EdgeTX provides 3 timers that can be custom programmed. Below are the configuration options.

Name: Name of the timer

Mode:

• OFF- The timer is not used

• ON - The timer runs all the time

• Start -The timer starts once the configured switch is activated. After the time is started, the timer ignores the switch position.

• Throttle - The timer starts once the throttle is raised and the configured switch is activated. The timer will stop counting if either the throttle position is lowered back to the minimum value or the configured switch is deactivated.

• Throttle % - The timer counts proportionally to the throttle. It counts in real time at full throttle and at half speed at 50% throttle.

• Throttle Start - The timer starts once the throttle is raised and the configured switch is activated. After starting, the timer ignores the throttle position and will keep counting unless the switch is deactivated.

Switch- Select the switch that will trigger the timer to start. If no switch is selected, the timer will trigger based only on the configured mode. In addition to a switch, you can also select a trim, a telemetry source (triggered when telemetry data is received from that source), or physical activity (stick movement or button press) (labeled as ACT)

Start- The time used for the timer's advanced functions. The default value is 00:00 and when left as such, the timer operates like a stopwatch, counting upward until stopped. If a different time is entered in this box, then the additional Direction drop-down menu option will appear.

Direction - If set to Show Remaining, the counter will function like a countdown timer - counting down from the designated time to zero and then alerting the user. If set to Show Elapsed, the timer functions like an alarm, counting up from zero until the designated time and then alerting the user.

Minute Call - If selected, you will be notified every minute that passes as described in the Count Down option.

Count Down:

• Silent - No notification is given until the timer reaches zero. When it reaches zero, you will hear one beep.

• Beeps - The radio will beep every second starting at the time designated.

• Voice - The radio will count down by second starting at the time designated.

• Haptic -The radio will vibrate every second starting at the time designated.

• Beeps & Haptic - The radio will beep and vibrate every second starting at the time designated.

• Voice & Haptic - The radio will count down and vibrate by second starting at the time designated.

Persistent:

• Off - The timer value is reset when switching models or when the radio is turned off / on.

• Flight - The timer value is NOT reset when switching models or when radio is turned off / on. The timer value is only reset when the Reset flight option is selected in the Reset telemetry menu.

• Manual Reset - The timer value is reset only when it is individually selected to be reset (example: Reset timer1) in the Reset telemetry menu.

Whenever a new model is loaded, EdgeTX will conduct pre-flight checks based on the checks that are configured on this page. If any of the checks are failed, EdgeTX will give the user an audio and visual warning that must be acknowledged before using the model. The following preflight checks are configurable:

Display checklist - When this option is selected, the model notes file will be displayed when the model is loaded. A valid model notes file must be in the Models folder on the SD card. The model notes file must be a .txt file and must have the EXACT same name as the model it is for, for example: Mobula6.txt. The text in the file is up to the user.

Throttle state - When selected, the radio will check that the throttle is at the minimum range value for the configured throttle source in the menu.

Custom Position? - When this option is selected, a number box will be shown that can be configured with a user-defined value for the throttle state check.

Switches - The section displays all the switches that are configured on the radio and allows you to select which position is the correct position for the switch state check. Selecting the switch will cycle through the available switch positions or turn the check off for the switch completely. Yellow switches have the switch position check activated. White switches e de-activated.

Pots & Sliders- When activated, this option checks the position of the pots & sliders. There are three options - OFF, ON and AUTO. When ON or AUTO is selected from the drop-down menu, buttons for the available pots and sliders will appear.

• OFF - Pot and slider positions are not checked.

• ON - Positions are checked against manually configured pot and slider positions that are set to active (yellow). To manually set the check position, select ON from the drop-down menu, put the pots and sliders into the desired position, and activate them by selecting them (yellow).

• AUTO - Positions are checked for activated pots and sliders and compared to the last automatically saved position before the radio was turned off or the model was changed.

Center Beep - Allows you to turn on / off the center beep function for the individual sticks, pots, and sliders by selecting them (yellow).

EdgeTX has to possibility to select a specific source and trim for the model throttle and allows for the following configuration options:

Reverse: When enabled, this option reverses the output direction of the configured throttle channel.

Source: The source that will be used for the throttle.

Trim idle only: When enabled, the throttle trim will only affect the bottom portion of the throttle band.

Trim switch: The trim switch that will be used to trim the throttle. It is possible to substitute the throttle trim switch with the aileron, rudder, or elevator trim switches.

The Enabled Features section of Model Setup allows you to configure which tabs are visible in the selected model's radio setup and model settings area of EdgeTX. You can select the following options:

• Global - When selected, the tab will take the global value configured in the Enabled Features area in Radio Setup. The configured global value will display next to the option.

• On - When selected, this tab will be visible when this model is loaded.

• Off - When selected, this tab will not be visible when this model is loaded.

The Heli Setup page in Model Settings is an optional page that is available on custom-compiled versions of EdgeTX. The heli setup page is often used for collective pitch mixing (CCPM) used in flybared helicopters where the receiver directly controls the swashplate servos. Most flybarless helicopters do not need to configure this page. The outputs of the CCPM mixer are CYC1, CYC2, and CYC3, which need to be assigned to an output channel on the Mixes screen.

The heli setup page has the following configuration options:

• Swash Type - Swash type for your model. Options are 120, 120x, 140, and 90.

• Swash Ring - Set the swash ring limit only as needed. 1 = maximum limit -> 100 or 0 = no limit.

• Long. cyc. source - Select source input.

• Lateral cyc.source -Select source input.

• Coll. pitch source - Select source input.

• Weight - Percentage value of the stick travel to use.

The configuration settings for both the Internal and External RF pages work the same. The only difference is that the Internal RF section is for configuring the built-in module and the External RF section is for configuring an RF module in the external module bay.

The Internal / External RF modules are "active" for a model when the buttons are yellow and inactive when they are white.

Receiver number

The receiver number is a user-assigned number for a model that is sent to the receiver when bound. Each model must have a unique receiver number. However, models using different protocols may have the same receiver number without issues. EdgeTX will inform you when a receiver number is unique or if it is already being used with a text above the number field.

