SAFETY NOTES
• Radio controlled (R/C) helicopters are no toys! The rotor blades rotate at high speed and pose potential
risk. They may cause severe injury due to improper usage. It is necessary to observe common safety
rules for R/C models and the local law. You can gather information from your local R/C model club or
from your national modelers association.
• Pay attention to your own safety and the safety of other people and property in your vicinity when
using our product. Always y in areas away from other people. Never use R/C models in close proximity
to housing areas or crowds of people. R/C models may malfunction or crash due to several reasons like
piloting mistakes or radio interference, and cause severe accidents. Pilots are fully responsible for their
actions, and for damage or injuries caused by the usage of their models.
• Please read the following instructions thoroughly before the rst use of your MICROBEAST PLUS and
setup the system carefully according to this manual. Allow sucient time for the setup procedure and
check each step carefully. Watch for a mechanically clean and proper build of your helicopter. A wrong
system setup can lead to a serious accident and damage to the model.
• Radio controlled (R/C) models consist of several electrical components. It is therefore necessary to
protect the model from moisture and other foreign subtances. If the model is exposed to moisture this
may lead to a malfunction which may cause damage to the model or a crash. Never y in the rain or
extremely high humidity.
• When operating the helicopter with a MICROBEAST PLUS ensure there is a suciently large and stable
receiver power supply. Because of the direct coupling of the rotor blades to the servos, without the use
of a ybar mixer, the servos are exposed to increased actuating forces. In addition, because of the
intermediary electronic gyro system, the servos are driven more often than with traditional use. These
factors can make the power consumption increase a lot compared to a ybar helicopter. When the
supply voltage falls below 3.5 volts for a short amount a of time, the system will power o and reboot.
In this case a crash of the helicopter is unavoidable.
• Do not expose the MICROBEAST PLUS system to extreme variations in temperature. Before powering
up the system, wait some time so that the electronics can acclimatize and any accumulated
condensation is able to evaporate.
• The sensors of MICROBEAST PLUS consist of highly sensitive electromechanical components. These can
be damaged due to moisture or mechanical or electrical impact. Do not continue using this product, if
it has been exposed to such inuences, e.g. due to a crash of the model or due to overvoltage caused
by a defective receiver power supply. Otherwise a failure may happen any time.
• When operating electric helicopters make sure that the electric motor cannot start inadvertently during
the setup procedure. Particularly pay attention if using a single-line receiver and if the ESC is connected
directly to the MICROBEAST PLUS. We recommend disconnecting the electric motor from the ESC during
the setup procedure. Prior the rst usage please slide the motor/pinion away from the main gear, then
check that the motor does not to start inadvertently when the receiver is switched on.

