===Nitro===
===Nitro Governor with separate Governor control channel===
In '''nitro''' mode the throttle servo can be controlled entirely via the throttle channel of the remote control as long as the RPM Governor is switched off. Only when the RPM Governor is switched on, this will control the throttle servo to spool up the rotor to the desired speed (if this is not yet reached) and ensure that the rotor speed is maintained during the flight. The manual throttle control is especially necessary to start and warm up the engine as well as to stop the engine after flight. Also some model engines react very sensitive in the lower throttle sector and too abrupt engagement can cause the engine to quit, i.e. when the clutch is not fully engaged and/or the rotor is not yet turning. In this case a manual throttle control can be of advantage as the pilot can run the engine to speed by hand before control is passed over to the RPM Governor.<br />

If a separate control channel is used for the RPM Governor the throttle servo can be controlled as usual via throttle channel and throttle curves of the transmitter. By switching the separate control channel in different positions, the RPM Governor can be activated and the desired rotor rpm can be preset. Note that for safety reason the throttle channel has priority over the RPM Governor when the output is below 25%. So you can always control the lower throttle servo positions by hand, even if the RPM Governor is already switched on. Then when the throttle is raised above 25% the RPM Governor intervenes and spools up the rotor. Also when you want to bring the throttle servo to idle position for autorotation or to shut off the engine you can always do this, regardsless of how the RPM Governor is switched. Anyhow keep in mind that MICROBEAST PLUS will be set to autorotation bail out mode if the RPM Governor is switched on and the throttle channel is brought below 25%. When throttle then is increased again, the RPM Governor will speed up the rotor faster than on initial spool up! Therefore if you make a stopover and the rotor is completely stopped, the RPM Governor must be completely disabled once by using the separate control channel. So the RPM Governor is reset and will perform an initial startup again. Otherwise if autorotation mode would still be active, the helicopter may tip over due to the abrupt speed up (this does not apply if you set the bail out spool up rate at [[Manuals:MB_Plus:Parametermenu_K/en|Parameter menu point '''K''']] as high as the initial spool up rate).<br />

===Nitro Governor - Simple mode===
If no separate control channel is used for the RPM Governor, throttle servo and RPM Governor are solely controlled by the throttle channel. For this purpose the control range of the throttle channel is divided into two parts: Below the center position, the throttle servo is controlled manually by the throttle channel. The RPM Governor is switched off and the servo output range is doubled, so that the throttle servo can be moved over the entire range. Once the throttle channel is moved (switched) to the upper area, the RPM Governor will activate, spool up the rotor and try to hold the preset rpm. Similar as it was described above for electric models you make the throttle curve a horizontal line, so that regardless of the position of the throttle stick MICROBEAST PLUS will always see the same throttle value and so the preset rpm will stays the same. So at least two flight phases are necessary. One that the throttle curve goes only up to the middle and in which the motor can be controlled by hand, i.e. for starting the motor and one flight phase that activates the RPM Governor and the throttle curve is used to preset the desired rotor head speed.<br />
