Construction
Wing
The wing is a f lly-sheeted spar-less design that achieves
strength witho t nnecessary weight. The wing is designed
to be permanently attached to the model’s f selage for
str ct ral integrity.
The wing consists of two panels: port and starboard. Each
panel has a top skin and a bottom skin.
Wing Skins
Each lower wing skin consists of two laser-c t and
etched pieces: forward and aft. Gently clean p the
mating edges of the skin pieces with 220 grit paper
on a sanding block.
Lay the two pieces of a wing skin on a flat board or
table, with the o ter s rface p. R n a length of
masking tape along the join line. T rn the assembled
skin over, bend the joint open, and r n a bead of
wood gl e down the joint.
Lay the assembled skin back down on the flat board
– masking tape side down. R n a damp paper towel
over the joint to remove excess gl e. Place a sheet
of wax paper over the assembled skin. Then weight
it down with another board, books or what have yo .
Keep the weight on the skin ntil it is completely dry.
While waiting for the bottom skins to dry, prepare
the top skin material as follows. For each top skin,
join two sheets of 1/16” x 4” balsa sing the tape
and gl e method above.
When the bottom skins are dry, remove the masking
tape from the joints.
Trace the o tlines of the bottom skins onto the top
skin material. Then c t o t the top skins leaving
abo t 1/8” extra material at the trailing edges.
Sand each skin as follows. Lay a skin on a flat board
with the o ter s rface p, and sand it smooth with
120 grit paper on a long sanding block. Be s re to
keep yo r sanding motion at a 45-degree angle to
the joints and wood grain. Clean the skin with a tack
rag.
Note – it sho ld not be necessary to sand the inner
s rfaces of the wing skins. J st be s re to remove
any excess gl e.

Wing Panels
Pin a lower wing skin to yo r b ilding board. (The
lower skins are the ones with the rib and aileron
hinge strip positions etched into them.)
NOTE: Ignore the wing main spar in the constr ction
photos.
Use the laser-c t dihedral ga ge to set the root rib in
position. When satisfied with the fit, gl e it to the
bottom skin.
Gl e the rest of ribs to the bottom skin. Gl e the
aileron hinge strips to the ribs and bottom skin, one
on either side of the laser-c t separation line. DON’T
gl e the aileron hinge strips together.
NOTE: Use scrap 3/32” material to pack the leading
edge of the bottom skin p so that it is in contact
with the f ll length of each rib.
Fabricate aileron torq e rods from 3/32" al min m
t bing and 1/16" m sic wire.
Gl e torq e rod t bing to the bottom skin BUT NOT
to the aileron. Gl e blocks on either side of the
aileron crank. Do not c t the aileron o t at this time.

Gl e the 1/16” s b-leading edge to the front of the
ribs.
Sand the wing panel str ct re so that the aileron
hinge strips and crank blocks match the wing rib
conto r. Sand the top of the trailing edge so that it
tapers to abo t 1/32” width. This provides a gl ing
s rface at the trailing edge for the top skin.
Pin a wing panel to the b ilding board, sing the
laser-c t washo t jigs to establish 1/8” wingtip
washo t.
Gl e the 1/16" top skin to the wing panel str ct re.
Let the gl e c re thoro ghly before npinning the
wing panel from the b ilding board.
NO E – The laser-c t 1/8” leading edge strip is not
wide eno gh to cover the entire leading edge. To
remedy this, simply c t a 1/8” inch wide strip from
the excess 1/8” sheet and edge-gl e it to the laser-
c t leading edge.
Gl e the 1/8” laser-c t leading edge to the wing
panel.
Gl e the laser-c t wingtip to the tip rib. NO E –
laminate a scrap of 1/16” sheet to the top of the
wingtip block.
Shape the leading edge and wingtip of each wing
panel to the shapes shown on the plans.
Prepare to join the wing panels by pinning one wing
panel, with its washo t jigs, to yo r b ilding board.
Jig the other wing panel so that its center rib
matches the center rib on the pinned-down panel,
and raise its wingtip 2” above the b ilding board.

Gl e the panels together. We s ggest 15-min te
epoxy for this joint.
Wrap the center section of the assembled wing with
a strip of 2.6oz fiberglass cloth. Soak the cloth with
thin CA gl e.
C t the ailerons free from the completed wing.
Bevel the aileron leading edges slightly to allow for
3/16” movement both p and down.
Hinge the ailerons to the wing.

Install the aileron servo and linkage in the wing.
Fuselage
First, determine how many spacer rings yo ’ll need
for yo r motor, prop adapter and spinner
combination. Attach yo r motor to the plywood
firewall F1. Then set p the prop adapter and spinner
as they’ll be on the finished model. Adj st the
n mber of spacer rings ntil yo get a nice fit
between the spinner and the spacer – abo t 1/16” is
fine.
Gl e the 1/16” balsa do blers to the f selage sides.
Be s re to make a left and right side!
Gl e a 1/8" sq. balsa strip along the lower edge of
the f selage side from F4 to F7.

Gl e F2, F3 and F4 to one f selage side making s re
they are aligned 90 degrees. Then gl e to the other
side.
NO E: Dab a weak sol tion of ho sehold ammonia on the
f selage sides to make them bend easily.
P ll the tail together and place formers F5, F6 and F7
in place. Sec re the lower part of the formers to the
f se sides with thin CA.
Gl e the plywood firewall F1 in place.
Gl e a 1/8" sq are balsa stringer to the top of the
rear formers.
Moisten the top half of the f selage sides and gently
press them against the top portion of formers F4, F5,
F6, and F7. Sec re with thin CA.

Add the 1/8" balsa stringer to the lower rear
f selage.
Add 1/4" balsa blocking to the forward f selage to
allow for sanding to a ro nded shape.
Gl e 1/4” balsa triangle strips to the top of the
f selage sides aft of the firewall F1 to provide more
material for shaping the nose.
Gl e the two 1/4” balsa bottom blocks together, then
gl e them to the bottom of the forward f selage.
Gl e the appropriate n mber and size spacer rings to
the forward f selage. Use yo r motor and spinner
combination to select the correct spacer rings.

Gl e the two 1/4” balsa top blocks together, then
gl e them to the top of the forward f selage.
Install a temporary spinner to aid in final sanding of
the forward f selage. Sand the nose to shape.
Sheet the bottom of the f selage with 1/16" balsa.
