Rush Tank VTX not changing power levels via Smart Audio/ CLI

If you have been struggling to get smart audio working properly on your Rush VTX, particularly changing the power levels, the reason is most likely that the default betaflight specification for the VTX has changed. Fortunately its a very easy fix.

(excuse the non English screenshots, they are from RushFPV and I am not at my main PC to get new ones, buttons are all in the same places)

  1. First download the appropriate .JSON definition for your appropriate VTX here
  2. Connect to your FC via betaflight and go to the VTX tab.
  3. Upload a new JSON file
  4. Save the new config for your FC

Now you should be able to change everything correctly as you would expect via the OSD/CLI