The Inputs screen of Model Settings is where you map your physical radio controls (for example: sticks, sliders, and pots) to a software input to be used by the radio. After the control has been mapped it is then possible to apply modifiers to the inputs such as a weight, offset or curve which will then be applied anywhere that input is used. Although it is possible to also assign switches as inputs, it is normally not needed as switch outputs seldomly need to be modified by a weight, offset or curve. By default, EdgeTX will automatically map your contoller sticks to Aileron, Elevator, Throttle, Rudder based on the default channel order defined in Radio Setup.

Selecting the + button will show you a list of available inputs that can be configured. After selecting an input, the input configuration page for that input will open. Selecting an existing input will give you the following options:

• Edit - opens the input configuration page for that input line.

• Insert before - Inserts a new input line before the selected input.

• Insert after- Inserts a new input line after the selected input.

• Copy - copies the selected input line.

• Move - selects the input line to be moved. The input is moved using one of the paste commands after a new line is selected (i.e. cut & paste).

• Delete - deletes the selected input line.

• Paste before - pastes the copied or moved input line before the selected input line.

• Paste after - pastes the copied or moved input line before the selected input line.

Input configuration page

The input configuration page allows you to edit the input configuation parameters. To the right of the configuration parameters, you can see a live graph that shows how your configuration options will affect the slope of the input.

• Input Name - Name for the input. Four character are possible.

• Line Name - Name of the individual line in the input. Multiple physical inputs can be mapped to one input by adding an additional input line under the input.

• Source - The physical control used for the input. In addition to physical controls, you can also specify MAX (always returns 100), cyclics, trim switches, channel values and more. Moving the physical control after the source has been selected will automatically map it to that input.

• Weight - Percentage value of the stick travel to use (often referred to as "rates").

• Offset - The value added to or subtracted from the input source.

• Switch - The switch that activates the input line. If no switches are defined then it is always active.

• Curve - Specifies the type of curve that will be used. The following curve options exist:

  • Diff - Multiplies only the range above or below the middle (0) by the specified %.

  • Expo -The input value is changed exponentially. Increasing the % will result with a gentle slope near the middle(0). Decreasing the % will result in a steep slope near the middle (0). With a % of 0, the slope will be linear.

  • Func -

• Verticle point values - Adjust the point values to make the desired curve.

The Outputs screen of Model Settings is where final adjustments to the control data are made (including subtrims, curves, endpoint, and center values) before finally sending the control data to the RF module. This is where the channel center, limits (to prevent servo binding) and output direction are set.

The output screen shows all the configured output channels. For each output line, it displays the values for the minimum and maximum limits, subtrim, center point, subtrim mode and channel monitor. The two options below are also available on the output page:

• Add all Trims to Subtrims - When selected, adds the current trim value to the subtrim value for each configured output. The trim value is then reset to zero.

• Extended Limits - When enabled, it increases the minimum and maximum range for the output values to -150 and 150. Extended limits are necessary if the full range of the control surface cannot be reached with standard limits.

Selecting an output line will give you the following options:

• Edit - Opens the output configuration screen.

• Reset - Sets the subtrim value back to zero. The trim value is not changed.

• Copy Sticks to Subtrim - Adds the current value of the stick deflection as the subtrim value.

• Copy Trims to Subtrim - Adds the current trim value to the subtrim value. The trim value is not changed.

The output configuration screen has the following configuration options:

• Name - Name for the Output up to 6 characters.

• Subtrim - The subtrim value (max 100). It can also be set to a global variable by pressing the "GV" button and then selecting the desire global variable from the dropdown menu.

• Min - Minimum output limit. Commonly used to prevent servo binding on models that use servos for the control surfaces.

• Max - Maximum output limit. Commonly used to prevent servo binding on models that use servos for the control surfaces.

• Inverted - Select this option if you want to invert the output value.

• PPM Center - Specify the pulse-width value for the center value of the output channel (between 1000 - 2000). Changing this will shift the entire output range, including upper and lower limits.

• Subtrim mode - Defines how the subtrim value affects the min/max output values. There are two options:

  • Center Only - Only the center value shifts and the upper and lower limits do not change. The reaction of the stick differs between the upper half and the lower half from midpoint.

  • Symmetrical - the upper and lower limits will shift according to the shift of the center value. The reaction of the stick is the same on both sides of the midpoint.

Telemetry is data received from the model to the radio from various sensors. These sensors may be in included in the radio receiver or flight controller, or may be separate sensors, such as GPS, variometer, or magnetometer. Telemetry data that is received can be displayed by EdgeTX in widgets, configured in alarms or audio call-outs.

Sensors

The following options are listed under the sensor list.

• Discover New: When selected, it will look for new sensors on the model and automatically configure them.

• Add New: When selected, it will create a new blank sensor for that must be configured manually.

• Delete All: This option will delete all prevously configured sensors. Note: This button will not be visible if there are no sensors configured.

• Show instance ID:

• Ignore Instances: This options prevents mutltiple sensors from reporting the same telemetry data.

If you select a specific sensor, you will get the following options:

• Edit: Allows you to edit the sensor's configuration options.

• Copy: Creates a copy of that sensor.

• Delete: Deletes that sensor.

Rx-Stats

Here you can configure the threshold for the RX alarms. The Rx-Stats label will change (Rx-Stats, RSSI, Rqly, Sgnl) depending on the protocol that is used with the model.

• Low alarm - The threshhold value when the "RF signal low" voice prompt will be played. The recommended value is 45.

• Critical alarm - The threshhold value when the "RF signal critical" voice prompt will be played. The recommended value is 42.

• Disable telemetry alarms - When enabled, no alarm voice prompts will be played.

Variometer

A variometer detects changes in the model altitude. EdgeTX can alert the user of these altitude changes by providing a rising/lower pitched tone. Use the Variometer menu on the Radio Setup page to set the actual frequency and volume of the tone to be played. The following options exist to configure the variometer alarm.

