SAFETY NOTES
Radio controlled (R/C) helicopters are not 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.
The MICROBEAST-System is not a ying aid for beginners! It replaces the conventional mechanical ybar on most R/C helicopters. It is absolutely necessary that you have ying experience and that you are experienced in the operation of R/C helicopters. Otherwise 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.
Please read the following instructions thoroughly before the rst use of your MICROBEAST 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.
7
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.
Do not expose the MICROBEAST-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.
MICROBEAST consists of highly sensitive electrical components with limited capability to operate with excessive vibrations or electrostatic discharges. If you nd such disturbances in your model, the use of MICROBEAST should be postponed until the problems have been xed.
When operating the helicopter with a MICROBEAST 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.
Particularly when operating electric helicopters with single-line receivers, make sure that the elec­tric motor cannot start inadvertently during the setup procedure, if the ESC is connected directly to the MICROBE AST. 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.

Please note that these instructions are
only valid for the MICROBEAST rmware Version 3.x.x !
The delivered software version is printed on a sticker on the outside of the MICROBEAST packaging. You can also read it out on a computer by using the optional USB2SYS Interface and you can directly read on the MICROBEAST unit during the initialization phase, what rmware version your MICROBEAST is running: The MICROBEAST rst carries out a brief LED test by lighting up all menu LEDs simultaneously, and cycling the Status-LED color. Then for about 3 seconds, the Status-LED lights red while the menu LEDs A - G display the rst digit of the rmware version, and the LEDs H - N the second digit of the rm­ware version. Only the rst digit of the rmware version is of importance!
If only LED B is lighting or if the display on initialization is not as described, but ONLY a running light of all menu LEDs A - N, then the MICROBEAST is running an older version. In this case we recommend updating to the latest rmware version. If you like to continue to use the older rmware version, you must also use the appropriate instructions and not this manual!
You will get more information about the version display in section 11 of this manual.
Firmware version 3.x.x
On the rst column LEDs A and B must light corresponding to digit 3. LEDs H - N are irrelevant for the purposes of this instruction manual.
GENERAL INFORMATION

1. INTRODUCTION
Dear customer, thank you for choosing the MICROBEAST!
MICROBEAST is an easy to use three axis gyro system which makes it possible to y R/C helicopters without a mechanical ybar. This brings a boost in power as well as longer ight times and makes it possible to adapt the agility and ying behavior of your helicopter to your individual preference.
The MICROBEAST has a built-in high end tail gyro based on the latest MEMS Technology which gives your helicopter‘s tail perfect stopping behavior and constant rotation rate during any manoeuvers.
The MICROBEAST can be used in nearly any size of helicopter, using either electric motors or nitro en­gines for propulsion. It provides ight stability for beginners and maximum agility and precision for intermediate and professional pilots.
Nevertheless, the MICROBEAST is not a ying aid for beginners! If you are inexperienced with model helicopters, please consult an experienced pilot for help with setup and your rst ights.
The following manual will lead you step by step through the setup procedure from the correct moun­ting of the unit up to the rst ight. Please read the following instruction manual thoroughly. You will see that during the development of the MICROBEAST, that our focus is to user friendly and soon you will be able to operate the system intuitively.
The included overview map of the setup menu can be taken out to the ying eld as a quick reference to the various menu options.
Check our website WWW.BEASTX.COM where we will inform you about the latest updates and down- loads.
Now have fun and a good time using MICROBEAST!
Sincerely, the BEASTX-Team

3. MOUNTING AND CONNECTION
3.1 Mounting the MICROBEAST unit
Attach the MICROBEAST unit by using one of the provided gyropads at a preferably low vibrating position on your helicopter such as the gyro platform or receiver platform. You may also need to choose another type of mounting pad depending on the vibration pattern of your helicopter. Ask you MICROBEAST dealer.
The MICROBEAST unit can be attached at or upright, and even upside down under the helicopter. However, the servo connector pins must always point
toward the front (or rear) of the helicopter.
Pay attention that the edges of the MICROBEAST unit are all parallel with the corresponding axes of the helicopter! And be sure that the mounting platform is perpendicular to
the main shaft!

3.2 Preparing a transmitter for ybarless
(This step is unnecessary when using the MICROBEAST with the optional cable for stand-alone tail gyro use. Please see 4.1.2)
First create a new model in your radio‘s model memory. When using the MICROBEAST you have to disable any mixing functions for the swashplate or tail. Each function should be assigned to just one receiver chan­nel. As you see our requirement for the transmitter is very low.
Be sure that all trims and sub trims are disabled and that all servo travel are 100% (increasing or decreasing the servo travel for aileron, elevator and rudder can later adjust the maximum control rates, see chapter 9-B ).
Never enable your radio‘s eCCPM mixing function: this will be done by the MICROBEAST. Always set your radio‘s swash mixer to mCCPM (mechanical mixing) which is often called “H1” or “1 servo” mixing.
Do not adjust the pitch curve at the moment. For the setup procedures, it has to be set as a straight line from
-100% to +100% (or 0 to 100% depending on radio brand).
Again make sure that there are no mixing functions active (for example revo-mixing).
Other functions such as throttle curves, ESC switches or auxiliary functions can be adjusted as usual.
13
3.3 Servo connections and auxiliary channels
In slot CH1 is the elevator servo. With electronic swashplate mixing the two roll servos have to be con­nected to CH2 and CH3, with a mechanical mixed head (H1) the roll servo connects to CH2 and pitch servo to CH3. The tail servo is always connected on CH4.
Don’t plug the servos into the MICROBEAST yet! The correct servo type and appropriate driving frequency has not yet been selected in the Setup menu. We recommend not installing the servo
horns yet as the servos could bind and get damaged on rst power up.
When you route the wire leads in your model make sure that there is no tension passed to the MICROBEAST. Make sure that the MICROBEAST is able to move freely, so no vibrations get passed onto the unit. It is not recommended to bundle or tie down the leads close to the MICROBEAST. On the other hand the wires must be attached so that they are unable to move the MICROBEAST during the flight. In particular, do not use any shrink tubing or fabric hose to bundle or encase the wiring in close proximity to the point at which the cables are plugged into the Microbeast. This makes the cable stiff and inflexible and can cause even the slightest vibrations are trans­mitted to Microbeast.
At this point we would like to point out that the correct dimensioning of receiver power supply is very important (BEC and battery current rating, number of supply cables, cable diameter, cable length ...). For ybarless helicopters, the load on the servos and the resulting power consumption is signicant­ly higher than for helicopters with a ybar! Also the servos are constantly in motion when used with an electrical control system.

4. RECEIvER CONNECTION
In relation to the control of MICROBEAST you have the opportunity to use dierent types of receivers. It is distinguished between conventional standard receivers and socalled single-line receivers:
A standard receiver is a receiver that is connected to the MICROBEAST by using any single servo output of the receiver to connect the ve control channels between MICROBEAST and receiver. The channel which determines the controlled function simply is selected by inserting each plug to the correct output at the receiver. In section 4.1.1 it is shown how to exactly connect the receiver to the MICROBEAST when using the MICROBEAST as ybarless system. In addition the use of MICROBEAST is possible as a stand-alone tail gyro. See section 4.1.2 to learn how to connect receiver and MICROBEAST in this case.
When using a single-line receiver all channels are transmitted by one single connection line to the MICROBEAST. Because of this, it is not possible here by inserting the appropriate plugs in the receiver to assign functions to the MICROBEAST. This must be done by a specic setting in the MICROBEAST (described in chapter 5). Also single-line receivers similar to standard receivers with additional single channel connectors are available. Therefore you only have to treat such receivers as single-line receivers in combination with MICROBEAST if you really use this function.
How dierent types of single-line receivers are connected to the MICROBEAST is described in section 4.2.
Use as a stand-alone tail rotor gyro in single-line mode is possible under certain circumstances, but not intended and therefore is not described further in the following.
15
4.1 Connection of a standard receiver
4.1.1 Flybarless usage
Now plug the receiver cables for aileron, elevator, pitch, rudder and tail gain between the MICROBEAST and the receiver. To nd out the channel assignments of your remote control receiver, please refer to the user manual of your transmitter or contact its manufacturer.
To connect elevator and aileron, use the plain 3-wire cables that transmit the control signal in addition to the power supply from the receiver to the MICROBEAST.
Pitch (red), tail (orange) and gain (brown) have only one lead for the control signal on the receiver side, and are connected to the MICROBEAST on the combined connector. Please ensure these plugs are connected correctly to the receiver. Although the cable color is dierent, all three wires are signal lines, which go to the usual orange, yellow or white side! + and - remain open on theses channels.
Please respect the polarities for the plugs going to the MICROBEAST. The orange line on the MICROBEAST must always be on the top and the brown on the bottom. Also be sure when inserting the connectors
not to accidentally plug them into the space next to the pins or vertically oset by one pin.
Other wires such as throttle servo, ESC or power supplies are connected as usual to the remote control receiver.

