==Electric Governor==
In '''electric''' governor mode the pilot does no longer control the speed controller with the transmitter. The AR7210BX completely takes over control of the ESC. With the transmitter you only specifiy the desired rotor speed you want the helicopter to maintain. When setting a speed higher than minimum, the AR7210BX will speed up the rotor smoothly and ensure that the demanded rotor speed is kept constant throughout the flight. To practice autorotation landings, additionaly you can hold the AR7210BX in a special mode that causes the speed controller to be switched off during the maneuver but speed up the rotor fast when aborting the autorotation (faster than with the initial soft start).<br />
<br />
The rotor speed is set via the throttle channel of the transmitter. You may use the transmitter's throttle curves for instance, so you can switch the motor on and off and pretend different speeds using the flight mode system of the transmitter. Instead of curves you have to set horizontal lines so that the channel output value does not depend on the throttle stick position but is fixed in each flight mode. The flight mode switch then acts as a switch that switches between different speed settings. Alternatively, of course you may use a switch that is directly assigned to the throttle channel and adjust the switch position to preset different rotor speeds and to switch off the motor, but this may be much less convenient.<br />

<br />
In '''electric''' mode the adjustable throttle range is 4200rpm/min. The lowest rotor speed that can be set is 800rpm/min, the maximum speed is 5000rpm/min. To enable autorotation bail out mode the throttle must be set to a value between 5% and 15%.<br />
