Fliegen mit dem MICROBEAST PLUS Drehzahlregler (optional)
Die Drehzahlreglerfunktion ist ein optionales Feature und ist nicht in allen MICROBEAST PLUS Firmwareversionen enthalten! Ausserdem kann diese Funktion nur in Kombination mit SingleLine-Empfängern verwendet werden.
Die Drehzahlregelung kann generell erst eingeschaltet werden, wenn MICROBEAST PLUS betriebsbereit ist. Während der Initialisierungsphase wird das Gassteuersignal vom Sender direkt an das Gasservo weitergegeben. Achten Sie daher (vor allem bei Elektromodellen) beim Einschalten und während der Initialisierungsphase unbedingt darauf, dass der Gaskanal auf „Motor aus“ Position steht (und nicht auf "Autorotation")!
Seit Firmwareversion 4.1.x muss der Motorkanal grundsätzlich nach dem Einschalten auf die Failsafeposition oder darunter gestellt werden, wenn der Drehzahlregler verwendet wird. Erst dann wird der Gaskanal freigegeben. Falls es erforderlich ist, dass beim Einschalten Gas gegeben werden kann, z.B. um einen Motorsteller zu programmieren, dann muss der Drehzahlregler über bei Setupmenü Einstellpunkt N vorübergehend deaktiviert werden.
As described above at Governor menu point D set your throttle curves or the auxiliary channel in the various flight modes as high as necessary, so that the desired head speed will be approached and observed. Keep in mind that the head speed should not be higher than 80% of the maximum head speed that is possible with this motor and this gear ratio. If the chosen head speed is too high, the RPM Governor will constantly give full throttle input and no effective govering will be possible because there is not enough room left to open the throttle for compensating the rotor head load.
RPM Display
Since Firmware Version 4.2.x there is an integrated rpm display that shows the height of preset rotor speed when in operation mode. This can be used to additionally check your transmitter setup over Governor menu point D, i.e. when the heli is standing on the workbench with motor disconnected or removed rotor blades (Caution: Be very careful and keep a safe distance when running the model on the work bench for testing purpose!). Using the electric governor function with soft start feature, also you will see the actually measured rotor speed as soon as the ramp up starts and the rotor speed gets higher than 600rpm.

When you see the rpm view, the Status LED will be off. After some time without any change, the display switches back to show the tail gyro status (Status LED blue or purple).
Note for using the nitro governor with separate switch channel
Some transmitters offer a special setting that allows to automatically switch the auxiliary governor channel together with the flight mode switch. So the motor can be ignited in the first flight mode and you can spool up the rotor and hover the heli by applying throttle manually. With the second flight mode the throttle curve is a "V"-shaped curve and simultaneously the RPM Governor is turned on by the auxiliary channel. In this case pay special attention that the two throttle curves/throttle positions match as good as possible in the stick point at which you usally switch flight modes. Otherwise the throttle servo would make a jump before the RPM Governor will take over control as you still may be in manual mode for a short amount of time. So in this type of operation it is not possible to activate the RPM governor from idle position and let the rotor spool up autonomously. If you want this, you must activate the RPM Governor before switching to your second flight mode with an additional switch!