• Source - Specifies the sensor to use as the variometer. It is selected from the telemetry sensors added in Sensors section.

• Center - Specify the range for ignoring changes in climb/descent rates. When the climb/descent rate is within the range specified here, the beeping pitch will not change.

• Tone/Silent - Specifies whether to beep when climb/descent rate is within the range specified by Center.

Logical Switches are virtual two-position switches whose values (ON/OFF or +100/-100) are based on the evaluation (true/false) of a defined logical expression. Once configured, logical switches can be used anywhere in EdgeTX that a physical switch can be defined.

The Logical Switches page in Model Settings shows you all the configured logical switches as well as an overview of their configured options.

Selecting the + button will allow you to select an unused logical switch to configure.

Selecting a configured logic switch will give you the following options:

• Edit - Opens the Logical Switches configuration page for the selected logical switch.

• Copy - Copies the selected logical switch

• Paste - Pastes a copied logical switch onto the selected logical switch. Note: it will overwrite the selected logical switch.

• Clear - Deletes all configuration options for the selected logical switch.

After selecting to edit a logical switch, you will have the following configuration options:

• V1 - The first variable in the expression to evaluate.

• V2 -The second variable in the expression to evaluate.

• AND switch - Switch that must be active to allow the logical switch to be evaluated for activation.

• Duration - The duration that the logical switch will remain active (true) once meeting activation criteria. If set to 0.0, the the logical switch will remain active (true).

• Delay - Delay between when the activation criteria for the logical switch has been met and when the logical switch changes to the activated state (true).

Logical Switch Functions

In the expression, a and b represent sources (sticks, switches, etc.), and x represents the constants (values) to be compared.

The following sensors are commonly used and normal automatically detected by EdgeTX:

The Radio Settings section contains all the options to configure your radio. Across the top of the page you will see icons that will take you to different pages of radio settings when selected. The default screen for the radio settings is the Tools screen.

Icons at the top of the radio settings screen include (in order from left to right):

• Tools

• SD Card

• Radio Setup

• Themes

• Global Functions

• Trainer

• Hardware

• Version

Global variables are variables whose values are shared across all the configuration screens of a model. Their values can be used in weights, offsets, differential, expo settings, outputs, and in logical switch comparisons. The Global Variables screen of Model Settings shows the value of each global variable for each flight mode.

Selecting a global variable from the global variable screen will give you 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 for the selected global variable.

The global variable configuration screen is where you assign a value and other configuration options to a global variable. Additionally, you can select how the value of the global variable is defined for every flight mode - either the value is manually defined or inherited from another selected flight mode. It contains the following configuration options:

• Name - Name for the global variable. Three characters are allowed. If left blank, it will use the default GV# as the name.

• Unit - (optional) Allows you to add a % label to the displayed values when selected. It DOES NOT affect how the values are calculated.

• Precision - Allows you to select the number precision options whole numbers (0.-) and decimal (0.0). The default value is 0.-

• Min - Defines the minimum that is allowed for the global variable.

• Max - Defines the maximum value that is allowed for the global variable.

• FM0 - The value of the global variable on Flight Mode 0.

• FM1 -> FM8 - When the toggle switch is enabled or disabled, the following applies:

  • Toggle switch disabled - global variable value for the selected flight mode is inherited from the flight mode defined in the drop-down.

  • Toggle switch enabled (highlighted) - the global variable value for the selected flight mode is manually defined in the text field.

Flight modes allow you to have different trim settings for each flight mode. Once multiple flight modes are configured, you can adjust the trim settings in each flight mode without affecting the trim settings in other flight modes (unless they are configured to do so). There are 9 possible flight modes to use, with Flight Mode 0 being the default flight mode.

The Flight Mode screen displays an overview of each flight mode. The highlighed flight mode designates the active flight mode. Selecting a flight mode will take you to the configuration page for that flight mode.

Check FM Trims: When the check FM trims button is pressed, the trims for the current flight mode are temporarily disabled. This is used to test the impact of the current flight mode’s trims on the outputs.

The flight mode conifiguration screen has the following options:

Name: The custom name for the flight mode. If configured, this name will be shown on the lower center position of the main screen between the trims.

Switch: The trigger to enable that flight mode. It can be a switch, pot, telemetry, trim or logical switch.

Fade in: Gradually change the trim value when this flight mode is enabled. Specify the time in seconds (0.0 - 25.0) until the value change is completed.

Fade out: Gradually change the trim value when this flight mode is disabled. Specify the time in seconds (0.0 - 25.0) until the value change is completed.

Trims: To configure the trims, select the trim that you want to configure to make sure that it is turned on (yellow). Then select the flight mode (0-8) that will provide the initial trim value and modifier (= or +) from the drop-down menu.

Modifier - there are two possible value modifiers = and +. The = modifier uses the trim value directly from the selected flight mode. The + modifier uses the trim value from the selected flight mode and then adds the trim value from the flight mode you are configuring.

Example 1: If you are configuring FM1 and set the value to =0, FM1 will have the trim value of the current value of the same trim in FM0. In this case, changes made to the trim in FM1 will also affect the trim in FM0 and vice-versa.

Example 2: If you are configuring FM1 and set the value to +0, FM1 will have the trim value of the same trim in FM0, plus any trim changes made while in FM1, In this case, changes made to the trim in FM1 do not affect the trim in FM0. However, changes to trim values FM0 will affect trim values in FM1.

The below options can be configured for sensors:

• Name: Name of the sensor - up to 4 characters.

• Type: Options are custom or calculated. Custom sensors are defined by the hardware. Calculated sensors are a sensors whose value is calculated using other sensors values. See below for more information on calculated sensors.

• ID: This number indicates what type of sensore it is. It contains two parts. The first part is the ID number which defines the sensor type. The second part is the instance number for the hardware. If multiple sensors of the same type are configures, the instance numbers must be unique.

• Unit: The unit for the sensor. This unit is used when the sensor value is displayed on the screen or read aloud.

• Precison: Specifies the number of digits after the decimal point when the sensor value is displayed on the screen. The number is truncated based on this setting.

