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.

Interactive checklist - This option is used with the Display checklist option. When this option is selected, any line of text in the checklist file that begins with = will display as a check box when the checklist is displayed. All displayed checkboxes must be checked by selecting them in order to close the checklist.

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.

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

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.

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.

Beep when centered

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

In order to update from OpenTX to EdgeTX you will need to have both OpenTX & EdgeTX Companion installed on your computer. You can download OpenTX Companion from: https://downloads.open-tx.org/2.3/release/companion/. You can download EdgeTX Companion from: https://github.com/EdgeTX/edgetx/releases (File name: edgetx-cpn-[operation system]-[version].zip)

Backing up your Models

Turn on your radio, navigate to Radio Settings, Hardware and scroll down to the bottom of the screen and select EEPROM backup. If you do not have this option, then your radio does not store your data in EEPROM and this step can be skipped.

With your radio powered on, plug your radio into your computer via USB. When prompted by your radio for the USB mode, select USB Storage.

With your computer, copy the entire contents of your SD card to a safe place on your Computer. If you ever decide to go back to OpenTX you can use these files again. If you backed up your EEPROM in the step above, check the EEPROM folder to make sure that there is a recent backup file in there.

Start OpenTX Companion.

Select the Backup radio to file icon from the left side of the screen as shown below. Select a saving location (desktop is fine) and give it a descriptive name.

After the file has been saved, close OpenTX Companion. Unplug the radio from the computer and power it off.

SD Card Preparation

Download and extract the EdgeTX SD card content for your radio type to your computer. The SD card contents can be found here:

The list below shows which .zip file to use for different radio types:

• c480x272.zip (480x272 Horizontal Color Screen) - TX16s, T16, Horus x10s,Horus x12s, most color screen radios...

• c480x320.zip (480x320 Horizontal Color Screen)

• c320x480.zip (320x480 Verticle Color Screen)- FlySky Nirvana NV14, EL18

• bw128x64.zip (128x64 BW Screens) -All monochrome screen radios

Delete everything from your SD card and copy the contents of the unzipped folder to your blank SD card. (If you did a format, ensure it is set to fat32)

Copy over any custom sounds, model images, widgets or Lua scripts to their respective folders.

Download the desired sound pack (if you didn’t transfer your existing sounds) (), unzip and copy to the "Sounds" folder on your SD card.

Flashing the EdgeTX Bootloader and Firmware

Download the current EdgeTX firmware. You can download the latest release .zip file (edgetx-firmware-vX.X.X.zip) directly from Github -

Unzip the file and save the correct .bin file (same name as your radio type) to the "Firmware" folder on the SD card for your radio.

Turn on your radio and navigate to the SD card screen. Open the "Firmware" folder and select the EdgeTX firmware file that you just copied to your SD card. Once the file is selected, select the option to "Flash bootloader". The bootloader will be flashed to the EdgeTX bootloader.

Exit back to the main screen and then shut off your radio.

Boot your radio in bootloader mode by holding trim switches T4 and T1 to center while pushing the power button on.

You should now see the EdgeTX bootloader. Select the option "Write Firmware". Select the EdgeTX firmware file that you saved to your SD card. Long-press to flash it.

After the flashing is complete, select "Exit". The radio will restart and you should be greeted with "Welcome EdgeTX".

When the radio starts with EdgeTX for the first time, you will get a warning: STORAGE WARNING - Missing or Bad Radio Data-. Press the white circle or roller to bypass the warning. Then you will get another STORAGE WARNING - Storage Preparation. Press the white circle or roller again. Once the SD card is prepared, the calibration screen will appear. Calibrate your radio.

At this point, you now have the EdgeTX Bootloader, Firmware and the SD card contents installed. The last step is to convert your models over from OpenTX and put them on the radio.

Restoring your Models from OpenTX

With your radio powered on, plug your radio into your computer via USB. When prompted by your radio for the USB mode, select USB Storage.

Open EdgeTX Companion. If you have not already done so, create a radio profile for your radio and make sure that it is selected as active.

In the upper left corner of Companion, select File, then Open, then select the OpenTX Backup file that you made at the very beginning. A warning message will be displayed. Click OK.

You will then see all your models from OpenTX in EdgeTX Companion. Click on the Write models and Settings to Radio button. It will warn you that it will overwrite all the models on your radio. Click Yes.

The models and settings will be written to the radio. A message will be displayed when complete. Click on OK. Unplug your radio from the USB port and close EdgeTX Companion.

Congratulations, you have now successfully migrated to EdgeTX!