• When operating the RPM Governor feature of MICROBEAST PLUS it is essential to ensure that the motor
cannot start by accident when making adjustment or performing preparations to start the engine.
Carefully read this manual and make sure you fully understand how the RPM Governor feature is
operated before making any adjustments. Also make sure the motor does not start when the radio link
is interrupted or when you switch on the transmitter initially. With electric driven models do not dock
the motor to the main gear unless all necessary adjustment procedures have been nished. Always
maintain sucient safety distance to the motor and other rapidly rotating components of the
helicopter.
• MICROBEAST PLUS with AttitudeControl can be used as a ying aid for beginners by limiting the
reaction of the helicopter to stick inputs and by stabilizing the helicopter with a electronic control loop.
However, this does not provide that the helicopter can always be own safely! By incorrect control
inputs the helicopter still may crash or be placed in a position in which the pilot becomes disoriented
even when using AttitudeControl. In addition, the helicopter can drift due to external inuences and it
is not guaranteed that the articial horizon of the device can stabilize the helicopter at any time and
recover from any orientation. Inuences such as temperature uctuations or vibrations may cause
incorrect results and distort the position calculation of the system in consequence. There is no
guarantee that the system will always work correctly. Only the pilot is responsible for the control of the
helicopter and thus also for the use of the system. Note that the system for technical reasons will not
hold the helicopter absolutely to the point. The unstable tendency of a helicopter will cause the model
to y in a certain direction even when using AttitudeControl. External inuences such as wind can
further strengthen this eect. In addition measurement inaccuracies of the sensors can distort the
position determination slightly. You must always be able to turn o the system immediately and be
able to take over full control of the helicopter.
• We suggest you to seek the support of an experienced helicopter pilot before you undertake the rst
ight of your model. Additionally, ight training with a R/C simulator can help make ying easier and
more enjoyable. Ask your local dealer if you need technical support or if you observe problems during
the usage of our system.
• AttitudeControl can help to facilitate ying of model helicopters by briey passing over control to the
system if the pilot becomes disoriented. By using the built-in articial horizon the helicopter can be
brought to a nearly horizontal position so that the pilot gains time to reorient. Thus, there can be no
assurance that the model is saved from a crash in general. Depending on the current attitude and the
speed of the model and depending on how fast the AttitudeControl is activated, the model may crash
before or while the system tries to recover. In addition, the helicopter can drift due to external inuences
and it is not guaranteed that the articial horizon of the device can stabilize the helicopter at any time
and recover from any orientation. Inuences such as temperature uctuations or vibrations may cause
incorrect results and distort the position calculation of the system in consequence. Strictly observe the
general safety rules for dealing with RC models and do not totally rely on the system. The pilot is
responsible for the control of the helicopter and thus also for the use of the system. You must always be
able to turn o the system immediately and be able to take over full control of the helicopter.

StudioX allows to edit, save and load the device setup by using a PC. Additionally it can
be used to register your device and aquire optional features. Also it allows to perform
very special setups like such as a virtual swashplate rotation for multiblade rotorheads.
To connect your MICROBEAST PLUS to the computer the optional available USB2SYS
interface is required.
StudioX can be downloaded from:

Dear customer,
thank you for purchasing our product.
MICROBEAST PLUS is a high-end flybarless system for RC helicopters that has been developed in Germany
using latest technology and setting high standards. This system can be used with nearly any size and type
of RC helicopters and besides using it as flybarless stabilization system it offers additional features that can
make flying helis even easier and comfortable.
To program MICROBEAST PLUS we consciously decided against using a tiny display that might be hard
to read or using an external programming device such as a smart phone or PC software. The „EasySetup“
concept allows to setup the helicopter in a very short amount of time and without the need of additional
devices which you might have forgotten at home when on the flying field. You can setup your helicopter
anytime and anywhere and you‘re ready for take off within a few minutes.
This Quickstart Guide is a clearly arranged guide that will lead you step-by-step through the basic flight
setup. Please follow this guide carefully and make sure to read the attached safety notes. For a detailed
instruction manual and a lot more details, tipps, tricks and notes about the product please visit
WIKI.BEASTX.COM
QUICKSTART GUIDE V4.1

1. HARDWARE INSTALLATION
You can position MICROBEAST PLUS flat or upright on the helicopter. The large socket must point to the front or to the rear of
the helicopter. The small white socket must be aligned with the longitudinal axis.
The sensor axis (housing edges of the device) must be aligned exactly parallel to all three rotation axis of the helicopter.
However, it is allowed to position the device offset from the rotation axis.
In summary there are 8 mounting orientations possible:
1. flat, sticker on top, socket pointing to front
2. upright, button up, socket pointing to front
3. flat, sticker showing to ground, socket pointing to front
4. upright, button down, socket pointing to front
5. flat, sticker on top, socket pointing to rear
6. upright, button up, socket pointing to rear
7. flat, sticker showing to ground, socket pointing to rear
8. upright, button down, socket pointing to rear
Use one of the supplied 3M gyro pads to stick the device to your helicopter. The device housing must not directly touch
the chassis of the helicopter. When connecting and laying out the servo and receiver wiring later onwards please make sure
the wires do not pass tension to the MICROBEAST PLUS. It is not recommended to bundle or tie down the leads close to the
MICROBEAST PLUS device.

