Elevator bar assembly:
Slide the elevator
control beams (C10) onto each end of the
shaft (C9). Place the shaft on top of the lon-
gitudinal seat rails and connect the center
connector to the rear joystick connecting
link (C7D). Finally, add the end fittings (C11)
over the shaft ends and glue to the seat rails.
The elevator cables can be installed at this
time. Leave enough cord for later hookup
.

Aileron control wire lead sheaves:
the forward lead sheaves (C3) – one on each
side of the fuselage) on top of the longitudinal
seat rail at the front vertical rail support. For
the aft lead sheaves, assemble a sheave (C3)
into a body (C4). Install the fittings on top of
the seat rail at the rear vertical rail support
. This figure also shows the quad-
(Figure 4-6)
rant detail and the aileron control lines.
2. Building and Installing the Seat
Supports, Seats, and
Rail Cross Strut
Install the transverse seat supports (two per
seat) on top of the longitudinal seat rails and
also the cross strut between the rails at Sta-
tion 5 that we put off earlier. The seat bottom
is laser-cut. The back is photo-etched alu-
minum. Bend the back to the shape of the
bottom and glue to the bottom. There are
some tabs on the aluminum back to be bent
under the wood seat bottom. Glue the seats to
the transverse seat supports
(Figure 4-7)
On the real aircraft, the seat edges and
Note:
back were usually covered with padded fabric,
and a cushion was used in the bottom. These
are not included in the kit.
3. Rigging More Fuselage
Cross Brace Wires
Now that many parts are installed in the
fuselage, you can rig more of the cross brace
wires using the 0.010" gray nylon cord. But
hold off in way of the engine. The locations
of the turnbuckles and wires are shown on
the plans. Rig the wires just as you did the
drag wires in the wings.
