This is an interesting thread.

I don't yet fly FPV, although I have a model which has a camera and video downlink.

Here, in the UK, it is almost certain that long-distance FPV will become illegal as of next month (November). There will be an amendment to the Air Navigation Order which requires that the aircraft' commander keeps the model in sight at all times and is able to resolve any conflicts...that is, he must use natural, unaided vision, not binos. This is widely interpreted as meaning that the FPVer must be on a buddy lead, and that the commander (non-FPV) has the master transmitter and remains in a position to take control of the aircraft if he spots a conflict.

I'm not sure what restrictions there are in other countries.

I'd guess that most FPvers want to fly cross-country. By cross-country, I mean at a distance from which line-of-sight control is impossible or very difficult...say >500m.

I expect that most of us would agree that cross-country flying poses problems with respect to airspace infringements and other conflicts.

If we want, as I do, to be able fly cross-country legally, what case should we make to our Governments? How could we alleviate the reasonable concerns for public safety, whilst facilitating the inevitable growth of FPV? Should there, for instance, be a minimum equipment list?...or some sort of licensing scheme?...or restrictions upon size/weight? I dunno, you tell me.

Should we make any case at all, or "just do it"?

BTW, what is the AMA' stance upon FPV? In the UK, our BMFA (AMA equivalent) has proven to be quite conservative; you might almost say "anti-FPV".

AMA's rules are basically the same as the scenario you outlined.
PIC on the main controller with visual contact to model at all times.
FPV pilot on the buddy box.

Today, I was close to 4k feet UP, and probably within 500 ft radius of where I was. I know this, because I could see over the nearby mountains, and the highest has an elevation of 9600, and I'm at 6200. AND, I was using Spektrum dx6i, and an ar7000 rx. I've had really good luck with this setup at this location.
