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

saety rules or R/C models and the local law. You can gather inormation rom your local R/C model

club or rom your national modelers association.

Pay attention to your own saety and the saety o other people and property in your vicinity when

using our product. Always y in areas away rom other people. Never use R/C models in close proximi-

ty to housing areas or crowds o people. R/C models may malunction or crash due to several reasons

like piloting mistakes or radio intererence, and cause severe accidents. Pilots are ully responsible or

their actions, and or damage or injuries caused by the usage o their models.

The MICROBEAST-System is not a ying aid or 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 o R/C helicopters. Otherwise we suggest you to seek the support o

an experienced helicopter pilot beore you undertake the rst ight o your model. Additionally, ight

training with a R/C simulator can help make ying easier and more enjoyable. Ask your local dealer i

you need technical support or i you observe problems during the usage o our system.

Please read the ollowing instructions thoroughly beore the rst use o your MICROBEAST and

setup the system careully according to this manual. Allow sucient time or the setup procedure and

check each step careully. Watch or a mechanically clean and proper build o your helicopter. A wrong

system setup can lead to a serious accident and damage to the model.

Radio controlled (R/C) models consist o several electrical components. It is thereore necessary to

protect the model rom moisture and other oreign subtances. I the model is exposed to moisture this

may lead to a malunction 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. Beore powering up

the system, wait some time so that the electronics can acclimatize and any accumulated condensation

is able to evaporate.

MICROBEAST consists o highly sensitive electrical components with limited capability to operate

with excessive vibrations or electrostatic discharges. I you nd such disturbances in your model, the

use o MICROBEAST should be postponed until the problems have been xed.

When operating the helicopter with a MICROBEAST ensure there is a suciently large and stable

receiver power supply. Because o the direct coupling o the rotor blades to the servos, without the use

o a ybar mixer, the servos are exposed to increased actuating orces. In addition, because o the inter-

mediary electronic gyro system, the servos are driven more oten than with traditional use.

Ths actors can mak th powr consumption incras a lot compard to a yar hlicoptr

Particularly when operating electric helicopters with single-line receivers, make sure that the elec-

tric motor cannot start inadvertently during the setup procedure, i the ESC is connected directly to the

MICROBEAST. We recommend disconnecting the electric motor rom the ESC during the setup proce-

dure. Prior the rst usage please slide the motor/pinion away rom the main gear, then check that the

motor does not to start inadvertently when the receiver is switched on.

1. INTRODUCTION

Dar customr, thank you or choosing th MICRObeAST!

MICROBEAST is an easy to use three axis gyro system which makes it possible to y R/C helicopterswithout a mechanical ybar. This brings a boost in power as well as longer ight times and makes itpossible to adapt the agility and ying behavior o your helicopter to your individual preerence.

The MICROBEAST has a built-in high end tail gyro based on the latest MEMS Technology which givesyour helicopters tail perect stopping behavior and constant rotation rate during any manoeuvers.

The MICROBEAST can be used in nearly any size o helicopter, using either electric motors or nitro en-gines or propulsion. It provides ight stability or beginners and maximum agility and precision orintermediate and proessional pilots.

Nevertheless, the MICROBEAST is not a ying aid or beginners! I you are inexperienced with modelhelicopters, please consult an experienced pilot or help with setup and your rst ights.

The ollowing manual will lead you step by step through the setup procedure rom the correct moun-ting o the unit up to the rst ight. Please read the ollowing instruction manual thoroughly. You willsee that during the development o the MICROBEAST, that our ocus is to user riendly and soon youwill be able to operate the system intuitively.

The included overview map o the setup menu can be taken out to the ying eld as a quick reerenceto the various menu options.

Check our website WWWbeASTXCOM where we will inorm you about the latest updates and down-loads.

Now have un and a good time using MICROBEAST!