• Ratio: Specifies the ratio value to multiply with the sensor value as needed by some sensors.

• Offset: Specifies the offset value to add to the sensor value.

• Auto Offset: When selected, the first received value is used as offset. You can use the Reset telemetry option to reset the offset on already configured sensors.

• Positive: When selected, the value of the sensor will be displayed only when it is a positive number. Displays zero when the sensor value becomes a negative number.

• Filter: When selected, the sensor value becomes a rolling average of the last 5 received values.

• Logs: When selected, the value of this sensor will be saved in the log file. SD Card logging is configured in Special Functions or Global Functions.

Calculated sensors contain the additional configuration options:

• Formula: Type of calculation to use. Options include:

  • Add: Add the values of up to 4 designated sensors.

  • Average: Calculates the average value of up to four designated sensors.

  • Minimum: Find the minimum value of up to 4 designated sensors.

  • Maximum: Find the maximum value of up to 4 designated sensors.

  • Multiply: Multiplies the value of 2 sensors.

  • Totalize: Calculate the cumulative value of one sensor.

  • Cell: This is the formula for FrSKY Lipo battery sensor. It displays cell voltage specified by the number in "Cell index" field. If you specify "Lowest" in "Cell index" field, the voltage of the cell with the lowest is displayed. If you specify "Highest" in "Cell index" field, the voltage of the cell with the highest is displayed. If you specify "Delta" in "Cell index" field, the voltage difference between lowest and highest cell is displayed

  • Consumpt: Calculates the power consumption (mAh) by cumulatively add the values of current sensor.

  • Distance: Calculates the distance between the receiver and the radio using GPS sensor and altimeter values.

• Source 1, 2, 3, 4: The sensors that will provide the argument values that are used in the formula defined above.

The Tools page in Radio Settings is where you can select Lua script-based tools for execution. Lua scripts that are located on the SD card in the Tools folder will be listed here. Selecting a tool will execute it in full-screen mode. By default, EdgeTX includes several tools. Other tools can be downloaded and added to the SD card as well. The following tools are included in the default EdgeTX SD card.

Model Locator (by RSSI)

The Model Locator tool helps to find a lost model based on the RSSI (if still available). The widget produces an audio representation (variometer style) of the RSSI from the lost model. The widget will also display the RSSI in a visible colorized bar (0-100%).

Spectrum (INT)

The Spectrum Analyzer tool will show the strength of signals in the 2.4GHz band. It uses the internal MULTI-Module as a 2.4GHz spectrum analyzer.

The display shows frequencies on the 2.4GHz spectrum, from 2400MHz to 2480MHz. The X (horizontal) axis shows the frequency in MHz and the Y (vertical) axis shows relative signal strength.

T: Frequency at the center of the plot (fixed at 2440MHz) S: Bandwidth of the plot (fixed at 80MHz) T: Position of the cursor (vertical line)

Pressing ENT and scrolling left and right allows the T value to be changed, which will move the vertical line to highlight a specific frequency.

Wizard Loader

The Wizard Loader tool assists you in setting up a new model by running a setup wizard for a particular model type. Once the model type is selected, the wizard will take you through a series of prompts and then configure your selected model based on the information provided.

NOTE: The wizard does not create a new model, it only configures the currently selected model. You must manually create a new model first and then run the wizard. If you run this wizard on an already configured model, it will overwrite your model settings!

The Theme screen allows you to apply different colored themes to your radio. By default, the EdgeTX SD card comes with the themes shown above. Long pressing on a selected theme will give you the following options:

For more information about configuring Global Functions, refer to the Special Functions section as they are essentially the same.

There are several ways to install or update EdgeTX on your radio transmitter. You can use the online tool EdgeTX buddy or manually install/update the bootloader and firmware using the bootloader method. There are advantages and disadvantages to both ways, so really, it boils down to person preference.

EdgeTX Buddy

Pros

• Firmware and SD card contents are all located in one location

• It takes you step by step through the process

• Normally a simple process.

Cons

• Must use a Chromium-based browser to access (Chrome, MS Edge, Brave, Opera, etc.)

• You must have the correct SMT32 drivers installed on your computer. Usually, this is automatic. However, some computers install incorrect drivers, which can make this process more difficult.

Bootloader Method

Pros

• Flashing always works

• The flashing process is quicker.

• Does not rely on your computer for flashing

Cons

• Firmware, SD Card, and Sound files must be downloaded individually from different locations and placed manually on the SD Card.

Pressing the [PAGE>] button will take you to the Setup screen.

To be able to support many different types of radio transmitters, EdgeTX uses a generic control data flow that can be applied to any radio transmitter. In this data flow, any of the radio's physical controls (sticks, switches, sliders, pots) can be mapped to an input in the software. These inputs can be directly assigned or combined with other inputs into a single mix. These mixes can be modified by applying weights, offsets, and curves and are then assigned a channel for output. Final adjustments to the control data are made (including subtrims, curves, endpoint, and center values) before finally sending the control data to the RF module. The flowchart below depicts a visual summary of this control data flow. Detailed information about the flow is provided in the following sections Inputs, Mixes, and Outputs.

The Heli Setup page in Model Settings is an optional page that is available on custom-compiled versions of EdgeTX. The heli setup page is often used for collective pitch mixing (CCPM) used in flybared helicopters where the receiver directly controls the swashplate servos. Most flybarless helicopters do not need to configure this page. The outputs of the CCPM mixer are CYC1, CYC2, and CYC3, which need to be assigned to an output channel on the Mixes screen.

The heli setup screen has the following configuration options:

• Swash Type - Swash type for your model. Options are 120, 120x, 140, and 90.

• Swash Ring - Set the swash ring limit only as needed. 1 = maximum limit -> 100 or 0 = no limit.

• Long. cyc. source - Select source input.

  • Weight - Percentage value of the stick travel to use.

• Lateral cyc.source -Select source input.

  • Weight - Percentage value of the stick travel to use.

• Coll. pitch source - Select source input.

  • Weight - Percentage value of the stick travel to use.

Pressing the [PAGE>] button will take you to the Flight Modes screen.

