Hi! Iam new to hd fpv.
I got a DJI FPV Googles v2 (not the new googles 2)

Iam rooted and installed fpv wtfos and FCC hack

however how can i switch the googles to FCC (US) mode to allow acces to all 8 channels?

If you have WTFOS installed then just install the "fcc‐unlock" package too (on both the Air Unit and Goggles), then the FCC hack will be (re)applied for you automatically at each bootup without you needing to do anything else.

Yes it is installed but in the player i se only 4 channels
and the max power is 25mw

(iam not installed for the air unit yet)

You only get all 8 channels if you use the 25Mbps mode. The 50Mbps mode only gives you 4 channels (1, 2 & 3 plus public channel 8).

With 50Mbps mode there is no room for 8 channels on the 5.8Ghz frequency band because each of the channels (with the exception of public channel 8) uses double the normal bandwidth so there can only be 4 channels.

Yeah thats true
but transmission menu is greyed out. maybe because air unit not paired yet?

The bitrate is set on the Air Unit so yes you need the goggles bound with an Air Unit before you can change that and some other settings.