HOTT SUMD, Spektrum® SRXL
• Futaba® SBUS
• Spektrum® remote satellite (DSM2/
DSMX)
• JR DMSS remote satellite (JR RJ01)
• PPM serial signal (SPPM)
Using a single remote satellite is only
recommended for 450 size helis or
smaller! For larger helis you may use a
SRXL compatible Single-Line receiver.
The illustrations are only
intended as examples! The
function assignment of the
transmitter determines which
channel on the receiver controls
which function.
Using a Single-Line receiver all channels/functions are transferred by one single connection wire. This allows to use even more
than 5 channels, i. e. for controlling the nitro RPM Governor, AttitudeControl function and/or additional servo output channels.
Always make sure the power supply is stable and dimensioned suciently for the intended application. If possible always
connect the power source directly to MICROBEAST PLUS. Especially when using standard size servos it is recommended to
use more than one power supply cable in parallel to preserve a stable voltage and to reduce power loss due to connection
resistance.The additional supply cables may be connected to free receiver ports. We recommend to use MICROBEAST PLUS HD
which oers a low resistant high-power input and which is well suited for larger model helicopters.
The assignment of functions to the radio channels is mentioned in the manual of your radio system. Also you may nd out the
function assignment by checking your transmitter‘s servo monitor. The connectors of MICROBEAST PLUS are assigned to the
functions as follows:
AIL|CH5 = Aileron, ELE|DI1 = Elevator, RUD (orange wire) = Rudder, PIT (red wire) = Thrust, Aux (brown wire) = Gyro gain
The wires for aileron and elevator additionally transfer the power between MICROBEAST PLUS and receiver.

3. MICROBEAST PLUS HD
Using the switch is optional.The device can also be operated without switch. Then it will be ON all the time. Anyhow, never connect
anything else than the switch to the switch port. Otherwise the device will get damaged!
Input voltage range: 3,5 – 8,4 Volts.
MICROBEAST PLUS HD in first line was designed for 550 size helis and larger which
use standard size servos with high current consumption. Here you can connect the
power supply directly to the additonal high-power input which reduces voltage loss
due to contact and wiring resistance significantly when high currents are flowing.
Always use the supplied power cable as connector between battery and MICROBEAST
PLUS HD. It is not recommended to directly plug in the battery at the device.
Continuous plugging and unplugging can cause the overlying servo plugs getting
unplugged accidentally or cause the adhesive gyro pad to get loose!
Receiver and servo plugs are connected to the ports on top of the unit, similar as
described for the standard (non-HD) MICROBEAST PLUS.
Switch
Receiver battery or BEC
High-power connector
When switched off MICROBEAST PLUS HD consumes a very low amount of standby current. Therefore always
completely disconnect the battery from the system if you do not use the model for a extended period of time to prevent
the supply battery from getting discharged and damaged in consequence.
MICROBEAST PLUS HD does not supply an internal voltage regulation! The voltage that is applied to the high
power connection port will directly be passed to the servo and receiver connections. Only use electronic components
(servos and receiver) that are designed for your power source.
Using the high power connection port is not a must. You can also use MICROBEAST PLUS HD in a conventional
manner by powering the unit from the receiver ports in the top row. However, using the electronic power switch system
is not possible then.
Switch plug
(Polarity not
relevant)
To initiate bind procedure on a single Spektrum® remote satellite connect the Spektrum bind plug to SYS port. When using
a DSMX remote satellite push and hold the button and turn on power while still holding the button down. The LED on the sa-
tellite will ash together with Menu LED Hon the MICROBEAST PLUS. When binding a DSM2 remote satellite do not touch the
button but only power on the device. The LED on the satellite will ash together with Menu LED N. Initiate the bind procedure
on the transmitter. Power o and remove the bind plug when nished successfully.
To bind the JR® RJ01 remote satellite initiate the bind procedure on the transmitter and power on the MICROBEAST PLUS.
The remote satellite will bind instantly. Connecting a bind plug or similar is not necessary.

