EdgeTX Companion 2.11.5, released by the EdgeTX open-source project, is a Windows-based configuration and backup utility designed for hobby-grade radio-control transmitters that run the EdgeTX firmware. Positioned within the Remote-Control & RC Tools category, the application allows pilots to create, edit, and organize model profiles—mixes, servo limits, flight modes, telemetry screens, and Lua scripts—offline on a desktop PC, then transfer the complete radio image to the handset over USB or SD card. Companion also handles firmware flashing, bootloader updates, and one-click snapshots of the entire transmitter configuration, making it easy to clone settings across several radios or restore a model after experiments. Because EdgeTX firmware is developed collaboratively and iteratively, the software tracks fourteen concurrent Companion releases that correspond to successive firmware branches, enabling users to stay aligned with stable, release-candidate, or nightly builds without manual hex editing. Typical use cases include competitive drone racers who need identical setups on backup transmitters, scale-boat builders who rely on complex throttle mixes, and club instructors who distribute standardized trainer profiles to students. Companion additionally reads legacy OpenTX EEPROMs, so pilots migrating to EdgeTX can import years of existing models with minimal re-work. The package is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always serving the latest version and supporting batch installation of multiple applications.
