2.5. Custom RGB LED Setup
The MT12 features RGB LEDs that are user programable via LUA scripts. A basic set of LUA scripts are included with
the radio. You will be able to program any sequences of lights and aects you choose with a LUA script and can share
your scripts with other users.
The LUA scripts for RBG eects are in the “\SCRIPTS\RGBLED” folder of the MT12 SD card.
To choose a colour or eect for your MT12 you can use one of the included LUA scripts, create your own LUA script or
download a community made script and place it in the folder above.
To set one universal colour/eect turn on the RGB leds funcon in GLOBAL FUNCTIONS and choose a script.
To set a colour/eect for each dierent model turn on the RGB leds funcon in SPECIAL FUNCTIONS and choose a
script.
Advanced uses for RGB LEDS
Other than looking cool the RGB LEDs have some praccal applicaons too! A combinaon of Logical Switches and
special funcons can be used to add extra funconality to the RGB lighng system.
For example, the RGB light colour can be linked to telemetry data from the baery of the model. A voltage threshold
could be set to change the RGB colour from GREEN to RED when the baery reaches a specied voltage and the
“POLICE” eect (ashing blue and red) when the model has not been powered up yet or Telemetry is lost.
First create these logical switches:
Then setup these special funcons.
The possibilies are endless and can be customised to suit your needs.

2.6. Switch and Joysck Expansion Modules
The MT12 features interchangeable expansion modules and includes a two 2 posions switch module and a 4 way
Joysck module. You can choose the module you wish to install based on your own preferences.

Timers
Timer 1/2/3 - There are 3 congurable mers in EdgeTX. The following conguraon opons will be displayed once
the mer is no longer set to OFF:
Timer 1 [Mode] [Switch]
[Mode]: The opons include:
•OFF- The mer is not used
•ON - The mer runs all the me
•Strt (Start) -The mer starts once the congured switch is acvated. Aer the me is started, the mer
ignores the switch posion.
•THs (Throle) - The mer starts once the throle is raised and the congured switch is acvated. The mer
will stop counng if either the throle posion is lowered back to the minimum value or the congured
switch is deacvated.
•TH% (Throle %) - The mer counts proporonally to the throle. It counts in real-me at full throle and
half speed at 50% throle.
•THt (Throle Start) - The mer starts once the throle is raised and the congured switch is acvated. Aer
starng, the mer ignores the throle posion and will keep counng unless the switch is deacvated.
[Switch]- Select the switch that will trigger the mer to start. If no switch is selected, the mer will trigger based only
on the congured mode. In addion to a switch, you can also select a trim, a telemetry source (triggered when
telemetry data is received from that source), or physical acvity (sck movement or buon press) (labelled as ACT)
Those items with a "!" mark in front of the trigger name mean that the condion is reversed. For example, "!SA-"
means "when SA switch is not in middle/centre posion (= up or down)".
Name: Name of the mer
Start- The me used for the mer's advanced funcons. The default value is 00:00 and when le as such, the mer
operates like a stopwatch, counng upward unl stopped. If a dierent me is entered in this box, then the
addional eld will appear next to the me with the opons: Remain or Elaps.
If set to Remain, the counter will funcon like a countdown mer - counng down from the designated me to zero
and then alerng the user. If set to Elaps, the mer funcons like an alarm, counng up from zero unl the
designated me and then alerng the user.
Persist (Persistence):
•O - The mer value is reset when switching models or when the radio is turned o / on.
•Flight - The mer value is NOT reset when switching models or when the radio is turned o / on. The mer
value is only reset when the Reset ight opon is selected in the Reset menu.
•Manual Reset - The mer value is reset only when it is individually selected to be reset (example: Reset
mer1) in the Reset menu.

Minute (Minute Call) - If selected, you will be noed every minute that passes as described in the Count Down
opon.
Count Down:
•Silent - No nocaon is given unl the mer reaches zero. When it reaches zero, you will hear one beep.
•Beeps - The radio will beep every second starng at the me designated.
•Voice - The radio will count down by second starng at the me designated.
•Hapc -The radio will vibrate every second starng at the me designated.
Trims sengs

E.Limits (Extended Limits) - When enabled, it increases the minimum and maximum range for the output values to -
150 and 150. Extended limits are necessary if the full range of the control surface cannot be reached with standard
limits.
E. Trims) Extended Trims: Increases the maximum trim adjustment value from ±25% to ±100%.
Reset - This resets all trim values to zero.
Show trims: When set to Yes, it will display the numerical trim value on the trim bar. When set to CHANGE, it will
display the numerical value once the trim is no longer at zero.
Trim Step: Denes 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%
•Exponenal = 0.2% near the centre and the step value increases exponenally as the distance from the
centre increases.
Throle Sengs
Throle
The throle related conguraon opons below are displayed in collapsible menu.
T-Reverse: When enabled, this opon reverses the output direcon of the congured throle channel.