The illustrations are only examples. Of course, the MICROBEAST also works with other receivers and remote control systems.
Remember that it is not the receiver that is crucial for the channel order but that this depends primarily on the allocation of control functions in the transmitter. If you do not know in which order the channels of your transmitter / receiver have to be connected, refer to the instructions that came with your transmitter and receiver, see the servo monitor of the transmitter (if available) or contact the manufacturer of your remote control system.

4.1.2 Usage as stand-alone tail gyro
The MICROBEAST can also be used as high-end stand-alone tail gyro. This requires the use of a special patch cable which can be purchased separately. This ensures that the MICROBEAST is provided with power and that the signals for rudder and tail gain are available from the receiver.
The signal lead with the orange and yellow wires must be connected to the slot [ Aux | Pit | Rud ]. The orange wire must be closest to the topside of the MICROBEAST.
The power lead must be plugged into the slot [ ELE | DI1 ]. The brown wire (negative or ground) is on the bottom, the red wire (positive or power) should be in the middle position. Connect the tail servo to [ CH4 ].
If using the MICROBEAST as stand-alone tail gyro only the menu points A, C, D, E and F need be adjusted in setup menu. All other menu points can be skipped.
To avoid damage to the tail servo, rst setup menu points C and D which are tail servo pulse and frequency, prior to connecting the servo.

4.2 Use of single-line receivers
The MICROBEAST enables the use of conventional receivers with individual channel outputs or the use of special receivers which output the channel signals as a merged single-line signal. These include Spek trum® satellite receivers, PPM composite signal receiver (e.g. Futaba® SP Series receiver or the satellite receiver from Jeti ®), receivers with Futaba® S-BUS as well as receivers with SRXL compatible data output (e.g. SRXL­Multiplex or BEASTRX).
4.2.1 General notes
When operating with single-line receivers (Spektrum® satellite receiver, PPM composite signal receiver
- e.g. Futaba® SP-series or the satellite receiver from Jeti®, receivers using Futaba® S-BUS, SRXL compatible receivers), the throttle servo/motor controller can be connected to [CH5] on the MICROBEAST. When using a motor controller for electric models with a BEC this slot then also will be supplying the MICROBEAST, the servos and the receiver with power.
We recommend if possible (e.g. on all receivers that have normal servo connectors together with single line output) to connect the throttle servo/motor controller directly to the receiver to benet from the native Failsafe/Hold functions. Although the MICROBEAST also has adjustable Failsafe for [CH5] this will only be activated when the connection between MICROBEAST unit and receiver fails but not for example in case of signal loss between transmitter and receiver.
On slot [DI2 | CH7 | CH6] another auxiliary channel is available on the top pin [CH6], for example to hook up a governor for nitro engines. Please note that this slot is only issuing a control signal and has no power. For this reason a servo cannot be plugged here directly. The two lower pins [DI2] and [CH7] are reserved for other applications. Never connect a power source on those two pins: this could
damage the MICROBEAST!
In the case of an electric model if the ESC has a second BEC output or when using a buering battery this wire can be connected to the [SYS] terminal or (if possible) plugged directly into the receiver.
On models with a separate power supply this can only be connected to the MICROBEAST on slot [SYS]. Therefore please ensure adequate sizing of the supply lines, especially with large models. A second power connection can be derived to the receiver or, by using a Y cable, you can inject a parallel power supply to one of the servo outputs. When using very powerful servos you might even consider using a separate voltage regulating unit that the servos can be connected to.
19
4.2.2 Spektrum® Satellite receiver
To connect a Spektrum® satellite (remote) receiver on the MICROBEAST a special optional adapter is required. This adapter is connected to the [DI1] input of the MICROBEAST. Please observe correct polarity, the orange signal line must be next to the cover. The cable for the Spektrum® satellite receiver is then plugged into this adapter.

Satellite receiver
The use of MICROBEAST with a single Spektrum® satellite receiver is allowed only on micro or mini helicopters (450 size helicopters) because of the limited range due to the lack of antenna diversity!
20
Binding procedure
In the case of using a Spektrum® satellite receiver it is very important to bind the receiver first before programming the MICROBEAST. This step is essential to perform, even if the satellite was already in use elsewhere (e. g. in connection with a “standard” Spektrum® receiver) and was already bound to the transmitter earlier.
To bind a satellite receiver, it must be connected via the adapter to the MICROBEAST.
Simultaneously with the binding process, the type of satellite receiver has to be set, i.e. whether it is a DSMX or DSM2 satellite (The actual selected signal protocol in the transmitter is not relevant!). It is very important to choose the correct type of satellite receiver here, since an improper setting may seem to work but can lead to radio interference or total loss of the link in the subsequent operation!
Insert a Spektrum® “Bind Plug” in the [SYS] slot on MICROBEAST. In cases where power is supplied exclusively by the [SYS] Connection, to bind a Spektrum® satellite re­ceiver, the power supply must be provided temporarily through any of the servo port (CH1 - CH5).
To select a DSM2 satellite and to enter bind mode, simply switch on the power supply now. The LED on the receiver and LED N on the MICROBEAST will start to ash. You can bind the transmitter as usual (for more information refer to the instructions of your radio control system).
To select and bind a DSMX satellite, hold down the button on the MICROBEAST while switching on the power supply. Now the receiver‘s LED and LED H (!) on the MICROBEAST will ash and you can release the button and bind the receiver with your transmitter.
After successful binding procedure the receiver‘s LED will stay solid. LED H respectively N ash alternately to all other LEDs. Now switch o the power supply and remove the bind plug. Now continue with receiver type setup (see next chapter).
Note: It makes no difference if you pull off the “Bind Plug” during the binding process or leave it connected as you would expect from some “standard” Spektrum® receivers.
Watch out that the motor can not start accidentally when using the BEC of your speed controller to power the unit!
21
Decisive for the selection alone is, which type of satellite receiver is plugged in! It is irrelevant which transmission method between the receiver and transmitter is actually used.
Check carefully what type you use. Crucial is the rmware on the satellite not its look! An incorrect setting is not obvious, but later will lead to malfunction or failure of the connection.

4.2.3 Connecting single line receivers without additional servo outputs (e.g. PPM composite signal receivers)
For the connection of PPM composite signal receivers there is usually no special adapter required. In most cases (e.g. Futaba ®-receivers of the SP-series) the receiver can be connected to the MICROBEAST with one of the supplied regular 3-wire cables. For some receivers, the connecting cable is also already xed to the receiver (e.g. Jeti ® satellite receiver).
If not xed to the receiver, plug the cable into the output of the digital composite signal of your receiver, usually labeled with “SIG” or the like. Again pay attention to correct polarity. Be careful, since the sup­plied cable is designed to be used “universally”, and the usual Futaba® polarity protection tab is mis­sing.
Plug the other end of the cable into the MICROBEAST input [DI1]. Make sure the polarity is correct; the orange signal line must be next to the MICROBEAST top cover.

