Setup
LEDs Status
LED Flash Codes for Channel, Band and Power
The FuriousFPV Stealth Race VTx signals selected channel, band and power levels using a
startup sequence of LED codes. The same sequence is also repeated in the menu to make it
unified. First the RED LED flashes to indicate the item being shown. One flash for channel,
two flashes for band, three flashes for power level. Subsequently, the BLUE LED will indicate
the value.
RED LED
Indicate item –Channel, band or power setting
Blue LED
Indicate value
For example, Channel 2, Band B, Power of 200mW, will have the following startup
LED code:
1x Red and 1x Blue = Channel 1 => Channel 2
2x Red and 5x Blue = Band Race (C) => Band R (C)
3x Red and 2x Blue = Status 2 => No power
4x Red and 2x Blue = Power 2 => 200mW
Code LED Status: Status 1 –Pitmode, Status 2 –No Power, Status 3 –Normal

Option 3: Configure FuriousFPV Stealth Race VTx by
Transmitter Taranis
You can now adjust rates and VTx settings right from your Taranis menu with Betaflight
using LUA script and Smart Port. In this tutorial we are going to show you how. Furious FPV
uses this article written by Artur Banach, Oscar and editted by Furious FPV. This guide is
written specifically for Betaflight firmware - Fortini F4.
Hardware Requirement
Taranis X9D or QX7 TX
Furious FPV SPD15 or XSR RX (Smart Port required)
Fortini F4 Flight Controller with Betaflight FW, find out if Smart Port is supported
natively.
FuriousFPV Stealth Race VTx –to change VTx settings from Taranis
Hardware Connection
To allow VTX configuration from Taranis, simply connect S.PORT from SPD15 or XSR RX to
UART TX6 pin on the Fortini F4
For changing VTx settings, Telemetry port from FuriousFPV Stealth Race VTx also needs to
be connected to one of the UART TX4
Please connect as below picture:

Update Taranis OpenTX Firmware
Your Taranis TX has to be updated to the latest OpenTX firmware (we tested V2.2 RC14
successfully). The process is simple, and it’s covered here:
https://oscarliang.com/flash-opentx-firmware-taranis/
Download LUA Script for Betaflight
The LUA script for Betaflight can be downloaded here:
https://github.com/betaflight/betaflight-tx-lua-scripts/releases
Please be aware that the LUA script files are different for Frsky X9D, QX7 and the Horus.

17
Download the latest version available for your transmitter model.
The zip file contains 2 folders: BF and TELEMETRY, and the files needs to be copied to the SD
card in your Taranis.
1. Copy BF.lua file in TELEMETRY folder to the /SCRIPTS/TELEMETRY/ folder in your
Taranis SD Card.
2. And copy the whole BF folder to /SCRIPTS/ folder in the SD card. These are the script
interface files needed to make it work.
Betaflight Configurator Settings
First of all, make sure SmartPort is setup properly:
1. In Betaflight configurator, PORTS tab, find the UART where you have connected S.PORT
to, then select SmartPort as the Telemetry Output
2. Enable option TELEMETRY in Configuration tab
Extra Steps for VTx setup
Go to PORTS tab, find the UART4 you connected the VTX to, and choose which VTX you have
under Peripherals is IRC TRAMP [Auto]
With Fortini FC I am using SmartPort in UART6, FuriousFPV Stealth Race VTX in UART4
please select IRC Tramp, and SBUS in UART3.
Don’t forget to hit “Save and Reboot” when you finish.
Setting up LUA script on telemetry page
We are almost there!

18
Once you have SmartPort set up, and you have copied the BF.lua file to
/SCRIPTS/TELEMETRY/ folder on the Taranis SD card, we can proceed to the final step.
Go to page 13 DISPLAY in your Taranis. Here you can configure which telemetry screen to
execute the LUA script. In Screen 1, choose Script as the first option, and then select the BF
Lua script in the 2nd option.
You should be able to activate BF LUA script now by holding down the PAGE button (LUA
script is triggered by entering Telemetry Screen 1).
Page 1 of the script is for VTx settings.
After making VTx setting changes on your Taranis, you can save it by long pressing the
MENU button.
That’s it!! I hope you enjoyed it, and have fun changing VTx channels from your Taranis in
the field! :)
