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.
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 fly in the rain or extremely high humidity. Do not expose the MICROBEAST-System to extreme variations in temperature.
GENERAL INFORMATION Please note that these instructions are only valid for the MICROBEAST firmware Version 3.x.x ! The delivered software version is printed on a sticker on the outside of the MICROBEAST packaging.
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 fly R/C helicopters without a mechanical flybar. This brings a boost in power as well as longer flight times and makes it possible to adapt the agility and flying behavior of your helicopter to your individual preference.

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 flat or upright, and even upside down under the helicopter.
3.2 Preparing a transmitter for flybarless (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.
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. Fig.
4. Receiver connection In relation to the control of MICROBEAST you have the opportunity to use different 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 five control channels between MICROBEAST and receiver.
4.1 Connection of a standard receiver Top receiver outputs 4.1.1 Flybarless usage Pitch (red) Fig. 4 Rudder (orange) Tail Gain (brown) Elevator Aileron Elevator servo Aileron servo 1 Aileron servo 2 / Pitch Tail servo Now plug the receiver cables for aileron, elevator, pitch, rudder and tail gain between the MICROBEAST and the receiver. To find out the channel assignments of your remote control receiver, please refer to the user manual of your transmitter or contact its manufacturer.
AUX2 red AUX1 brown GEAR JR / Spektrum RUDD RECEIVER orange ELEV AILE THRO FUTABA RECEIVER 7 red 6 brown 5 4 orange 3 2 1 Abb. 5 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.
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.
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 Spektrum® 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.
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.
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.

LED H + all menu LEDs flash LED N + all menu LEDs flash switch off power supply remove Bind Plug Fig.
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 fixed to the receiver (e.g. Jeti ® satellite receiver).
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.
5. Receiver type setup Beside using conventional receivers, the MICROBEAST supports the use of different types of single-line receivers. These are receivers which transmit the control signals only over one single cable wiring. If using such a receiver because of the different signal protocols the receiver type must be selected in the receiver menu before the first use and further steps such as allocation of individual channels or failsafe setting are needed.
convention: LED lights: LED is flashing: Then press the button, but only briefly, to save the setup and switch to receiver menu point B. If you have already briefly pressed the button by mistake and it did not change the receiver type but switch to menu point B, switch off the power and repeat the above procedure.
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.

