply fuse sides
and lower stab saddles. Checking the incidences is
not necessary, but some modelers prefer to do so
anyway. A wing incidence meter (such as the Great
Planes
® Accupoint ™ Laser Incidence meter,
GPMR4020) is required to check the incidence.
