Mode/Config Switch Behavior

The Mode/Config input on the Guardian lets you change your stabilization mode in-flight between 2D

Mode, 3D Mode and Disabled (if a 3 position switch is used). Additionally, you can configure the

Guardian in the field via a series of toggles of the Mode/Config switch (within 15 seconds of Guardian

power up), referred to as “Configuration Gestures”.

Leaving the Mode/Config input disconnected will cause the Guardian to switch to the Default Flight

Mode. The factory default of this setting is “2D Mode.” If you want to use a different mode in this

case, you will need to use the PC software to set the mode, or temporarily connect the Mode/Config

input to change the mode via the radio stick configuration. See the Default Flight Mode menu item in

the List of Features and Options section below.

Flight Mode Selection

Please refer to Figure 9. The Guardian has three main operating modes (described earlier) that can be set by the Mode/Config switch

position:

• Down: ( Position 2 , -100%, 1.1ms): 2D Stabilization Mode:

• Middle: (Position 1, 0%, 1.5ms, only available if you are using a 3 position switch): None – No stabilization or damping. All

servo signals are directly passed through. (Elevon and V-Tail mixing is still performed)

• Up: ( Position 0, +100%, 1.9ms): 3D Stabilization Mode

Configuration Gestures

Within 15 seconds after Guardian power-on, the Guardian can be configured by toggling the Mode/Config switch back and forth rapidly.

The number of times you toggle the switch determines which configuration step is performed. Note that if you have a 3 position switch,

its center position is not used during toggling. Here is a table of available configuration gestures, and what each does.

Reset Level Flight and Trims: 1 Toggle (up-down if the switch is presently down, or down-up if presently up)

After changing the trims on your controller or mounting orientation, you must let the Guardian know about this change so it can best

control your airplane. Without this information, 3D Heading Lock will not work and stabilization performance will be degraded.

To update the trim and level flight information for your controller in the Guardian, quickly toggle the Mode Switch back and forth once

within the first 15 seconds after power-on. You will know that the level flight orientation and trims have been reset when the servos both

twitch once and then immediately return to normal movement.

If no twitch occurs when executing Reset Level Flight and Trims, it can either be because the switch gesture was not done quickly enough

or within the first 15 seconds following boot. Alternatively, if the Guardian is mounted too far off of level flight (greater than 25 degrees

in either Pitch or Roll), the Reset Level Flight and Trims will fail, presenting no servo twitch.

Reset Trims Only: 2 Toggles (up-down-up-down if the switch is presently down, or down-up-down-up if presently up)

Use this gesture to reset your trims without needing to also reset your level flight orientation.

To quickly update the trims of your plane in the Guardian, quickly toggle the Mode Switch back and forth two times within the first 15

seconds following power-on. (Example: up-down- up-down) You will know that the trims have been reset when the servos both slowly

twitch twice and then immediately return to normal movement.

Toggle Elevon Mixing: 3 Toggles (up-down-up-down-up-down if the switch is presently down, or down-up-down-up-down-up if

presently up)

A shortcut method for switching between normal and elevon mixed airframes.

To quickly switch elevon mixing on and off without needing to go into the Radio Stick Menu or use the PC software, quickly toggle the

Mode Switch back and forth three times within the first 15 seconds after power-on. You will know that the trims have been reset when

the servos both slowly twitch three times and then immediately return to

normal movement. After this, moving your control sticks will reflect the

current mixing configuration.

This action will toggle from Normal or V-Tail Mode to Elevon Mode and

from Elevon Mode to Normal Mode.

Enter Radio Control Stick Menu: 4 Toggles (up-down-up-down-up-down-

up-down if the switch is presently down, or down-up-down-up-down-up-

down-up if presently up).

Enters menu mode (described below).
