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.
A third flight mode is used for auto-rotation: Here the throttle channel is constantly set to a value close below center position (between 40% and 50%) . When you switch to this flight mode once the governor was active, the throttle servo will be moved to the idle position set at menu point B. When switching back to governor mode, i.e. when you want to bail out from autorotation, the rotor will be spooled up at an increased rate (this does not apply if you set the bail out spool up rate at Parameter menu point K as high as the initial spool up rate - see chapter 8). Alternatively if it is switch back to the flight phase with manual control, autorotation mode is canceled and the next time you switch on the RPM Governor, the rotor is spooled up slowly.