3. MOUNTING AND CONNECTION

31 Mounting th MICRObeAST unit

Attach the MICROBEAST unit by using one o the provided gyropads at apreerably low vibrating position on your helicopter such as the gyro platorm orreceiver platorm. You may also need to choose another type o mounting paddepending on the vibration pattern o your helicopter. Ask you MICROBEASTdealer.

The MICROBEAST unit can be attached at or upright, and even upside downunder the helicopter. Howvr, th srvo connctor pins must always pointtoward th ront (or rar) o th hlicoptr

Pay attention that th dgs o th MICRObeAST unit ar all paralll with thcorrsponding axs o th hlicoptr! And be sure that the mounting platorm is perpendicular tothe main shat!

32 Prparing a transmittr or yarlss

(This step is unnecessary when using the MICROBEAST with the optional cable or stand-alone tail gyro use.

Please see 4.1.2)

First create a new model in your radios model memory. When using the MICROBEAST you have to disableany mixing unctions or the swashplate or tail. Each unction should be assigned to just one receiver chan-nel. As you see our requirement or the transmitter is very low.

Be sure that all trims and sub trims are disabled and that all servo travel are 100% (increasing or decreasingthe servo travel or aileron, elevator and rudder can later adjust the maximum control rates, see chapter 9-B ).

Never enable your radios eCCPM mixing unction: this will be done by the MICROBEAST. Always set yourradios swash mixer to mCCPM (mechanical mixing) which is oten 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 rom-100% to +100% (or 0 to 100% depending on radio brand).

Again make sure that there are no mixing unctions active (or example revo-mixing).

Other unctions such as throttle curves, ESC switches or auxiliary unctions can be adjusted as usual.

33 Srvo connctions and auxiliary channls

In slot CH1 is the elevator servo. With electronic swashplate mixing the two roll servos have to be con-nected 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.

Dont plug th srvos into th MICRObeAST yt! Th corrct srvo typ and appropriat drivingrquncy has not yt n slctd in th Stup mnu We recommend not installing the servohorns 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 theMICROBEAST. Make sure that the MICROBEAST is able to move reely, so no vibrations getpassed onto the unit.It is not recommended to bundle or tie down the leads clos to the MICROBEAST.On the other hand the wires must be attached so that they are unable to move the MICROBEASTduring the light. In particular, do not use any shrink tubing or abric 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 sti and inlexible and can cause even the slightest vibrations are trans-mitted to Microbeast.

At this point w would lik to point out that th corrct dimnsioning o rcivr powr supply is vryimportant (beC and attry currnt rating, numr o supply cals, cal diamtr, cal lngth )For yarlss hlicoptrs, th load on th srvos and th rsulting powr consumption is signicant-

4. RECEIvER CONNECTION

In relation to the control o MICROBEAST you have the opportunity to use diferent types o receivers.It is distinguished between conventional standard receivers and socalled single-line receivers:

A standard rcivr is a receiver that is connected to the MICROBEAST by using any single servo output othe receiver to connect the ve control channels between MICROBEAST and receiver. The channel whichdetermines the controlled unction simply is selected by inserting each plug to the correct output at thereceiver. In section 4.1.1 it is shown how to exactly connect the receiver to the MICROBEAST when using theMICROBEAST as ybarless system. In addition the use o 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 singl-lin rcivr all channels are transmitted by one single connection line to theMICROBEAST. Because o this, it is not possible here by inserting the appropriate plugs in the receiver toassign unctions to the MICROBEAST. This must be done by a specic setting in the MICROBEAST (describedin chapter 5).Also single-line receivers similar to standard receivers with additional single channel connectors areavailable. Thereore you only have to treat such receivers as single-line receivers in combination withMICROBEAST i you really use this unction.

How diferent types o 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 thereore is not described urther in the ollowing.

41 Connction o a standard rcivr

411 Flyarlss usag

Now plug the receiver cables or aileron, elevator, pitch, rudder and tail gain between the MICROBEASTand the receiver. To nd out the channel assignments o your remote control receiver, please reer tothe user manual o your transmitter or contact its manuacturer.

