1. The Installation Path
LUA scripts live on your Radio's SD card. If they aren't in the exact right folder, your radio won't "see" them.
SD_CARD (Root)
└── SCRIPTS
└── TOOLS
├── elrsV3.lua
└── bf.lua
Tip: Most modern radios like the RadioMaster Pocket or TX16S come with these pre-installed. Only update them if you update your firmware.
2. The Big Three
ExpressLRS
/elrsV3.luaAdjust packet rates, telemetry ratio, and transmit power (mW) on the fly.
Betaflight
/bf.luaChange PIDs, Rates, and VTX channels from your radio screen.
TBS Crossfire
/crossfire.luaThe original long-range config script for Team BlackSheep hardware.
3. Troubleshooting
"Loading..." Forever
This usually means your radio and drone aren't talking. Ensure the drone is powered on (plug in a battery) and that Telemetry is enabled in the Betaflight Configuration tab.
Script Syntax Error
Usually happens when the LUA file version doesn't match your Radio's OS (EdgeTX/OpenTX). Re-download the correct version from the official GitHub.
