Set failsafe
Setting the R/C failsafe parameters is a very important part of the configuration, don't skip it! You never
know when you will have problems with uplink and lose control of your aircraft.
It can go into a predefined position of the channels (position) or the receiver turns "dead" (cut) and
outputs no more signals to the servos, FC, etc. The receiver configuration for failsafe can be found in the
menu of the transmitter/Lua-script , under your particular “CROSSFIRE RX” menu and Failsafe - here you
can set "Cut" or "Position".
- "Cut" is useful when the model has a controller installed which then executes its own failsafe
routine
- "Position" is intended for all other models or when the controller expects a certain channel
position
For "Position", failsafe parameters can be set following this procedure:
Micro TX:
1. Turn on and off the transmitter and receiver
2. Move the sticks and switches to the desired position
3. Press and hold the button on the CROSSFIRE transmitter for a few seconds
4. Turn off the transmitter and check that the set position is taken
Standard TX:
1. Turn on and off the transmitter and receiver
2. Move the sticks and switches to the desired position
3. Go to the CROSSFIRE menu and select "Bind" - it initiates the failsafe process this time
4. Wait until "Failsafe set" appears on the display
5. Turn off the transmitter and check that the set position is taken
Alternatively, the standard TX can save the current position via shortcut. To do so, take the position with
the sticks and switches, push the joystick down briefly and then hold it up for a few seconds. The message
"Failsafe set" appears on the display
BST Connectivity with TBS equipment
There is an issue when you want to run BST devices like the GPS or BLACKBOX direct without a CORE PRO.
Most of the BST devices needs 5V which the CORE PRO provides. You can also power the BST line by using
the TBS 3-way splitter with a servo header to connect a 5V regulator or BEC. The CROSSFIRE RX does not
power the BST line when 5V is applied to the servo connectors.
The following explains the required power needs:
● TBS BLACKBOX - Can be powered by the BST 5V or by the Flight Controller over the ext. FC port
