control stick from its centered position. Once the stick is moved past a certain point, controlled by this setting, stabilization is fully
disabled. (2D Mode Only)
Radio Stick Menu Options: 1-10: Center Stick Box Width
4. Automatic Turn Coordination
Employs the “Step On The Ball” method to move the Rudder in order to coordinate your turns in 2D Mode. All you need to do is roll
your plane and the Guardian will take care of the Rudder to coordinate your turn. (2D Mode Only)
Note: When taxiing in 2D Mode on an incline, this feature will try to yaw your model down the hill.
Note: If the Guardian is not very close to the center of gravity, then this feature can increase the chance of Yaw oscillations.
Radio Stick Menu Options: 1: Off; 2: Low; 10: High
5. 2D Heading Hold Gain
When the control stick is centered horizontally (zero Roll command) in 2D Mode, the controller will roll the plane to track its current
heading. (2D Mode Only)
Radio Stick Menu Options: 1: Off; 2: Low; 10: High
6. Direct Rate 3D Control
When in 3D Mode, the plane will react much more precisely with this feature enabled. Instead of simply stabilizing the 3D flight, it will
control the rotational rates of the plane directly. This provides very strong disturbance (wind, airframe inertia, etc) rejection without
having to “fight the gyro”. (3D Mode Only)
Note: This feature will expand your servo deflections beyond any limits set on your transmitter, up to the limits set by the Guardian.
See Expanded / Custom Servo Ranges for more details on how to limit servo deflections.
Radio Stick Menu Options: 1: Off; 2: On
7. Enable 3D Heading Hold
Enables the 3D Heading Hold feature in 3D Mode. Those looking for the stability and precision of the Guardian without anything else
getting between them and their airplane can disable this feature for a rate-gyro experience. (3D Mode Only)
Note: Direct Rate 3D Stabilization is strongly recommended if this mode is set to “Off”.
Radio Stick Menu Options: 1: On; 2: Off
8. Derivative Gain
Tunes the dampening/derivative gain of the airplane. Increasing this value will strengthen the “rate gyro” behavior of the Guardian
while leaving the 2D leveling and 3D Heading Hold behaviors the same.
Note: Increasing this value without reducing your overall or individual axis gains will increase the chance of oscillations.
Radio Stick Menu Options: 1: Low Derivative; 10: High Derivative
9. Onboard Dual Aileron Mixing Enabled
Configures the Guardian to accept unmixed Aileron and Flap (Aux In) inputs and mixes them internally to provide Dual Aileron /
Flaperon outputs on Ail and Aux Out. If disabled, the Guardian will accept premixed Flaperon signals. Useful with limited controllers
that cannot perform Flaperon mixing. Disabled by default.
Radio Stick Menu Options: 1: Off; 2: On
10. Aux Servo Output Reversed
Reverses the direction that stabilization will move your second Aileron servo if you are using the Aux channel in a Dual Aileron
configuration.
Radio Stick Menu Options: 1: Off; 2: On
11. 2
nd
Elevon Reversed
Set this if the second Elevon servo on a “Delta” wing plane is not symmetrically mounted and is resulting in incorrect servo movements.
Radio Stick Menu Options: 1: Off; 2: On
12. Expanded / Custom Servo Ranges
Allows advanced users to expand the functional range of their servos from 125% around their trim values to 150% around their trim
values. Overall servo deflection range is expanded to 175%, including trims. When configured on the PC software, this option also
enables custom servo limits that can be set there.
Note: This can damage your servos and your plane if activated carelessly. It was included for advanced modelers that needed the
extra range or wished to apply custom ranges to their servos. Make sure to reset your trims before activating this mode!
Radio Stick Menu Options: 1: Off; 2: On
13. Default Flight Mode (For when Mode/Config switch is unused/disconnected)
If you don’t have the Mode input channel connected during flight, the Guardian will use the flight mode selected here. Note that you will
need to set this with the PC Software, or temporarily connect a switch to the Mode input channel to set it.
Radio Stick Menu Options: 1: 2D Mode (default); 2: 3D Mode