4. PREPARING YOUR TRANSMITTER
With electric driven models remove the motor from the main gear when performing the basic setup for safety
reason! Additionally deactivate the throttle by using the „Throttle HOLD“ switch, so the motor won‘t start to turn when
moving the thrust stick.
When flying a nitro or gasser heli remove the servo horn from the throttle servo before first power up to prevent
jamming of the servo due to wrong servo setup.
You must not use any mixing functions on the output channels! Especially it is not allowed to use mixing functions for the
swashplate servos. Deactivate all output channels that are not used. In the basic configuration we only need pitch, aileron,
elevator, rudder, throttle and one channel to adjust the tail gyro gain.
Create a new helicopter model memory in your transmitter that supplies different flight modes for controling throttle, pitch
and the tail gyro gain in different flight situations.
Only the pitch channel
must be controled when
moving the thrust stick.
The same applies to aileron,
elevator and rudder.
Each control function must exactly control one output channel. The servo throws must be set to 100% and all trims and sub
trims must be zero. For the basic setup do not change the pitch curves yet. The throttle curves and throttle servo settings can
be adjusted as necessary for this model in case you do not intend to use the internal RPM Governor function of MICROBEAST
PLUS. If you want to use the integrated RPM Governor function also do not touch the throttle settings yet.

When using SRXL the preset channel assignment is based on the receiver‘s protocol version. MICROBEAST PLUS will detect automati-
cally which brand of receiver is used and will choose the appropriate channel assignment accordingly.
* Channel designation of Spektrum® transmitters: THR, AIL, ELE, RUD, GER, PIT, AX2, AX3, AX4
** only applicable with ProEdition rmware otherwise this channel by default controls CH6 Auxiliary output instead of channel 9
*** only for models with nitro or gas engine
When using a receiver with „Standard“ 5-wire layout the function assignment is simply determined by the order of physical
connection of the wires to the receiver outputs. Assignment by software is not provided and will not appear when choosing
this type of receiver. Here the AttitudeControl function (optional) will be controlled using the tail gyro gain channel. The RPM
Governor function can‘t be used in combination with this type of receiver. When choosing „Standard“ (Status LED off) at menu
point Aand briefly pushing the button receiver setup is finished!

Plug the rudder servo connector into CH4 output of MICROBEAST PLUS. Put the servo arm on the servo so that it forms roughly
an angle of 90 degrees with the rudder linkage rod and adjust the length of the linkage rod as described in the helicopter
manual.
When moving the rudder stick check if the servo is moved into the correct direction so that the helicopter will be moved
correctly in flight. If this is not the case use the servo reverse function of your transmitter and reverse the channel output that
controls the rudder function.
Push and hold the rudder stick into one direction to move the rudder servo and release the stick when the servo reaches the
maximum or mimimum allowed servo throw. Using the rudder stick you can reposition the servo at any time to adjust the
exact servo limit. If you do not touch the rudder stick for several seconds the current servo position will be saved as maximum
or minimum (the Status LED will flash and then light up solid in blue or red color). Then move the servo to the opposite
direction and wait until also this position gets stored (Status LED becomes purple).

Setup menu point F- Tail gyro direction
Lift the helicopter at the rotorhead and turn it on the vertical axis by hand. Observe in which direction the rudder servo moves
the tail rotor when turning the heli. The tail rotor must produce thrust against the direction of movement so that the rotation
will be stopped by the gyro in flight. For example if you move the helicopter‘s nose to the left the gyro must steer to the right similar as
you would move the rudder stick to the right manually.
