Steering and rear
suspension tie rods
The two longer rods, the steering tie rods, make up part of the steering
system, and they will later be connected to the steering servo saver. The
shorter rod is one of two tie rods that, with a ball end screwed onto each end,
you will fit to the rear suspension. The ends of all these rods are counter-
threaded to prevent the ball ends coming loose, and to make it possible to
adjust their overall length without dismantling them.
1 As well as the parts
supplied with this stage
(excluding the ball-
headed screws), you will
need a pair of pliers and
some tissue paper, and a
caliper gauge, preferably
digital (see Step 4).
2 Because the steering
tie rod ends are counter-
threaded, to fit a ball
end on one end, you
have to screw it on
clockwise, and to fit one
to the other end, you
must instead turn it
anticlockwise.

3 Wrap some tissue paper
around the middle of one of the
steering tie rods. Hold the rod
with pliers, as shown, and screw a
ball end onto each end. Then
repeat the process for the second
steering tie rod.
4 Both steering tie rods must be
the same length – about 66mm –
when assembled. Measure the
length using a caliper gauge.
5 Now you will need the two
remaining ball ends and the rear
suspension tie rod.
6 Screw the two ball ends onto
the rod.
7 Adjust the distance between
the ball ends to about 2.5mm.
8 Store the three assembled
tie rods, along with the unused
ball-headed screws, until they
are needed.

Servo and servo horn
The parts supplied with this stage are one of your model’s two servos, and a servo
horn. Both servos are the same. When fixed to the chassis plate, one will operate
both the throttle and the brake, and the other one the steering.
You cannot yet fit the servo, so these two pages will provide you with some details
about servos and how they work. This information will be useful if you have any
problems with a servo when it’s in use.
Parts supplied:
A Servo
B Servo horn

Technical data
The Huracán’s servos are 38.6mm long, 18.8mm
wide and 34.9mm high. Each one weighs 37g,
and its operating voltage range is from 4.5 to 6V.
Their output power is about 4.5 to 5 watts,
while the operating speed is 0.17s/60° or
0.14s/60°, depending on whether the batteries
are 4.8 or 6 V.
This picture shows the
throttle/brake servo,
mounted on the right-hand
side of the chassis. It is
complete with its servo
horn and the throttle and
brake linkages that the
horn operates.

The internal structure of the servo
On the bottom of the servo casing, you can see
the heads of the four long screws holding the
base in place. If you remove these screws, you
can separate the three sections of the casing.
With the base of the casing removed, you
can see the circuit board that translates the
signals coming from the RC receiver into
commands that operate the mechanism of the
servo. Removing the top of the case will
Right: The three sections
that make up the casing of a
servo are held together by
four Phillips screws. By
removing the screws, you
can take off the casing’s base
to reveal the circuit board.
Above: The bottom of a
servo, with the casing
removed. The circuit board
houses an electric motor
(arrowed), which drives
the servo mechanism.
Below: The inside of the
top of the servo casing.
Left: Removing the top of

expose the gears, which transmit the motion
of the motor to the servo horn. The gears also
slow down the motion, thereby increasing the
torque it applies to the servo horn so that the
linkages can exert the force required to move
the steering, throttle and brake mechanisms.
The gears, which are toothed plastic wheels,
can be removed from the pins that they are
mounted on. The primary gear, which turns all
the others, is fixed to the shaft of the motor.

Front upper arm
Parts supplied:
A Front upper arm
B Ball-headed screw
C Pins
D Bearing (large)
E Bearing (small)
F Locknut
The parts supplied with this stage are components for the front suspension. The front upper arm, ball-headed
screw and locknut are identical to those provided in Stage 4, and the bearings are the same as those supplied
with Stage 8. All of these parts can be used on either side of the model. The parts supplied with Stage 21 – the
rear driveshaft, stub axle, drive pin, hexagonal drive washer and flanged nut –aren’t actually specific to the
rear suspension and so they can also be used on the front wheels. Therefore, in this stage, you can complete
the suspension for the left front wheel by using a ball-headed screw, locknut and pin, all supplied with this
stage, plus the upper arm and hub carrier assembly from Stage 4 and the parts from Stage 21.
1 Prepare the ball-
headed screw, locknut
and one of the pins. You
will also need a
screwdriver and two
Allen keys, a 2.5mm
and a 5mm.

