Guardian configuration page software reference – Eagle Tree Guardian 2D/3D Stabilizer User Manual

Page 12

If you have other Eagle Tree products (such as the eLogger, OSD Pro, or Seagull) the main software screen will continue to appear, just as it does now. To launch the
Guardian Stabilization configuration page, just click “Hardware, Configure
Guardian 2D/3D Stabilizer”.

Guardian Configuration Page Software Reference

The General Tab

Artificial Horizon Indicator (AHI): Displays the measured Pitch/Roll of
the Guardian relative to level (when in 2D mode) or when in 3D Mode,
relative to the last locked 3D Heading. Note: since 3D mode results in
the AHI showing level related to the last locked 3D heading, it will NOT
display true level when your model is sitting level. Switch to 2D mode
if you want the AHI to display true level.

Indicators for the positions of the dials on the Guardian (2b) and the last
recorded positions as loaded from a saved file (2a). When loading a
saved configuration file, you can use the two displays to match your
previous dial configurations with your current setup, allowing you to
easily replicate the saved profile.

Reset Neutral Servo Deflections: When pressed, this will record the current servo signals coming into the Guardian from your receiver. If no receiver is
connected and powered at this time, then the zero servo deflection of
1.5ms pulse length will be used as the failsafe value for each
disconnected channel except for Gain and Mode, which will failsafe to
approximately 40% gain and the currently selected Default Flight Mode.

Reset Level Pitch/Roll: Will record the orientation of the Guardian
relative to level to compensate for mounting offsets. This step will fail
if either the Pitch or Roll is greater than 25 degrees.

10. Save Configuration: Records your current settings as set on the

Guardian to a .txt file to load later. Useful for saving profiles for
individual airplanes.

11. Load Configuration: Recovers the settings from a previously saved

configuration file and writes them to the connected Guardian.

12. Factory Reset: Restores the connected Guardian unit to its factory

default settings.

13. Firmware Update: Loads the Firmware Control dialog.

14. Level Pitch Trim: Adjust this value to fine tune the level flight

orientation in the pitch axis.

15. Level Roll Trim: Adjust this value to fine tune the level flight

orientation in the roll axis.

16. Rezero Gyros: Zeroes the gyroscopes inside the Guardian. Under some

circumstances, this can help improve leveling accuracy after extended
maneuvering in the air.

The 2D Mode Tab

Controls the 2D Heading Hold gain. When set above zero, this option determines how hard the Guardian will assert a roll to keep the airframe on its locked 2D
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.

See: Center Stick Stabilization Only Mode

See: Center Stick Box Size

The 3D Mode Tab

See: Enable 3D Heading Hold

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.

See: Derivative Gain

The Servo Config Tab

See: Expanded / Custom Servo Ranges

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.

Controls the pulse frequency from the outputs of the Guardian. Useful for digital servos.