To connect lvator and ailron, use the plain 3-wire cables that transmit the control signal in

addition to the power supply rom the receiver to the MICROBEAST.Pitch (red), tail (orange) and gain (brown) have only one lead or the control signal on the receiver side, andare connected to the MICROBEAST on the combined connector. Please ensure these plugs are connectedcorrectly to the receiver. Although the cable color is diferent, all three wires are signal lines, which go to theusual orange, yellow or white side! + and - remain open on theses channels.

Please respect the polarities or the plugs going to the MICROBEAST. The orange line on the MICROBEASTmust always be on the top and the brown on the bottom. Also sur whn insrting th connctors

412 Usag as stand-alon tail gyro

The MICROBEAST can also be used as high-end stand-alone tail gyro. This requires the use o a special patchcable which can be purchased separately. This ensures that the MICROBEAST is provided with power andthat the signals or rudder and tail gain are available rom the receiver.

The signal lead with the orange and yellow wires must be connected to the slot[ Aux | Pit | Rud ]. The orange wiremust be closest to the topside o the MICROBEAST.

The power lead must be plugged into the slot [ eLe | DI1 ]. The brown wire (negative or ground) is on thebottom, the red wire (positive or power) should be in the middle position. Connect the tail servo to [ CH4 ].

42 Us o singl-lin rcivrsThe MICROBEAST enables the use o conventional receivers with individual channel outputs or the use ospecial receivers which output the channel signals as a merged single-line signal. These include Spektrumsatellite receivers, PPM composite signal receiver (e.g. Futaba SP Series receiver or the satellite receiver rom

Jeti ), receivers with Futaba S-BUS as well as receivers with SRXL compatible data output (e.g. SRXL-Multiplex or BEASTRX).

421 Gnral nots

When operating with single-line receivers (Spektrum satellite receiver, PPM composite signal receiver- e.g. Futaba SP-series or the satellite receiver rom Jeti, receivers using Futaba S-BUS, SRXL

compatible receivers), the throttle servo/motor controller can be connected to [CH5] on theMICROBEAST. When using a motor controller or electric models with a BEC this slot then also will besupplying the MICROBEAST, the servos and the receiver with power.

We recommend i possible (e.g. on all receivers that have normal servo connectors together with singleline output) to connect the throttle servo/motor controller directly to the receiver to benet rom thenative Failsae/Hold unctions. Although the MICROBEAST also has adjustable Failsae or [CH5] this will

only be activated when the connection between MICROBEAST unit and receiver ails but not orexample in case o signal loss between transmitter and receiver.

On slot [DI2 | CH7 | CH6] another auxiliary channel is available on the top pin [CH6], or example tohook up a governor or nitro engines. Please note that this slot is only issuing a control signal and hasno power. For this reason a servo cannot be plugged here directly. The two lower pins [DI2] and [CH7]are reserved or other applications. Nvr connct a powr sourc on thos two pins: this could

damag th MICRObeAST!

In the case o an electric model i the ESC has a second BEC output or when using a bufering batterythis wire can be connected to the [SYS] terminal or (i possible) plugged directly into the receiver.

On models with a separate power supply this can only be connected to the MICROBEAST on slot [SYS].Thereore please ensure adequate sizing o the supply lines, especially with large models. A secondpower connection can be derived to the receiver or, by using a Y cable, you can inject a parallel powersupply to one o the servo outputs. When using very powerul servos you might even consider using aseparate voltage regulating unit that the servos can be connected to.

422 Spktrum Satllit rcivr

To connect a Spektrum satellite (remote) receiver on the MICROBEAST a special optional adapter isrequired. This adapter is connected to the [DI1] input o the MICROBEAST. Please observe correctpolarity, the orange signal line must be next to the cover. The cable or the Spektrum satellite receiver

is then plugged into this adapter.

binding procdurIn the case o using a Spektrum satellite receiver it is very important to bind the receiver irstbeore programming the MICROBEAST. This stp is ssntial to prorm, even i the satellite wasalready 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.