assembly, along with the parts
from Stages 4 and 21, as shown.
3 Insert the ball-headed screw
into the bottom hole of the
hub carrier.
4 Insert the locknut into the
same hole as the screw, with the
flat side facing out. Screw the nut
into the hole, leaving it slightly
loose so that the ball-headed
screw is still able to move.
5 Insert the smaller bearing into
the centre of the outer face of the
hub carrier. Then insert the larger
bearing (arrowed) into the centre
of the inner side of the hub carrier.

driveshaft into the stub
axle and the other into
the cup joint on the
left-hand side of
the differential.

1 For this assembly stage, you will need needle-
nose pliers and all the parts of the servo saver,
except the screw and the inner shaft. You may need
some water pump pliers to compress the spring.
2 The two main components of the servo saver
are identified by the letters A and B. Combine the
two parts by engaging the V-shaped sections of
their circular parts.
With this stage, you receive the servo saver, which is a key part of your model’s steering
mechanism. The spring absorbs the energy produced by sudden movements of the wheels,
caused by uneven track surfaces and collisions, and so protecting the internal components of
the servo from possible damage.

4 Place the spring onto the
shaft so that it rests against the
E-ring. Then place the servo saver
onto the shaft, with part B facing
the spring.
5 Push the servo saver down,
compressing the spring. You may
find this easier if you use water
pump pliers.
6 Insert the second E-ring into
the groove at the other end of the
shaft, above servo saver A.
7 Use pliers to clip the E-ring
into the groove, securing
all the parts of the servo saver.
8 Here’s how the servo saver
should look at the end of this
stage. Keep the screw and the
inner shaft for a later stage.

The parts supplied with this stage are the air filter, its element, which is made of sponge, and
a bottle of air filter oil with which to moisten the sponge. The filter, an important part of your
model, will be fitted to the intake duct of the carburettor. Its oiled sponge element will
prevent particles of dirt from being sucked into the engine.
1 Place the new parts on a paper towel, as
shown. The towel will soak up any spilt oil.
2 Apply several drops of oil to the top and bottom
of the sponge fi lter element.

side of the fi lter as well.
4 Squeeze the sponge to make
sure that the oil penetrates it
thoroughly.
5 Dab away any excess oil with a
paper towel.
6 Insert the sponge into the
filter. There is a lip in the filter
that will hold the element in
place, so make sure that the top
edge of the sponge is tucked
underneath it.
7 Here’s how the air filter will
look with the sponge in place.
The air filter can now be fitted
to the carburettor.
8 Later on in the assembly
process, you will fi t the air fi lter
onto the carburettor, as shown.

Brake discs
The parts provided with this stage are your model’s front and rear brake discs, which are fi tted just to make the
model look more like the real Huracán – they don’t actually function, and the model’s actual brake is mounted
directly onto the transmission. At fi rst glance, all four discs look the same, but in fact there are some small
differences between the front and rear discs. Compare the distances between the mounting posts on the inner
sides of the discs (see photograph for Step 3): this distance is greater on the rear discs than it is on the front ones.
In this stage, you will fi t both of the front discs and one rear disc.

3 To identify the front and rear
discs, compare the distances
between the mounting posts. The
distance between the posts on a
front disc is less than the distance
between those on a rear disc.
4 Use 2 x 5mm screws to tap the
six holes in the posts on the rears
of the discs.
5 Insert the posts on the inside
of the front disc into the matching
holes in the front left hub carrier.
Then tighten a 2 x 5mm screw
into each of the indicated holes.
6 Fix the rear brake disc onto the
right rear hub carrier in the same
way. When fitted to the model, the
caliper should be facing the front.
7 Now fit the second front brake
disc to the right front hub carrier.
When fitted, the caliper will face
towards the rear of the model.
8 The three hub carriers should
now look like this, with the discs
mounted. Keep the unused
disc and screws safely until you
assemble the left rear hub carrier.
