SAFETY NOTES
• RC model helicopters aren’t toys! The rotor blades rotate at high speeds. Improper use can lead to
potential risks and serious injuries. It is mandatory that general safety rules in dealing with RC
models as well as local laws and regulations are observed. Further information can be found at
model aviation clubs in your area or model airplane organizations.
• Take care of your own safety as well as the safety of others in your environment when using our
product. Fly only in free areas, far away from other people. Never use RC ight models in close
proximity to residential areas or crowds. Do not y above people. Due to a variety of reasons RC
model aircraft may crash, such as poor maintenance, pilot errors or radio interference, resulting in
serious accidents. The pilots are fully responsible for their actions and for damage caused by the
operation of their model aircraft and injury.
• Read the following instructions thoroughly before using NANOBEAST the rst time and carefully
adjust the system according to the given instructions. Take enough time and check every step for
correctness. Also pay attention to a proper and awless mechanical construction of your model
helicopter. An incorrectly adjusted system can cause severe accidents and damage to the model.
• RC models consist of many electronic precision components. It is important to keep the model away
from moisture and other foreign substances. If the model is exposed to moisture of any kind, this
can cause malfunctions and lead to crashes. Never y in rain or extreme Humidity!
• When operating the helicopter with NANOBEAST pay attention to a suciently dimensioned and
loadable receiver power supply. Due to the direct linkage of the rotor blade holders to the servos,
increased forces let the power consumption get extremely high compared to a helicopter with a y
bar and rotor head mixer!
• Do not expose the NANOBEAST to extreme temperature uctuations before and during operation.
Allow some time for the electronics to acclimatize before turning it on.
• The NANOBEAST consists of highly sensitive electrical components that may fail under strong
vibrations or electrostatic discharges. Should you have such factors on your model, the use of the
NANOBEAST must be stopped until the external inuences were eliminated.
• When operating electric models with„single-line“ receivers, it is important to ensure that during the
adjustment work the electric motor can’t be started inadvertently. Do not connect the electric
motor to the motor controller or remove the motor from the main gear before performing the
adjustment work. Also make sure that the motor does not start if the transmitter unit fails (e.g. by
using the failsafe function of receiver and NANOBEAST).

II
• The NANOBEAST PROEDITION comes with the AttitudeControl function (optionally available horizontal
stabilization) which serves as a ight aid for beginners by restricting the freedom of movement of the
helicopter. However, this does not ensure that the helicopter can be always own safely! Due to
incorrect control inputs the helicopter may crash anyway, even when using AttitudeControl. In addition,
the helicopter can drift away from external inuences and it is not guaranteed that the articial horizon
of the device will stabilize the helicopter in every situation. By external inuences like strong
temperature uctuations or vibrations the sensors may produce false readings which will falsify the
position calculation of the system. It is not guaranteed that the system will always be working correct
under any circumstance. The pilot is responsible for the control of the helicopter and thus for the use of
the helicopter system. Also note that the system will not keep the helicopter in absolute place for
technical reasons. The unstable tendency of a helicopter will cause the model y away in a certain
direction. By external inuences such as wind or similar this eect can be even stronger. In addition,
there are measurement inaccuracies of the sensors, which can falsify the orientation. Make sure you’re
always able to turn o the system and take over complete control of the helicopter.
• Contact an experienced model pilot who will advise you on how to control and handle model
helicopters. A ight training by using a model ight simulation on the PC can help to get started in the
air model sport. Contact the local retailer for technical advice or in case problems arise during operation
with our product.
• The AttitudeControl rescue function (optional) is designed to facilitate the ying of model helicopters.
Control can be temporarily passed to the system if the pilot loses his orientation. Using the built-in
articial horizon, the system can bring the helicopter in an almost horizontal position, so the pilot gains
time to reorient himself. Anyhow, it can’t be guaranteed that the model will do so under any
circumstance. Depending on the current attitude and speed and depending on how quickly the
AttitudeControl is turned on, the model may crash nevertheless. Be sure to follow the general safety
rules for handling RC models. The pilot is responsible for the control of the helicopter and thus also for
the use of the system. He always has to be able to turn o the system and take over full control of the
helicopter.