Flight modes allow you to have different trim settings for each flight mode. Once multiple flight modes are configured, you can adjust the trim settings in each flight mode without affecting the trim settings in other flight modes (unless they are configured to do so). There are nine possible flight modes, with Flight Mode 0 being the default mode.

The Flight Modes Overview screen shows an overview of the configured Flight Modes. The information below is displayed for each flight mode row:

• Flight Mode

• Flight Mode Name

• Switch

• Trim settings (RETA)

Check FM Trims: When check FM trim is pressed, the trims for the current flight mode are temporarily disabled. This is used to test the impact of the current flight mode’s trims on the outputs.

Selecting a Flight Mode from the overview screen will open the configuration page, which has the following options:

Name: The custom name for the flight mode. If configured, this name will be shown on the upper left position of the main screen next to the battery voltage.

Switch: The trigger to enable that flight mode. It can be a switch, pot, telemetry, trim or logical switch.

Trims - To configure the trims, select the trim that you want to configure (each column is one trim). Then scroll to select the flight mode (0-8) that will provide the initial trim value and modifier (= or +). Select -- to disable the trim.

Modifier - there are two possible value modifiers = and +. The = modifier uses the trim value directly from the selected flight mode. The + modifier uses the trim value from the selected flight mode and then adds the trim value from the flight mode you are configuring.

Example 1: If you are configuring FM1 and set the value to =0, FM1 will have the trim value of the current value of the same trim in FM0. In this case, changes made to the trim in FM1 will also affect the trim in FM0 and vice-versa.

Example 2: If you are configuring FM1 and set the value to +0, FM1 will have the trim value of the same trim in FM0, plus any trim changes made while in FM1. In this case, changes made to the trim in FM1 do not affect the trim in FM0. However, changes to trim values FM0 will affect trim values in FM1.

Fade in: Gradually change the trim value when this flight mode is enabled. Specify the time in seconds (0.0 - 25.0) until the value change is completed.

Fade out: Gradually change the trim value when this flight mode is disabled. Specify the time in seconds (0.0 - 25.0) until the value change is completed.

Global Variables

Global variables are variables whose values are shared across all the configuration screens of a model. Their values can be used in weights, offsets, differential, expo settings, outputs, and in logical switch comparisons. The bottom portion of the flight mode configuration screen shows an overview of each global variable for the selected flight mode. For each global variable row, the following information is displayed:

• Global Variable Number: Displayed as GV(1-9)

• Global Variable Name: User-defined name for the global variable - up to three characters.

• Mode: Where the value of the global variable comes from. Options are:

  • Own: the global variable value for the selected flight mode is manually defined in the Value text field.

  • FM(1-9) - global variable value for the selected flight mode is inherited from the flight mode defined in the drop-down.

• Value: The current value of the global variable.

You can edit the value of the global variable by changing the value in the value text field. Selecting the global variable number will open the global variable configuration screen will give you the following options:

• Name - Name for the global variable. Three characters are allowed.

• Unit - (optional) Allows you to add a % label to the displayed values when selected. It DOES NOT affect how the values are calculated.

• Precision - Allows you to select the number precision options whole numbers (0.-) and decimal (0.0). The default value is 0.-

• Min - Defines the minimum that is allowed for the global variable.

• Max - Defines the maximum value that is allowed for the global variable.

• Popup - When enabled, a pop-up window will be displayed on the main screen when the value of this global variable changes during normal use.

• FM1 -> FM8 - Allows you to select the global variable inheritance for the flight mode. Long press the field to switch between Own and Inheritence mode. In Own mode, you can define the global variable value for the selected flight mode. In Inheritance mode, you can select the Flight Mode that the global variable will inherit the value from.

Pressing the [PAGE>] button will take you to the Inputs screen.

The Setup screen is where you start to configure your model. It contains the following settings:

Name - Name of the model. The maximum number of characters is 10.

• To edit the text, using the [roller] or [dial], press the button, scroll to select the desired letter, then press the button again to move to the next space. To toggle between lower and upper case, long-press the button. Press the [RTN] button to exit out of text editing mode.

Image - Image displayed on the main view (only for radios with 212 x 64 displays).

Timers

Timer 1/2/3 - There are 3 configurable timers in EdgeTX. The following configuration options will be displayed once the timer is no longer set to OFF:

Timer 1 [Mode] [Switch]

[Mode]: The options include:

• OFF- The timer is not used

• ON - The timer runs all the time

• Strt (Start) -The timer starts once the configured switch is activated. After the time is started, the timer ignores the switch position.

• THs (Throttle) - The timer starts once the throttle is raised and the configured switch is activated. The timer will stop counting if either the throttle position is lowered back to the minimum value or the configured switch is deactivated.

• TH% (Throttle %) - The timer counts proportionally to the throttle. It counts in real-time at full throttle and half speed at 50% throttle.

• THt (Throttle Start) - The timer starts once the throttle is raised and the configured switch is activated. After starting, the timer ignores the throttle position and will keep counting unless the switch is deactivated.

[Switch]- Select the switch that will trigger the timer to start. If no switch is selected, the timer will trigger based only on the configured mode. In addition to a switch, you can also select a trim, a telemetry source (triggered when telemetry data is received from that source), or physical activity (stick movement or button press) (labeled as ACT)

Name: Name of the timer

Start- The time used for the timer's advanced functions. The default value is 00:00 and when left as such, the timer operates like a stopwatch, counting upward until stopped. If a different time is entered in this box, then the additional field will appear next to the time with the options: Remain or Elaps.

If set to Remain, the counter will function like a countdown timer - counting down from the designated time to zero and then alerting the user. If set to Elaps, the timer functions like an alarm, counting up from zero until the designated time and then alerting the user.

Persist (Persistence):

• Off - The timer value is reset when switching models or when the radio is turned off / on.

• Flight - The timer value is NOT reset when switching models or when the radio is turned off / on. The timer value is only reset when the Reset flight option is selected in the Reset menu.

• Manual Reset - The timer value is reset only when it is individually selected to be reset (example: Reset timer1) in the Reset menu.

