The 2D Mode Tab
1.
Controls the 2D Heading Hold gain. When set above zero, this option determines how hard the Guardian will assert a roll to k
Heading. 0: Off; 1: Low; 10: High. See: 2D Heading Hold Gain

Controls the Automatic Turn Coordination gain. In 2D Mode, this
feature will automatically coordinate your turns for you.
0: Off; 1: Low; 10: High. See: Automatic Turn Coordination

Stabilization Pitch/Roll Angle: The maximum target Pitch/Roll
angles that the Guardian will allow your model to assert. This will
be approximate as stabilization gains can affect this behavior.

The 3D Mode Tab

See: Enable 3D Heading Hold
2.
See: Direct Rate 3D Control

When Direct Rate 3D Control is enabled, this sets the angular rate
in rotations per second for each axis that the Guardian will attempt
to get your airframe to assert at full control stick deflection.

The Servo Config Tab
1.
See: Expanded / Custom Servo Ranges
2.
If Expanded / Custom Servo Ranges is enabled, these fields allow
an advanced user to specify hard limits to the Guardian’s outputs.
Useful for custom setups that will be damaged by servo deflection
beyond certain angles. Normal servo deflection pulse length ranges (+/
100%) are 1100 us to 1900 us. +/- 150% servo deflection ranges are
900us to 2100us.
The Advanced Tab
1.
Controls the pulse frequency from the outputs of the Guardian.
Useful for digital servos.

Troubleshooting / F.A.Q.
Question: Is it OK to use expanded rates / ranges on my transmitter?
Answer: While using expanded servo ranges on your controller will not cause
problems, they are not needed and may cause confusion. The Guardian will
use its own expanded ranges depending on your gains, and any Custom Servo
Ranges that may be defined through the PC App. In both 2D and 3D Modes,
higher gains will result in an improved responsiveness. In 3D Mode, activating
Direct Rate 3D Control and increasing the Direct Rate Speed for a given axis
will cause the model to rotate more quickly around that axis. In this way, the
Guardian 2D / 3D Stabilizer makes user-defined Dual (Expanded) Servo Rates
unnecessary.
Reduced Servo Rates / Ranges: In 2D Mode, full stick deflection will

Expanded Servo Rates / Ranges: 2D Mode may not be able to prevent inverted maneuvers, e
proportionally faster Pitch/Roll/Yaw rates.
Issue: The Guardian does not move my servos when I move the model around.
Solutions:
•
Make sure that the gain control knobs on the Guardian are not in the center (vertical) position, which disables stabilization
•
If you are using a 3 position Mode/Config switch, make sure it is not set in the center (disabled) position.
•
If you are using a Gain knob on your transmitter, make sure that it’s not turned to
Issue: The Guardian moves my servos in the wrong direction as I move the model around.
Solution: The gain control knobs on the Guardian set the direction of stabilized servo movement, as well as the gain level.