Dear customer,
We congratulate you on your purchase! NANOBEAST is a control unit for small and very small RC model
helicopters without mechanical fly bar. The integrated gyro elements stabilize the helicopter as much as
possible, so that it’ll only follow the control commands of the pilot. The steering feel can be tuned easily from
tame to extremly agile. Thus, the model can meet almost any requirements of the pilots, no matter if you’re a
beginner pilot or 3D aerobatic professional.
By paid firmware upgrade the system can be extended to „PROEDITION“. This offers additional functions
like AttitudeControl for position stabilization and rescuing the model in difficult positions, as well as a bank
switching that allows to switch between different parameter sets in flight.
For basic setup and tuning of the system a computer (Windows / mac) or smartphone/tablet (iOS / Android)
with Bluetooth LE is required. Depending on the technology used, a USB2SYS (for computer) or BLE2SYS (for
Smartphone / Tablet) interface is required as additional accessory.This is not included and must be purchased
separately! The configuration then takes place via the StudioX Software, which is offered for free download:
This manual is a short guide to getting started. The operation of the StudioX software and configuration of
the helicopter is explained by references in the software itself and via web links. Detailed instructions for
configuring the helicopter, as well as for installation and use of the software additionally can be found at:

Supported receiver types / transmission protocols
• SRXL: JR® XBus (Mode B), Multiplex® SRXL (V1+V2), Jeti® UDI, Graupner/SJ® HOTT SUMD, Spektrum® SRXL
• Futaba® SBUS
• Single satellite (Spektrum® DSM2 / DSMX, JR® RJ-01 DMSS)
• Jeti® EXBUS
• ALIGN/FlySky iBus
• PPM serial signal (SPPM)
Attach the receiver to the helicopter and make sure that the cables and antennas will not get into rotating parts. Plug the
motor controller into the connection [1] for BEC power supply. Pay attention to maintain the correct polarity! Also make
sure the BEC voltage is in the range of 4.8 - 6.0 volts!
2. RECEIVER CONNECTION
Receivers with serial signal output transmit all control commands / channels by one wire. Connect the signal output from
the receiver with the signal input DI on the NANOBEAST (using the enclosed patch cable). If you use a SPEKTRUM® or
JR® single satellite, you can plug it into the SAT socket directly. In this case, use the cable supplied by the manufacturer (the pin
assignment at the SAT connection corresponds to the Spektrum® standard).

successful bind, remove the bind plug. The JR® RJ01 single satellite can be bound directly using the transmitter only. The
satellite will automatically go into bind mode when powering on the receiver before switching on the radio.
To bind the other types of receivers, follow the instructions of the manufacturer!

3. PREPARING THE TRANSMITTER
For safety reasons, remove the motor from the main gear during adjustment! In addition, disable the motor
channel using the autorotation switch (Throttle HOLD), so that the motor does not start when the thrust stick is moved.
No mixing functions must be active on the channel outputs. In particular, disable the mixing of the swashplate servos in
the radio. Also disable all unnecessary control channels. In the basic configuration only collective, aileron, elevator, rudder,
motor and a channel for the gyro is required.
Create a new model memory in your remote-control transmitter. It should provide multiple flight modes in order to control
engine, collective and gyro in different flight situations.
Only the pitch channel is
allowed to be controlled,
if thrust stick is moved.
The same applies to
aileron, elevator and
rudder.
Each control function must serve exactly one servo output. The servo travel must be at 100% and no trimming must
be used. Do not change the pitch curves for the adjustments. The throttle curves and settings of the motor channel can be
adjusted according to the model. However, for the basic setup of the system you should be able to block the motor channel!

4. STUDIOX
The NANOBEAST has a serial interface marked with the letter [SYS]. Use a standard servo cable to connect this
port with your USB or Bluetooth interface (sold separately). Watch out for correct polarity! Note that the interface
does not supply the NANOBEAST with power. The supply comes from the BEC of the motor controller, which is
connected to the connector [1].

Automatic detection of the remote-control system
In order to recognize the connected receiver type, the remote-control transmitter must be switched on and bound to the
receiver. Also make sure that the default setup of the transmitter was performed as described in chapter 3. Press SCAN to
start the search. The colour of the Status LED and in the display indicate which receiver type is currently being searched for.

Assignment of the control functions
As soon as the corresponding type has been detected, a query opens on how the function assignment should be performed.
Here you have the choice between loading a PRESET or the manual assignment (if you later learn the receiver type again, you
can also skip the function assignment without change). The preconfigured function assignments depend on the recognized
signal protocol and remote-control system. These are as follows:

ATTENTION: For failsafe setting, the throttle output [1] is active. So the motor could start when the throttle is
in the wrong position! If you are not sure which position is the right one or in case you want to program the ESC at this
point using the throttle stick, remove the motor from the main gear for safety reason.