T-Source: The source that will be used for the throle.
T-Trim-Idle: When enabled, the throle trim will only aect the boom poron of the throle band.
For example, with Trim idle only enabled, the throle sck at the lowest point might have a value of -80 and the
center point will sll be 0 and the highest point of 100. Without this enabled, the throle sck at the lowest point
might have a value of -80 however, the center point will be 20 and the highest point of 100.
T-Trim-SW: The trim switch that will be used to trim the throle. It is possible to substute the throle trim switch
with the aileron, rudder, or elevator trim switches.
Preight Checks opons
Preight Checks
Whenever a new model is loaded, EdgeTX will conduct pre-ight checks based on the checks that are congured 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 preight checks below are displayed in collapsible menu.
Checklist - When this opon is selected, the model notes le will be displayed when the model is loaded. A valid
model notes le must be in the Models folder on the SD card. The model notes le must be a .txt le and must have
the EXACT same name as the model it is for, for example: Mobula6.txt. The text in the le is up to the user.
T-Warning - When selected, the radio will check that the throle is at the minimum value for the congured throle
source in the T-Source conguraon opon.
Cust-Pos - When this opon is selected, the value designated in POS.% will be used for the T.Warning.
Pos.% - minimum value of the throle for the throle warning when Cust-Pos is enabled.
S-Warning - The secon displays all the switches that are congured on the radio and allows you to select which
posion is the correct posion for the switch state check. Selecng the switch will cycle through the available switch
posions or turn the check o for the switch completely.
Pot warn- When acvated, this opon checks the posion of the pots & sliders. There are three opons - OFF, ON
and AUTO. When ON or AUTO is selected, buons for the available pots and sliders will appear. To enable the Pot
warning for an individual Pot, select the pot with the [roller] or [dial] and click the buon to highlight it. Highlighted
pots are enabled.
•OFF - Pot and slider posions are not checked.
•Manual - Posions are checked against manually congured pot and slider posions. To manually set the
check posion, select manual the from menu, select the item that you want to set, and long-press the
[Enter] buon to set its current posion for the check.
•AUTO - Posions are checked for pots and sliders and compared to the last automacally saved posion
before the radio was turned o or the model was changed.
Ctr Beep - Allows you to turn on/o the centre beep funcon for the individual scks, pots, and sliders by
highlighng them with the [roller] or [dial] and pressing the buon. When a switch is highlighted, the funcon is
enabled.

Glob. Funs - When enabled, global funcons programmed in the radio sengs will apply to this model. When
disabled, global funcons will not apply to this model.
ADC Filter - Enables/disables the ADC lter for this model. The global opon will take the value designated in the
radio sengs, which is on by default.
The ADC lter is a lter for the proporonal channels (scks, pots, sliders), smoothing out smaller fast movements
that occur due to noise in the system electronics. Normally, this lter should be disabled for models with ight
controllers.
Internal / External RF
The conguraon sengs for both the Internal and External RF secons work the same. The only dierence is that
the Internal RF secon is for conguring the built-in module and the External RF secon is for conguring an RF
module in the external module bay.
The conguraon opons are: o or the module name of the installed module as congured in the Radio sengs.
Conguraon opons are unique to each installed module. Please consult the manufacturer's documentaon for
conguraon opons.
Conguraon opons for the mul-protocol module are described here: hps://www.mul-module.org/using-the-
module/protocol-opons
Receiver number - A receiver number is a user-assigned number for a model that is sent to the receiver when bound.
Each model must have a unique receiver number. However, models using dierent 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 eld.
If using the radio in gamepad mode, both internal and external RF modules should be turned o. This will result in
increased performance when connected to a computer via USB.
Trainer
Trainer Mode - The Trainer Mode opon is where you can congure 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 dierent use cases, such as: connecng a head tracker, Instructor / Student training mode, and controlling
complex models that require more sck inputs than available on a standard transmier.
Master mode - This is the mode for the radio that will be connected to the model. This radio also shall congure the
special/global funcon (Trainer) to acvate the passthrough mode. When the passthrough mode is acvated, 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 possible conguraon opons:
•O - Trainer mode is not used for this model.
•Master / Jack - Master mode using a cable connecon.
•Slave / Jack - Slave mode using a cable connecon.
oChannel 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.
oPPM Frame - The rst eld is the length of the PPM frame. The second eld is the stop length/delay
between pulses. The dropdown is to select the polarity of the signal. The frame length is
automacally adjusted to the correct value when the number of transmied channels is changed.