Simultanously with th inding procss, th typ o satllit rcivr has to st, iwhthr it is a DSMX or DSM2 satllit (Th actual slctd signal protocol in th transmittr

is not rlvant!) It is vry important to choos th corrct typ o satllit rcivr hr,sinc an impropr stting may sm to work ut can lad to radio intrrnc or total losso th link in th susqunt opration!

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 re-ceiver, the power supply must be provided temporarily through any o the servo port (CH1 - CH5).

To select a DSM2 satellite and to enter bind mode, simply switch on the power supply now. TheLED on the receiver and LEDN on the MICROBEAST will start to ash. You can bind the transmitteras usual (or more inormation reer to the instructions o your radio control system).

To select and bind a DSMX satellite, hold down the button on the MICROBEAST while switchingon the power supply. Now the receivers LED and LEDH (!) on the MICROBEAST will ash and youcan release the button and bind the receiver with your transmitter.

Ater successul binding procedure the receivers LED will stay solid. LED H respectivelyN ash

alternately to all other LEDs. Now switch of the power supply and remove the bind plug. Nowcontinue with receiver type setup (see next chapter).

Note: It makes no dierence i you pull o the Bind Plug during the binding process or leave it

connected as you would expect rom some standard Spektrum receivers.

Watch out that th motor can not start accidntally whn using th beC of your spd controllrto powr th unit!

423 Conncting singl lin rcivrs without additional srvo outputs(g PPM composit signal rcivrs)

For the connection o PPM composite signal receivers there is usually no special adapter required. Inmost cases (e.g. Futaba -receivers o the SP-series) the receiver can be connected to the MICROBEAST

with one o the supplied regular 3-wire cables. For some receivers, the connecting cable is also alreadyxed to the receiver (e.g. Jeti satellite receiver).

I not xed to the receiver, plug the cable into the output o the digital composite signal o your receiver,usually labeled with SIG or the like. Again pay attention to correct polarity. Be careul, since the sup-plied cable is designed to be used universally, and the usual Futaba polarity protection tab is mis-sing.

Plug the other end o the cable into the MICROBEAST input [DI1]. Make sure the polarity is correct; theorange signal line must be next to the MICROBEAST top cover.

5. RECEIvER TYpE SETUp

Beside using conventional receivers, the MICROBEAST supports the use o diferent types o single-linereceivers. These are receivers which transmit the control signals only over one single cable wiring. Iusing such a receiver because o the diferent signal protocols the receiver type must be selected in the

receiver menu beore the rst use and urther steps such as allocation o individual channels or ailsaesetting are needed. You can see rom the yellow LED next to the lettersA -N at which receiver menupoint you are currently in. By briey pressing the button you can go to the next receiver menu pointwhich also saves the current settings.

52 Input channl assignmnts (rcivr mnu pointsB -H)

I not a standard receiver but a single-line receiver was selected at menu pointA, it must be establishedwhich control unction is controlled by what channel. This is necessary because all the control unctionsare transmitted via one single line and thus there is no possibility o plugging the cables in each

individual channel matching at the receiver.

521 Prst channl assignmnt

When selecting a specic type o single line receiver the appropriate type o receiver channel allocationwill be preset in the MICROBEAST. Please reer to the tables below and check i your radio transmits thechannels in the correct order. I this is not the case, you have to assign the channel order step by stepthrough the menu pointsB -H (or this see section 5.2.2). To know th channl assignmnt o your

transmittr you can chck th usr manual o th transmittr or look at th srvo monitor o thtransmittr (i it has this atur) I in dout ask th manuacturr o your transmittr

When using SRXL the preset channel assignment is based on the receivers protocol version (see nextpage).