4.2.4 Connection of single line receiver with additinal servos connectors (e.g. S-Bus, SRXL)
Connect the receiver to the MICROBEAST with one of the supplied regular 3-wire cables. Plug the cable into the MICROBEAST input [DI1] and the other to the receiver to the output [S. BUS] or [B | D] ® for Multiplex.
Please make sure that the connectors are plugged in with the correct polarity. Be careful, since the supplied cable is designed to be used universally, and the Futaba® polarity protection tab missing. On the MICROBEAST, the orange signal wire must be close to the top cover.
This description also applies to other single line receiver with additinal servos connectors (e.g. SRXL receivers (Multiplex or BEASTRX)):

5. RECEIvER TYpE SETUp
Beside using conventional receivers, the MICROBEAST supports the use of dierent types of sin gle-line receivers. These are receivers which transmit the control signals only over one single cable wiring. If using such a receiver because of the dierent signal protocols the receiver type must be selected in the receiver menu before the rst use and further steps such as allocation of individual channels or failsafe setting are needed. You can see from the yellow LED next to the letters A - N at which receiver menu point you are currently in. By briey pressing the button you can go to the next receiver menu point which also saves the current settings.
5.1 Receiver type choice (receiver menu point A)
To get into the receiver menu press the button on the MICROBEAST and hold it down while you turn on the receiver power supply. The yellow menu LED A should now be ashing and you can release the button.
If you use a motor controller with BEC, disconnect the motor for safety reasons to avoid the possibility of unintentional motor start up!
At menu point A where menu LED A is ashing, the color and state of the Status-LED gives you information about which type of receiver is currently selected (refer to the table below). In order to change the type of receiver, press and hold the button for about 2 seconds. The Status-LED will light in the next color or eventually ash. Repeat this as many times as required until the Status-LED matches your receiver type:
Status-LED Receiver type

purple Spektrum® Satellite (Fig. 7)
red ashing Futaba® S-BUS (Fig. 9,10)
red SRXL (Fig. 9,10)
blue ashing PPM - composite signal (Fig. 9,10)
*Factory Setting
Push and hold button for about 2 seconds
Note: By default the use of a conventional standard receiver is provided. Therefore it is not necessary to call the receiver setup menu. Skip the following sub-items and proceed with chapter 6.
25
Then press the button, but only briey, to save the setup and switch to receiver menu point B. If you have already briey pressed the button by mistake and it did not change the receiver type but switch to menu point B, switch o the power and repeat the above procedure.

Note: If selected receiver type is “Standard” the set up is now complete and by briey pushing the
button you will jump directly to the end of adjustment procedure (all menu LEDs are ashing). Switch o the power supply now. Another channel assignment is not necessary and not provided since the allocation takes place by appropriate insertion of the cables into the “standard” receiver. So you can directly proceed with chapter 6.
26
5.2 Input channel assignments (receiver menu points B - H)
If not a standard receiver but a single-line receiver was selected at menu point A, it must be established which control function is controlled by what channel. This is necessary because all the control functions are transmitted via one single line and thus there is no possibility of plugging the cables in each individual channel matching at the receiver.
5.2.1 Preset channel assignment
When selecting a specic type of single line receiver the appropriate type of receiver channel allocation will be preset in the MICROBEAST. Please refer to the tables below and check if your radio transmits the channels in the correct order. If this is not the case, you have to assign the channel order step by step through the menu points B - H (for this see section 5.2.2). To know the channel assignment of your
transmitter you can check the user manual of the transmitter or look at the servo monitor of the transmitter (if it has this feature). If in doubt ask the manufacturer of your transmitter.
When using SRXL the preset channel assignment is based on the receiver‘s protocol version (see next page).

Note: If the selected receiver type is “standard” another channel assignment is not necessary and not provided since the allocation takes place by appropriate insertion of the cables into the “Standard” receiver. Therefore menu points B to N are not accessible and the MICROBEAST jumps after the brief press at menu point A to the end of the receiver menu (all menu LEDs ashing). Power o the unit now and proceed as described in chapter 6.
If you are on receiver menu point B, please wait until the Status-LED lights blue.
If the Status-LED stays red, it means that there is no valid remote control signal available. A channel assignment in this case is impossible! If the Status-LED doesn’t turn blue after a few seconds, check if the receiver is properly bound to the transmitter (bind already done successfully?) and that a receiver of the correct type is selected in receiver menu point A. If a wrong receiver type has been selected, switch o the power and restart the receiver type setup procedure.
To load the selected standard channel assignment (see above tables), hold the button down for sever­al seconds. The menu LED will immediately jump to receiver menu point N. In addition, you can also load the default settings by pushing the button for several seconds in any of the points from C to H. This will erase all previously made individual channel assignments.

5.2.2 Teaching of customized channel order
If you need a customized channel order, please rst prepare (if not already done) your transmitter as described in section 3.2 .
Additionally, make sure (for example, using the servo monitor of your transmitter) that each control function of your transmitter activates one and only one channel. This can be tricky especially for
throttle/pitch functions which are usually coupled by a mixer in the transmitter. In this case set the throttle channel quiet by using for example the throttle hold switch or provide a at throttle curve so that the pitch stick actually controls only the channel for the pitch servo, but for the later, keep the possibility to control also the throttle channel by ipping a switch for example.
In the following 7 menu points B - H, you can assign dierent functions by simply actuating the appropriate channel function on your transmitter. A blue ash of the Status-LED indicates that a channel has been detected. It does not matter how far or in what direction you move the stick or in what position the stick/ switch was. Note the channel value itself is not important, but the change of this value is. It is therefore important that only the requested function is activated and not by accident several simultaneously. Otherwise, the MICROBEAST may not recognize the allocated channel correctly.

If you have moved the wrong stick/switch, you can reactivate the correct function again. The MICROBEAST remembers only the last function that was operated and conrms it with blue ashing of the Status-LED.
Press the button after learning each function to save the assignment and to go to the next function. The button remains locked until you operate a new control function. You have to assign every function with the exception of the last auxiliary channel CH6 (this channel can be skipped by pressing the button without learning the function).
Once a channel is assigned, it is no longer available and is ignored by the MICROBEAST for the remaining process. Thus, after learning of the pitch function (menu point B) you can enable the throttle
function (remove throttle hold and switch to a linear or V shape curve) and teach the throttle channel by re-operating the collective stick (menu point G). The pitch channel is now no longer considered, as this channel has already been assigned previously!

5.3 Programming the Failsafe (receiver menu point N)
At receiver menu point N you have to program the fail-safe position for the throttle channel. If during ope- ration, the received signal is interrupted, the throttle servo / motor controller (connected to the output CH5) is automatically reset to this fail safe position. To avoid accidents, you should program electric motors to “o“ and reduce throttle on nitro helicopters to idle.
We recommend to directly connect speed controller and additional functions to the receiver to use the Failsafe / Hold functions of the remote control system (see 4.2.1). But you can also CH5 and CH6 on the MICROBEAST for these functions!
Set the throttle channel on your remote control to the desired position and press the button briey. If you did not connect a function to CH5, anyway press the button to complete setup.
This completes the basic receiver setup and the MICROBEAST will go into sleep state after the button is pressed (all menu LEDs ash). Power o the unit and proceed as described in the next chapters.

