Have you tried putting a text file called ```naco.txt``` in the SD root, containing only the number ```1``` (to set to US mode?)

I see you state that you have not powered on or setup your Caddx Vista.  Is it possible that you can't change these settings unless the goggles are bound to a powered up vista or air unit?  I have not personally tested that yet, but that might be your issue.

@5zero7rc, yes it is possible that the goggles need to bound with the Vista or air unit. But right now I do not have the supplies to test that, and am trying to get verification if this is so.

@Kralc, I'm in the US, and it has 8ch, so I believe its already in US mode. But yes, I did add the naco.txt file with 1 within the txt file.

* 2S 3000mAh battery
* `.txt` file on sd card `narco_pwr.txt` with `pwr_2` attribute in txt file

You won't know if the "hack" has worked until you also have a Vista or Air unit bound to the goggles.

As a quick test, I powered up my goggles and left everything else off. If I go to where you can adjust the power output it only shows 25mw and is grayed out.

As soon as I power up the rest of the system and the goggles connect to my air unit, I can change power output and other settings. There are a number of options that require the air unit or vista to be powered on before you can change them. I assume that information must be stored on the air unit side, not in the goggles.
