''I am trying to access the menus but if I press the button either after powering on or before, the A light never goes solid or blinks. Also if I hold it for 10 seconds it doesn't appear to perform the factory reset.''

''I am trying to access the menus but if I press the button either after powering on or before, the A light never goes solid or blinks. Also if I hold it for 10 seconds it doesn't appear to perform the factory reset.''

To enter one of the menus you have to wait until the unit did perform the self test and did fully initialize: The Status LED must get blue or purple and the cycling LEDs A to G and H to N must have stopped.

Um in eine der Menüebenen zu gelangen muss das Gerät vollständig initialisiert haben. Dies erkennt man daran, dass das Lauflicht zwischen den LEDs A bis G und H bis N vollständig erloschen ist und nur noch die Status LED blau oder violett leuchtet. Erst dann kann man durch einen kurzen Tastendruck in das Parametermenü eintreten oder durch einen längeren Tastendruck das Setupmenü aufrufen.

Factory reset only can be performed when being within Setup menu. So you have at least to get to Setup menu point A (or later), release the button and then push it and keep it pushed for at least 10 seconds. Note that factory reset will only revert all parameters of parameter menu and setup menu to default. It has no influence on receiver menu parameters. If the unit does not initialize due to wrong receiver setting the factory reset will not help. In such case also have a look here.

Um die Werkeinstellung wiederherzustellen muss man sich im Setupmenü befinden! Das heißt es muss mindestens die LED bei Punkt A dauerhaft leuchten und man darf den Taster nicht mehr betätigen. Erst dann kann man durch Drücken und langes Festhalten des Tasters den Reset ausführen.

Bedenken Sie, dass der Reset nur die Daten von Parameter und Setupmenü auf die Grundeinstellung zurücksetzt. Sollte das Microbeast z.B. wegen falscher Empfängereinstellung nicht starten oder aus anderen Gründen nicht (mehr) starten, so ist ein Reset nicht hilfreich. Daher lässt sich der Reset auch nur im Menü selbst aufrufen und nicht an anderer Stelle. Sollte ein solches Problem vorliegen beachten Sie bitte [[Help:FAQ/de#MICROBEAST_does_not_finish_initialization._What_can_I_do.3F|diese]] Hinweise.

''Ich finde kein passendes Servohorn, dass sich exakt im 90 Grad Winkel zum Heckrohr aufstecken lässt. Microbeast/Trajectory/Ar7200BX hat offenbar keine Trimmfunktion!? Darf man über den Sender trimmen?''

Do not trim the rudder servo by using the transmitter as this will apply a constant rotation command to the unit! When you can't get the servo horn exactly 90 degrees this has no significant effect. The "90 degrees rule" only should give some good basis for initial linkage adjustment. In flight the system will control the servo all the time anyway, so it is not an issue if the center position is slightly offset.

Nein, trimmen Sie auf keinen Fall über den Sender. Dies würde einen ständigen Steuerbefehl und damit eine konstante Drehung verursachen, beeinflusst jedoch nicht direkt die Servoposition. Wenn das Servohorn nicht genau im 90 Grad Winkel aufgesteckt werden kann, so ist dies nicht weiter problematisch, da das System im Flug sowieso ständig Korrekturen ausführt. Wichtig ist, dass der Heli generell mechanisch korrekt abgestimmt ist: in der Mittenposition des Servos sollten am Heckrotor ca. 6 Grad Anstellwinkel gegen das Drehmoment anliegen. Bei Servovollausschlag in Richtung gegen das Drehmoment sollten 40 Grad Pitchwinkel am Heckrotor anliegen, in Steuerrichtung mit dem Hauptrotordrehmoment sollten ca. 20 Grad anliegen.

It is more important, that the tail servo linkage is in general adjusted correctly, so that you get asymmetric tail pitch throw: 40 degrees against main rotor torque direction, approx. 6 degrees at center position and 20 degrees in main rotor torque direction.

Please check whether everything works properly on the ground. When giving collective pitch input the swash should move up and down properly. When giving cyclic input it should return to zero after a few seconds. This is also especially after turning on Idle up or switching between flight conditions in the transmitter. Make sure that there are no trims, mixers, etc. in any flight condition and also make sure that the sensor directions for aileron and elevator are setup correctly (Setup menu point M)!