6. SETUp pROCEDURE OvERvIEW
After powering on the MICROBEAST will initialize. During this phase, do not move the MICROBEAST unit or the helicopter. First the MICROBEAST runs a short LED test and then the rmware version is displayed for 3 seconds. After
that, the running LEDs A to G show the calibration of the sensors and the LEDs H to N the initialization of the receiver inputs.
When the system is ready it does a short move of the swashplate servos and the Status-LED turns blue if the tail gyro is in HeadingLock mode or purple in Normal-Rate mode. For about 10 seconds you can see one of the LEDs A - N light according to the current amount of tail gain.
The programming of the MICROBEAST works in the following way:
There are two menu levels. From ready mode (ight mode) you can always get into the one or the other menu level. A change between the menu levels is not possible; you always have to rst get out of the current level to enter in the other menu level. Each level includes several setup points. The yellow LEDs next to the letters shows at which setup point you are currently. Note that the two menu levels have a dierent number of setup points.

skip a menu point. Therefore do not move any stick while being in the menu point you want to skip, and just press the button once again.
After the last menu point, a short press on the button will exit the menu. Then the MICROBEAST is ready to y again. If there is no stick or button input for 4 minutes while being in one of the menus, the MICROBEAST will exit the menus automatically. (This is not true in the setup points D, G, I and J to give you enough time to adjust the mechanical setup of your helicopter).

7. SETUp MENU
Before the rst ight the MICROBEAST has to be adjusted to your helicopter and the used components.
When the MICROBEAST shows that the system is ready, press and hold the button down, the menu LED next to menu point A will begin to ash and then after a while will be steady on. Now and only now you can release the button. You just entered the setup menu in menu point A.
To leave the setup menu you have to skip through all menu points by pressing the button several times. After pushing the button at menu point N you will exit the setup menu and the system is ready for operation again. None of the LEDs A - N are glowing anymore (see chapter 6).
If there is no stick or button input for 4 minutes, while being in the setup menu, the MICROBEAST
will exit the menu automatically. (This will not happen during setup points D, G, I and J to give you enough time to adjust the mechanical setup of your helicopter).
Factory Reset:
To reset the MICROBEAST to factory settings, you can, at any setup menu point, push down the button for at least 10 seconds until the LEDs A - N and J quickly blink one after the other to conrm the reset.
Please note that any previous conguration is now deleted. Do not attempt to y the helicopter without doing the complete setup procedure again otherwise you will crash your helicopter. Please also note that all
servo settings are lost, therefore you should unplug the servos and remove the servo horns before resetting the MICROBEAST.
The receiver type settings (see chapter 5) are not aected by the reset!
Conversely, if you change any settings in receiver type, the setup menu or parameter menu are not aected. However, you have to redo the receiver-specic settings (channel assignment and fail-safe, see sections 5.2 to
5.3).
37
A Mounting orientation of the MICROBEAST
The MICROBEAST unit can be mounted in nearly all possible orientations. The only restriction is that the plug connectors have to point in or against ying direction (see chapter 3).
At setup menu point A, you have to choose whether the MICROBEAST is mounted horizontally (prin­ted surface 90 degrees to the main shaft) or vertically (printed surface in parallel with the main shaft).
The color of the Status-LED shows the currently selected orientation:

If you do not know what the maximum pulse rate tolerated by your servos is, please select not more than 50Hz driving frequency. A higher driving frequency can lead to failure of the servos!
Analog Servos usually tolerate only 50Hz, some types up to 65Hz. Digital servos allow usually higher fre­quencies, but this has to be veried in the servo datasheet. You may need to check with the manufacturer of the servos.
On WWW.BEASTX.COM you can nd a list of parameters for the most common servos.
To optimize the performance of the MICROBEAST, the rule is the higher the better! Nevertheless if you experience an unusually high power consumption of the receiver power supply or if the servos get hot, you should reduce this frequency.
With high frequencies, some servos run in a jerky manner, especially the fast ones like coreless or brushless servos. This is due to the high update rate that the servo receives. This is not critical and will not impact ight performance.
The color and state of the Status-LED shows the currently selected frequency:

If you are using the MICROBEAST as stand-alone tail gyro with the optional patch cable (see section 4.2.2) it is not necessary to make any adjustments at this setup menu point.
Setup menu point B is for selecting the servo frequency of your swashplate servos.
*
Factory Setting
39
The MICROBEAST can be used with nearly all available servo types. However, the selected servos should be adequate for ybarless operation (high torque and also fast and precise).
The quality of the servos will have a direct inuence on the range of rotor blades that can be used. The more the servos are suited for ybarless operation, the less important is the ybarless specicity of the rotor blades.
The use of a bad servo-rotor blade combination will lead to several issues, ranging from oscillations du­ring hover to unwanted reactions in fast forward ight.
To select the desired servo frequency, move the tail stick repeatedly in one direction until the Status-LED lights in the correct color.
The option “user dened” allows you to dene your own setting with the PC software.
Push the button to save the conguration and to proceed to setup menu point C.
40
There is a relationship between the setting of the tail servo center position pulse length and the tail servo frequency (menu point D). If a pulse length is selected that does not allow a certain frequency, this fre­quency is automatically reduced. The center position pulse-setting always has priority, since a servo can run without problems at a too low frequency but can not be operated with an incorrect center position pulse.
On WWW.BEASTX.COM you can nd a list of parameters for the most common servos.
The color of the Status-LED shows the currently selected servo center position pulse length:
C Tail servo center position pulse length
At setup menu point C you can select the pulse length for the tail servo‘s center position. Almost all commercially available servos work with 1520 μs. But there are a few special tail servos on the market which use a dierent center position pulse length.
To select the desired servo center position pulse repeatedly move the tail stick in one direction until the Status-LED glows in the correct color.
The option “user dened” allows you to dene your own setting with the PC software.
Push the button to save the conguration and to proceed to setup menu point D.

Please note that depending on the tail servo center position pulse length chosen at setup menu point C, you may not be able to choose a frequency higher than 333Hz. This also applies to the “user dened“ setting which might be limited to 333Hz (see also note at setup menu point C).
If you do not know what the maximum frequency tolerated by your servo is, please select not more then 50Hz. A higher frequency can lead to failure of the servos!
Analog Servos usually tolerate only 50Hz. Digital servos usually allow higher frequencies, but this has to be veried in the datasheet of the servo. You may need to check with the manufacturer of the servos.
On WWW.BEASTX.COM you can nd a list of parameters for the most common servos.
D Tail servo frequency
As with the swashplate servos at setup menu point B you can select at setup menu point D the frequency for the tail servo.
To optimize the performance of the MICROBEAST tail gyro, the rule is the higher the better! A good rudder servo should be capable of running at least 270Hz.
By moving the tail stick repeatedly in one direction you can choose the desired tail servo frequency.

