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 started in the first flight mode, you can spool up the rotor by applying throttle manually and hover the helicopter. With the second flight mode the throttle curve is switched to a „V“-shaped curve and simultaneously the RPM Governor is turned by the auxiliary channel. In this case pay special attention that the two throttle curves overlap as good as possible in the point at which the transfer between the two flight modes takes place. 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 the get go and let the rotor spool up autonomously. If you want this, you must activate the RPM Governor before switching to your second flight mode!

==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 [[Manuals:MB_Plus:Governormenu_D|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.<br />

When you see the rpm view, the Status LED will be <b>off</b>. After some time without any change, the display switches back to show the tail gyro status (Status LED <b style="color: blue;">blue</b> or <b style="color: purple;">purple</b>).<br />

==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!
