Getting Started 3.0 Documentation

The important stuff

• Arming must be on AUX1 for safety and feature reasons, having this fixed allows us to maintain small packet sizes and deliver better aux channel options
  
• Be sure to flash both the TX and RX.
  
• Lua script MUST be updated to elrsV3.lua and is backwards compatible with 2.x. Firmware get it here: Lua
  

Compatibility

This is a patch version release bug-fixes only (mostly) and is compatible with V3.X.

Who should update from V3.3.0?

• LBT users
  
• Users with radios that are limited to 400kbaud and Lua freezing at the loading screen
