Personally I think it is something to do with adjusting the transmitter power output.
Would make some sense given the different laws in various countries.
With that pot you can chance CE transmitter output to FCC transmitter output Wth fcc you contrle your bird over a langer distance. What output is allowed depends on the country you fly. CE is european regulation and fcc is bassically us regulation.
Yes, but only on the Vision (5.8Ghz).
It doesn't have much to do with distance or height (although they do increase - on the Vision), but rather 5.8Ghz transmitter signal strength regulations.
A 600mW video transmitter that runs on 5.8Ghz, which most of us use, is also "not legal" in some parts of the world. A 250mW usually is within regulated frequency strength limits.
Many Txs will. In the case of the Phantom, it would be financially unviable to make two different cases and two different PCB's just because of a $0.10 part (the pot), so they're all made the same, except on Non-Visions it has no functionality. Although you can turn is as much as you like.