Minute (Minute Call) - If selected, you will be notified every minute that passes as described in the Count Down option.

Count Down:

• Silent - No notification is given until the timer reaches zero. When it reaches zero, you will hear one beep.

• Beeps - The radio will beep every second starting at the time designated.

• Voice - The radio will count down by second starting at the time designated.

• Haptic -The radio will vibrate every second starting at the time designated.

Function Switches

The functions switches are a type of multiposition switch (on select transmitters) that are managed directly by EdgeTX. Physically, they look like a regular 6-pos switch but are much more flexible.

Unlike other switches managed at the radio level, function switches are defined per model and configured in the model setup page. They contain the following configuration options:

Switch Type

• None: the switch is disabled

• Toggle : they are active only during the push duration

• 2POS: pushing the switch will alternate the state between OFF and On

Switch group

A traditional 6POS is a group of 6 switches that work together, where only one can be active at a time. Function switches expand that concept and let you choose how the switches should be grouped.

'-' defines a function switch with no group. Pushing it will only affect this switch.

'1', '2' or '3' define groups. All the switches in a group act together, where only one (the last pushed) can be active.

Always on groups

Selecting this check box makes the assigned group act like a traditional 6-position switch where one button from the group must be on at all times.

Startup Position

Start - Defines the state that each switch will be in when the model is loaded.

• ↑ Switch is inactive

• ↓ Switch is active

• = Switch is set to the same state it was in when the model was last used (it keeps old state).

Trims

E.Limits (Extended Limits) - When enabled, it increases the minimum and maximum range for the output values to -150 and 150. Extended limits are necessary if the full range of the control surface cannot be reached with standard limits.

E. Trims) Extended Trims: Increases the maximum trim adjustment value from ±25% to ±100%.

Reset - This resets all trim values to zero.

Show trims: When set to Yes, it will display the numerical trim value on the trim bar. When set to CHANGE, it will display the numerical value once the trim is no longer at zero.

Trim Step: Defines the amount of increase/decrease in trim when the trim switch is pressed.

• Course = 1.6%

• Medium = 0.8%

• Fine = 0.4%

• Extra Fine = 0.2%

• Exponential = 0.2% near the center and the step value increases exponentially as the distance from the center increases.

Throttle

The throttle related configuration options below are displayed in collapsible menu.

T-Reverse: When enabled, this option reverses the output direction of the configured throttle channel.

T-Source: The source that will be used for the throttle.

T-Trim-Idle: When enabled, the throttle trim will only affect the bottom portion of the throttle band.

T-Trim-SW: The trim switch that will be used to trim the throttle. It is possible to substitute the throttle trim switch with the aileron, rudder, or elevator trim switches.

Preflight Checks

Whenever a new model is loaded, EdgeTX will conduct pre-flight checks based on the checks that are configured on this page. If any of the checks are failed, EdgeTX will give the user an audio and visual warning that must be acknowledged before using the model. The following preflight checks below are displayed in collapsible menu.

Checklist - When this option is selected, the model notes file will be displayed when the model is loaded. A valid model notes file must be in the Models folder on the SD card. The model notes file must be a .txt file and must have the EXACT same name as the model it is for, for example: Mobula6.txt. The text in the file is up to the user.

T-Warning - When selected, the radio will check that the throttle is at the minimum value for the configured throttle source in the T-Source configuration option.

Cust-Pos - When this option is selected, the value designated in POS.% will be used for the T.Warning.

Pos.% - minimum value of the throttle for the throttle warning when Cust-Pos is enabled.

S-Warning - The section displays all the switches that are configured on the radio and allows you to select which position is the correct position for the switch state check. Selecting the switch will cycle through the available switch positions or turn the check off for the switch completely.

Pot warn- When activated, this option checks the position of the pots & sliders. There are three options - OFF, ON and AUTO. When ON or AUTO is selected, buttons for the available pots and sliders will appear. To enable the Pot warning for an individual Pot, select the pot with the [roller] or [dial] and click the button to highlight it. Highlighted pots are enabled.

• OFF - Pot and slider positions are not checked.

• Manual - Positions are checked against manually configured pot and slider positions. To manually set the check position, select manual the from menu, select the item that you want to set, and long-press the [Enter] button to set its current position for the check.

• AUTO - Positions are checked for pots and sliders and compared to the last automatically saved position before the radio was turned off or the model was changed.

Ctr Beep - Allows you to turn on/off the center beep function for the individual sticks, pots, and sliders by highlighting them with the [roller] or [dial] and pressing the button. When a switch is highlighted, the function is enabled.

Glob. Funs - When enabled, global functions programmed in the radio settings will apply to this model. When disabled, global functions will not apply to this model.

ADC Filter - Enables/disables the ADC filter for this model. The global option will take the value designated in the radio settings, which is on by default.

Internal / External RF

The configuration settings for both the Internal and External RF sections work the same. The only difference is that the Internal RF section is for configuring the built-in module and the External RF section is for configuring an RF module in the external module bay.

The configuration options are: off or the module name of the installed module as configured in the Radio settings. Configuration options are unique to each installed module. Please consult the manufacturer's documentation for configuration options.

Receiver number - A receiver number is a user-assigned number for a model that is sent to the receiver when bound. Each model must have a unique receiver number. However, models using different protocols may have the same receiver number without issues. EdgeTX will inform you when a receiver number is unique or if it is already being used with a text above the number field.

Trainer

Trainer Mode - The Trainer Mode option is where you can configure the CPPM passthrough mode and method. When enabled, this allows the CPPM signals from a radio in Slave mode to be passed through to another radio in Master mode which will then pass the signal to the model it is connected to. CPPM passthrough can be used for several different use cases, such as: connecting a head tracker, Instructor / Student training mode, and controlling complex models that require more stick inputs than available on a standard transmitter.

Master mode - This is the mode for the radio that will be connected to the model. This radio also shall configure the special/global function (Trainer) to activate the passthrough mode. When the passthrough mode is activated, the CPPM signals from the radio in Slave mode will be sent to the model for control.

