Download: Opentx 2.1.9
FrSky historically hosted OpenTX binaries for their radios. Navigate to frsky-rc.com → Support → Downloads → Legacy Products. Be aware that FrSky sometimes labels OpenTX as "Firmware for Taranis" without the proper version number, so double-check you are grabbing 2.1.9.
OpenTX is managed by a desktop app called Companion. Version 2.1.9 requires Companion 2.1.9. You cannot use the modern Companion 2.3.15 to flash a radio to 2.1.9—the file structures changed significantly.
Unlike modern versions available via the OpenTX Companion auto-updater, version 2.1.9 is no longer listed on the official front page. You must use the OpenTX GitHub archives or the official OpenTX Releases page.
Downloading OpenTX 2.1.9 is a time capsule trip. It is stable for what it is, but I strongly recommend upgrading to EdgeTX (the modern fork) or at least OpenTX 2.3.15 immediately after you retrieve your old data.

As of now, OpenTX 2.1.9 is a legacy version (released around 2016). The OpenTX project has since moved to EdgeTX (the modern successor) or much newer OpenTX 2.3.x.
However, if you specifically need OpenTX 2.1.9 for an older radio (e.g., Taranis X9D, X9D+, X9E) or to maintain compatibility with old setups, direct downloads are no longer available on the official OpenTX website (they only host the latest 2.3.x).
Here is the best way to obtain OpenTX 2.1.9 safely:
To actually flash 2.1.9 to your radio, you need Companion 2.1.9, not the modern Companion 2.3.
