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 STM32 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.

Whichever way you choose, there is a guide that will help you. Below are the migration guides and installation guides for both methods:

Generally

Color Screen Radios

Monochrome Screen Radios

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

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 except X9D series.

• bw212x64.zip (212x64 BW Screens) - X9D, X9D Plus, X9D Plus 2019

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.

I'm trying to flash using EdgeTX Buddy, but my handset isn't detected

1. Make sure when you plug the radio into the computer, that your handset is turned off. If you are getting a prompt about what mode to put the USB into, you will not be able to update. DFU mode, which used to flash the firmware, only operates when the handset is plugged in when in the OFF state.

4. Check with another USB cable... not all cables are created equally, and some cables are "charge only" cables.

I updated EdgeTX, and now my radio doesn't turn on, or acts strangely

1. Firstly, double check that you selected the correct name / target for your handset. Some incorrect selections will still boot, but buttons and controls will work incorrectly, or the screen will be upside down. Other combinations simply won't work at all, or make the radio seemingly go crazy, and you need to unplug the battery to get it to turn off. If you flashed the wrong target, simply go to EdgeTX Buddy, select the correct radio model, and flash the firmware.

2. Some handsets can have the wrong option bits set on the microcontroller, and as a result, will refuse to boot with EdgeTX 2.10 or later. The exact cause of this is unknown, but the fix is relatively simple. See the (collapsed) instructions below for more information.

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

Buttons:

• [RTN] - Return / Back - Short press [RTN] button to return to the previous page, previous menu or cancel action

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%

• 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.

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

Display trims: Option to display the numerical trim value on the trim bar. Options are:

• No - Does not display the numerical trim value on the trim bar

• Yes - Displays the numerical trim value on the trim bar once the trim is no longer at zero.

• Change - Momentarily displays the numerical trim value on the trim bar (2 seconds) once the trim is no longer at zero.

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.

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.

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.

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:

• 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

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.

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).

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 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

• Ch 2 - Y Axis

• Ch 3 - Z Axis

• Ch4 - X Rotation

• Ch 5 - Y Rotation

• Ch 6 - Z Rotation

• Ch 7 - Dial

• Ch 8 - Slider

• CH 9 - Ch 32 - Buttons 1 - 24

In Advanced mode you can configure the following options:

Interface mode: This indicates to the target device (the device you are connecting your transmitter to) what type of device you are connecting. The options are Joystick, Gamepad, MultiAxis.

Circular cutout: For axis pairs (X-Y, Z-rX): By default, the range of the axis pairs is a rectangular area. With this option, the axis will be limited to a circular area (like gamepad controllers commonly are). Options are : None or X-Y, Z-rX or X-Y, rX-rY or X-Y, Z-rZ

Output channels 1-32

Mode: For each output channel, you can select the mode that you want to use for that channel. The available options are None, Btn, Axis, Sim.

None - Channel is not used

Btn - Channel is used to simulate a button. Configuration options include:

• Inversion - Inverts the output channel signal. Options are: On / Off

• Button Mode -

  • Normal - Each postion of a multiposition switch is represented by a button. The current switch state is represented by a continous button press.

  • Pulse - Similar to "Normal" mode. However, instead of continous button press it is represented by a short button press.

  • SWEmu - The toggle switch emulations a push button. The first press turns the virtual button on, the second press turns it off.

  • Delta - The change of the output channel is represented by 2 buttons. While the output value is decreasing, the first button is pressed. When the output value is increasing, the second button is pressed. If there is no change, then no buttons will be pressed.

  • Companion - This option should be selected when using your transmitter to control the simulator in EdgeTX Companion. It allows the multi-position switches to function properly in the simulator.

• Positions - The type of button that will be simulated.

  • Push - will only map to one button

  • 2POS - 8 POS - will map to the number of buttons that the switch has (ex: 3POS will map to 3 buttons).

• Button No: The button number that the output will be mapped to and sent to the target device as.

Axis - The channel is used to simulate an axis and will be mapped to one of the target device's default axes.