Slave mode - This is the mode for the radio that will pass it's CPPM values to the radio in Master mode, which are then sent to the model.

Below are the possibile configuration options:

• Off - Trainer mode is not used for this model.

• Master / Jack - Master mode using a cable connection.

• Slave / Jack - Slave mode using a cable connection.

  • Channel Range - This is the range of channels that will be sent to the radio in Master mode. Channel 10 is the recommended last channel to use.

  • PPM Frame - The first field is the length of the PPM frame. The second field is the stop length/delay between pulses. The dropdown is to select the polarity of the signal. The frame length is automatically adjusted to the correct value when the number of transmitted channels is changed. However, this automatically assigned value can be manual changed. Note: In most cases, the default setting does not need to be changed.

• Master / Bluetooth - Master mode using a Bluetooth connection (if installed in radio).

• Slave / Bluetooth - Slave mode using a Bluetooth connection (if installed in radio).

• Master / Multi - Master mode using an additional externally mounted Multi-protocol module for the connection. For more information on this setup, see Set-up wireless trainer with a Multi -protocol module

Enabled Features

The Enabled Features section allows you to configure which pages are visible in the selected model's radio setup and model settings area of EdgeTX. The page names are displayed in a collapsible menu with the following configurable options:

• Global - When selected, the tab will take the global value configured in the Enabled Features area in Radio Setup. The configured global value will display next to the option.

• On - When selected, this tab will be visible when this model is loaded.

• Off - When selected, this tab will not be visible when this model is loaded.

USB Joystick

The USB Joystick has two possible modes, Classic and Advanced.

In Classic mode, the radio's configured output channels will be sent to the target device in numerical order and mapped to the device's preconfigured USB controller axes and buttons. Below is the default channel mapping for Microsoft Windows.

• Ch1 - X Axis

The Manage Models screen allows you to create new models, select which model is active, create and apply model labels, and create model templates.

Selecting & managing existing models

The active model's name will be highlighted (yellow in this case) and displayed on the screen's top bar. Double-tapping an active model will give you the following options:

• Duplicate model - This option creates an exact duplicate of the model with the same name. Changes to the model name or other settings need to be made in the Model Settings tab.

• Label Model - When this option is selected, all configured labels will be displayed and can be selected for this model. More Information about Model Labels is below.

• Save as template - this option saves a copy of the model as a model template.

Double-tapping on a non-active model (unhighlighted) will give you the following options:

• Select model - this option selects this model as the active model.

• Duplicate model - same as described above.

• Delete model - this option moves the model to the deleted folder on the SD Card. Only models that are not active can be deleted.

• Label model - same as described above.

• Save as template - same as described above.

Creating a new model

To create a new model, select the New Model button in the upper right corner. You will then be presented with the following options:

• Blank Model - This will create a blank model with only the default options configured.

• PERSONAL - This option will allow you to select one of your saved model templates and then create a copy of it as a new model.

• SoarETX - This will display pre-configured model templates for radio-controlled model sailplanes.

• WIZARD - This will launch the new model wizard and create the model as configured in the wizard.

Model Labels

Model labels allow you to give each model one or more labels. You are then able to filter the models displayed in the Model Select screen based on the labels that you select. This allows people with many configured models to find them easier. By default, the Favorites and Unlabeled labels are created automatically. All models are considered unlabeled until a label is applied to them.

Filtering models using labels

To filter the visible models based on their labels, select the filter or filters from the left column. It will automatically filter out the models that do not have those model labels.

Assigning labels to models

To assign a label to a model, double-tap on the model or press [Enter] when the model is selected and then select Label Models. Once selected, all configured labels will be displayed and one or more labels can be selected for this model. Labels applied to the model will be designated with a check icon.

Creating new model labels

To create a new model label, select the New button on the bottom left of the screen. The Enter Label pop-up will appear and you can enter the desired label name. Select Save to save the new label.

Editing model labels

Long press [Enter] or long tap on desired label and you be shown a menu with the following options:

• Rename Label - change the label's name

• Delete Label - Deletes the label from the label list and from all models that have it assigned.

• Move Up - positions the label higher on the list

• Move Down - - positions the label lower on the list

Sorting Models

The icons below the label list are for sorting the filtered models. Models can be sorted either alphabetically or by the last time they were selected as described in the image below.

Logical Switches are virtual two-position switches whose values (ON/OFF or +100/-100) are based on the evaluation (true/false) of a defined logical expression. Once configured, logical switches can be used anywhere in EdgeTX that a physical switch can be defined.

The Logical Switches page shows you all the configured logical switches as well as an overview of their configured options.

Selecting a logic switch will give you the following options:

• Edit - Opens the Logical Switches configuration page for the selected logical switch.

• Copy - Copies the selected logical switch

• Paste - Pastes a copied logical switch onto the selected logical switch. Note: it will overwrite the selected logical switch.

• Clear - Deletes all configuration options for the selected logical switch.

After selecting to edit a logical switch, you will have the following configuration options:

• Func - The logical function that you want to use. See Logical Switch Functions below for a description of the possible functions you can use.

• V1 - The first variable in the expression to evaluate.

• V2 -The second variable in the expression to evaluate.

• AND switch - Switch that must be active to allow the logical switch to be evaluated for activation.

• Duration - The duration that the logical switch will remain active (true) once meeting activation criteria.

• Delay - Delay between when the activation criteria for the logical switch has been met and when the logical switch changes to the activated state (true).

Logical Switch Functions

In the expression, a and b represent sources (sticks, switches, etc.), and x represents the constants (values) to be compared.

Pressing the [PAGE>] button will take you to the Special Functions screen.

The Curves screen allows you to define custom curves to use in the Inputs, Mixes, or Output screens. The curves screen will show the configured custom curves, with a graphical representation of each curve.

Selecting one of the curves or empty curve slots will open the configuration page for that curve.

Curves Configuration

The curve configuration screen has the following configurable options:

• Name - Name for the curve. Only 3 characters are possible.

