X-3D-BL User’s Manual
1 Introduction
Congratulations! You have just bought a powerful
high-end model aircraft kit!
Please read this manual thoroughly until the end befo-
re you start assembling your X-3D-BL and stick with
the proposed chronological order. Warranty is void if
this manual is not strictly followed.
WARNING!
Assembling the X-3D-BL requires some experience
with building R/C models and soldering. If you do
not feel like you could do this on your own, please
make sure you get some help from a person with the
experience required. If cables are connected falsely
hardware can be destroyed. WARNING! Such cases
are not covered by warranty!
A motorized model aircraft is not a toy! It should only
be flown by adults. Improper assembly or operating
can lead to severe injuries and / or damages. Trouble
with your remote control due to interferences can
occur any time without prior notice. Sometimes, a
model aircraft can suddenly become uncontrolla-
ble due to a failure of any component, including
mechanical parts and electronics. In this case, the
model can rapidly move towards any direction. Make
sure you always keep a safe distance to people,
animals, obstacles or things of any kind, traffic roads,
etc.. There are country-specific laws regulating the
operation of model aircrafts that definitely have to
be obeyed. Furthermore, we strongly recommend to
effect a liability insurance for model aircrafts. The
manufacturer and your dealer of the X-3D-BL do
not have any influence on, nor can they monitor the
correct assembly and proper operation of your model
aircraft. Always be aware of the dangers mentioned
above and act accordingly. There is no liability of the
manufacturer nor the retailer at all, as far as legally
approved.
Our products are hobby-products and solely meant for
usage in non-commercial ways. It is not allowed to
use them for any commercial or military purposes.
Using any of our components for larger scale flying
objects is explicitly forbidden.
SUBJECT TO CHANGE WITHOUT NOTICE.
1.1 System overview
1.1.1 X-CSM
The X-CSM is the mechanical frame of the X-3D-
BL UFO. The booms, which are made of a rigid
carbon fiber-balsa wood sandwich material, can be
replaced individually. The central unit of the frame
called the ”X-CSM Core” is made of light weight
laser-cut magnesium parts. Being built out of these
state-of-the-art materials the X-CSM is a very robust
high-tech basis for your quadrotor aircraft.

X-3D-BL User’s Manual
1.1.2 X-Base
The X-Base is the central control unit which is
connected to and communicates with all active
elements of the X-3D-BL. Next to the battery, the
motor controllers, the X-3D gyro and the receiver
you can also connect several LEDs to the X-Base to
give your X-3D-BL a unique fancy look.
An LED connected to the ”Front-LED” Pads on the
bottom side of the X-Base will always be on as long
as the X-3D-BL is turned on. Such an LED can be
mounted to the very front of your vehicle to make it
easier for the pilot to know where the front side is.
1 BL-controllers / brushed motors (+)
2 BL-controllers (-)
3 Brushed motors (-) Left/Right/Back/Front
4 PPM-Receiver Input (-) (+) Signal
(from lower to upper connector)
5 LEDs (-) Left/Right/Rear/Front
6 LEDs (+) 5V
7 Power connector, (+) and (-) marked on the
upper side of the board
The key below the power connector (7) turns the
X-3D-BL on and off. A short press is enough to turn
the vehicle on. To turn it off the key has to be pressed
for at least 200ms.
The ”brushed motors” connectors of the X-Base (3)
are not required as the brushless motors are driven by
independent controllers, and thus the connectors can
be used to drive peripherals like for instance a night-
flight kit. Connector ”L” is switched on and off by
R/C channel 5, connector ”R” by R/C channel 6. The
connectors can sink currents up to 5A if they’re ena-
bled. That means that the (-)-input of a peripheral has
to be connected to the ”L” or ”R” pad and the (+)-
input has to be connected to (+) (connector (1)). Be
aware that in this configuration your peripheral will
be supplied the whole battery voltage. If this not what
you need make sure you use a suitable voltage regu-
lator.

X-3D-BL User’s Manual
1.1.3 X-3D
The X-3D is the sensor unit of the X-3D-BL. With
three piezo-gyros and highly optimized control
loops it does the actual flight/attitude control. All
parameters influencing the in-flight behavior can be
tuned by connecting the X-3D to a PC using the USB
adapter that came with your X-3D-BL. Once you are
on the field for flying you can select four different
parameter sets using two jumpers.
LED patterns shown by the X-3D
•red blinking: Initializing or at least one motor
not detected
•yellow+green: No reception or playing startup-
melody
•green: Ready to fly
1.1.4 X-3D-FunPilot
The X-3D-FunPilot is the new high performance
sensor unit of the X-3D BL UFO. Equipped with
three piezo gyroscopes, a pressure sensor and highly
optimized control algorithms, the X-3D-FunPilot
takes care of the flight control of the UFO. All
important parameters of the X-3D-FunPilot can be
set with the PC software and the X-USB module.
Four different settings can be stored onboard and can
be selected by the RC on the flight field
LED patterns of the X-3D-FunPilot
•red: Initialisation
•red/yellow blinking: X-Base or X-BL motors
not detected
•red/yellow and green blinking: No RC recepti-
on and ne setting selected
•yellow and green blinking: No setting selected
•yellow blinking/green: Ready for flight
•yellow blinking: X-Base is in setup mode
•yellow/red: trim reset
•gelb: trim saved
1.1.5 Motors
The X-BL-52s motors by HACKER Motors Germa-
ny are custom-built for the X-3D-BL. The motors are
perfectly suited for the application in this vehicle.
www.x3d-shop.de - 6 - www.asctec.de