Receiver menu point Function B pitch C aileron D elevator E rudder F tail gyro gain G throttle (CH5) H auxiliary (CH6) 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 confirms it with blue flashing 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.
If the Status-LED stays red, it means that there is no valid remote control signal available. In this case, a channel assignment 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 off the power and re start the receiver type procedure. Fig.
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 operation, 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 “off“ and reduce throttle on nitro helicopters to idle.
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 firmware 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.
Never fly while the MICROBEAST is in one of the setup or parameter menu! In this condition the gyro control and the stick controls are disabled.
6.1 Setup menu No Menu LED is on Push button for about 3 seconds Operation mode Fig. 16 Menu LED A steady on Setup menu – menu point A 6.2 Parameter menu no Menu LED is on Press button shortly Operation mode 34 Fig.
6.3 Example: Selection within the menus Status-LED: By moving the tail stick to the left or right, you can select the different options within a menu point. off purple flashing red blue flashing blue red The number of possibilities depends on the menu point. Fig. 18 6.4 Switching to the next menu point Fig.
7. SETUP MENU Before the first flight 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 flash 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.
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 flying 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).
B Swashplate servo 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. If you do not know what the maximum pulse rate tolerated by your servos is, please select not more than 50Hz driving frequency.
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 defined” allows you to define your own setting with the PC software. The MICROBEAST can be used with nearly all available servo types. However, the selected servos should be adequate for flybarless operation (high torque and also fast and precise). The quality of the servos will have a direct influence on the range of rotor blades that can be used.
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 different center position pulse length. There is a relationship between the setting of the tail servo center position pulse length and the tail servo frequency (menu point D).
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. 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 verified in the datasheet of the servo.
The option “user defined” allows you to define your own setting with the PC software. 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.
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.
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 flashing followed by lightning steady purple, (mix of red and blue) indicating that the servo endpoint adjustment is complete. Fig.
F Setting the Tail sensor direction Here you have to check if the MICROBEAST‘s tail gyro does compensate into the right direction. At setup point F, you can find 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.
Once again repeat the test as described above. The MICROBEAST should now correct in the right way: wrong ste er correct rotation in gd ire ct ste er rotation in gd ire io n ct io n Fig. 24 Push the button to save the configuration and to proceed to setup menu point G. If using the MICROBEAST as a stand-alone tail gyro with the optional patch cable (see chapter 3.5) you do not have to do any further adjustments within the setup menu.
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 off. 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.
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). Fig. 25 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. Fig.
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 off the “electronic swashplate mixer” option.
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.
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.
1. Orientate the rotor blades parallel to the longitudinal axis of the helicopter. Fig. 28 2. Adjust the cyclic pitch to exactly 6 degrees. Move the aileron stick until 6 degrees (+ or -) of cyclic pitch is reached Fig.
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.
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 deflection 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 swashpla te, the linkage rods or servos are binding somewhere or even getting not more driven.
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 verified 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. When tilting the helicopter forward the swashplate has to move backwards, when tilting the helicopter to the back, the swashplate has to compensate forward.
Tilt the helicopter forwards The swashplate has to move backwards Fig.
Roll the helicopter to one side The swashplate has to steer to the opposite direction Fig.
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 fig. 32 on the next page). The initial direction (forward or backward) is irrelevant.
1. Swashplate points to the left 2. Rotate the helicopter around the vertical axis 3. Swashplate must still point left, as before Fig.
8. DIALS AND TAIL GYRO GAIN Status-LED Tail gyro mode off, blue flashing, blue = HeadingLock purple = Normal-Rate mode Menu LEDs: The amount of tail gain A=0% to N=100% (only after powering up or when adjusting the gain) Dial 1: cyclic gain Dial 2: direct cyclic feed forward Fig. 33 Dial 3: tail dynamic To adjust the dials please only use the original plastic BEASTX adjustment tool to prevent damage to the dials! 8.
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 efficiently by only having to make residual corrections. Factory setting of the dial is horizontal which provides a good setup in most cases.
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 flashing blue indicates HeadingLock mode.
9. PARAMETER MENU When the MICROBEAST is ready, hold down the button until the Menu LED next to point A flashes quickly and then release the button. This is how to enter the parameter menu. To switch to the next parameter menu point, just briefly 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 flight again. Status-LED will indicate the tail gyro mode and the LEDs A - N are off.
A Swashplate cyclic center adjustment The first menu point in the parameters menu gives you the possibility to easily adjust your servo centers on the flying field 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.
B Control behavior At parameter menu point B you can choose between different 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 first flights.
When using the predefined control behaviors we do not recommend to additionally adjust control curves (Expo/Dual rates) in your transmitter as this will mix indefinable 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.
C Swashplate – pitching up compensation While in fast forward flight 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 effect. But, if the value is too high the helicopter might feel sluggish and lazy. Try to find the lowest suitable setting.
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 find out the highest possible tail gain in your transmitter.
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).
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.
F Tail – torque precompensation (RevoMIX) The advantage of always knowing the pitch and cyclic load on the flybarless system, allows the MICROBEAST 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 insufficient tail authority and/or extreme motor torque (well powered electric helicopters).
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 flybarless systems and approach it to the feeling of a flybared 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.
H Pitch boost 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 flight maneuvers, as hereby dynamically the required control stick deflection will be reduced. However, the maximum set pitch value (Setup menu setting point K) will not be exceeded.
10. THE FIRST FLIGHT Now it‘s time to fly 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.
We recommend to remove main and tail rotorblades before the first flight 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 specific 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 first flight it is absolutely necessarily to prevent the cause of these vibrations.
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 first two digits (X and Y) of the internal firmware version are displayed.
12. TROUBLE SHOOTING Description Reason Solutions The MICROBEAST does not initialize. The MICROBEAST signals a sensor failure -H elicopter must stand absolutely still during initialization process. The Status-LED is flashing red. - S trong wind can shake the helicopter and therefore the sensors. Lay it on the side during the initialization. -D on’t initialize on a vibrating support, like a car hood or trunk with a running motor. Turn off the motor! - S ensors are damaged.
Description Reason Solutions Selection in the menus with the rudder control stick does not work. Too little control travel on the rudder channel. - Increase the servo throw / dual rate for the rudder channel in the TX. Connector from the rudder channel inserted incorrectly. - Check that the connector for the rudder channel (orange wire) is inserted correctly in the receiver. The sensors do not seem to work correctly. Wrong mounting orientation has been selected.
Description Reason Solutions The helicopter wobbles on aileron and elevator axis. The MICROEBAST setup is not done correctly. - I n 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. Reducing the swashplate gain does not help to suppress this effect completely.
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).
