Global Variables for Color Screen Remote Controller
Global variables are variables whose values are shared across all configuration screens of the model. Their values can be used for weights, offsets, differential, exponential settings, outputs, and logical switch comparisons. The Global Variables screen in the model settings displays the value of each global variable for each flight mode.
Global Variables Screen:

Selecting a global variable from the Global Variables screen provides the following options:
- Edit - Opens the Global Variable configuration screen for the selected global variable.
- Clear - Clears the global variable values for all flight modes of the selected global variable.
Global Variable Configuration Screen:

The Global Variable configuration screen is where you assign values and other configuration options to a global variable. Additionally, you can choose how to define the global variable value for each flight mode - either by manually defining the value or inheriting from another selected flight mode. It contains the following configuration options:
Name - The name of the global variable. Allows three characters. If left empty, GV# will be used as the name by default.
Unit - (Optional) Allows you to add a % label to the displayed value when selected. It does not affect how the value is calculated.
Precision - Allows you to select a numeric precision option, integer (0.-) or decimal (0.0). Default value is 0.-
Minimum - Defines the minimum value allowed for the global variable.
Maximum - Defines the maximum value allowed for the global variable.
Popup - When enabled, a popup message will be displayed when the GV value changes to a new GV value (see below).
FM0- Global variable value on Flight Mode 0.FM1 → FM8 - When the toggle switch is enabled or disabled, the following applies:
- Toggle switch disabled - The global variable value for the selected flight mode is inherited from the flight mode defined in the dropdown menu.
- Toggle switch enabled (highlighted) - The global variable value for the selected flight mode is manually defined in the text field.