522 Taching o customizd channl ordr

I you need a customized channel order, please rst prepare (i not already done) your transmitter asdescribed in section 3.2 .

Additionally, mak sur (or xampl, using th srvo monitor o your transmittr) that ach controlunction o your transmittr activats on and only on channl This can be tricky especially orthrottle/pitch unctions which are usually coupled by a mixer in the transmitter. In this case set the throttlechannel quiet by using or example the throttle hold switch or provide a at throttle curve so that the pitchstick actually controls only the channel or the pitch servo, but or the later, keep the possibility to controlalso the throttle channel by ipping a switch or example.

In the ollowing 7 menu pointsB -H, you can assign diferent unctions by simply actuating the appropriatechannel unction on your transmitter. A blue ash o the Status-LED indicates that a channel has beendetected. It does not matter how ar or in what direction you move the stick or in what position the stick/switch was. Note the channel value itsel is not important, but the change o this value is. It is thereoreimportant that only the requested unction is activated and not by accident several simultaneously.Otherwise, the MICROBEAST may not recognize the allocated channel correctly.

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 pointwithout any binding or stall and release the tail stick.

Which kind o CCPM your helicopter uses can be read in the manual or your helicopter.

The color and state o the Status-LED shows the currently selected mixing type:

At setup menu pointI, you adjust the correct swashplate servo directions. To acilitate this setup, youdont need to adjust every servo by its own, but just try the 4 possible combinations.

Move the pitch stick and check i the swashplate moves horizontally up and down. The direction itselis not yet important. I one or more servos are not running in the right direction, just choose anothercombination by giving a short rudder input. Repeat this rudder input until all servos are running in thesame direction.

At this setup pointJ, you have to tell the MICROBEAST the available cyclic pitch range.

First dont touch any stick on your transmitter when entering setup menu point J. Orientate one othe rotor blades so that it is parallel to the tail boom (Fig. 28). Then attach a pitch gauge to this rotorblade. The swashplate should be in the neutral position and the blades should have 0 degrees o pitch,otherwise repeat the swashplate servo centering at setup menu pointG.

Now move the aileron stick until the rotor blade has an exact 6 degrees o cyclic pitch and then releasethe stick ( Fig. 29). I you moved the swashplate too ar you can steer the stick to the opposite directionand 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 6when you save and leave this menu step. It is not enough to go to 6 and then move back beore savingand leaving.

Whn raching 6 dgrs, th Status-LeD should light lu This indicates that your helicopters

rotor head geometry is perect or the use with a ybarless system. Otherwise, i the Status-LEDs coloris red or purple or even i the Status-LED is of, this indicates that your helicopters geometry is notoptimal or ybarless usage. Correct this by using shorter servo horns, shorter linkage balls on the innerswashplatering or longer blade grip link levers.

Always st th cyclic pitch to 6 dgrs! This setup does not afect the maximum rotation

rate o the helicopter but is only there to show the MICROBEAST the actual mechanical cyclicgeometry. A wrong adjustment at this step may be extremely detrimental to the perormance othe MICROBEAST. The blue color o the Status-LED is secondary and just or inormation.

1. Orientate the rotor blades parallel to the longitudinal axis o the helicopter.

At setup pointK 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 amounto pitch using the tail stick.

When you adjusted the desired maximum pitch angle, move the pitch stick all the way down and again in-crease or decrease the pitch to the minimum desired value using the tail stick.

Dont use any pitch curves in your transmitter whil doing ths adjustmnts. Later on or the ights,you can adjust your pitch curves as you like and are used to. Setup menu pointK solely serves to teachthe MICROBEAST the maximum used pitch range.

At this point, veriy again that the demanded pitch direction on the transmitter is in the correct

direction or the model. Otherwise use your transmitters servo reversing unction or the pitch channelto correct this as already described in sectionI.

