Like I just said! Get in line behind me!

Here's hoping private pilot ground school covers most of the test.

Flying drones from the Us with 10 day aloft capability, to any point on the globe for 24/7 surveillance is game changing.

How long until they're flying over every major US city?

They might, but we could vote them down and likely would. But they would not be much of a threat compared to the ubiquitous cameras all over the place. For instance, if you pass my place, be sure to wave and smile. One of the new IP cameras will catch you.

Hey, GIThruster, I saw that ... I said wave, and that doesn't mean one finger!

Worse, the cameras are on a FLIR cloud service, which means The Machine and Samaritan can hack into them.

But at least I caught the guys who have been stealing our newspaper.

The UAVs will be able to tell how many of us are bald.

Cruising LinkedIn just now I finally broke the code on something an old business contact has been up to. The former CEO of the UAV controls company I used to work for recently got a job at Google. There I was thinking he was working for the project wing at Google, but that should read Google "Project Wing", their proposed UAV package delivery service.

I've probably mentioned Dave Vos here before. He's an MIT wunderkind, an import from South Africa, and a guru in using low-cost MEMS sensors to make UAV control systems. His graduate project was an autonomous unicycle of some notoriety. His main contribution is utilizing Kalman filters to work drift problems out of the sensors, essentially making them self-calibrating, so that low cost sensors can do the jobs that it used to take a million dollars worth of ring laser gyros and precision accelerometers to do. In other words, it is the tech behind all these low-cost UAVs presently on the market.

Dave has been working on the problem of making UAVs work "in the system" for some years, and thinks he knows how to make them work compatibly with the rest of air traffic control.

It'll be fun to watch. The guy is a bona fide visionary, but there are practical limits to how useful this tech can be. Personally, as a bicyclist, I kinda lean toward bicycle couriers, but that's because I have fanasized about actually doing it.

Pay = terrible
Exercise = outstanding
Hell < working conditions < Heaven (depending on weather and traffic)

A video by a friend of Bob Parks (mentioned earlier) is a bit cut off, but he points to his $33 quadrotor, and a couple more prices roll off his tongue including $16, apparently for the camera. Something cost $60 but I could not tell what. Maybe the controller? Looking up $33 quadrotor I found the link above.

https://www.youtube.com/watch?v=w2D1qe5EANw

I doubt it is a GPS camera platform, though, and it will take skill to fly it. But at that price you could carry a bunch of them so that when one crashes you just pull out another. It does have MEMS gyros, so it is not totally manual control.

Bob said he has had some time with the DJI Phantom and says it is pretty good for the price. Around a thousand bucks gets you one with a fairly good camera. This is rigged for reasonably precise programmed flight. I would not want to try stunts with it, but for something that can climb to 100 ft, hover autonomously, photograph the site, and return to a designated landing site, not too shabby. They have another in the $3k range for the well-heeled. Not bad if you can find paying work for it, and not prohibitive to learn to fly on an amateur basis while waiting for the proposed rules to become actual rules.

One particular configuration of the DJI Phantom 2 that looks promising. This is rigged to transmit video via BlueTooth and Wi-Fi, and there are range boosters available for it.

This is the kind of stuff I really love and would buy if I had the time to play.

http://tx-ready.com/txr-aircraft.html#hadronanchor

It was always an annoyance to me that so many RTF's come with the TX when you really just want one TX and set it up for half a dozen planes. These planes come with no TX so you can do that.

The Hadron has thrust vectoring--something I had planned to build into a brushless and carbon fiber reinforced Wattage TurboVector but never got around to. As the cameras TX kits shrink in size, I'm sure you'll see them in these more conventional designs. Piloting from the viewpoint of the plane is going to become common over the next few years and you'll see next gen TX with nice displays built right it. And if you have the skill to pilot it, a drone that flies 100-200mph is much more survivable in a battle zone than one that hovers. So these skills have real world uses.

Most of the old VHF systems were not true "proportional" in that the control surfaces actually corresponded to the positions of the sticks on the TX. The newer microwave systems are supposed to be vastly superior, and even the older ones 7 years ago were reportedly much better than VHF. And this is why I like one TX, because if you're not buying them over and over, you don't have to haul them around and you can put several crystals into the better models, then switch channels with a switch, one channel for each model you fly. Put vid aboard that kind of system and they'll be charging $1,000 them again.

Tablets, at least you have the advantage of a nice sized screen and some of them are cheap as dirt.

Not sure though, the advantages between a traditional stick on a TX and a tablet. Could be the tablet is even easier. If you can hold it in one hand and fly it with the other, that is an improvement. I always had to wear a strap around my neck so I could use both hands without dropping the thing. Could be with a tablet you can fly with two fingers right on the screen that gives you the view. That would be cool!