• Axis options are: X, Y, Z, rotX (rotation x), rotY, rotZ

Sim - The channel is used to simulate a common sim axis and it will be listed on the target device as the selected option (ex: Thr)

• Sim Axis options are: Ail, Ele, Rud, Thr, Acc, Brk, Steer, Dpad

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.

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), MIN (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"). In addition to percentage value, you can use other inputs, physical controls, MAX (always returns 100), MIN (always returns -100), cyclics, trim switches, channel values and more, using the "SRC" button.

• Offset - The value added to or subtracted from the input source. In addition to percentage value, you can use other inputs, physical controls, MAX (always returns 100), MIN (always returns -100), cyclics, trim switches, channel values and more, using the "SRC" button.

• 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 %. In addition to percentage value, you can use other inputs, physical controls, MAX (always returns 100), MIN (always returns -100), cyclics, trim switches, channel values and more, using the "SRC" button.

  • 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. In addition to percentage value, you can use other inputs, physical controls, MAX (always returns 100), MIN (always returns -100), cyclics, trim switches, channel values and more, using the "SRC" button.

  • Func -

When selecting the gear button at the bottom of the screen, the following option window will be displayed.

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.

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

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

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 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.

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

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

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

Show mixer monitors - Selecting this option will display a bar graph on the mix channels showing the current value for that mix channel.

The upper right portion of the mixes configuration page contains a channel monitor for the selected mix line. It shows the output (top) and mix (bottom) values. The following configuration options are also available:

• Name - Name of the mix (optional). Up to 6 characters are allowed.

• Source - The source for the mix. In addition to inputs, you can select sticks, pots, sliders, trims, physical and logical switches, heli mixer outputs, trainer import channel values, and other channels, using the "SRC" button.

• Weight- Percentage of the source value to use. In addition to percentage value, you can select sticks, pots, sliders, trims, physical and logical switches, heli mixer outputs, trainer import channel values, and other channels, using the "SRC" button.

• Offset - The value added to or subtracted from the source. In addition to a fixed value, you can select sticks, pots, sliders, trims, physical and logical switches, heli mixer outputs, trainer import channel values, and other channels, using the "SRC" button.

• Switch - The physical switch that activates this mix line (optional). If no switch is selected, then the mix will be active by default.

• Slow down - Adjusts the transition speed for source value decreases. Specify the time to transition from -100% to + 100% in seconds. You can specify a range from 0.0 seconds to 25.0 seconds.

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.

Type: Can be set to any of the following

• None : basically disabled

• Toggle : customizable switch is only "active" while being pushed

• 2POS : pushing the switch will alternate it's state. i.e. OFF push ON push OFF ....

Group: This is where you choose how the individual switches should be grouped. You can choose for them to be in a single group (the default, Group 1), and then they can be used like a traditional 6POS switch. Or, you can define them to be in seperate groups (e.g. as shown for SW1-SW3 and SW4-SW5 above), or even for some switches to not be in a group at all (e.g. SW6 as shown above). You can use the various groups as a source for inputs or mixes via the GR# option, where the # represents the number of the group (e.g. GR1, GR2).

When switches are grouped, only one switch in the group can be active at a time. Additionally, you can specify that one switch in the group must always be on "Always on".

Startup: Here is where you specify the startup state for either a 2POS customizable switch not in a group, or for a group of customizable switches. You can specify it to be "Last" (remember the last state when the transmitter was powered off or model changed) or in the up (released) or down (pressed) state.

OFF / ON Colors (on compatible handsets): Some handsets support configuring the color of the customizable switches. If so, the OFF and ON color pickers will be shown for each customisable switch (as shown below) and you will be able to pick your preferred colour for each state. Black represents when the customizable switch is not illuminated.

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.

• Popup - When enabled, a popup message will be displayed when the value of a GV changes with the new GV value (see image below).

• 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.

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.

  • Custom - Both horizontal and vertical axes are adjustable.

