You can now change your Betaflight settings, such as PID, rates, VTX settings etc at the field from your Taranis using LUA script.

Here is a tutorial how to do it:

This protocol no longer works - I followed these instructions. I'm using opentx -X9D+ version 2.3.11

You will also need a receiver with telemetry support and also telemetry enabled in Betaflight Configuration tab.
