CONSTRUCTION SOPWITH CAMEL
them together. Add the aileron ribs, then
fit the wing-tip parts into place. Glue the
top TE strip onto the TE sheeting, trim the
TE assembly to fit the wing tip, then glue
everything together. Cut the ailerons free
just before covering the wings.
Build the top wing halves over the plans,
then join them together. Laminate the
center cutout bow from balsa strips, and
glue it into place. Use a razor saw to cut a
1/8-inch-wide section out of the ribs just
in front of and behind the main spars, and
epoxy the plywood center braces into place
with 30-minute Z-Poxy. Clamp the panels
and braces together until the epoxy cures.
Add the vertical-grain balsa sheer webbing
to the front and rear of the main spars, then
frame out the center window with lite-ply.
Sopwith Camel | X1215A
Designed by Gerry Yarrish, this 1/4-scale WW I biplane has the looks of the classic
British dogfighter and the heart of a sport flyer. It is CAD-designed, and laser-cut
parts are available. Easy to build, the Camel has a one-piece top wing and plug-in
lower wing panels. Complete building details are available at ModelAirplane

A wing-alignment jig is shown on the
plans. Glue it together, and tack-glue it to
the fuselage where the hatch cover fits.
Once the plywood attachment plates and
blind nuts have been installed in the top
wing, center the wing and tack-glue it
to the jig.
Bend the cabane wires to shape, and
slip the bottoms into the four fuselage
holes. Attach the solder lugs to the wing
with 6-32 cap-head screws, and bend
the barrel sections down. Cut the wires to
length, and slip them into the lug fittings.
Fit all four cabane wires into place, then
use scrap lite-ply and Z-Poxy to capture
the bottom ends against the inside of
the fuselage sides. Measure the distance
from each wing tip to the tail post, adjust
until the distances are equal, then solder
the cabane wires into the fittings. Let
everything cool o;, then add the 1/16-inch
X-brace wires and solder them. Remove
the wing, discard the jig, and clean all
Shown here is the completed stab and elevator assembly. Firewall, front formers, and the wing-saddle doubler are glued into place before
joining the fuselage sides together.