• Number of Points - number of points in the curve

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

• 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. This line will be shown in bold and highlighted if the input for this channel is in the lower half of the range.

• Max - Maximum output limit. Commonly used to prevent servo binding on models that use servos for the control surfaces. This line will be shown in bold and highlighted if the input for this channel is in the upper half of the range.

• 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.

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).

• Persistence (Sticky Switch only) - Preserves the value of the sticky switch when turning the radio off, or changing models, and restores the saved value on power on or selecting the model again.

Logical Switch Functions

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

The Special Functions section of Model Setup, as the name implies, 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.

Selecting an already configured special function will give you the following options:

• Edit - Opens the special function configuration page

Options are !1x (do not change at startup even if the switch is active), 1x (change once), 1s thru 60s (change every xx seconds). This is useful because when the switch has been activated, the user can still manually switch screens, and then it will change back to the defined screen after the defined duration.

Trainer - Enables trainer mode.

• Value - Specifies which controls will be given over to the student. Options include Axis (all sticks / primary controls), Rud (Rudder), Ele (Elevator), Thr (Throttle), Ail (Aileron), and Chans (all channels).

Vario - Enables the variometer beeping sound for the ascent and descent of the model.

Volume - Changes the radio volume. The change source is specified in the Volume dropdown.

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.

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.

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!

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 Radio Setup screen is where you configure basic settings for your radio. It contains the following options:

Date - The current date. This date is used for the SD card log files.

Time - The current time. This time is used for the SD card log files.

Splash Screen - Duration that the splash screen will be displayed.

Startup Sound - Toggles whether to enable/disable startup sound.

Pwr Off delay - The delay between when the power button is pushed and when the radio shuts off. The options are: 0s, 0.5s, 1s, 2s, 3s, 4s. It is recommended to set at least a 1s delay in order to prevent the radio from being shut off in the case of an accidental button press.

Power Auto Off - If enabled, the radio with automatically power off after the configured amount of inactivity, if there is no RF module with active telemetry, or an active trainer connection.

Power ON/OFF Haptic - When enabled, the radio with use the vibration motor to give a haptic pulse when powering the radio on (indicating when the power button can be released) and when the transmitter is powering off.

Owner ID - Custom registration ID used only for users with FrSky ISRM/ACCESS modules.

Country code - Used by some RF modules to ensure adherence to local regulatory RF requirements. Options are America, Japan, Europe.

Voice language - Language for the voice pack. This setting and the voice pack folder on the SD card must match for the sounds to be played.

Units - Units of measure. Options are metric or imperial.

PPM Units - Level of accuracy for PPM values are displyed. Options are 0.-, 0.0 or us (μs/microseconds).

Play delay (sw. mid pos) - The minimum time in milliseconds a switch must be in the middle position before a special function will get activated. This is used to prevent the middle position from being activated on a three-position switch when switching from low position to high position.

USB Mode - Sets the default action when a USB cable is plugged into the USB data port and the radio is powered on. Options are: Ask, Joystick, Storage, and Serial.

Hats Mode: how the hat switches will function (NV14, EL18 and PL18/PL18EV only).

• 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.

Rotary Encoder Mode - Set to Normal by default. The Inverted option reverses the direction of the roller.

Default Channel Order - The default channel order for new models and the trainer screen. The letters stand for: A = Aileron (Roll), E = Elevator (Pitch), T = Throttle, R = Rudder (Yaw). Changing this setting does not affect existing models.

Mode - The stick mode that will be used for the transmitter. Defined by what actions the left stick takes. The options are:

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.

Once you have your desired color, press the theme logo in the upper left corner to go back to the Edit Theme screen to select another color variable to edit. Once you are finished, press the theme logo to exit the Theme Editor and save your changes.

The SD Card screen shows you the contents of your SD card, allows you to navigate the folders and interact with the files in the folders. All folders contain a README.txt file that describes what type of files belong in this folder. After selecting a file in one of the folders, you will be presented with some of the options below, depending on the file type that was selected:

• Assign bitmap - Assigns the selected image file as the model image of the currently selected model.