In case the preset does not match to your radio system or you have another switch assignment wishes, you can train the
functions in sequence. Choose TEACH and then move the sticks / switches according to the display in the app. Note that you
must always only move one channel at once. Otherwise, NANOBEAST can‘t recognize which channel you want to use for
this function. This applies in particular to the throttle and collective pitch channel, which are usually controlled simultaneously by
the thrust stick in helicopter models. To learn these two functions separately, block the motor channel (i. e. with the autorotation
switch) to teach the pitch first, then release the throttle channel in order to be able to move the throttle afterwards (the pitch will
not be taken into account then, because it was already assigned to another function before).
Throttle failsafe
Last but not least, the failsafe position for the throttle has to be set. Bring the throttle channel to the position where the
motor is off. Then (after setting the function assignment) confirm the question to teach failsafe position with CONTINUE
and store the failsafe position by clicking SET at the bottom of the display

6. BASIC SETTING
Select the BASIC SETTING button to start with the basic helicopter setup (as long as the initialization sequence is not
finished, some buttons are locked in the overview screen!).
Device orientation
Set the installation position in StudioX so that it corresponds to the actual position of your NANOBEAST on your
helicopter. Then choose NEXT.
After initial power up or after finishing the receiver setup, wait until the initialization sequence is completed.
If you do not know the optimum or maximum drive frequency of the servos, never exceed 50Hz! The higher
the driving frequency, the better the flight performance of NANOBEAST. However, it must be ensured that the servos
are allowed to be operated with an increased drive frequency. Otherwise the servos could be damaged!
At WIKI.BEASTX.COM we have a list of data on the most popular servo types. Always use a pulse width
of 1520 μs, unless you use a special gyro servo which must be operated with reduced pulse width (only such servos
can be driven with extremely high frequencies up to 560 Hz!).
Control frequencies and pulse length of the servos
Set the drive frequency for the swashplate servos, the pulse width for the rudder servo, as well as the drive frequency for the
rudder servo at the appropriate points. Press NEXT to go to the next menu item.

Rudder servo and tail rotor
1. Connect the rudder servo to the output [2] of NANOBEAST and mount the rudder horn/servo cross as good as
possible at a 90 ° angle to the tail linkage rod. Adjust the linkage so that the tail slider is positioned correctly. Ideally, in the
90 ° position of the servo the slider is centered on the tail rotor shaft and the tail rotor blades have a slightly positive angle of
attack against the rotor torque in this position (e.g. 5° to the right on a helicopter with clockwise rotating rotor).
2. Carefully steer the tail using the rudder stick and check the direction of movement. When the stick direction is wrong, you
can reverse the rudder channel’s direction by using the servo reverse function of your transmitter.
Correct Wrong
Move rudder to the right Rotor must push the tail to the left,
the helicopter would turn right
Rotor pushes the tail to the right,
the helicopter would turn left
If the joystick controls the tail incorrectly, reverse the control
direction by using the servo revere function in your transmitter.
3. As soon as the servo moves in the correct direction when steering, the internal control direction of NANOBEAST
must be checked and adjusted if necessary: When the rudder stick is moved to the right, the Status LED must light up in blue
color and in the software must be displayed„right“. If the rudder stick is steered to the left, the Status LED must light up red
and the software must display„left“. If this is upside down, (i.e. red = right and blue = left) reverse the internal control direction
by selecting NORMAL or REVERESED.
Control frequencies and pulse length of the servos
Set the drive frequency for the swashplate servos, the pulse width for the rudder servo, as well as the drive frequency for the
rudder servo at the appropriate points. Press NEXT to go to the next menu item.

12
For most helicopters, the default setting of 120 ° can remain. The required swash plate mixing is mentioned in the helicopter‘s instruction
manual.
[1] = speed controler (ESC) [2] = rudder servo [3] =elevator servo [4] = roll servo left [5] = roll servo right
Be sure to follow the given order! Always set the correct servo and stick direction rst, then check the control
direction of NANOBEAST.The internal control direction does not change the servo direction! This only
serves to ensure that the gyro is moving the rudder to to correct direction. When checking and adjusting the
control directions, be very conscientious. A wrong control direction can lead to a crash!
4. Now set the servo limit. To do this, carefully move the servo to the end positions by rudder stick input and reduce / increase
the two values for right and left, so that the travel is adjusted optimally, i.e. the servo should move just as far as the tail pitch
slider is not binding and the servo is not blocked. If the tail rotor allows extreme tail pitch values, even less servo movement
can be useful!
5. If you move the rudder stick fully to the right or left, the Status LED on the NANOBEAST should be lit permanently
and the label „right“ or„left“ should be highlighted in the appropriate colour. When the stick doesn’t move far enough, the
message „Increase!“ will appear. In this case, increase the control deflection/servo travel in the remote-control transmitter
for both directions until the point at which the Status LED just changes from flashing to being lit permanently and the label
„OK“ is shown in the software when the stick reaches the maximum position. Note: Do not set the servo travel too large. If
the LED lights permanently long before the maximum stick position is reached, reduce the servo throw in the transmitter
accordingly.

