RadioMaster MT12

• Min - Denes the minimum that is allowed for the global variable.
• Max - Denes the maximum value that is allowed for the global variable.
• Popup - When enabled, a pop-up window will be displayed on the main screen when the value of this global
variable changes during normal use.
• FM1 -> FM8 - Allows you to select the global variable inheritance for the Drive mode. Long press the eld to
switch between Own and Inheritance mode. In Own mode, you can dene the global variable value for the
selected Drive mode. In Inheritance mode, you can select the Drive mode that the global variable will inherit
the value from.
3.3. Fail Safe
4in1 Mul-Protocol Failsafe
Failsafe sengs determine what the receiver will do if radio communicaon is lost. The receiver is congured using
sengs sent from the radio as part of the radio transmission.
Conguring failsafe sengs ensures that the receiver behaves in an expected way if radio communicaons between
the radio and receiver are lost, for example by reducing throle to -100%, or acvang a return-to-home (RTH or
RTL) funcon in the ight controller.
Dierent receiver types require dierent failsafe procedures, further informaon: hps://www.mul-
module.org/using-the-module/protocol-opons#failsafe
ExpressLRS Fail safe
Once the receiver is bound and the model has been correctly setup on the radio open the ExpressLRS LUA script by
pressing the [SYS] Buon and using the roller to run the ExpressLRS script.
Once the script is loaded use the roller to scroll to “> Other Devices” to open the receiver sengs. Scroll to “[Set
Failsafe Pos]” and press enter on the roller. The posion of the trigger, wheel, knobs, switches, joysck will now be
recorded as the failsafe posion on the receiver.

Receiver Behaviour
Not Set
Failsafe not configured.
Hold
Hold the last values received before radio
communication was lost.
Custom
Use the radio to configure specific values for
the receiver to use.
No Pulses
All channels go to their minimum values.
