Regarding point (B), I've never had a problem with the integrity of my 2.4Ghz control system, in spite of the local traffic on that band. I guess it's because it's frequency hopping system, which is fairly robust, right? And I don't know anybody who uses UHF for conventional non-FPV aircraft because it is more robust that 2.4G.

So for me, I still don't see why you would want to use UHF unless you are planning to fly further than you can on a 2.4G system. It's a shame we're not permitted to do so, because to me, that is the exciting possibility of this technology. I can see why we have these laws, but I feel it's really a case of being sensible and managing the risk you are taking. For example, what about if you go to the middle of Dartmoor and fly beyond visual range there? Is that still illegal?

And another thing, I reckon the 'visual range of a spotter' thing was a concession on article 166 of the Air Navigation Order. However, if you put a GoPro camera on the front of your plane in addition to a piloting one, does that not make it a 'Small Unmanned Surveillance Aircraft', which is then subject to article 167 of the ANO, and is not subject to such restrictions?

Sorry for all the questions. I don't intend to break the law. It just doesn't seem that clear to me.
Dont get too worked up bw459205 it's a fact that many UK FPV'ers dont follow these rules. If we did we would be severly restricted. Just be sensible about it and use your common sense.

I'm not talking about using UHF for FPV non-fpv flight. That would be pretty silly. I have had plenty of issues using 2.4ghz for rc in a suburban area. On my first FPV flight my trex 250 spooled up by itself and flew into a bush! Clearly something nearby was blasting on 2.4ghz but go figure I was using a spektrum rc tx which is not highly rated here. I have had a couple of other scary moments too. I never want that kind of thing to happen again so I'm hoping my recent move to UHF will prevent this in the future.

It may be different for others too but I like to make sure my rc link has more range than my video so that when my video starts to recieve static I can still control my FPV platform! Its better for your video to start showing the limits of your range rather than your platform suddenly kicking into failsafe and being unable to head back home! Its one of TBS's philosophies.

I recommend you read this if your confused:

If you really want to get into discussion about it I recommend you go on the fpvuk forum to discuss with Simon and the other guys that know far more about FPV legalities than probably most do here.