Next attach a servo horn to the tail servo in such a way that the tail linkage rod forms a 90 degree angle to the servo horn (or as close as possible) and then adjust the linkage rod as described in the manual for your helicopter. For most helicopters the tail pitch slider should be centred and the tail rotor blades will then have some positive pitch to compensate for the torque of the main rotor.
Note: This menu item will not be left automatically after 4 minutes, so you have plenty of time to adjust the mechanical setup.
Push the button to save the conguration and to proceed to setup menu point E.
43
Pay attention that the steered direction of your tail stick corresponds to the direction your helicopter should turn. If this is not the case, use your transmitter‘s servo reversing function for the tail stick. If you‘re not sure in which direction the helicopter should rotate consult the manual for your helicopter.
E Setting the Tail rotor endpoint
At setup menu point E you adjust the best possible servo throw for your tail rotor. This best throw is determined by the maximum possible control travel of the tail mechanism or based on the maximum allowed angle of attack of the tail rotor blades, that will not lead to an aerodynamic stall of these bla­des. Such stalls can cause very bad stopping behavior.
To adjust the limits, move the tail stick in one direction until the servo reaches the maximum end point without any binding or stall and release the tail stick. The further you move the tail stick the quicker the servo will steer into the given direction. If you move the servo too far you can steer the stick to the opposite direction and move the pitch slider a short way back.
Once you adjusted the maximum endpoint don‘t move the tail stick anymore and wait for the Status­LED to ash and then light steady red or blue, depending on the adjusted direction. Now you have saved the servo limit for one direction.
Fig. 22
Red or blue
44
Then adjust the servo limit for the other direction. Drive the tail pitch slider by using the tail stick to the other maximum endpoint and then release the tail stick. After a short moment, the color of the Status-LED should start ashing followed by lightning steady purple, (mix of red and blue) indicating that the servo endpoint adjustment is complete.
Fig. 23
Status-LED: red or blue
Status-LED: purple
If the Status-LED does not light or lights in an unexpected color, the servo throw is obviously
too small. In this case mount the linkage ball of the tail linkage rod further inward on the servo horn.
This ensures that the tail gyro of the MICROBEAST will perform in the best way and that enough servo resolution is available.
Push the button to save the conguration and to proceed to setup menu point F.
45
If this is not the case you have to reverse the sensor direction. This happens by moving the tail stick once into any direction. For conrmation you will see that the Status-LED will change its color.
At setup point F, you can nd this out very easily:
The gyro always tries to steer in the opposite direction of the rotation that is applied to the helicopter.
If you move the helicopter by hand around its vertical axis, the gyro must actuate a tail servo movement to compensate this rotation. If for example you move the nose of the helicopter to the right, the gyro has to steer left the same way as you would steer left with the rudder stick (see g. 24)
F Setting the Tail sensor direction
Here you have to check if the MICROBEAST‘s tail gyro does compensate into the right direction.

Note: This menu item will not be left automatically after 4 minutes, so you have plenty of time to adjust the mechanical setup.
You can switch back and forth between the servos as often as you need, and also switch back to the zero position for reference anytime. The already adjusted servo centers will not be lost doing this.
Note that only the adjusted servo positions are important and get stored. Those which have been set with the corresponding Status-LED colors. The Status-LED “o” only serves for reference and to plug the servo horns in the best position. For instance, if you install or replace the servos in the model.
G Adjusting the swashplate servo centering
When entering setup menu point G connect all swashplate servos as described in chapter 3.3. They now will be running to their zero position (1520 µs) what we call reference position here when the Status-LED is o.
This reference position is used to mount the servo horns on the servos so that they form as much as possible a 90 degrees angle to the linkage rod. Usually this will not work out perfectly depending on the servo‘s gear train and the servo horn, therefore you can adjust electronically every single servo in the next steps. Later, you can come back anytime to this reference position (when the Status-LED is o ) for checking the mechanical setup..
If you move the tail stick to a single direction once, you can select one servo and change its center position by moving the elevator stick back and forth. Every color of the Status-LED is corresponding to a specic servo channel that is indicating its selection by a short up and down move.
Status-LED Function

If you move the tail stick once again in the same direction as before you can select the next swash servo and adjust its center position as mentioned.
48
Now adjust the linkage rods according to your helicopter manual. The swashplate should now be at the midpoint and perpendicular to the main shaft and the rotor blades should have 0 degrees of pitch. Always work this out from bottom (servos) to top (blade grips).
Also level and phase the swashplate driver in the correct way.
At 0 degrees of pitch the swash driver arms must be horizontal and the linkage balls of the blade grips have to be perpendicular to the spindle shaft.
Push the button to save the conguration and to proceed to setup menu point H.

H Swashplate mixer
At setup menu point H you can choose the electronic swashplate mixer your helicopter requires or choose “mechanical“ for switching of the electronic swashplate mixer if your helicopter has a mechanical mixer. For the electronic mixer, the MICROBEAST supports 90°, 120° and 140° swashplates. Besides these choices, you can set any swashplate geometry with the PC software and “mechanical“ for switching o the “electronic swashplate mixer” option.
Which kind of CCPM your helicopter uses can be read in the manual for your helicopter.

I Setting the swashplate servo directions
At setup menu point I, you adjust the correct swashplate servo directions. To facilitate this setup, you don’t need to adjust every servo by its own, but just try the 4 possible combinations.
Move the pitch stick and check if the swashplate moves horizontally up and down. The direction itself is not yet important. If one or more servos are not running in the right direction, just choose another combination by giving a short rudder input. Repeat this rudder input until all servos are running in the same direction.
Check now, if your control directions of aileron, elevator and pitch are correct. If this is not the case, you have to use the servo reverse feature of your transmitter to reverse the appropriate control function...
Push the button to save the conguration and to proceed to setup menu point J.
Note: This menu item will not be left automatically after 4 minutes, so you have plenty of time to adjust
the mechanical setup.
If the servos are still not reacting properly to aileron and elevator functions, check if the servos and receiver wires are connected as described above in section 3.3 and chapter 4. Also check if the channel assignment within receiver menu has been done correctly (section 5.2) if applicable. Additionally verify the settings of your transmitter on any remaining mixer functions (see section 3.2).

J Teaching the cyclic pitch geometry
At this setup point J, you have to tell the MICROBEAST the available cyclic pitch range.
First don‘t touch any stick on your transmitter when entering setup menu point J. Orientate one of the rotor blades so that it is parallel to the tail boom (Fig. 28). Then attach a pitch gauge to this rotor blade. The swashplate should be in the neutral position and the blades should have 0 degrees of pitch, otherwise repeat the swashplate servo centering at setup menu point G.
Now move the aileron stick until the rotor blade has an exact 6 degrees of cyclic pitch and then release the stick ( Fig. 29). If you moved the swashplate too far you can steer the stick to the opposite direction and reduce the pitch. Also by moving the tail stick to one direction you can delete the adjustment and reset the swashplate back to 0 degrees.
The direction you choose is not important, what is important is that you keep the position steady on 6° when you save and leave this menu step. It is not enough to go to 6° and then move back before saving and leaving.
When reaching 6 degrees, the Status-LED should light blue. This indicates that your helicopter‘s rotor head geometry is perfect for the use with a ybarless system. Otherwise, if the Status-LED‘s color is red or purple or even if the Status-LED is o, this indicates that your helicopter‘s geometry is not optimal for ybarless usage. Correct this by using shorter servo horns, shorter linkage balls on the inner swashplatering or longer blade grip link levers.
Push the button to save the conguration and to proceed to setup menu point K.
Note: This menu item will not be left automatically after 4 minutes, so you have plenty of time to adjust
the mechanical setup.
Always set the cyclic pitch to 6 degrees! This setup does not aect the maximum rotation rate of the helicopter but is only there to show the MICROBEAST the actual mechanical cyclic geometry. A wrong adjustment at this step may be extremely detrimental to the performance of the MICROBEAST. The blue color of the Status-LED is secondary and just for information.

K Adjusting the collective pitch range
At setup point K you adjust the maximum desired negative and positive collective pitch.
Move the pitch stick all the way up and stay there. Now you can increase or decrease the maximum amount of pitch using the tail stick.
When you adjusted the desired maximum pitch angle, move the pitch stick all the way down and again in­crease or decrease the pitch to the minimum desired value using the tail stick.
Don‘t use any pitch curves in your transmitter while doing these adjustments. Later on for the ights, you can adjust your pitch curves as you like and are used to. Setup menu point K solely serves to teach the MICROBEAST the maximum used pitch range.
Push the button to save the conguration and to proceed to setup menu point L.
At this point, verify again that the demanded pitch direction on the transmitter is in the correct direction for the model. Otherwise use your transmitter‘s servo reversing function for the pitch channel to correct this as already described in section I.