L Adjusting th cyclic swashplat limit

At setup menu pointL you adjust the maximum possible tilting o the swashplate or aileron and elevator The


54/88

54

At setup menu pointL you adjust the maximum possible tilting o the swashplate or aileron and elevator. Thedeection will be limited in a circular path similar to a cyclic ring unction.

For adjustment proceed in the ollowing way:Careully move the sticks or aileron, elevator and pitch to all maximum end points and watch out i the swashpla-te, the linkage rods or servos are binding somewhere or even getting not more driven.

By moving the rudder stick to the let 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 deection is set the greaterit will be in ight. This will achieve the maximum possible rotation rate o the helicopter without sacricing the

gyro control loop.

I aterwards any modications are done to one o the other setup menu points which afect servo

adjustments (setup menu pointsG,J andK) the cyclic swashplate adjustment has to be redone.

Push th utton to sav th conguration and to procd to stup mnu pointM

Similar to setup pointJ, the color o the Status-LED indicates whether the adjusted limit allowssucient cyclic throw. In the ideal case, the swashplate is limited only to the extent where the Status-LED still lights blue. In particular, or models that are intended to be used in 3D aerobatics, 10 to 12cyclic throw should be possible. But even or all the other helicopters, it is recommended to adjust asmuch throw as possible, because otherwise the control loop may not work properly. Here, the color othe Status-LED provides a clue. I you get only purple or even no light at all, it is essential that youchange the mechanical setting o your model to increase the available throw.

M Stting th swashplat snsor dirctions

55/88

55

At setup menu pointM, you check i the sensors or aileron and elevator are working in the correct direction.

This can be directly veried in this menu point: I you roll or tilt the helicopter by hand the swashplate has to steer

against this movement. Please reer to this on the next pages Fig. 30 and 31.

I this is not correct, you can reverse the sensor directions by moving the tail stick in one direction. Forconrmation you will see that the Status-LED changes color. Repeat this step until both sensors arecorrecting in the correct direction.

There are our possible displays or control to choose rom, one will be correct:

When tilting the helicopter orward the swashplate has to move backwards, when tilting the heli-copter to the back, the swashplate has to compensate orward. Same thing applies to the roll axis,when you roll the helicopter to the let the swashplate has to steer right and vice versa. Basically theswashplate has to remain horizontal while banking the helicopter.

To adjust th dials plas only us th original plastic beASTX adjustmnt tool to prvnt damag toth dials!

81 Swashplat: cyclic gain (Dial 1)

Turn dial 1 clockwise to increase the swashplate gain.

The actory setting or 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 250or 450 size), reduce the swashplate gain slightly.

In general the higher the gain the harder the helicopter will stop ater cyclic moves and the helicopterwill eel more stable in the air. I the gain is too high the helicopter eels spongy and tends to oscillateespecially on the elevator axis.

I the gain is too low the helicopter does not stop precisely ater a cyclic movement and eels unstablein ast orward ight.

input that is going directly to the servos. I correctly adjusted, this relieves the control loop which will workmore eciently by only having to make residual corrections. Factory setting o the dial is horizontal which

provides a good setup in most cases.

Increasing the direct cyclic eed orward will cause more cyclic stick input going directly to aileron and elevatoron the swashplate. Decreasing the direct stick eed orward will do the opposite.

I the direct cyclic eed orward is too high, it will over control your cyclic input. The control loop needs theneventually to steer back. Even though you get the impression to have a more direct control, unwanted sideefects may appear, like pitch backs on cyclic stops and imprecise ast orward ight.

I the direct cyclic eed orward is too low, the helicopter will eel soter, slower and less direct. The optimalpoint depends o many actors like blades, servos, head speed, size and mass o the helicopter.

At delivery the dial is in the middle which should be a good starting point or most helicopters.