X-3D-BL User’s Manual
1.1.6 X-BLDC brushless motor
controllers
Every motor is controlled by an independent X-
BLDC brushless motor controller. The controllers are
highly optimized for the X-BL-52s motors and thus
ensure the highest efficiency possible. Please note that
for this reason the controllers might not work with a
different motor type.
1.1.7 Optionally available: X-ACC
The X-ACC is a tiny add-on module, which gives the
X-3D-BL a totally different behavior. For using the
pressure height control with the X-3D-FunPilot, the
X-ACC module is neccessary.
Without the X-ACC the X-3D-BL is flying in the so
called Heading-Hold mode. The vehicle always tries
to keep its current orientation if there is no control
command. If you push a stick on your remote the
vehicle will turn in the associated axis. The further
you push the stick, the faster the X-3D-BL turns.
The X-ACC is a triaxial accelerometer. Using the ac-
celeration data the X-3D can compute the absolute
orientation of the vehicle in pitch and roll. As a conse-
quence, the helicopter is able to come back to a hori-
zontal orientation on its own. In the X-ACC mode you
command an absolute angle. The further you push the
pitch or roll stick, the bigger the tilt-angle of the X-
3D-BL. If you leave the stick centered the helicopter
will come back to horizontal. In this mode you are
not able to do loops or flips, however, hovering and
all 2D-maneuvers are much easier to do. The X-ACC
is also a great help for beginners! You can switch bet-
ween the Heading-Hold and the X-ACC mode during
flight using a switch on your (>4 channels) remote
control.
1.1.8 Optionally available: X-3D Mag
The X-3D Mag is used for stabilysing the yaw axis to
hold an absolute angle. By using a tilt compensation
algorithm the X-3D BL Ufo holds it’s desired heading
in the X-ACC and X-ACC-height mode at any time.
This makes it also easier for beginners to get in touch

2 Assembly
2.1 Before you start
Familiarize yourself with the kit and check if all parts
are included. All parts are subject to quality assurance
during production and packaging. We hope that you
are contented with the quality of all components. If a
part should not be totally o.k. we are willing to amend
or exchange the affected part.
2.2 Assembly of the X-CSM
frame
The whole assembly process of the X-CSM is des-
cribed below. Every important step is depicted in a
photograph. Please read the whole section before you
start assembling your frame in the recommended or-
der.
2.2.1 Preparing the base of the
X-CSM Core
Press the rubber bushings in the respective holes and
glue in the brazen bushings using for example Super
Glue.
.
2.2.2 Lateral frame parts of the
X-CSM Core
Plug the lateral magnesium parts into the planned
slots. Turn them until they engage.
www.x3d-shop.de - 10 - www.asctec.de

X-3D-BL User’s Manual
2.2.3 Upper side of the core
Plug one of the two magnesium plates into the slots
inside the lateral magnesium parts on the upper side
of the core. In this case, orientation does not matter.
Press one of the small CF plates from above over the
lateral parts, until the CF plate touches the magnesi-
um plate completely. Slide a plastic screw through the
central hole and fix it using a plastic nut.
2.2.4 Adding the booms
Plug the booms onto the lateral parts of the Core from
below and slide them up. If a lot of force is required
to do so, it is very likely that upper and lower side
of the booms have been confused. Marking: The drill
holes to attach the motor controllers are on the lower
side of the booms.
After that, the booms have to be secured with two pla-
stic screws each. The screws go into the outer two ho-

X-3D-BL User’s Manual
les from top and are fixed with plastic nuts from be-
low. Attention! One side of the CF baseboard is meant
for mounting the R/C receiver. Please make sure that
the orientation is as seen in the following photograph.
The R/C receiver goes on the rear left side of the fra-
me (top view!).
Put the solid CF plate on the booms and fix it with
four plastic screws which go into the previously
mounted brazen bushings.
2.2.5 Lower side of the Core
As seen in the picture, the two magnesium bars have
to be covered by heat-shrink, a silicon hose, rubber
or something similar to protect the battery. Their ori-
entation has to be perpendicular to the R/C receiver
mount.
Slide the O-rings over the lateral magnesium parts as
seen in the picture.
After that, the second magnesium plate is to be placed
in the lower slots of the lateral parts. The orientation
has to be as seen in the following photograph.
The second CF plate with slots in its corners has to be
slid over the lateral parts until it touches the magnesi-
um plate completely.
The two plates are now mounted together using a
plastic screw and a plastic nut.

