CHAP. 2 BUILDING INSTRUCTIONS
In order to achieve a correct assembling of the model, we suggest to follow carefully the instructions.
2.1 Preliminary operations
Kit components control
Have a look at the components (see “PARTS LIST, MATERIALS AND TOOLS LIST” at page 3)
in order to easily identify them.
It is strongly suggested to trial fit all the parts “dry” before gluing them.
2.2 Fuselage
Inside the fuselage, the following components will be arranged:
— balancing weights;
— battery pack;
— V-tail pushrods;
— V-tail servos and ON/OFF switch;
— electrical connections for the wing servos;
— RX receiver.
Balancing weights
• Using some double adhesive tape, fasten
about 80 ~ 100 g of weights in the position
shown in figure 6; the weights have to form
a layer with no more than 10 mm of thickness (see figure 7).
Fig.6: Balancing weights position.
The layer will be used as a base for the battery
pack (see figure 7); the rest of the weights will
be added afterwards (during the model balancing) directly into the nose.
max 150 mm
Fig.7: Max. thickness of the balancing weights.
max 10 mm

Antenna
Because of the fuselage’s reinforcements and the elevator push-rods, both in carbon fiber, we
suggest to leave the antenna outside the fuselage.
For the best reception signal, the position we recommend is the one shown in figure 58.

2.4 Wing
The wing is divided in two panels, each one equipped with aileron and flap.
Flaps and ailerons servos are fitted into the wings. For this reason, each wing panel is fitted with
two rectangular housings where servos can be mounted. The use of flat servos (max. 13 mm -
better 11) with high torque (at least 20 Newton/centimeter) is foreseen.
The assembling procedure is identical (as in a mirror), for each wing panel.
Installing bushes for control horns
• Drill 4mm diameter holes on ailerons and flaps in the points shown in figure 59;
Fig.59: Position of the bushes.
WARNING! the center of the hole must be, at
least, 10 mm away from the leading edge of
the movable surfaces (see figure 60);
• using a file (about 5mm diameter, round
section), finish the holes;
Fig.60: Distance of the hole.
• insert the threaded bushes “BOCC” in their
holes from the top surface (see figure 61);
• with a drop of cyano or epoxy glue the bushes.

Electrical connection for the wing servos
The the wing servos connection needs just four wires to connect following the diagram shown in
figure 65.
+
~
~
_
Fig.65: Connection diagram for the wing servos (the same for the other wing).
• Insert the four wires into the wing up to the servos housings.
The positive (red) wire of flap servo can be connected with the same wire coming from the aileron servo; the same thing can be done also with the negative (black or other dark color) wire, but
(ATTENTION!) this can’t be done between the signal (orange or yellow) wires: the signal wires
must be always kept separate; in this way, only four wires (positive, servo flap signal, aileron servo signal, negative) will arrive to the connector “MPXM”.
Connectors
• Before soldering wires to the connector “MPXM”, insert the free tip of every wire into a 15 mm
long heat shrink sleeve of suitable section;
• solder the wires to the connector “MPXM” as shown in the diagram in figure 65;
• let every heat shrink sleeve slide on its soldering;
• using a hair drier (at least 1500W), direct the (very hot) air blow over the sleeves and let them
mould on the solderings.
Caution! When shrinking sleeves over joined wires, do not allow the hot air to `blast` over the wing or control surfaces - you will irreparably damage the wing!
• widen the rectangular hole on the wing root
until the connector will not perfectly fit;
• spread a little bit of epoxy around the connector and fasten it in the position shown in
figure 66;
• let the glue dry and repeat also on the other
side.

Flap servo
• Using side cutters, remove the RX connector of the servo;
• cut and strip, for a length of about 10 mm, the three wires coming from servo;
• strip the black and the red wire coming from
the wing for a length of 10 mm, but, WITHOUT CUTTING THEM;
• before soldering, insert the free tip of every
wire into a 15 mm long heat shrink sleeve of
suitable section;
• solder the end of the red wire, coming from
servo, to the skeined red wire coming from
the wing and do the same soldering the
black (or dark) wire, coming from servo, to
the black one coming from the wing (see fig-
ure 67);
Fig.67: Flap servo connections.
• cut and strip, for a length of about 10 mm, the end of the orange wire coming from the wing
and solder it to the end of the signal wire coming from servo; but, don’t touch the other sig-
nal wire (the one for the aileron);
• let every heat shrink sleeve slide on its soldering;
• using a hair drier (at least 1000W), direct the (very hot) air blow over the sleeves and let them
mould on the solderings.
Caution! - when shrinking sleeves over joined wires, do not allow the hot air to `blast` over the wing or control surfaces - you will irreparably damage the wing!
Aileron servo
• Using side cutters, remove the RX connector of the servo;
• cut and strip, for a length of about 10 mm, the end of all the three wires coming from servo;
• cut and strip, for a length of about 10 mm, the end of all the three wires coming from the wing;
• before soldering, insert the free tip of every wire into a 15 mm long heat shrink sleeve of suitable section;
• solder the end of the orange wire coming
from the wing, to the end of the same wire
coming from the servo; solder the end of the
red wire coming from the wing to the red one
coming from the servo and do the same soldering the black (or dark) wire, coming from
servo, to the black one coming from the win
(see figure 68);
• let every heat shrink sleeve slide on its soldering;
Fig.68: Aileron servo connection.
• using a hair drier (at least 1000W), direct the (very hot) air blow over the sleeves and let them
mould on the solderings.
Caution! - when shrinking sleeves over joined wires, do not allow the hot air to `blast` over the wing or control surfaces - you will irreparably damage the wing!

