Glue the wing panels together using epoxy, taking care to line up the top and bottom
surfaces accurately.
Glue the wing joint braces together using wood glue. Allow the joints to set hard, then
glue them in the wing together with the ply reinforcements and the wing screw plate.
Assemble the main undercarriage units as shown in the photos; apply a drop of UHU
thread-lock fluid to all the screws to prevent them working loose.
Attach the air lines to the retract cylinder. Place the retract units in the mountings, drill
pilot-holes through the support lugs, and fit the retaining screws to secure the units. Glue
the compressed air lines in the channel using UHU por. Run the ends of the compressed
air lines to a Y-connector or T-piece.
Cut a slot at the appropriate point in each aileron to accept the horns, and push the
horns into the slots. Fit the spreader plates on the horn spigots from the other side, cut
off the excess spigot material and glue the plastic parts together (plastic-to-plastic only).
Caution: don't allow glue to contact the styrofoam.
Screw the swivel pushrod connectors to the aileron servo output arms and check that
they rotate smoothly. Connect the pre-formed pushrod ends to the aileron horns, then
run the plain pushrod ends through the swivel connectors. Set the servos and ailerons to
centre (neutral), apply a drop of UHU thread-lock fluid to the grubscrews and tighten
them fully. Snip off the excess pushrod material.
Roughen the elevator servo cases using glasspaper, and set them to neutral from the
transmitter. Screw a large servo output arm on each output shaft, connect 750 mm
extension leads to the servos, and secure the connections as described earlier. The
elevator servos can now be epoxied in the appropriate recess in each fuselage shell.
Mark the position of the servo leads on the inside of the fuselage, and melt channels for
them using the soldering iron, as described earlier.
Assemble the ducted fan unit and motor as shown in the photograph and drawing.
Position the tail pipe in one fuselage shell; it should butt up against the end-stop at the
impeller end. Note that the small opening (efflux) must be at the tail end, and the large
opening (intake) at the impeller end. When you are satisfied, glue the pipe in place using
UHU por.
Glue together the hardwood mounting plates for the ducted fan unit, and allow the joints
to harden fully. Epoxy the mounting blocks in the fuselage shells at the points indicated.
The rear fuselage shells can now be glued to the front fuselage shells using UHU por.