L Adjusting the cyclic swashplate limit
At setup menu point L you adjust the maximum possible tilting of the swashplate for aileron and elevator. The deection will be limited in a circular path similar to a cyclic ring function.
For adjustment proceed in the following way: Carefully move the sticks for aileron, elevator and pitch to all maximum end points and watch out if the swashpla­te, the linkage rods or servos are binding somewhere or even getting not more driven.
By moving the rudder stick to the left or right, you can increase or decrease the aileron and elevator throw limiter. Always try to achieve the maximum possible cyclic throw. The higher the swashplate deection is set the greater it will be in ight. This will achieve the maximum possible rotation rate of the helicopter without sacricing the gyro control loop.
If afterwards any modications are done to one of the other setup menu points which aect servo adjustments (setup menu points G, J and K) the cyclic swashplate adjustment has to be redone.
Push the button to save the conguration and to proceed to setup menu point M.
Similar to setup point J, the color of the Status-LED indicates whether the adjusted limit allows sucient cyclic throw. In the ideal case, the swashplate is limited only to the extent where the Status­LED still lights blue. In particular, for models that are intended to be used in 3D aerobatics, 10° to 12° cyclic throw should be possible. But even for all the other helicopters, it is recommended to adjust as much throw as possible, because otherwise the control loop may not work properly. Here, the color of the Status-LED provides a clue. If you get only purple or even no light at all, it is essential that you change the mechanical setting of your model to increase the available throw.
55
M Setting the swashplate sensor directions
At setup menu point M, you check if the sensors for aileron and elevator are working in the correct direction.
This can be directly veried in this menu point: If you roll or tilt the helicopter by hand the swashplate has to steer against this movement. Please refer to this on the next pages Fig. 30 and 31.
If this is not correct, you can reverse the sensor directions by moving the tail stick in one direction. For conrmation you will see that the Status-LED changes color. Repeat this step until both sensors are correcting in the correct direction.
There are four possible displays for control to choose from, one will be correct:
Push the button to save the conguration and to proceed to setup menu point N.
When tilting the helicopter forward the swashplate has to move backwards, when tilting the heli­copter to the back, the swashplate has to compensate forward. Same thing applies to the roll axis, when you roll the helicopter to the left the swashplate has to steer right and vice versa. Basically the swashplate has to remain horizontal while banking the helicopter.

N Setting the pirouette optimization direction
When entering setup menu point N the swashplate will tilt forwards or backwards depending on your helicopter‘s setup (servos, linkages,…) this resulting tilt will correspond into a specific com­pass heading.
Now grab your helicopter at the rotor head and rotate it on the vertical (yaw) axis by hand. The swash­plate must continue to maintain the same compass heading (see g. 32 on the next page). The initial direction (forward or backward) is irrelevant.
If the noted swashplate tilt opposes the rotation of the helicopter and rotates against the direction of the model the pirouette optimization should be invert. This can be done by moving the tail stick in one direction. For conrmation the color of the Status-LED on the MICROBEAST will change:

8. DIALS AND TAIL GYRO GAIN
To adjust the dials please only use the original plastic BEASTX adjustment tool to prevent damage to the dials!
8.1 Swashplate: cyclic gain (Dial 1)
Turn dial 1 clockwise to increase the swashplate gain.
The factory setting for the dial is horizontal which corresponds to 100% swashplate gain. For your rst ights we suggest not changing this setting. However, when using very small helicopters (such as 250 or 450 size), reduce the swashplate gain slightly.
In general the higher the gain the harder the helicopter will stop after cyclic moves and the helicopter will feel more stable in the air. If the gain is too high the helicopter feels spongy and tends to oscillate especially on the elevator axis.
If the gain is too low the helicopter does not stop precisely after a cyclic movement and feels unstable in fast forward ight.

61
8.2 Swashplate: direct cyclic feed forward (Dial 2)
Turn dial 2 clockwise to increase the swashplate’s direct cyclic stick feed forward. This is the part of the stick input that is going directly to the servos. If correctly adjusted, this relieves the control loop which will work more eciently by only having to make residual corrections. Factory setting of the dial is horizontal which provides a good setup in most cases.
Increasing the direct cyclic feed forward will cause more cyclic stick input going directly to aileron and elevator on the swashplate. Decreasing the direct stick feed forward will do the opposite.
If the direct cyclic feed forward is too high, it will over control your cyclic input. The control loop needs then eventually to steer back. Even though you get the impression to have a more direct control, unwanted side eects may appear, like pitch backs on cyclic stops and imprecise fast forward ight.
If the direct cyclic feed forward is too low, the helicopter will feel softer, slower and less direct. The optimal point depends of many factors like blades, servos, head speed, size and mass of the helicopter.
At delivery the dial is in the middle which should be a good starting point for most helicopters.
8.3 Tail dynamic (Dial 3)
Turn dial 3 clockwise to increase the tail dynamic. Turning dial 3 counter clockwise will decrease the tail dynamic. Factory setting of the dial 3 is horizontal which provides a good setup in most cases.You have to make sure the maximum possible tail gyro gain has already been determined (see section 8.4) befo­re adjusting the tail dynamic.
Increasing the tail dynamic will lead to harder stopping behavior and more aggressive response to tail stick inputs. If the dynamic is too high the tail will bounce back shortly after a hard stop and feel spongy when making fast direction changes. If the dynamic is set too low the tail feels dull and stopping might be too soft. Ideally the tail should stop perfectly to the point without making any apping noises.
The direct cyclic feed forward does not aect the maximum rate of rotation! If the helicopter turns too slowly, you should check the settings of the swashplate limiter in setup menu L, change the control behavior in the parameter menu at point B, or increase the servo travels or “Dual Rate“ setup in your remote control.
62
8.4 Tail gyro gain (adjusted by the transmitter)
As with a conventional tail gyro, the tail gain can be adjusted by one of the transmitter‘s auxiliary channels. In one direction you can select the Normal-Rate mode and in the other direction HeadingLock mode.
The color of the Status-LED indicates the selected mode when the MICROBEAST is ready for operation.
Purple indicates Normal-Rate mode and blue or exceptionally ashing blue indicates HeadingLock mode. Additionally while adjusting the gain or shortly after the rst start up, the current amount of gain is displayed by one of the menu LEDs for about 10 seconds. So you always know the actual amount of gain in your helicopter as percentages will depend of the used transmitter. When the gain channel is centered, this will correspond to 0% gain indicated by LED A. In both modes, the maximum adjustable tail gain is 100% and will correspond to LED N, but the actual percentage in the transmitter will depend on its brand and/or type.
For the rst ight we suggest to start with a gain not higher then F or G in HeadingLock mode. To nd the optimal gain, we recommend starting with a low gain, where the tail will feel very weak and will stop with overshoots. Then increase the gain step by step and you will feel the tail having more and more precise stops, and hold better and better on jerky pitch inputs. If the gain gets too high, the stops will bounce back quickly and wagging will appear in fast forward or backward ight.
Operation without using a sensitivity (gain) channel is not possible!