Swashplate mixing
For most helicopters, the default setting of 120 ° can remain. The required swash plate mixing is mentioned in the helicopter‘s instruction
manual.
Never use the swashplate mix of the remote-control transmitter, even if the helicopter requires an electronic
mixing! Disable any kind of mixing of the swashplate servos in the transmitter. Choose a mechanical mixer (often referred
to as„normal“,„H1“ or„1 servo“) if applicable. Each stick of the transmitter must drive exactly one control output. Only
NANOBEAST is responsible for the swashplate mixing!
Then connect the servos to the outputs [3] to [5] as shown below. With electronic mixing the two roll servos connect at [4]
(= left) and [5] (= right). On mechanically mixed helicopters (mCCPM), the roll servo connects to [4] and the collective pitch
servo to [5]. The elevator servo is always connected at port [3].

When laying out the wiring make sure that it rests on the NANOBEAST without tension. Lay it out in a loose
loop and fasten it after approx. 5 - 7 cm at the chassis of the model. Don’t use shrink tube or fabric hose in the
immediate vicinity to the point where the cables are plugged into NANOBEAST. This makes the cables sti and
inexible and can cause vibrations being transferred to NANOBEAST.

If the servos are perfectly trimmed, adjust the linkages
according to the instructions of the helicopter so that the
swash plate sits in the middle of and horizontal aligned
with the main rotor shaft. In this position the rotor blades
must have 0 degrees of pitch. Work your way from the
bottom up. Adjust the lower servo linkages rst, making
the swashplate being perfectly aligned, then adjust the
pitch linkage rods.

If applicable, make sure the swashplate driver is aligned
correctly, so that the arms are horizontal and the linkage
balls are positioned in one line with the connection joint
of the rotor blade holdersat the 90 degrees position.
Linkage balls at inner ring
and at blade holders in one
line to each other
Alignment of the swashplate servos
In the next step we trim the servo centre positions so that the servo arms form a perfect 90 degrees angle with the linkage rods.
This is necessary because usually the servo drive trains are not accurate enough, so the servo arms fit as good as possible from
the beginning. If all servos are aligned properly, perform the basic mechanical setting of the rotor head, then press NEXT again.
Movement directions of the swashplate servos
Move the thrust stick and check whether the swashplate moves up and down. If this is not the case, you can reverse the
direction of movement for each servo individually in the StudioX app.
Make sure the pitch control direction is correct. This results either directly by correctly adjusting the servo directions, or you
can also reverse the direction of the collective pitch channel using the servo reverse function of the transmitter.

15
Note: You can’t reverse the individual servo directions with the reverse function of the transmitter! The transmitter only
gives control commands to NANOBEAST, but does not directly control the servos! When a control channel in the
transmitter is reversed, the function as a whole will be reversed, not the direction of one single servo (except when using a
mechanical swash plate mixture).
Throw adjustment of the swash plate
At the next setup step, the available (cyclic) control resolution is learned. For the adjustment procedure turn the rotor head
so that one of the rotor blades is parallel to the tail boom / to the longitudinal axis of the helicopter. Then attach a pitch
gauge at this rotor blade and set it to 0° (if you have correctly done the mechanical rotor head and servo setup before,
actually the blade must have 0° of pitch).
Now press the MEASURE button in the app. NANOBEAST will then move the swash into roll direction a little (the
actual direction is irrelevant). In this position, the rotor blades should show exactly 6.0° of pitch. If this is not the case, adjust
the given value in the app just until you get the desired amount of pitch.
0° 6°
If your heli is too small for a commercial pitch gauge, you can determine the pitch angle mathematically by folding the rotor blades by
90 degrees to the same side. At 0° of pitch, the blades should be parallel to each other when looking at them from the side.
In measuring position you can calculate the blade pitch from the resulting distance between the blades according to the formula:
angle = arcsine (distance / 2 / rotor blade length)
The required distance at which you get 6° of pitch calculates as follows:
distance = (sin 6°) * 2 * rotor blade length
Alignment of the swashplate servos
In the next step we trim the servo centre positions so that the servo arms form a perfect 90 degrees angle with the linkage rods.
This is necessary because usually the servo drive trains are not accurate enough, so the servo arms fit as good as possible from
the beginning. If all servos are aligned properly, perform the basic mechanical setting of the rotor head, then press NEXT again.