• Copy - Copies the selected file.

• Delete - Deletes the selected file.

• Execute - Executes a Lua script. Used for files ending in .lua

• Flash [target]- Flashes the selected firmware file to the select target module. Examples: Flash Bootloader, Flast Internal Multi.

• Paste - Pastes the copied file.

• Play - Plays the selected sound file.

• Rename - Renames the file.

• View text - Views the selected .txt, .csv, and .lua files.

The folders listed on the SD card screen are the same as what you will see when connecting your radio to your computer. Below are the folder names and explanations for all the folders that come with the default EdgeTX SD Card.

FIRMWARE

Place the firmware files that you want to flash in this folder. This folder is empty by default (except for the readme.txt file). When selecting a .bin file you will be given the option to flash the firmware to a particular module. Also, only firmware files in this location will be visible from the bootloader menu. Selecting a .frsk file will give you the option to "Flash RX by int OTA".

IMAGES

Place your custom model or splash screen image files in this folder. This folder is empty by default (except for the readme.txt file). Selecting an image file will give you the option to Assign Bitmap, which assigns the selected image file as the model image of the currently selected model.

The ideal image size for model images used for thumbnails on the Model Manager screen is 156x92 pixels. If you plan to use the Model Info widget, you may want a increase the image size to 192x114 pixels for better visual quality at the increased size. For performance reasons, it is NOT recommeded to use a higher resolution image. The picture format should be .png. The image file name should not exceed 9 characters.

Users can configure a custom image to be displayed during the radio shutdown by adding a custom shutdown.png to the IMAGES folder.

LOGS

MODELS

This is where the model files, label information, and preflight checklists are stored. Each model will have a model[#].yml file that contains all configured options. Additionally, there is a labels.yml file that contains all the label information for your models.

Models that are deleted via the radio will be moved to the DELETED folder that is included in this folder. The remaining model files are what will be visible on the Model Select screen.

Any model files that are found in this folder that are not listed in the Models.yml file (if used) will be moved to the UNUSED folder.

If you have configured the Display checklist option in model settings, the model notes file goes in this folder. 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.

RADIO

This folder contains the radio.yml file. This file contains all the radio configuration data. If this file is corrupted or missing, the radio will go into Emergency Mode and will create a new radio.yml file with the default settings.

SCREENSHOTS

SCRIPTS

SOUNDS

This folder is where the EdgeTX sound packs for your radio get placed. The sound packs are language-specific and correlate to the Voice language option in Radio Setup. Selecting a sound file from this folder will give you the option Play, which plays the selected sound file.

• File Name: 123456.wav (up to 6 characters plus .wav)

• Sample Rate: 32 kHz (or 16 Khz, 8Khz)

• Bits / Sample: 16 (or 8)

• Tracks: 1, mono

• Compression Codec: PCM

TEMPLATES

  • 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.

• Persistent: When selected the sensor values will be saved when switching between models or powering down the radio.

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

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.

• Resets all discovered telemetry sensor values.

• Resets all logical switch states

• Triggers the same checks as loading the model - i.e. throttle position, switch state, is failsafe set check, display pre-flight checklist if configured, stuck keys test, etc.

Reset timer 1 / 2 / 3 - Resets only the selected timer to zero regardles of the configured persistence setting.

Reset telemetry - This option resets all discovered telemetry sensor values.

The Hardware screen is where you configure hardware specific-settings for your radio. It contains the following configuration options:

Battery meter range - Sets the maximum and minimum voltage for the battery meter. This should be set based on the type of battery you are using.

Battery Calibration - Set this value to match the transmitter battery voltage.

Check RTC voltage - When enabled, checks the RTC battery at startup and warns you if the battery voltage is low.

ADC Filter - Enables or disables the ADC Filter. This filter can also be enabled/disabled per model in the model settings.

Mute if no sound: - When enabled, puts the transmitter in mute mode until a sound needs to be played. This prevents interference noise from high-powered TX modules from coming out of the transmitter speakers.