• Type - Type of curve: Options are Standard and Custom

  • Standard - Horizontal axis points are fixed values based on the number of points. Vertical axis points are adjustable.

  • Custom - Both horizontal and vertical axes are adjustable.

• Count - number of points in the curve. Press the [Enter] button to modify the number of points. Long-pressing the [Enter] button will give the following additional options:

  • Preset - Allows you to set the curve to one of the preset slope values (-45 to 45 degrees in 15 degree increments). The curve will have 5 points, and smoothing is not enabled by default.

  • Mirror - Mirrors the selected curve.

  • Clear - Clears all curve values from the selected curve.

• Smooth - When enabled, connects the points with curved lines instead of straight lines.

Editing Curve Points

After the last configuration option (Smooth), you will automatically begin to scroll through the configured points on the curve. To change the values of the points, press the [Enter] button and then adjust the values as desired. For Standard curves, you will only be able to adjust the Y value. For Custom curves, you can adjust both the X and Y values.

Pressing the [PAGE>] button will take you to the Logical Switches screen.

The Inputs screen is where you map your physical radio controls (for example: sticks, sliders, and pots) to a software input to be used by the radio. After the control has been mapped, it is then possible to apply modifiers to the inputs, such as a weight, offset or curve, which will then be applied anywhere that input is used. Although it is possible to also assign switches as inputs, it is normally not needed as switch outputs seldomly need to be modified by a weight, offset or curve. By default, EdgeTX will automatically map your controller sticks to Aileron, Elevator, Throttle, Rudder based on the default channel order defined in Radio Setup.

Selecting an existing input line and pressing [Enter] will toggle between Copy/Paste mode and Move mode. In Copy/Paste mode, a copy of the input line is made which can be pasted in the desired input line. In Move mode, the selected input can be moved to a different line. Press the [Return] button to exit this mode.

Selecting an empty input line and pressing [Enter] will create a new input and open the input configuration page.

Selecting an existing input line and long-pressing [Enter] will give you the following options:

• Edit - opens the input configuration page for that input line.

• Insert before - Inserts a new input line before the selected input.

• Insert after- Inserts a new input line after the selected input.

• Copy - copies the selected input line.

• Move - selects the input line to be moved. The input is moved using one of the paste commands after a new line is selected (i.e. cut & paste).

• Delete - deletes the selected input line.

• Paste before - pastes the copied or moved input line before the selected input line.

• Paste after - pastes the copied or moved input line before the selected input line.

Input configuration page

The input configuration page allows you to edit the input configuration parameters. To the right of the configuration parameters, you can see a live graph that shows how your configuration options will affect the slope of the input.

Input Name - Name for the input. Three characters are possible.

Line Name - Name of the individual line in the input. Multiple physical inputs can be mapped to one input by adding an additional input line under the input.

Source - The physical control used for the input. In addition to physical controls, you can also specify MAX (always returns 100), cyclics, trim switches, channel values and more. Moving the physical control after the source has been selected will automatically map it to that input.

Weight - Percentage value of the stick travel to use (often referred to as "rates"). Long-pressing here will switch from numerical value to a global variable.

Offset - The value added to or subtracted from the input source.

Curve - Specifies the type of curve that will be used. The following curve options exist:

• Diff - Multiplies only the range above or below the middle (0) by the specified %.

• Expo -The input value is changed exponentially. Increasing the % will result in a gentle slope near the middle(0). Decreasing the % will result in a steep slope near the middle (0). With a % of 0, the slope will be linear.

• Func -

Modes - Specifies which flight modes this input is active for.

Switch - The switch that activates the input line. If no switches are defined, then it is always active.

Side - Specifies the input range for which this line setting is valid. If you select ---, it will be valid in the entire range of Source values. If you select x>0, it will be valid in the upper half of the value of Source. If you select x<0, it will be valid in the lower half of the value of Source.

Trim - Specifies whether or not to include the trim values in this input. Additionally, you can select a different trim to use for this input.

Pressing the [PAGE>] button will take you to the Mixes screen.

The Special Functions section is where you can configure the special functions that are included in EdgeTX. These special functions add additional functionality beyond normal model controls, such as enabling trainer mode, playing a sound, adjusting the radio backlight, adjusting radio volume, etc. On the special functions screen, you will see all configured special functions as well as some of the configured options such as function name, activation switch, if the function is enabled, and other configuration options.

Pressing the [PAGE>] button will take you to the Telemetry screen.

To be able to support many different types of radio transmitters, EdgeTX uses a generic control data flow that can be applied to any radio transmitter. In this data flow, any of the radio's physical controls (sticks, switches, sliders, pots) can be mapped to an input in the software. These inputs can be directly assigned or combined with other inputs into a single mix. These mixes can be modified by applying weights, offsets, and curves and are then assigned a channel for output. Final adjustments to the control data are made (including subtrims, curves, endpoint, and center values) before finally sending the control data to the RF module. The flowchart below depicts a visual summary of this control data flow. Detailed information about the flow is provided in the following sections , , and .

EdgeTX uses the icons below to designate different types of sources.

Telemetry is data received from the model to the radio from various sensors. These sensors may be included in the radio receiver or flight controller or may be separate sensors, such as GPS, variometer, or magnetometer. The received telemerty data can be displayed by EdgeTX in widgets, configured in alarms or audio call-outs.

The Telemetry screen is where you configure these sensors to use in EdgeTX. Below are the following configuration options:

Sensors

The following options are listed under the sensor list.

• Discover New: When selected, it will look for new sensors on the model and automatically configure them. If the sensor list is collapsed when a new sensor is discovered, the newly found sensor will be visible on the sensor list (old sensors will remain collapesd/hidden).

• Add New: When selected, it will create a new blank sensor for that must be configured manually.

• Delete All: This option will delete all previously configured sensors.

• No inst. (ignore instances): This option prevents multiple sensors from reporting the same telemetry data.

If you long-press the [Enter] button for a specific sensor, the following options will be displayed:

• Edit: Allows you to edit the sensor's configuration options.

• Copy: Creates a copy of that sensor.

• Delete: Deletes that sensor.
