Line 35: − + − Nitro helicopters react very sluggish during rpm rampup. Especially when the clutch is worn out it can take a lot of time until the rotor gains full head speed while the motor already runs at full speed, trying to spool up the rotor. This will cause the RPM Governor to stay at full speed as it detects the desired rpm seems to be faster than the helicopter allows. So you need to prevent the throttle from opening completely during spool up by decreasing the Governor quick change rate (Parameter menu point K) to a value that represents the maximum speed the helicopter is able to ramp up the throttle.<br />+ − + − + − +

==Can I use the governor in combination with a standard (multi-wire) receiver? Why not?==
The governor can only work in combination with a serial line receiver. This is for technical reason:
* when using a multi-wire receiver all ports on MICROBEAST PLUS are occupied already. There is no free port left to connect the motor speed sensor.
* also there is no free port for the throttle output where the ESC must be connected to
* in addition to control the governor we need the throttle channel (or other type of channel) from the radio. But with a multi-wire receiver we only have the 5 channels for roll, pitch, rudder, ... there is no throttle/additional aux channel.<br />
<br />
So in summary with the Standard receiver layout we would need at least 3 additional ports on the Microbeast which are not there, unfortunately. Reasons are that governor function was implemented after MICROBEAST PLUS was designed, but also it would make the device much bigger and more complicated when adding 3 additional ports. The benefit of making MICROBEAST PLUS bigger would be little, as today most radio brands offer some sort of serial wire receiver. And serial wire is the way to go in our opinion, as it offers much more options and flexibility in general.<br />

==Nitro RPM Governor - When recovering from an autorotation using the autorotation bail out function the throttle increases up to nearly full throttle and stays there==
==Drehzahlregler (Verbrenner) - Der Motor scheint fast mit Vollgas zu laufen nach Abbruch einer Autorotation==
Verbrennermodelle reagieren sehr träge beim Hochfahren der Drehzahl. Vor allem wenn die Kupplung nicht mehr gut greift, kann es sehr lange dauern, bis die volle Motorkraft auf den Rotor übertragen wird. Wenn man zu schnell Gas gibt kann es passieren, dass die Drossel voll geöffnet wird, obwohl der Motor noch lange nicht mit der gewünschten Drehzahl läuft. MICROBEAST PLUS geht in diesem Fall davon aus, dass die gewünschte Drehzahl nicht erreicht werden kann und legt sich auf den erreichten Gasbereich fest. Um dies zu verhindern, müssen Sie die Änderungsgeschwindigkeit ([[Manuals:MB_Plus:Parametermenu_K/de|Parametermenü Einstellpunkt '''K''']]) reduzieren, so dass die Geschwindigkeit den mechanischen Gegebenheiten entspricht. Dabei ist es durchaus denkbar, dass diese nicht höher eingestellt werden kann, als die Geschwindigkeit für den initialien Sanftanlauf ([[Manuals:MB_Plus:Parametermenu_J/de|Parametermenü Einstellpunkt J]]).<br />

==How to adjust Parameter menu point I (RPM Governor - Throttle response)==
==How to adjust Parameter menu point I (Governor - Throttle response)==
Use menu point I to change the response of the RPM Governor. This determines how fast and hard the system will open or close the throttle when the rotor rpm changes. With ideal throttle response you get a very consistent rotor head speed - the head speed should recover quickly and definite but not hectic when loading and unloading the rotor head.

* If throttle response is too low the main rotor may speed up immediately in unloaded conditions, e.g. when the helicopter is descending and the RPM Governor will only give soft throttle inputs when the head speed decreases.
* If throttle response is too low the main rotor may speed up immediately in unloaded conditions, e.g. when the helicopter is descending and the governor will only give soft throttle inputs when the head speed decreases.
* If the response is set too high on the other hand, the throttle may stutter audible when unloading the motor and/or the motor rpm will kick in very hard and overshoot after the rotor head was loaded and the rpm decreased, causing the tail rotor to turn due to the immediate load change.

The height of throttle response highly depends on factors such as heli size (blade size), motor power and performance and/or the throttle response behavior of the speed controller (when flying an electric heli). If you need to adjust the throttle response, we recommend to start with the lowest value and increase accordingly. Also you should use a lower head speed for adjustment as here you can see the effect more distinct.<br />

{{QUOTE|Only increase the throttle response stepwise and make sure the throttle will not start to oscillate. Note that with nitro helicopters high throttle response can cause the motor to quit when the throttle is opened too fast. With electric helicopters changing the throttle very fast can cause the speed controller to overheat and especially hard changes from unloaded to loaded conditions can cause incorrect commutations of the ESC (depending on the type of motor) which can damage the ESC if this does not have appropriate protection mechanisms.}}<br />
