Fig. 1
- The illustration shows the parts required for the wing lin-
kages and servo installation.
Fig. 2
- Locate one of the flap servo wells in the wing centre sec-
tion, and remove the cover over it.
Fig. 3
- Trial-fit the servo mounting blocks, then glue them to the
servo well cover.
Fig. 4
- Drill 1.5 mm pilot-holes for the servo retaining screws.
Repeat this procedure for the second servo well co-
ver.
Fig. 5
- Using a sharp balsa knife, cautiously remove the film in the
centre of the wing through which the servo leads will pass.
Fig. 6
- If you are installing conventional servo wiring, tape the
aileron servo extension lead (1000 mm) to the thread al-
ready fitted through the structure prior to drawing the lead
through the wing.
Fig. 7
- Draw the servo lead through the wing as far as the flap
servo well. Tape the flap servo extension lead (400 mm) to
the aileron extension lead, and draw the leads through to
the centre of the wing using the thread.
Fig. 8
- Route the servo lead out of the centre of the wing.
Fig. 9
- Socket for the aileron servo in the wing centre section.
Fig. 10
- Connect the flap servo to the servo extension lead.

- Connect the servo to the receiver, switch the system on,
and set the servo output arm to centre (neutral). Now re-
move the output arm from the servo, offset it towards the
wing leading edge by one spline, and then fit it on the servo
output shaft again. This increases the down-travel of the
flap.
Fig. 12
- If you are fitting an S-Bus wiring system, simply thread one
servo extension lead (100 mm) into the wing, working from
the outer rib to the centre of the wing.
- Before cutting the servo lead, assign the appropriate chan-
nel number to the servo using the programmer F1696.
Fig. 13
- Cut through the servo extension lead, and cut it to length.
Cut off the socket from the servo lead. The next step invol-
ves soldering the wire ends; protect the covering film with
a piece of scrap card beforehand.
Fig. 14
- Solder the servo lead to the servo extension lead as shown
in the illustration, which uses the white wires as an example.
Before reaching for the soldering iron be sure to fit a
piece of heat-shrink sleeve on each wire!
Fig. 15
- Insulate each soldered joint with a heat-shrink sleeve.
Carefully remove the protective card once the soldering is
complete.
Fig. 16
- Now you can connect the servos to the receiver using a
Hub-2 lead in order to test the servos.
Fig. 17
- Screw the servo to the cover using the retaining screws.
Fig. 18
- You can now screw the servo cover to the wing as shown
in the picture.
Repeat the whole procedure on the opposite side of the
wing.
Fig. 19
- The servo extension lead (400 mm) can now be threaded
into the outboard wing panel. This is accomplished by taping
the extension lead to the thread inside the wing, and dra-
wing it through to the servo well, starting from the root rib.
Fig. 20
- Connect the servo to the radio control system, and set the
servo output arm to the neutral position.
Fig. 21
- Mount the aileron servo on the servo well cover using the
mounting blocks, as described for the flap servo. Connect
the servo to the appropriate extension lead. The servo co-
ver can now be fixed to the wing using the retaining screws
supplied.
Fig. 22
- Join the wing centre section and the outboard wing panel
using the spar, and plug in the servo leads.
Fig. 23
- Before flying the model, the outboard wing panels must
be secured to the centre section with strips of adhesive
tape.
Fig. 24
- Check that the control surfaces are at neutral, then cut the
aileron and flap pushrods to the correct length.
Connect the clevises to the control surface horns and the
servo output arms.
Fig. 25
- Use the spigots to mark the position of the horn on the
control surface.
- Open up the holes in the control surface to accommodate
the horn spigots. Cut down the horn spigots to a length of
about 4 mm.
Fig. 26
- Hold the horn in position on the control surface, and mark
the outline of the horn base. Carefully slit the film along the
outline using a sharp balsa knife, and remove the unwan-
ted film.