9. pARAMETER MENU
When the MICROBEAST is ready, hold down the button until the Menu LED next to point A ashes quickly and then release the button. This is how to enter the parameter menu.
To switch to the next parameter menu point, just briey press the button once again. After the last menu point pressing the button one time more exits the parameter menu and the MICROBEAST is ready for ight again. Status-LED will indicate the tail gyro mode and the LEDs A - N are o.
Single menu points can be skipped without performing any changes. Therefore don‘t move any stick while you are at the menu point you want to skip and just press the button shortly once again. The parameter menu has only eight points A to H, after point H you exit the parameter menu and the MICROBEAST returns to ight mode.
Never attempt to y when the MICROBEAST is in one of the menus! In this condition the control system and sometimes the stick inputs are deactivated!
64
A Swashplate cyclic center adjustment
The rst menu point in the parameters menu gives you the possibility to easily adjust your servo centers on the ying eld as for instance your helicopter is wobbling during pirouettes or when it doesn’t climb out straight on quick pitch inputs.
Never use the trim functions of your remote control! The MICROBEAST will see trim as a control command and not as servo trim.
Contrary to centering every single servo in the setup menu point G, here you are able to directly adjust aileron and elevator without taking care about the single servos. However, the collective pitch cannot be adjusted here.
Similar to the digital trim function of most transmitters here at parameter menu point A you can adjust the swashplate “one click“ by shortly moving the aileron or elevator stick in the desired direction. If you want to trim the swashplate any further repeat tapping the stick several times or simply hold the control stick pushed for a longer time to automatically perform several trim steps.
During the sub trim procedure you can delete the just performed trimming by moving the tail stick in any direction. Additionally the color of the Status-LED gives you an approximate indication of how much you did trim.
But remember that this function as opposed to the digital trim of the transmitter is not a separate trim function. Here you directly adjust the servo centers as well as you would set servo centers in the setup menu point G. If the new position is saved once then this corresponds well to the new servo center position in the setup menu point G. A subsequent reset to the previous state is not possible anymore!
Push the button to save the conguration and to proceed to parameter menu point B.
65
B Control behavior
At parameter menu point B you can choose between dierent control behaviors for your helicopter. This includes the maximum rotation rate of the helicopter as well as how sensitive the MICROBEAST will react to stick inputs for aileron, elevator and rudder around the stick centre.
Factory setting for this option is “sport“! This should be suitable for most pilots.
If you are a rather inexperienced model pilot it is absolutely suggested to select the option „normal” for the rst ights. In this state the rotation rate on cyclic and tail is very much decreased and the stick inputs around center are very gentle. Then nd your individual preference by increasing the option step by step.
The choice is done by moving the tail stick in one direction until the LED indicates the desired color and state.
If you are not satised with the presets, you may adjust the control behavior completely through your remote control. To do so, set the control behavior to “transmitter” (Status-LED “blue“).
The maximum rotation rate for aileron, elevator and rudder can then be adjusted by increasing or decreasing the servo travel for the corresponding function in your transmitter. Approx. 100% stick throw (servo throw in the transmiter) are equivalent to full rotation rate in this mode. In this mode,
there is no expo programmed in the MICROBEAST and you also have to set this in your transmitter.

When using the predened control behaviors we do not recommend to additionally adjust con­trol curves (Expo/Dual rates) in your transmitter as this will mix indenable the preset curves of the Microbeast with the curves of the transmitter. But if you only make little changes (e.g. slightly
increasing the servo throw to increase rotation rate) this should be no problem.
Additionally when using the setting “transmitter” by increasing the tail stick throw, in HeadingLock mode you get to an additional feature where the tail rotation rate is not limited by the gyro anymore. With this feature, extremely high tail rotation rates are possible. The state of the Status-LED shows if this high rate mode is reached. If the LED starts to ash at full tail stick input, you are on the controlled rotation rate limit. If you increase the tail stick servo travel further, the Status-LED will end up turning o when at full stick input. From this point on the rotation rate is no longer limited by the maximum gyro sensor capability, and you get into a free spinning area that can not be controlled by the gyro anymore. By further increasing the stick input (dual rates, or servo end points), the maximum rotation rate will increase even further, as far as the mechanics of the helicopter will allow it!
The option “user dened” allows you to dene your own setting with the PC software.
Push the button to save the conguration and to proceed to parameter menu point C.
This feature should only be used briey for special Show-maneuvers, for instance by temporarily switching the dual rate to higher stick throw. Note there is no tail gyro control in this unregulated range and it is very difficult to properly control the tail in this state!
Therefore, make sure that in normal ight operation the Status-LED at full rudder stick does not turn o. If it does, please reduce the servo throw or dual rate for the tail channel in your remote control.

C Swashplate – pitching up compensation
While in fast forward ight apply jerky collective pitch inputs to test this function. The helicopter should mainly remain in its horizontal path during climbing and descending. If the nose of the helicopter is pitching up and down heavily like a swimming dolphin, increase the value at parameter menu point C to compensate for this eect. But, if the value is too high the helicopter might feel sluggish and lazy. Try to nd the lowest suitable setting.
If the helicopter is still pitching up at the highest value, try alternatively to increase the swashplate gain (Dial 1) and use faster and stronger servos as well as rotor blades as neutral as possible (for example blades specically designed for ybarless helis).
The currently selected value is indicated by the Status-LED color and state:

D Tail HeadingLock gain
At parameter menu point D the HeadingLock gain for the tail can be adjusted:
The HeadingLock gain determines how constant the tail will maintain the rotation rate predetermined by the stick (this includes a rotation rate of height 0 = stick center position). Start with the HeadingLock gain set to low or very low and nd out the highest possible tail gain in your transmitter. Then you can start to increase the HeadingLock gain:

controlled clean. It is also possible that the tail will commute gently while hovering or ying around (which also often can be a sign of a sti tail mechanics!) and bounce back when stopping the rotation.
Was the appropriate setting determined it is usually necessary to adjust the tail gyro gain in the transmitter again.

If the tail pirouettes and stops unevenly in both directions, it is recommended to set the tail gyro to Normal-Rate mode in order to test, whether the tail will drift in a particular direction during hover. If it does, adjust the tail link rod length accordingly, so that the tail blades have the required compensation pitch. Do not forget, to redo the tail rotor limits (setup menu point E).
If you did choose in the parameter menu the control behavior “transmitter” please make sure that you are not accidently entering the free spinning range which might be a reason for inconsistent rotation rates. See note in parameter menu B (control behavior).

E Stick deadband
At parameter menu point E you can adjust the stick dead band for elevator, aileron and rudder. The deadband is the range around the very center of the stick where the MICROBEAST will not react. Unfor­tunately, some on the market available transmitters have the problem that when the sticks are brought back, after an input, to the middle position, they aren’t exactly at the same center position as before. This generates a continuous deviation on the corresponding function, although the stick seems to be in the middle. This deviation is interpreted as a small input by the MICROBEAST, which lead to an un­wanted rotation on that axis.

F Tail – torque precompensation (RevoMIX)
The advantage of always knowing the pitch and cyclic load on the flybarless system, allows the MICRO BEAST to pre-compensate for the torque variations on the tail before any noticeable deviation. This method of torque pre compensation (RevoMIX) relieves the tail control loop and improves the tail performance especially when using MICROBEAST on helicopters with insucient tail authority and/or extreme motor torque (well powered electric helicopters).

o user dened
To see the compensation direction, you can move the collective pitch, roll and elevator control stick at any time. With active feedforward the tail rotor has to produce a deection which is must counteract the rotor torque. Since at 0 ° pitch the least torque is applied by the main rotor, also tail rotor makes the least deection as no additional deection is added. If you pitch in positive or negative direction or move aile­ron or elevator control, a deection will be added to the tail rotor which must always act against the torque of the main rotor. For helicopters with clockwise rotating main rotor, the precompensation has to steer the tail always to the left (nose of the heli to the right). The deection will be held always in the same direction, whether positive or negative pitch, as the torque only increases. At 0 ° pitch and no cyclic control input the torque is at its lowest. Once a control input is given the tail slider / the tail rotor will move slightly (!) in a given direction. Cylce through the various op­tions and nd the direction (the color of Status-LED) that matches your model. You then have four options to set the precompensation (o, low, high or by computer).
Note: The height of the deection depends on the setting of collective pitch angles in Setup menu K. Therefore the deection may vary depending on the direction of pitch.
The choice is made by moving the tail stick into one direction until the Status-LED lights in the desired color.

G Cyclic response
With point G can be set how aggressive the MICROBEAST responds to cyclic control commands (roll and pitch). This can reduce the usual uniform and linear control feeling of ybarless systems and approach it to the feeling of a ybared helicopter.
If you want to use this feature, start from the “slightly increased“ setting, gradually increasing to the desired level, until you have found your ideal setting.
A too high setting will result in uncontrollable, inaccurate rotation and deteriorating stopping behavior of each control function.
How high this feature is adjustable without causing any adverse eects depends on many factors such as heli size, swashplate servos, main rotor blades, main rotor speed, servo power supply and depending on the particular heli setup.

