10. Arranging the cables, installing the RC
components
Lay the cables in the cable ducts, and apply adhesive
tape over the top to seal the ducts. Stick the Velcro
(hook) tape where the RC components will be located.
Note that the adhesive power of the Velcro tape is not
sufficient, so it should be glued in place with cyano.

11. Completing the canard
The next step is to glue the sleeve 33 in the canard 6.
Push the sleeve in until the flange lies flush with the top
surface. Apply glue to the outside of the sleeve from the
underside. Check that the fins 7 + 8 fit “dry” (no glue),
then glue them in place permanently. Figs. 14 + 15
12. Completing the engine nacelles, fitting the
propellers
Place the engine nacelles 9 + 10 and fins 7 + 8 on the
model and fix them in place with the O-rings 36 - they
cannot be fitted later as they will not fit over the
propellers. Separate the propellers from the spinners
(black), turn the propellers round (the raised inscription
should now face back), and fit the spinners again. Push
a modelling pin through the spinner from the rear
towards the front to make a hole. The hole allows trapped
air to escape when the spinners are glued in place. Fix
the propellers to the motor shafts using 5-minute epoxy
or UHU Endfest 300 (slow-setting epoxy). Fig. 16
Don’t use cyano!!! This makes the material brittle,
and the spinner will fall off.
13. Attaching the latch lugs to the fuselage top
decking
The latch lugs 23 are fitted in pairs, starting with the
two front ones. Apply “ZACKi medium” to the patterned
surface > no Activator! <, then push the latch lugs half-
way into their slots. Place the fuselage top decking 15
on the model, allow the latches to engage, then
immediately move the decking to exactly the right
position. Wait for about one minute, then carefully raise
the decking again and lift it off. Spray Activator on the
latch lugs. Install the centre and rear pairs of latch lugs
in the same manner. Fig. 17 + 18
14. Final assembly
The recommended position of the radio control units
and power system components is as follows:
Receiver furthest forward, followed by the flight battery
and speed controller.
The final position of the flight battery is determined when
you check the model’s balance. Ensure that the Velcro
tape which retains the battery is securely fixed and
properly engaged. If you neglect this point you may lose
the battery while the model is in flight.
Check that the battery is secure
before every flight!
Pierce a hole through the fuselage side and into the
wing duct; lay the receiver aerial in the duct and secure
it with adhesive tape.
The next step is to connect all the working systems in
the model temporarily.
Don’t connect the motors until you have
switched on the transmitter and checked
carefully that the throttle stick is at the “OFF”
position.
Connect the servo plugs to the receiver. Switch on the
transmitter, then connect the flight battery (in the model)
to the speed controller, and the controller to the receiver.
This model requires a speed controller with an integral
BEC circuit (receiver power supply from the flight
battery).
Now switch on the motors briefly and check that the
propellers rotate in the correct direction. Remove all
light, loose objects in the area behind the model before
you do this, and hold the model firmly.
Caution: even small motors and propellers can
cause injury!
15. Control surface travels
It is important to set the control surface travels correctly,
as these settings have a crucial influence on the model’s
overall control response. Caution: the elevators (the
canard panels) should move down through approx. 22
mm when you apply up-elevator (stick back), and around
24 mm up when you apply down-elevator (stick forward).
The aileron travels should be 12 mm up and 9 mm down,
in all cases measured at the point of maximum aileron
chord.
If your transmitter does not feature servo travel
adjustment you may need to make mechanical
adjustments to the linkage.
16. Balancing
If your Sonic Liner is to fly safely and stably it must
balance at the correct point - just like every other aircraft.
Assemble your model completely, ready to fly, and install
the flight battery. You will find markings moulded into
the underside of the wing, close to the hand-grip areas.
Support the model on your fingertips at these points,
and it should balance level. If necessary, adjust the
position of the flight battery until this is the case. Once
the correct position is found, mark it inside the battery
box to ensure that the battery is always replaced in
exactly the same location. Fig. 20
