to the fuselage) and run cyano along the joint between the
fuselage and the wing; avoid excess glue running out of
the joints. Check the alignment of the wing once again, as
shown in Figs. 29 and 30 (note the reference points).
17. Installing the servos, connecting the control sur-
faces
Place the aileron servos in their recesses, and secure them
with a drop of glue applied to each mounting lug. Connect
the pre-formed end of the pushrods 29 to the servo output
arms. Slip the pushrods through the swivel pushrod con-
nectors on the aileron horns, set the servos and ailerons
to centre, then tighten the clamping screws 27 in the con-
nectors 24. Fig. 31
18. Installing the tailplane and rudder
Trial-t the tailplane 8 in its slot, and check that it is at right-
angles to the fuselage. Carry out any trimming required,
then glue it in place permanently.

Attach the rudder 10 to the n using the hinges 22.

19. Connecting the servos to the elevator and rudder
Connect the pre-formed end of the rudder pushrod to
the outermost hole in the servo output arm. The swivel
connector should be mounted in the third hole from the
outside of the horn in the rudder 10. Tighten the nut of the
pushrod connector just to the point where the barrel swivels
smoothly, but without slop. Apply a tiny drop of thread-lock
uid or cyano to the outside of the nut to secure it. Repeat
the procedure with the elevator pushrod 30.

20. Installing the motor
Screw the motor to the rewall 32 together with the four
socket-head adjuster screws 33 and the two screws 34
which hold the rewall in place.

Connect the speed controller. Switch on the radio control
system and check the direction of rotation of the motor shaft
(without a propeller): when you view the motor from the
front, the output shaft must rotate anti-clockwise. If that is
not the case, swap over any two of the three motor wires.
Caution: do not connect the ight battery to the speed
controller unless you have rst switched on your transmitter,
and you are certain that the throttle control is at the “OFF”
position.
Fix the speed controller in the fuselage using hook-and-loop
tape; the best position is in the vacant area on the right-hand
side of the fuselage. Secure the cables by gluing them to
the fuselage side with hot-melt adhesive.
The “ParkMaster 3D” brushless power set # 33 2652 forms
the ideal power system for this model.
The items included in the power set are perfectly matched
to each other, and the system has been thoroughly tested. If
you prefer to use a different battery, speed controller, motor
or radio control system components, this is left to your own
discretion, but we are unable to provide support in this case.
21. Gilding the lily - applying the decals
The kit is supplied with two decal sheets 2; the individual
name placards and emblems are already plotted. Apply
them to the model in the position shown in the kit box
illustration, or in an arrangement which you nd pleasing.
22. Balancing the propeller
It is essential to balance the propeller of any model aircraft,
otherwise it will not run smoothly and without vibration.
The propellers we supply are manufactured to very tight
tolerances, but may still be very slightly out of balance. We
recommend our propeller balancer # 33 2355 for this task.
23. Fitting the propeller
There are a few points to note when tting the propeller,
the taper collet and the spinner nut.
Tightening the rewall screws:
Before running the motor for the rst time it is important to
check that all screwed joints are tight; re-tighten them if ne-
cessary. The sidethrust and downthrust adjustment screws
must be tightened to the point where the screw ends rest
squarely on the plastic support.
Caution when attaching the propeller hub:
Check that the diameter of the centre bore of your propeller
is correct for the propeller driver. The propeller must rest
rmly and squarely against the driver.
Checking the propeller for true running:
Before ying your model for the rst time it is sensible to
check that the motor and propeller run smoothly and true:
secure the model, and check that the propeller is rmly
xed, is free to rotate, cannot injure spectators, and is not
in a position to suck loose objects into the airow. Slowly
open the throttle, and observe the propeller. If you detect
any hint of resonance as you increase speed, interrupt
the procedure immediately, and check all the points listed
above. Don’t be tempted to y your model until the motor
and propeller spin smoothly and without vibration.
24. Initial test-run
Install all the receiving system components as shown in
Fig. 37, and connect them as described in the RC system
instructions; use the hook-and-loop tape 20 + 21 to secure
the components. Check the neutral position and freedom
of movement of the control surfaces, and the direction of
rotation of the servos. Check the direction of motor rotation,
and reverse it if necessary by swapping over any two of the
three connectors.
25. Centre of Gravity
The CG should be corrected as far as possible at the stage
of installing the ight battery.
The model should balance at a point in the range 110 - 120
mm aft of the wing root leading edge, measured on both
sides of the fuselage.
Once you have found the correct battery position, use a
sharp balsa knife to cut out the area of foam above the