Parameter point H allows you to set up the pitch boost function. This function causes that the faster you move the pitch stick the more additional collective pitch will be exposed. This can be especially useful in 3D aerobatics when very rapid pitch changes are necessary for certain ight maneuvers, as hereby dynamically the required control stick deection will be reduced.
However, the maximum set pitch value (Setup menu setting point K) will not be exceeded.
A too high setting can cause the rotor blades to stall when giving very fast pitch command. Also the collective pitch will feel slow and spongy, precisely cause the opposite eect as desired.
Start from the “low“ setting, gradually increasing to the desired level, until you have found your ideal setting. How high this feature is adjustable without causing any adverse eects depends on many factors such as maximum pitch values, pitch curve, swashplate servos, main rotor blades, system

10. THE FIRST FLIGHT
Now it‘s time to y your helicopter with the MICROBEAST!
After powering up the receiver, wait until the MICROBEAST has initialized completely.
This is indicated by a short move of the swashplate servos and the Status-LED lighting steady blue or purple. It is unnecessary to have the helicopter horizontal, but important not to move it during the whole initialization. In case of wind catching the blades, you can even lay it on the side to avoid shaking.
Like we mentioned in chapter 8 the three dials should be the factory setting (centered horizontally), when using in small helicopters for safety reason dials 1 and 2 should be set to slightly below the center position. The tail gain channel should be set to point F or G (in micro or mini helicopters experience has shown even lower). Select the control behavior at parameter menu point B to t your ying style.
Before the rst take o, make a stick direction check and again make sure that the sensors are cor­recting to the right direction when you tilt, roll or yaw the helicopter by hand.
It is normal that the swashplate might moving only slowly back to its original position after a stick input and that the servos don’t run at the same speed as your sticks.
In comparison to a ybar head you are not controlling anymore directly the servos but controlling ro­tational rates like for y-by-wire. The control of the servo is left to the control loop in the MICROBEAST. Thus it is also normal in HeadingLock mode, that the tail servo will stay in its end position after a tail stick input or tail movement and that it does not always react immediately to a stick input. For the same re­ason, it is also normal that the rudder servo runs to the endpoints with small stick inputs.
75
We recommend to remove main and tail rotorblades before the rst ight and let the motor/engi­ne run at all speeds. Caution: Risk of injury! Watch whether the swashplate automatically starts to tilt in one direction or begins to twitch at a specic speed. This usually is a sure sign that the helicopter mechanics vibrate at a very high frequent range which disturb the sensors of MICROBEAST.
Before the rst ight it is absolutely necessarily to prevent the cause of these vibrations. Often simply the attachment of the cables or MICROBEAST is not optimal, so that vibrations can very easily be transferred to the MICROBEAST.
Just before lift o make sure that the swashplate is horizontal and that the tail pitch slider is near cen­tered. You can shortly switch to Normal-Rate mode, in this mode the tail servo will always center itself if the tail stick is released.
Avoid excessive steering during lift o otherwise the helicopter may tip over!
The best way is to give a fair and direct pitch input to lift the helicopter quickly up into the air. This de­mands some re-education, if you have only own ybared helicopters before.
Now at rst you should try to nd the maximum possible tail gain and later on do some ne tuning as described in chapters 8 and 9 if necessary.

11. vERSION DISpLAY
After powering up the MICROBEAST, it performs a brief initialization phase. A quick LED test turns all menu LEDs on simultaneously, and the Status-LED cycles through all colors. Then for about 3 seconds, the Status­LED turns red and the rst two digits (X and Y) of the internal rmware version are displayed. Then, in the remaining time a running light of the LEDs A - G signals that the sensors are being calibrated and the LEDs H - N do indicate the initialization of the receiver signals.
During the initialization phase (i.e. when viewing the rmware version or later) push briey the button and you can display the third digit (Z) of the rmware version while the Status-LED ashes purple. Press the button briey again, and the color of the Status-LED changes to ashing blue while displaying the data version (X.Y). If you press the button third time, the Status-LED goes o and the hardware version (X.Y) of your MICROBEAST is displayed. Press the button once again to leave the version display and proceed with initialization.
Representation of values:
The representation of all values using the menu LEDs is in binary. A lighting menu LED stands for a 1, an o LED for 0. The least signicant bits are A and H.
Firmware version:
The firmware version consists of three values X.Y.Z which are displayed for X and Y during the ini­tialization, and for Z if the button is pushed during this initialization. X are displayed though menu LEDs A - G, Y through H - N and Z is using all LEDs A - N.
Data version:
The data version consists of two values X.Y which are displayed at the same time through menu LEDs A - G for X and H - N for Y.
Hardware version:
The hardware version consists of two values X.Y which are displayed at the same time through menu LEDs A - G for X and H - N for Y.

Description Reason Solutions
Selection in the menus with the rudder control stick does not work.
Too little control travel on the rudder channel.
Connector from the rudder channel inserted incorrectly.
- Increase the servo throw / dual rate for the rudder channel in the TX.
- Check that the connector for the rudder channel (orange wire) is inserted correctly in the receiver.
The sensors do not seem to work correctly.
The tail servo does not react or reacts very slowly to rotation of the helicopter. The same happens to the elevator axis.
Wrong mounting orientation has been selected.
The gain of tail gyro is too low in the transmitter or even not on the right channel
- In setup menu point A select the
correct mounting orientation.
- Adjust the Gain in the transmitter
- Correct wiring or setup of tail gain cable/channel.
The helicopter slowly drifts by itself on aileron, elevator and/or tail.
The swashplate is perfectly leveled and no sub trimming is present in the radio nor is any mixing function active.
This behavior seems to be inuenced by the rotor head speed.
This indicates to a vibration problem which interferes with the sensors of the MICROBEAST.
- Check the whole helicopter for imbalances
- In electric helicopters the motor can cause high frequent micro-vibra­tions
- Balance the tail rotor blades very accurately
- Check the tension of the tail belt
- Choose another mounting position for the MICROBEAST
- Try other types of gyro pads

Description Reason Solutions
The helicopter wobbles on aileron and elevator axis.
Reducing the swashplate gain does not help to suppress this eect completely.
The MICROEBAST setup is not done correctly.
The helicopter‘s linkage ratio is not suitable for ybarless usage.
The servo-blade combination is not good
Some linkages aren’t moving smoothly and freely.
- In setup menu point J adjust the
cyclic pitch to exactly 6 degrees: the color of the Status-LED should be “blue”, otherwise the linkage ratio has to be changed by using longer blade grip levers, shorter servo horns or shorter linkage balls at the swashplate.
- Check if the swashplate travel for aileron and elevator is not too much limited at setup menu point L: try to achieve a larger travel by changing the linkage ratios.
- Use faster and stronger servos and/ or specic ybarless blades.
- Check the mechanics for any hard points. (ball linkages, blade grips)
- Check if the dampers are greased
- Check that the thrust bearings in the blade grips are correctly mounted.

Description Reason Solutions
The tail oscillates in horizontal position slowly and irregularly while hovering.
The HeadingLock gain is too high.
- Reduce the HeadingLock gain in
parameters menu point D by one step and increase the tail gain at your transmitter.
- Check the linkage and mechanics for absolute free movement without hard points.
The tail oscillates in vertical position.
This oscillation is caused by the rotor head.
- Decrease cyclic gain (Dial 1).
- Use another rotor head dampening that better ts to rotor head speed (the higher the head speed, the harder the dampening should be).
During slow hovering pirouettes, the helicopter is rolling out.
The pirouette optimization setting is wrong
- Adjust the pirouette optimization in setup point N correctly.
Status-LED ashes in operation mode, e.g. after landing.
During operation a software - reset occurred.
- The receiver power supply does not
seem to be sucient. The voltage during operation dropped in a critical area or there was a discharge or transfer of high voltage.
