Refer to Application Note 2 : ‘Timer – Use a Switch to Reset, Pause and Run’.
Refer to Application Note 7: ‘Use a Timer To Record Accumulated Flight Time’.
Refer to Application Note 5: ‘Control Audio Volume With A Slider’.
Refer to Application Note 3: ‘Throttle Disable with Sticky Throttle Option’.
Switch SF enables and disables the throttle as follows.
Switch SF, as well as enabling and disabling the throttle, also arms and disarms the Flight Controller via channel 5.
Note that motors arm only if all the preflight conditions are satisfied.

Six Position Switch
(Refer here for description of the 6 position switch.)
The six position switch S3 selects one of six modes. Curve CV1 converts the S3 values to the channel values required to select the correct mode in the autopilot. Channel 8 is used to set the mode.
On the Mixer screen, the following line configures channel eight.
A delay up of 0.3 seconds is used so that the switch can move across modes quickly without implementing the selected mode until the switch is in position for at least 0.3 second.
Curve CV1 creates a PWM signal for each desired flight mode that falls in the middle of each of the flight mode ranges. This table maps the S3 switch values to the flight mode values.
The Curve that maps the values of each switch position to the required % values is here.
Three Position Switch
Switch SA selects AUTO and QRTL as follows.
When switch SA is down, channel 9 = +100%, -100% otherwise.
When switch SA is up, channel 10 = +100%, -100% otherwise.
When switch SA is in the middle, both channels 9 and 10 = -100%.
On the Mixer screen, channels 9 and 10 are configured as follows.
On the Taranis radio, switch SC is used to control the geofence as follows.
Switch SC↑ is geofence off.
Switch SC- is geofence enabled.
Switch SC↓ is geofence enabled and reset.
The geofence enable channel in the Taranis is channel 7.
When channel 7 = -100%, the geofence is disabled. When channel 7 = 0 or +100%, the geofence is enabled.
The mixer controls channel 7 as follows.
CV2 is as follows.
The geofence reset channel in the Taranis is channel 6.
When channel 6 = 0 or -100%, the geofence reset is disabled. When channel 6 =+100%, the geofence reset is enabled.
The mixer controls channel 6 as follows.
CV3 is as follows.
Geofence Audio Files
Create these audio files and transfer them to the SD card folder SOUNDS / en.
Use these special functions to play the geofence files. For this example, SF11 through SF13 are used.
Check Geofence Control
In each of the SC positions, check the channel 7 value, the channel 6 value and the audio announcement as described in this table
The receiver must show the flight controller when the receiver has lost signal from the transmitter so that the flight controller can then carry out its fail safe procedure.
When the Taranis starts, it checks that the throttle, switches and pots are in the required positions.
At startup, the following conditions are set.
- throttle down
- mode switch SA in the mid position (not AUTO or RTL mode)
- 6 position switch in MANUAL