X-3D-BL User’s Manual
Congratulations! You have just finished your X-CSM
Core!
2.2.6 Mounting a battery
The X-CSM Core offers a good protection for your
battery. However, the protection only works if the
battery is attached correctly. If this is not the case,
the battery can be damaged or even destroyed during
a hard crash. The battery can be mounted correctly
using for example a small wooden plate with a hole in
its center. Such a plate can be attached to the battery
using hook-and-loop tape. The hole will engage with
the plastic screw in the center of the Core’s bottom.
Make sure you add some material (e.g. rubber-tape)
to push the battery against the bottom of the Core. It
is important, that the wooden plate touches the lateral
parts of the core, such that the battery can not move
sideways.
Your X-CSM frame is now assembled completely!
Good luck with adding the electronics! :-)
2.3 Mounting the Electronics
2.3.1 Preparing the X-Base
The X-3D spacers have to be screwed to the X-Base.
After that, the spacers for mounting the X-Base itself
have to be fastened using four tapping screws. The
spacers will stick to the screws, even though they can
easily be moved up and down.
In addition, the battery cables have to be soldered to
the appropriate soldering pads. Make sure that the po-
larity is correct!
www.x3d-shop.de - 13 - www.asctec.de

X-3D-BL User’s Manual
2.3.2 Preparing the X-BLDC motor
controllers
Put two tapping screws into the holes and fasten them
using the 4 mm plastic spacers. Make sure the screw-
heads are at the controller’s side with the red cable
attached. Repeat this procedure with all four control-
lers.
2.3.3 Positioning of the X-Base
Put the battery cables through the rubber bushing next
to the receiver-mount. This will be the rear left side of
your X-3D-BL.
2.3.4 Mounting the X-BLDC motor
controllers
Screw the motor controllers to the respective holes in
the booms. Do this by turning the screws alternately
turn by turn, until the spacers touch the boom. Thus
you will not bend the controller boards too much.
The power cables of the controllers are still unconnec-
ted at this point.
www.x3d-shop.de - 14 - www.asctec.de

X-3D-BL User’s Manual
2.3.5 Mounting the motors
Place the motors on top of the booms as seen in the
following picture, and fasten them using 4 plastic
screws for each motor. Make sure you use the 8 mm
screws which came with the motors, and not the lon-
ger ones used for the X-CSM.
Slide a piece of heat-shrink (about 1 cm) over each
motor cable. Therefore you have to cut the heat-
shrink which came with your motors and controllers
into 12 pieces with about the same length. Solder the
motor- and controller cables together and isolate them
using the heat-shrink and a hot-air-gun. It does not
matter which controller cable you connect to which
motor wire, as the turning direction of each motor can
be adjusted using the PC-Software later on.
2.3.6 Wiring
The black and blue data cables (I2C) have to be put
through the rubber bushings on the front left and the
rear right side of the X-CSM core.
After that, the controller power cables have to be put
through the bushings. Two sets of cables go through
the so far unused rubber bushing, and one set of ca-
bles goes through each of the bushings with the data
cables already inside (see photograph).
www.x3d-shop.de - 15 - www.asctec.de

X-3D-BL User’s Manual
Solder the red cables to the soldering pads at the rear
right side of the X-Base marked with ”+”. The ca-
bles’ order does not matter. All cables have the same
length, which has been chosen such that non of the
cables must be shortened nor extended.
Solder the black cables to the soldering pads marked
with ”-”. Again, their order does not matter. None of
the cables has to be shortened nor extended.
Connect the black and blue data cables to the motor
controllers ...
... and to the X-Base.
2.3.7 Mounting the ACT-Receiver (35
or 40 MHz)
The 4-pin connector for the ACT-Receiver is positio-
ned at the front left side of the X-Base. The receiver
is connected using the 4-wire cable. After that, it has
to be glued to the receiver mount at the rear left side
of your X-CSM using double-sided tape.
www.x3d-shop.de - 16 - www.asctec.de