83 Tail dynamic (Dial 3)

Turn dial 3 clockwise to increase the tail dynamic. Turning dial 3 counter clockwise will decrease the taildynamic. Factory setting o the dial 3 is horizontal which provides a good setup in most cases.You haveto make sure the maximum possible tail gyro gain has already been determined (see section 8.4) beo-re adjusting the tail dynamic.

Increasing the tail dynamic will lead to harder stopping behavior and more aggressive response to tail stickinputs. I the dynamic is too high the tail will bounce back shortly ater a hard stop and eel spongy

when making ast direction changes. I the dynamic is set too low the tail eels dull and stopping might betoo sot. Ideally the tail should stop perectly to the point without making any apping noises.

The direct cyclic eed orward does not afect the maximum rate o rotation! I the helicopter turns

too slowly, you should check the settings o the swashplate limiter in setup menuL, change thecontrol behavior in the parameter menu at pointB, or increase the servo travels or Dual Rate setupin your remote control.

84 Tail gyro gain (adjustd y th transmittr)

As with a conventional tail gyro, the tail gain can be adjusted by one o the transmitters auxiliary channels. Inone direction you can select the Normal Rate mode and in the other direction HeadingLock mode


62/88

62

one direction you can select the Normal-Rate mode and in the other direction HeadingLock mode.

Th color o th Status-LeD indicats th slctd mod whn th MICRObeAST is rady or opration

Purple indicates Normal-Rate mode and blue or exceptionally ashing blue indicates HeadingLock mode.Additionally while adjusting the gain or shortly ater the rst start up, the current amount o gain is displayedby one o the menu LEDs or about 10 seconds. So you always know the actual amount o gain in your helicopteras percentages will depend o the used transmitter. When the gain channel is centered, this will correspond to0% gain indicated by LEDA. In both modes, the maximum adjustable tail gain is 100% and will correspond toLEDN, 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 thenF orG in HeadingLock mode. To nd theoptimal gain, we recommend starting with a low gain, where the tail will eel very weak and will stop withovershoots. Then increase the gain step by step and you will eel the tail having more and more precise stops,and hold better and better on jerky pitch inputs. I the gain gets too high, the stops will bounce back quicklyand wagging will appear in ast orward or backward ight.

Operation without using a sensitivity (gain) channel is not possible!

Nvr us th trim unctions o your rmot 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 pointG, here you are able to directly adjustaileron and elevator without taking care about the single servos. However, the collective pitch cannotbe adjusted here.

Similar to the digital trim unction o most transmitters here at parameter menu point A you canadjust the swashplate one click by shortly moving the aileron or elevator stick in the desired direction.I you want to trim the swashplate any urther repeat tapping the stick several times or simply hold the

control stick pushed or a longer time to automatically perorm several trim steps.

During the sub trim procedure you can delete the just perormed trimming by moving the tail stick inany direction. Additionally the color o the Status-LED gives you an approximate indication o howmuch you did trim.

But remember that this unction as opposed to the digital trim o the transmitter is not

a separate trim unction. Here you directly adjust the servo centers as well as you would set servocenters in the setup menu pointG. I the new position is saved once then this corresponds well to thenew servo center position in the setup menu pointG. A subsequent reset to the previous state is notpossible anymore!

Additionally when using the setting transmitter by increasing the tail stick throw, in HeadingLockmode you get to an additional eature where the tail rotation rate is not limited by the gyro anymore.With this eature, extremely high tail rotation rates are possible. The state o the Status-LED shows i thishigh rate mode is reached. I the LED starts to ash at ull tail stick input, you are on the controlledrotation rate limit. I you increase the tail stick servo travel urther, the Status-LED will end up turningof when at ull stick input. From this point on the rotation rate is no longer limited by the maximumgyro sensor capability, and you get into a ree spinning area that can not be controlled by the gyro

anymore. By urther increasing the stick input (dual rates, or servo end points), the maximum rotationrate will increase even urther, as ar as the mechanics o the helicopter will allow it!