All of your models have been updated to the EdgeTX .yml format and you have the EdgeTX sound pack installed. You are now ready to use EdgeTX.

On the NV14 and EL18 radios, it is possible to navigate the menu options using the Trim hat switches.

In the radio setup screen, you can configure the Hats Mode with one of the following options:

• Trims only: The Trim hat switches will be used to adjust the trim values only.

• Keys only: The Trim hat switches will be used to navigate the menu options (as described below)

• Switchable: Trim hat switch functionality can be changed between Trims and Keys on-the-fly.

To switch between modes on-the-fly

1. Configure Hats Mode as Switchable.

2. Press and hold the Left Hat.

3. Immediately after, press the Right Hat.

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.

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

Below is a summary of changes that affect the user interface and/or how EdgeTX functions. It does not cover all bug fixes. For a complete list of changes (including bug fixes), please read the release notes.

• Radio can be configured to automatically power off if left inactive ()

• Sticky logical switch state can be configured to persist across reboots ()

• USB joystick support for Android game pad functionality ()

• Even shorter power on/off delay option - 0.5 seconds ()

• Precision setting for mix delay up & down (in addition to the precision for "slow up/down" that was added in 2.10) ()

Color Screen Radios

• Radio user interface performance is significantly improved from that of 2.10 ()

• Top bar widget sizes can be changed ()

• File browser popup has filters to let you jump through the lists ()

• Full screen Lua widget "App mode", which gives widgets focus to allow for touch and key input ()

Monochrome Screen Radios

• Collapsible sections in radio setup tab to make it shorter ()

• 'Set Screen' special function that lets you switch to a (configured) telemetry screen ()

• Displays PPM value in channel monitor (in addition to 0.0/0.00 value) ()

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. This option is not shown on FM0, as it is always active unless another flight mode is specifically enabled.

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. When 3P is selected instead of the flight mode (0-8), the trim will act as a 3 position momentary switch.

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 model setup page is the default page for model settings and is where you start to configure your model. It contains the following settings:

Model name

Enter the desired name for the model. The maximum number of characters is 15.

Labels

Here you may assign a label from your defined label list. By default, the model label will be Unlabeled. More information on creating labels can be found on the page.

Model image

When the folder icon is selected, a window will pop up allowing you to select an image file from the images folder on your SD Card.

The Statistics screen presents you with statistics regarding radio usage. All data is reset once the radio is powered off. The following information is provided:

• SES - The amount of time that the radio has been turned on.

• THR - The amount of time that the throttle has been above the 0% stick position.

• TH% - The amount of time that the throttle has been above the 50% stick position.

Long pressing the [Roller] or [Dial] button will reset the Statistics and Debug screens.

Pressing [PAGE>] will take you to the Debug screens.

The Debug screen provides data points used by the developers when debugging issues in the software. Most users will not find the information useful on this screen unless debugging issues with developers. The following debug information is provided, and may change depending on handset capabilities and options configured.

• Free mem - Current free radio memory in bytes.

• Lua scripts

  • [D] - Maximum Lua duration in milliseconds.

The Channel Monitor shows both the output value (top bar) and mix value (bottom bar) for each of the 32 radio channels, spread across 4 pages of 8.

The 5th page of the channel monitor is the logical switches monitor. On this page, you will see the status (activated/non-activated) of all logical switches. Logical switches that are activated are highlighted.

Back-up SD Card Contents

Before making any updates to your radio, we ALWAYS recommend that you back up your current SD Card contents using the following steps.

With your radio powered on, plug your radio into your computer via USB. When prompted by your radio for the USB mode, select USB Storage.

With your computer, copy the entire contents of your SD card to a safe place on your computer. You can use these files again if you need to roll back the update.

If you're here reading this, you probably got stuck with something either while trying to update or after updating. So checkout the list of issues and possible resolution steps below, to see if something matches the problem you are having. If there isn't, either join us on (there is usually someone around who can help out), drop by our forum, or the if that is more your thing.

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%).

The Statistics screen presents you with statistics regarding radio usage. Except for Battery, all data is reset once the radio is powered off. The following information is provided:

• Session - The amount of time that the radio has been turned on.

• Battery - The amount of time that the radio has been on since the last reset.

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.

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:

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.

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

The icons at the top of the screen include (in order from left to right):

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:

• Set Active - Sets the selected theme as the active theme.

• Edit - Opens the theme editor to edit the selected theme.

The Trainer screen 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:

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.

Selecting Reset from the pop-up menu will give you the following options:

Reset session - When selected, this option:

• Resets all timers configured with a persistence setting of Flight to zero.