X-3D-BL User’s Manual
2.3.8 Mounting a different receiver
The X-3D-BL was designed for the European market.
Unfortunately, ACT-Europe does not offer any 72
MHz receivers with the convenient digital interface
used in the X-3D-BL. To enable people in countries,
where 35 and 40 MHz R/C models are not allowed,
to fly the X-3D-BL as well, we implemented an
interface for a standard PPM-receiver (cf. 1.1.2,
connector no. 4). However, as a normal receiver
has an output multiplexer to distribute the incoming
signal to the independent servo control channels, you
have to modify the receiver to make it compatible
to the X-3D-BL. Be aware that you do such a
modification at your own risk! By trying to modify a
receiver its warranty will be void!
Almost any receiver can be used, as long as you are
able to find and to access the combined PPM-Signal
before it is split up into several channels by the output
multiplexer. A digital storage oscilloscope is a handy
tool to find the signal.
Here is an example of how to modify the ”BERG Mi-
crostamp 4” full range receiver. This receiver is cast
in some soft plastics. The combined PPM signal can
be found at the outer most pin of the PIC processor.
To reach it you have to use a cutting knife to carefully
cut away a little part of the molding material. Careful-
ly solder a wire to the outer most pin of the processor
as shown in the following photograph.
Then connect the GND and VCC wires to any of the
four GND and VCC connectors:
Finally, connect the cables to connector no. 4 of the
X-Base exactly as seen in the next picture.
Please make sure you upload the ”X-Base Vx.x for
X-BL and PPM receiver.xbs” firmware as described
in 3.1.3.
2.3.9 Mounting the X-3D or
X-3D-FunPilot
The X-3D(-FunPilot) is simply plugged to the X-Base
and fastened using three screws. To do so, you have
to remove the top cover of the X-CSM Core.
www.x3d-shop.de - 17 - www.asctec.de

X-3D-BL User’s Manual
There is no additional cable required to transfer data
between the X-3D and the X-Base. Put the top cover
of the X-CSM back in place and fasten it using the
central plastic screw.
2.4 Last steps
2.4.1 Mounting the antenna
The antenna can be assembled as seen in the follo-
wing picture. Use the thinnest heat-shrink that came
with your kit to cover the lower end of the GFK stick
which will hold the antenna wire. Put a silicon hose
with a length of about 2 cm over it. Cut a piece of
about 3 mm length of the thick heat-shrink and use
the remaining (long) piece to cover the silicon hose.
Make sure that the heat-shrink covers the upper end
of the silicon hose and thus prevents it from sliding
off. Fix the antenna wire using a 3 mm piece of the
thick heat-shrink and wrap the wire around the stick.
The end of the antenna can be fixed to the stick using
a short silicon hose. This hose is also used to protect
the peak end of the antenna. Now you can simply sli-
de the antenna’s stand support over the top-screw of
the X-CSM Core. If you want, you can use a metal
screw instead of the plastic screw for more stabili-
ty. Alternatively, the antenna can be put on a longer
screw holding one of the booms, or it could be fa-
stened to one of the lateral parts of the X-CSM core
using two cable ties.
2.4.2 Preparation and mounting of
the propellers
The lower piece of the propeller center has to be re-
moved using a cutter. In addition, the hole has to be
extended using a 3 mm (1/9 inch) drill.
The propellers can then be slid over the axle and be
fastened using a plastic nut. Do not fasten the nut too
tight, as this would bend the propellers.

X-3D-BL User’s Manual
Please note that there are two types of propellers: One
pair of propellers is spinning clockwise, the other pair
is spinning counterclockwise. The Propellers spin-
ning clockwise must be mounted to the front and
the rear motor, whereas the counterclockwise rotating
propellers must be mounted to the left and to the right
motor.
To improve the durability of the propellers during a
crash you can optionally add a cable tie (e.g. 2.5 x
100 mm) as seen in the following picture.
2.4.3 Marking the front
As a pilot you always must know where the front of
your X-3D-BL is. To make this easily visible we re-
commend to attach some colorful tape to the front
boom. A little flag as seen in the following photo-
graph makes it much easier to identify the UFOs front
in any situation.

2.5 Optional: Integrating the
X-ACC
If you own an X-ACC please attach the spacer to the
X-Base using one of the M2-screws. To do so, insert
the screw in the drill hole in the X-Base and hold
it with one finger from below while you screw the
spacer onto it.
Plug the X-ACC into the socket on the X-Base and
fasten it using the second M2-screw.
2.6 Optional: Integration of the
X-3D Mag
Attention: The X-3D Mag can only be used in
combination with the FunPilot and the X-ACC
module!
The X-3D Mag has to be mounted on the car-
bon fibre panel as shown in the image. The riser PCB
has to look away from the CF panel and has to be
in the corner. Please use the nuts on the top of the
CF panel! A wrong orientation will lead to wrong
measurements and erratic behaviour!
Now connect the cable to the X-3D Mag and the
FunPilot, place the carbon fibre panel ontop of the
X-CSM as shown in the picture and mount the 3mm
top plastic screw as usal.
Attention: The X-3D Mag perfomance can be
affected by high current cables close to the sensors.
