The purpose of this user manual is to consolidate information from the community about the setup, configuration, and use of EdgeTX. The goal is to be your "one-stop shop" for information about anything related to EdgeTX. It is broken down into the following areas:
If you would like to contribute to this guide, please take a look at the Contribute to the User Manual page.
The user guide explains all the configuration options available in EdgeTX as well as some high-level theoretical information about EdgeTX usage and model controls. It is broken into sections - one section covering the interface for Color Screen Radios and one section covering the interface for Black and White screen radios.
The How-to section will provide detailed instructions about how to configure model or user-specific use cases in EdgeTX. It will cover common use cases as well as rare and specific use cases. This section of the manual will steadily grow as new How-to articles are submitted by contributors.
The EdgeTX Companion User Guide will cover the different features and functions of EdgeTX Companion and the EdgeTX Simulator as well as common use cases for both. Note: This section is currently planned, but work on it has not been started.
This section of the knowledge base will contain links to additional resources that EdgeTX users may find useful. The external pages that are linked here are not maintained by EdgeTX. However, they are listed as they may be useful sources of additional information relating to EdgeTX.
See the Contributors section for a list of direct and indirect contributors.
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 theModel Setup screen.
The icons at the top of the screen include (in order from left to right):
Heli Setup (only visible if EdgeTX is custom compiled with this option.)

Pressing the roller from the main screen will also open the main navigation menu. You can then scroll using the roller to the desired menu option and select it by pressing the roller.
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%.
When switching from extended trims to normal trims, the extended trim value will remain until the trim is adjusted, then it will jump to the max/min normal trim value.
Display trims: When set to ON, it will display the numerical trim value on the trim bar. When set to CHANGE, it will display the numerical value once the trim is no longer at zero.
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.
For example, with Trim idle only enabled, the throttle stick at the lowest point might have a value of -80 and the center point will still be 0 and the highest point of 100. Without this enabled, the throttle stick at the lowest point might have a value of -80 however, the center point will be 20 and the highest point of 100.
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.
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.
Throttle, Throttle %, and Throttle Start can be triggered by a switch, dial, or the value of another channel instead of just the throttle. This is specified in Source field of the Throttle section in Model Setup
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)
Those items with a "!" mark in front of the trigger name mean that the condition is reversed. For example, "!SA-" means "when SA switch is not in middle/center position (= up or down)".
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.
Persistent:
Off - The timer value is reset when switching models or when the radio is turned off / on.
Flight - The timer value is NOT reset when switching models or when radio is turned off / on. The timer value is only reset when the Reset flight option is selected in the Reset telemetry menu.
Manual Reset - The timer value is reset only when it is individually selected to be reset (example: Reset timer1) in the Reset telemetry menu.
The Flight persistent setting can be set for multiple timers and then these timers can be reset simultaneously with the Reset flight option.
Whenever a new model is loaded, EdgeTX will conduct pre-flight checks based on the checks that are configured on this page. If any of the checks are failed, EdgeTX will give the user an audio and visual warning that must be acknowledged before using the model. The following preflight checks are configurable:
Display checklist - When this option is selected, the model notes file will be displayed when the model is loaded. A valid model notes file must be in the Models folder on the SD card. The model notes file must be a .txt file and must have the EXACT same name as the model it is for, for example: Mobula6.txt. The text in the file is up to the user.
Throttle state - When selected, the radio will check that the throttle is at the minimum range value for the configured throttle source in the menu.
Custom Position? - When this option is selected, a number box will be shown that can be configured with a user-defined value for the throttle state check.
Switches - The section displays all the switches that are configured on the radio and allows you to select which position is the correct position for the switch state check. Selecting the switch will cycle through the available switch positions or turn the check off for the switch completely. Yellow switches have the switch position check activated. White switches e de-activated.
Pots & Sliders- When activated, this option checks the position of the pots & sliders. There are three options - OFF, ON and AUTO. When ON or AUTO is selected from the drop-down menu, buttons for the available pots and sliders will appear.
OFF - Pot and slider positions are not checked.
ON - Positions are checked against manually configured pot and slider positions that are set to active (yellow). To manually set the check position, select ON from the drop-down menu, put the pots and sliders into the desired position, and activate them by selecting them (yellow).
AUTO - Positions are checked for activated pots and sliders and compared to the last automatically saved position before the radio was turned off or the model was changed.
Center Beep - Allows you to turn on / off the center beep function for the individual sticks, pots, and sliders by selecting them (yellow).
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. 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
Further configuration settings for trainer mode can be found under radio settings,
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.
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 buttons for each flight mode. Flight mode buttons in yellow designate the current active flight mode. Selecting a flight mode button will take you to the configuration page for that flight mode.
Check FM Trims: When the check FM trims button is pressed, the trims for the current flight mode are temporarily disabled. This is used to test the impact of the current flight mode’s trims on the outputs.
The flight mode conifiguration screen has the following options:
Name: The custom name for the flight mode. If configured, this name will be shown on the lower center position of the main screen between the trims.
Switch: The trigger to enable that flight mode. It can be a switch, pot, telemetry, trim or logical switch.
Fade in: Gradually change the trim value when this flight mode is enabled. Specify the time in seconds (0.0 - 25.0) until the value change is completed.
Fade out: Gradually change the trim value when this flight mode is disabled. Specify the time in seconds (0.0 - 25.0) until the value change is completed.
Trims: Once the Setup button is selected, the trim setup screen will be shown.
To configure the trims, select the trim that you want to configure to make sure that it is turned on (yellow). Then select the flight mode (0-8) that will provide the initial trim value and modifier (= or +) from the drop-down menu.
Modifier - there are two possible value modifiers = and +. The = modifier uses the trim value directly from the selected flight mode. The + modifier uses the trim value from the selected flight mode and then adds the trim value from the flight mode you are configuring.
Example 1: If you are configuring FM1 and set the value to =0, FM1 will have the trim value of the current value of the same trim in FM0. In this case, changes made to the trim in FM1 will also affect the trim in FM0 and vice-versa.
Example 2: If you are configuring FM1 and set the value to +0, FM1 will have the trim value of the same trim in FM0, plus any trim changes made while in FM1, In this case, changes made to the trim in FM1 do not affect the trim in FM0. However, changes to trim values FM0 will affect trim values in FM1.
If the trim is turned off (white) on the Trims setup page, you will not be able to adjust it at all on the main screen.