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

Model Independent

These are sounds that are not special to any specific model, and are located in /SOUNDS/language and /SOUNDS/language/SYSTEM on your radio's SD card/on-board storage when correctly configured.

The files in /SOUNDS/language/SYSTEM are automatically played by the radio in response to specific events, such as turning the radio on, telemetry being lost, switches being in the wrong position, etc.

You can also add Play Track Global Functions that will play in response to whatever trigger condition you wish.

Model Dependent

These are sounds that are specific to a given model, and are located in /SOUNDS/language and /SOUNDS/language/model_name on your radio's SD card/on-board storage when correctly configured. The files in /SOUNDS/language are available for use with Play Track Special Functions, and will play in response to whatever trigger condition you configure.

In addition to the Play Track Special Function, there is also the ability to configure audio be played by simply placing audio files into a directory with the same name as the model.

For example, for English, with a model named Ruxus 5, you would create a folder named /SOUNDS/en/Ruxus_5/ (note the need to replace spaces with underscores).

Then, just create/copy audio files (of the correct format!) for any of the following trigger events into that folder.

Model Load

Will be played after the startup switch checks are completed when turning the radio on or when switching to the configured model.

Filename: name.wav

Switches

Played on change of switch position.

Filename structure: switchID-position.wav

• SA-up.wav

• SA-mid.wav (if position present)

• SA-down.wav

Multi-position / Stepped Switches

Played on change of switch position.

Filename structure (hyphens added for clarity): P-switchNumber-position.wav

• P11.wav (Pot 1, position 1)

• P16.wav (Pot 1, position 6)

Logical Switches

Played when the logical switch changes state.

Filename structure: switchID-condition.wav

• L1-up.wav (true)

• L1-down.wav (false)

Flight Modes

Played on entering or exiting flight mode.

Filename structure: modeName-condition.wav (Note: No spaces in the flight mode name)

• ABC–off.wav

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.-

Custom (Mixes) Scripts take one or more values as inputs, do some processing in Lua code, and output one or more values. Each model can have several Mixes Scripts associated with it, and these scripts are run periodically. They behave similarly to standard EdgeTX mixers, but at the same time they provide a much more flexible and powerful tool.

Typical use cases:

• replacement for complex mixes that are not critical to model function

• complex processing of inputs and reaction to their current state and/or their history

• filtering of telemetry values

Here is an example of mixer script that accepts a source and constant value, and has two outputs that will be selectable in the mixer as sources.

The Version screen displays information about the current EdgeTX version that is being used:

• FW - Firmware name

• VERS - Firmware version

• DATE - Date firmware was compiled

• TIME - Time firmware was compiled

• OPTS - Build options that were enabled when compiled.

The Modules / RX Version gives you information about the activated RX modules for the currently selected model.

The Screen settings section of EdgeTX is where you can customize your main views and add additional views (up to 10 in total). When selecting Screen Settings from the main navigation menu it will open Main view 1. If other main views have been added, you may select them from the number tab at the top of the screen to adjust their settings. All main view tabs have the following configuration options and are configured individually:

• Layout - Selects the screen layout for the widgets. It is possible to divide the screen in up to two columns and up to 4 rows, with a widget in each cell.

• Setup Widgets - see below.

• Top bar - Toggles whether the top widget bar will be visible on the selected main view.

• Flight mode - Toggles whether the flight mode name (if configured) will be visible on the selected main view.

• Sliders - Toggles whether the slider bars will be visible on the selected main view.

• Trims - Toggles whether the trim bars will be visible on the selected main view.

• Mirror - Toggles whether to mirror the selected widget layout.

Selecting the user Interface button to the left of the Main view 1 tab will open the user interface configuration screen. It contains the following options:

• Top bar Setup Widgets button - Sets up the widgets that will be displayed on the top bar. See below for information on how to setup widgets.

• Widget Size - Allows you to configure the width of the widget zones to be shown in the top bar, at the expense of the number of widget zones you can have.

Setting up widgets

Selecting the setup widgets button will display the main view or top bar with the widget cells outlined in a hashed line. You can assign a widget to a cell by selecting the cell and then the widget you want to assign to it from the drop-down menu. After selecting the widget, it will then open the configuration options for the widget for further configuration. Widget descriptions and configuration options for widgets included with EdgeTX are below.

Tools

Pressing the [SYS] button from the Main view will open the Tools screen.

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. 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.

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!

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

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

Selecting an existing custom curve will display the following options:

• Edit - Opens the curve configuration page.

• 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.

Selecting the plus button to create a new curve will give you the following options:

• Edit - Opens the curve configuration page.

• 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.