However, this automacally assigned value can be manual changed. Note: In most cases, the default
seng does not need to be changed.
•Master / Bluetooth - Master mode using a Bluetooth connecon (if installed in radio).
•Slave / Bluetooth - Slave mode using a Bluetooth connecon (if installed in radio).
•Master / Mul - Master mode using an addional externally mounted Mul-protocol module for the
connecon. For more informaon on this setup, see Set-up wireless trainer with a Mul -protocol module
Enabled Features opons
Enabled Features
The Enabled Features secon allows you to congure which pages are visible in the selected model's radio setup and
model sengs area of EdgeTX. The page names are displayed in a collapsible menu with the following congurable
opons:
•Global - When selected, the tab will take the global value congured in the Enabled Features area in Radio
Setup. The congured global value will display next to the opon.
•On - When selected, this tab will be visible when this model is loaded.
•O - When selected, this tab will not be visible when this model is loaded.
Note: Turning o a tab only hides the tab and does not change the items already congured in that tab. For example,
if you congure a special funcon and then turn o the special funcons tab, the special funcon will sll work as
congured.
EXCEPTION: Turning o the Global Funcons tab will disable congured global funcons for that model.
USB Joysck advanced mode sengs
USB Joysck
The USB Joysck has two possible modes, Classic and Advanced.
In Classic mode, the radio's congured output channels will be sent to the target device in numerical order and
mapped to the device's precongured USB controller axes and buons. Below is the default channel mapping for
Microso Windows.
•Ch1 - X Axis
•Ch 2 - Y Axis

•Ch 3 - Z Axis
•Ch4 - X Rotaon
•Ch 5 - Y Rotaon
•Ch 6 - Z Rotaon
•Ch 7 - Dial
•Ch 8 - Slider
•CH 9 - Ch 32 - Buons 1 - 24
In Advanced mode you can congure the following addional opons:
If mode (Interface mode): This indicates to the target device (the device you are connecng your transmier to)
what type of device you are connecng. The opons are Joysck, Gamepad, MulAxis.
Note: Currently there is a limitaon in MS Windows that may limit your transmier to being only detected only as a
Joysck, regardless of what is selected in this opon. In MacOS, Linux and Andriod this funcons properly.
Circular cutout: For axis pairs (X-Y, Z-rX): By default, the range of the axis pairs is a rectangular area. With this opon,
the axis will be limited to a circular area (like gamepad controllers commonly are). Opons are : None or X-Y, Z-rX or
X-Y, Rx-Ry
Channel Sengs
Mode: For each output channel, you can select the mode that you want to use for that channel. The available
opons are None, Btn, Axis, Sim.
None - Channel is not used
Buon mode opons for a selected channel
Btn - Channel is used to simulate a buon. Conguraon opons include:
•Inversion - Inverts the output channel signal. Opons are: On / O
•Buon Mode -
oNormal - Each posion of a mulposion switch is represented by a buon. The current switch state
is represented by a connuous buon press.
oPulse - Similar to "Normal" mode. However, instead of connuous buon press it is represented by a
short buon press.
oSWEmu - The toggle switch emulaons a push buon. The rst press turns the virtual buon on, the
second press turns it o.
oDelta - The change of the output channel is represented by 2 buons. While the output value is
decreasing, the rst buon is pressed. When the output value is increasing, the second buon is
pressed. If there is no change, then no buons will be pressed.
oCompanion - This opon should be selected when using your transmier to control the simulator in
EdgeTX Companion. It allows the mul-posion switches to funcon properly in the simulator.