Servos test
Before to mount the wing servos, will be better to check the connections:
• connect servos (and ON/OFF switch) to the receiver following the diagram shown in figure 88
at page 39;
• check that the ON/OFF switch is in position OFF, then plug the battery pack;
• switch on the transmitter before, then the receiver;
• check the correct link of each servo to the transmitter;
• adjust the central position of the servo horns;
Note: eventually, the servos horn central position can be mechanically adjusted just removing and reinserting the
horn in a different position.
• switch off the receiver before, then the transmitter.
Further adjustments will be done during the model settings.
28
Mounting servos inside the wing
For each wing servo “SERW”:
• shorten the horn of (at least) two holes (see
figure 69);
Fig.69: Shorten the horn.
• fasten the horn to the servo;
• remove protection film and apply the double
adhesive plate to the servo (see figure 70);
Note: we suggest to spread some “five minutes” epoxy
in order to better glue the servo to the wing”.

• insert the servo into the housing (the horn
must be on the EXTERNAL SIDE OF THE
WING and towards the trailing edge (see fig-
ure 71);
• press the servo to fasten it.

Servo covers
The wing servo covers are made from the shapes “CARS”.
From every shape, two covers can be made (left and right):
• take the distance (1) from the external edge
of the servo housing and the servo horn
(see figure 76);
• take the dimensions (2 and 3) of the external
servo housing edges;

• taking as reference the center of a bulge of
the shape “CARS” (see figure 77), carry the
taken measure (1) from the external edge of
the servo housing and the servo horn;

• from that point, using a pencil, draw a rectangle with the same dimensions (2 and 3) of
the external housing edge taken before;

Fig.77: Shape for two servo covers (left and right).
• symmetrically, make the other servo cover from the other half of the shape;
• repeat the procedure for the other shape in order to obtain the four servo covers required;
• using a file, finish every cover fitting it to the
corresponding housing;
• using some thin double adhesive tape, apply
the inner covers (see figure 78).
Note: the outer covers will be applied to the wing just after the lateral model balancing that will be described later.

3.2 Model balancing
CG
The CG of the model must be placed at 83 ~ 88 mm from the wing leading edge at the wing root
(see figure 86).
83 ~ 88 mm
Fig.85: CG position.
Note: You may in a second time move it a little backwards if you feel (and if you are a real good pilot...).
Checking and correcting the CG position
• Mark with a piece of tape the CG position under the wing and hold the model with your fingers:
the model must stay level;
• remove or add lead to front until satisfied.
Note: the model must be complete with all his part including the nose cover during the CG check.
• once positioned the CG in the correct point, secure the lead used to balance, in the nose, so it
cannot move again.
Checking and correcting the lateral balance (both versions)
Before to apply the outer servo covers, we recommend to check (and eventually correct) the
model lateral balancing.
Checking
• Lay the model on a flat hard surface;
• try to keep the model flat rising the wing that is in touch with the ground;
37
X-MODELS - Blade XL & SUPER BLADE
• gently leave the model alone (see figure 86);
Fig.86: Checking for lateral balance.
• repeat this more times.
Correcting
If the same wing half drops all the times:
• add some lead pellet to the lighter wing (you can place the lead in the servo hole) until satisfied (usually a few grams do the job);
• repeat the test (see “Checking” at page 37).
If the wings halves are dropping randomly, the model is ok; in this case:
• apply the servo covers (see “Servo covers” at page 31).
How to add ballast
Flying in the wind (dynamic fly) requires the addition of ballast in order to increase the stability of
the model in turbulent air.
The ballast must be put around the CG (in this way the CG will not change too much); for this
reason, the carbon fuselage has been equipped (in its lower part) with a cylindric housing for the
ballast (see figure 87) approx. 280 long and with a diameter of 27.5 mm.
The housing can lodge ballast for an amount of approx. 1500 grams. The best shape for the ballast is one or more crop ends (approx. 25 mm long) obtained from a lead bar of proper section
(approx. 30 mm).
A less amount of lead (es. 500 g.) must be
firmly inserted in the center of the tube; for this
reason, wooden spacers must be inserted into
the tube either in front than behind the lead.
When fitting single ballast `slugs`, and not filling up
ballast tube fully, ensure that the wooden spacers
are positioned either side of ballast slugs, to keep
the ballast in the centre of the ballast tube and on
the CG!
Fig.87: Ballast tube.
Once inserted the ballast, we recommend to accurately check the CG position.