When taking off do not use too much cyclic input. Just let the motor come up to speed and then quickly give pitch input. Only when the helicopter is airborne the system can operate and control commands. If the helicopter sits on the ground, however, a stick input(= command to rotate the heli) would have no effect and the system would increase the cyclic pitch more and more desperately to perform a rotational movement. As soon as the helicopter will get "light" by increasing the collective pitch it will tip over abruptly. So always make sure that the swash is aligned straight during starting procedure!

* Beim Abheben so wenig wie möglich, am besten gar nicht, steuern. Einfach Motor hochlaufen lassen und dann zügig Pitch geben. Erst wenn der Heli in der Luft ist, kann die Regelung arbeiten und Steuerbefehle ausführen. Steht der Heli hingegen am Boden bliebe ein Steuerbefehl wirkungslos und das Regelsystem würde durch immer weiteres Erhöhen des Steuerausschlags krampfhaft versuchen, eine Drehbewegung auszuführen. Sobald dann der Heli durch Erhöhen des kollektiven Pitch "leicht" wird, fällt er schlagartig um. Also unbedingt vor und während des Startvorganges auf gerade Ausrichtung der Taumelscheibe achten.

Tilting in flight: Remove the main rotor blades and let the helicopter run in all speeds on the ground (beware of the rotating parts!). Again the swash should move straight up and down when giving pitch inputs. If at a certain speed it starts to tilt in one direction and this will depend on the rotor speed then that is almost certainly a vibration problem which confuses the sensors in the Microbeast. Trying different adhesive pads might help (smoother or firmer mount) or installing the unit in another location. But especially in the electric helicopter that brings in most cases nothing and there certainly is an error somewhere on the helicopter.

(Please do not confuse: A slight tilt of the swash plate when the heli is standing on the ground is absolutely normal when the so-called integrators are not fully discharged. This only will happen after approx. 30 seconds without moving the helicopter or touching the sticks, then the swash returns to its normal position. This also depends on the position of the throttle stick - in the middle position is the discharge at the fastest. A bug in the above named manner is present when the swash moves downright by itself to full-stop also after correcting with the sticks and only cycling power off and on can resolve this problem.)

===How can I increase rotation rate for aileron, elevator and rudder?===

===Der Heli rollt nicht schnell genug über die zyklischen Drehachsen. Kann man dies verbessern?===

The roation speed is only determined by the length of the stick signal (and especially has nothing to do with your cyclic pitch adjustment at setup points J or L and also has nothing to do with the cyclic pitch when steering cyclic on the ground!). So increasing/decreasing the stick throw, mostly done by increasing/decreasing servo throw or using Dualrate in the TX for the specified function, will increase/decrease roation rate.

===My servos are getting warm/hot, is this normal?===

===Warum werden die Servos wärmer als vorher beim Betrieb mit Paddelrotorkopf?===

Similar to a tail gyro a flybarless system is constantly working and correcting. So the servos are moving much more frequently than if ther are controlled manually. Additionaly to that the servos are usually driven with higher frequency to enable the system giving commands to the servos as often and quick as possible. And because of the abolition of mixing levers and the support of the auxiliary rotor plane the servos have to resist higher forces in flight.

Da bei einem Flybarlesssystem ähnlich wie bei einem Heckkreisel das Regelsystem andauernd am steuern und korrigieren ist, werden die Servos wesentlich häufiger bewegt als wie wenn Sie manuell angesteuert werden. Hinzu kommt die oft höhere Servoansteuerfrequenz die es der Regelung ermöglichen soll möglichst häufig Steuerkommandos an die Servos abzugeben. Zudem müssen die Servos aufgrund des Wegfalls der zahlreichen Mischhebel und der Unterstützung durch die Hilfrotorebene wesentlich höhere Kräfte im Flug aufbringen.

This results to a higher power consumption and a stronger heat generation which is usually not critical. However under adverse conditions this can reach a critical range (e.g. at very high air temperatures or even if the servos are installed near other heat sources such as electric motors). In this case try reducing the driving frequency and/or the input voltage.

Dies führt neben einem höheren Stromverbrauch auch zu einer stärkeren Wärmeentwickling der Servos die im Normalfall unkritisch ist. Allerdings kann diese Erwärmung unter ungünstigen Bedingungen auch in einen kritischen Bereich kommen z.B. bei sehr hohen Lufttemperaturen oder auch wenn die Servos in der Nähe von anderen Hitzequellen wie Elektromotoren verbaut sind.

Abhilfe schaffen eine Reduzierung der Ansteuerfrequenz sowie Reduzierung der Eingangsspannung. Dies führt allerdings immer auch zu einem schlechteren Wirkungsgrad der Regelung!