Selecting Edit for a configured or unconfigured curve will open the curve configuration screen and display the following 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.

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.

The Trainer screen in Radio Settings is used to configure how the radio in Master mode will handle the signals from the radio in Slave mode.

For each of the four main control inputs (Ail, Ele, Thr, Rud), the following options can be configured (for each row, from left to right).

• Mode - How the radio in Master mode will handle the signals from the radio in Slave mode.

  • OFF - Stick values from the radio in Master mode will be used - no input from the radio in Slave mode.

  • Add - Adds the stick values from both the radios in Master and Slave modes.

  • Replace - Replaces the stick values from the radio in Master mode with the stick values from the radio in Slave mode. (Default)

• Source channel - The channel from the radio in Slave mode that is mapped the control input.

• Weight - Percentage of stick travel to use of the radio in Slave mode. Use negative values to change the stick direction.

• Cal (calibrate)- Sets the center stick value of the radio in Slave mode.

• Multiplier - This value changes the weight of all the sticks together.

This How-To shows the configuration of a low voltage battery alert. Let's assume we have a model that is using a 2S Lipo RX battery. We want to configure an alerts when the battery voltage drops below 7.4V.

Ensure that telemetry data is being received by the radio and the sensors have been discovered within EdgeTX before proceeding.

Step 1: Create a logical switch that activates when the battery voltage drops below a defined value.

Press the [MDL] button to open the Model Setup screen and navigate to the Logical Switches tab. Create a new logical switch with the following configuration:

• Function use a<x

• V1 is the telemetry sensor that you want to use for this alert. In this example we are using the RxBt telemetry sensor

• V2 is the voltage where you want the alarm to trigger

• Delay is recommended to configure a delay so that battery sags will not will not cause the alarm to trigger

This logical switch will activate when the TX battery is below 7.4V for the duration of 10 seconds.

Step 2: Create a that announces the battery value once the logical switch is activated.

Press the [MDL] button to open the Model Setup screen and navigate to Tab and create a new Special function with the following configuration.

• Switch: This is the logical switch that you configured in the previous step. In this example L01

• Func: select the Play Value function from the drop-down so that it will announce the battery voltage when triggered

• Value: Select the telemetry sensor that you configured in the previous step. In this example it is RxBt

• Repeat: Set the value for how often it should repeat the announcement. In this example it is every 10 seconds

There are various reasons on why you may want to disable the touchscreen. Unintentional touches during a flight could change your model configuration which can be a risk.

Therefore we can create a global function or special function using the No Touch feature to disable and enable the touch feature. While global functions apply to all models, the special function is defined on individual models.

Disable touch screen with a global function

In the following example we use switch SF to disable the touch screen with a global function.

Disable touch screen with a special function

Customizable switches or logical switches cannot be used in global functions. But we can use a special function to enable and disable the touch screen with a customizable switch.

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.

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

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

The user interface of EdgeTX can be navigated by physical buttons, the touch interface, or a combination of both.

Buttons:

• [SYS] - System Button - Short press [SYS] button to go to the

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

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

• Mode #

• Mode Name

A traditional 6 position switch/control is either a group of 6 switches that work together (where only one can be active at one time) or a single rotary switch that has six physical positions (detents). Some newer generation radios provide the "Customizable Switch" capability, which allows you to define type, grouping and startup state of the switches. Physically, they look like a regular 6 position switch which you will see on older handset designs, but they are much, much, more flexible.

Name: Whichever three letter name you wish to give each customisable switch.

Trims are used adjust the center position of a given stick axis. EdgeTX has the following time configuration options:

Reset - This resets all trim values to zero.

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

• Course = 1.6%

• Medium = 0.8%

There are model types where some or all of the trim switches on your radion are not used. Helicopters or drones with a flight controller usually don't need trims Also on many fixed wings you may not need all the 4 trims for throttle, rudder, elevator and aileron.

In the following example our model is a glider. Gliders don't need throttle trim. We also don't need the rudder trim, because we can adjust the rudder with the servo sub trim.

Gliders usually use differential on the aileron mixers. The plane rolls perfect when the differential is set to the correct value.

In this sample we will use the rudder trim buttons to adjust the differential of the ailerons. And we will be able to adjust this using the trims in flight.

Step 1: Disable the trims for rudder and throttle which are not needed. Then we can reuse them for other functionality. Enter the model menu and navigate to the page. Edit FM0 and disable the Throttle and Rudder trims. The yellow highlight color will be gone when the trims are disabled.

You can see the disabled trims also on the flight modes page. They now show a dash

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.

