Can't remember what it is. The 1000mw wireless system would give you more range than the 500mw but like he said, it's Dependant on antenna's setup, tuning etc.

Status: offline 		First of all, that is all garbage...the numbers you are spouting.

A 500mw unit cannot get over a mile without special directional antennas (not the ones sold with the kit thats for sure)
Dipole TX/ patch RX antennae.

Much more power than that requires a HAM radio license, but then we are regulated against "beyond visual range" by the FAA and others.

There are threads on some of the forums which mention some of the high powered amps available for both TX side and the RX side of the equation which allow phenominal range boosts. Very pricey.

Flying out to 35 miles sounds more like a UAV with GPS guided autononmous flight, not one with real-time video downlink..

Status: online 		Uh sgt rick have you seen any of the video's steve molmer or eagle something... they have flown 35miles via video. As for the 8 miles, I'm sure range video used a patch antenna, still that's all they did. No modification to increasing power output etc.

Take a look at rangevideo.com or some of the other long range video sites.

As for the "beyond visual range", this is becoming an outdated policy with the new range of video cameras and ability to control airplanes at extreme ranges. It should be changed to in control.

Status: offline 		I currently own quite a bit of equipment from rangevideo.com, so I am aware of both their stated specs and actual use.
I am very aware of FPV flight and different record breaking flights.

I don't know where you got the inpression this was somply outdated policy... it's the law.

As to the FAA and Transport Ccanada regs, I worry they are becoming more restrictive at the moment.

Govt does not trust any R/C aircraft flying without direct line of site... pending legislation is in fact going to make that even harder.
Even as the use of UAVs has increased exponentially in the military, hobby use is being legislated out and commercial use is being carefully restricted and licensed.

I subscribe to DIYDrones.com as a site where fellow flyers and experimenters work to economically increase range to unlimited, but hope the Feds don't come knockin' some day.

Status: online 		I do believe this is an outdated policy, when was this made? People flying by video would have the same control as watching from the ground if not more, I find it's easier than flying by the ground because if the plane gets small enough, regardless of wether you meant to go to your limits, you could lose the plane and control. Yes there is an added risk that something could fail but so could the radio. I don't believe they had thought about flying by video when they installed this policy.

Its the law now but it should be changed to reflect changing times. Laws are not written in stone, but evolve and change. As for the states changing their policy, they are crazy and overzealous with the security since 9/11 and yea I could see them getting more restrictive. Hopefully Canada does not follow suit for a hobby.

Ivan.

That the paranoid US environment since 9-11 will spill over to Canada.

Status: offline 		Regardless of whether the policy is outdated or not, I am simply uncomfortable with the idea of flying a device capable of killing someone. Lets assume that you decide to fly it outside of visual range, what happens when your video link fails? Even if you are flying with a telescope of binoculars you could still prevent catastrophe. But, if you are on the back-side of hills or mountains who know what's on the ground under your lawn-dart?

Don't get me wrong, I'm very excited about UAV's! I even just bought the circuit boards and parts to make the paparazzi autopilot.
Also, I'm not a fan of ridiculous laws or the explanation "it's the law," but in this case it's just common sense.

Cheers

Status: online 		What if you misjudge flying and manage to fly over people or cars(depth perception only works so far and well), or say if your at a field and receiver goes wonky on you and plane flys into crowd of people. Or say you forgot to charge a battery and mid flight you lose all control, how does this law of flying by sight have prevented that?

If your uncomfortable with flying a device that can kill someone don't drive a car, don't drive anything for that matter or if your really worried shrink your plane down to something that you can club someone over their head with, and they just ask you what you think your doing. There's a risk with all this stuff. Video could cut out, perhaps some previous damage finally takes it's toll and your plane goes crashing down. Who knows...

Point is we more or less have a perception of control, but that is not always the case. I don't see a difference between flying by video and sight because you have similar control over the situation. I am personally more comfortable flying by video because it's more natural. On top of that, much more fun, essentially your not restricted to a certain area, you can fly over rivers, trees etc, adds more excitement to an already interesting hobby.

Ivan.

I am also really excited about trying first-person video, but I will do it with a safety pilot.

My point is this: What is the point of multiplying the points of failure because you want to say "I flew my plane 35 miles?"