The Outputs screen 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 output channels. For each output line, it displays the values for the subtrim, minimum and maximum limits, direction, curve, and subtrim mode. After the last output line is the option Trims=>Subtrims. When this option is selected, it adds the current trim value to the subtrim value for each configured output. The trim value is then reset to zero.

The support for Bluetooth in EdgeTX is limited to:

• Bluetooth Trainer Mode

• Bluetooth Telemetry Streaming

The following Bluetooth options are not supported.

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

All previously configured sensors are listed here. The list is collapsible by clicking on the arrow icon to the right side of the Sensors label (and is collapsed when you initially open the page). The number of configured sensors will be displayed in parentheses, ex: (6), when the sensor list is collapsed. Sensors that have not received data since the model was loaded or the telemetry values were reset display --- for the values. The asterisk * to the left of the sensor value will flash when the sensor has received a data update. A solid asterisk* indicates that the sensors that are receiving regular updates. Sensors that are no longer receiving regular updates will not be marked with the asterisk*. See for a list of commonly used sensors in EdgeTX.

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.

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

• 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.

• Range - Specifies the ascent/descent range that will trigger the change in the Variometer beeping pitch. If climb/descent rate is within the range specified here, beeping pitch will change according to that value. When it goes beyond the range specified here, beeping pitch will stop changing. Units are meters/second or feet/second based on the Units setting on the page.

• 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.

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.

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 menu.

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

Prerequisites

In order to setup a wireless trainer connection with the Multi-protocolm Module, you will need the following:

• A student radio with a FrSky D16 capable TX module

• An instructor radio with:

  • A Multi-protocol module to serve as the RX

  • An additional TX module to use to communicate with the model (protocol does not matter, but must match the protocol use by the RX on the model)

Setup

Ensure that the model is bound to the desired TX module and operational on the instructor radio.

On the Instructor radio, configure the Trainer section of Radio Settings. See section for more information on how to set this page up.

On the Instructor radio, configure the Trainer section of Model Settings. For the Mode, select Master/Multi

On the Instructor radio, configure the special function Trainer. Designate a switch to activate the mode and make sure the function is enabled.

On the Instructor radio, configure the Internal RF and External RF sections in Model Setup. The RF Module's mode that will communicate with the Student radio should be set to Multi, FRSkyRX and RF Protocol: Multi. Also, configure a receiver number. Both the Instructor and Student radios need to use this same receiver number. The other RX module should be configured to communicate with the model.

One the Student radio, configure either the Internal RF or External RF (which ever module will be used) to communicate to the Instructor radio. If using a multi-protocol module it should be set to Multi, FRSkyX and RF Protocol: D16. Configure the receiver number to the same number configured in the step above.

On the Student radio, no configuration of the Trainer section in the Model Settings or Radio Settings is necessary, leave the Mode option in the Trainer section of Model Settings configured to Off.

Trainer mode is now configured.

You can test this by watching the channel monitor on the Instructor radio, activating trainer mode via the configured switch and moving the sticks on the student radio. If configured correctly, you should see the stick movements from the student radio on the channel monitor on the Instructor radio.

Selecting one of the 6 buttons on the Radio Setup screen will take you to one of the additional setting screens below.

Many of the additional settings here are self-explanatory. Only those settings needing clarification will be mentioned below.

Sound

Mode - configures when to play sounds.

The Hardware screen is where you configure hardware specific-settings for your radio. It shows all physical hardware objects (sticks, pots, switches) and allows for their modifications. It is also where you can calibrate your sticks and pots. It also contains additional configuration options.

Calibration

To calibrate your physical radio controls (sticks, pots, sliders & 6-position switch), highlight the [Calibration] option and press the [Enter] button. The radio will prompt you through the calibration steps.

The Mixes screen of Model Settings is where several Inputs can be combined into one "Channel Mix". These mixes are then assigned to a radio channel for output. This is also the place where switches, knobs or sliders are assigned to a channel for output. Similar to the Input section, it is also possible to assign a weight, offset or curve to a channel mix.

Selecting the + button will create a new mix and open the mixes configuration page. Selecting an existing mix will give you the following options:

• Edit - opens the mixes configuration page for that mix line.

The Mixes screen is where several Inputs can be combined into one "Channel Mix". These mixes are then assigned to a radio channel for output. This is also the place where switches, knobs or sliders are assigned to a channel for output. Similar to the Input section, it is also possible to assign a weight, offset or curve to a channel mix.

The Mixes screen shows you an overview of your configured mixes. Each row represents a mixer line and displays the following information from left to right: channel, weight, input, mix name switch. These items are described in the area below.

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

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

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.
