The .pdf is actually sort of interesting. Not something that will get you put on a list, but rather, it's by the people who make the lists, describing how some of the people on their lists got there.

> I would have to imagine it was larger than a quadcopter, and I guarantee you it was nothing like a quadcopter from how long it was up - it has to be satellite-driven because there’s no line-of-sight, there’s no cell phone coverage that could have dealt with that, so it has to be satellite-driven, which is pretty freakin’ sophisticated.” So, setting aside this claim that there’s no line of sight, my bet is these guy…

Assuming that the story is true, the thing that rules out a traditional quadcopter is the fact that it was flying for an hour. You can make quads fast or long range/endurance, but AFAIK, nobody is even close to making a quad that can do 100mph for an hour. The battery weight for that kind of flight time would be too heavy for the quad to fly.

My bet is something like a large scale RC plane with no real time video link. The tech is already here:

1. Gas engine would allow for >1 hour flight times

2. Flight management systems like Ardupilot means it could have been flying a pre-planned mission with little/no real time control. The helicopter pilots may have been mistaken thinking that it was reacting to them at all.

3. Or maybe it was reacting: two way radio links are nearly trivial with low enough bandwidths. The controllers could have been monitoring the ATC picture and had the RC plane also reporting telemetry. When the police helicopter got close they may have inserted waypoints into the flight path of the RC plane to make it fly away.

There are thousands of serious RC hobbyists in the USA alone that could make something like this. Most of them follow the rules, but I wouldn't put it past a drug cartel to pay/coerce someone to make one for them. Maybe foreign spies, but I think that's unlikely considering Davis-Monthan AFB doesn't have any interesting research or test units. The Chinese wouldn't smuggle in a RC plane to watch A-10s or F-16s training in a MOA.

Earlier quoted context omitted.

Why even use drug mules if you can just drone everything over the border?

Their carry weight is absolute shit and ferrying over 10 doses isn't really worthwhile

Unless you have a thousand drones. If any one drone gets taken out then you just lost a negligible quantity of product. If a traditional mule is caught you lose millions. A single bust would pay for a fleet of drones.

You can use a gas engine to hit that kind of time in a quad. There aren’t any great options on the market right now, but as a DIY project it’s not that difficult to use an engine to charge the batteries in flight.

I wouldn't say it is impossible.

A (relatively) simple solution would be to use something with more dense power source, maybe fuel. RC enthusiast use fueled engines routinely, it isn't something special. There are various types of advanced fueled engines for RC use from traditional 2-4 stroke miniaturized engines to turbofans.

They are not very common on small quadcopters because of lack of response. Quadcopters depend on an onboard controller for fast corrections and for this to work you need a motor that can react very fast and precisely. A liquid fuel engine in a craft that does frequent changes in direction of g forces is not an easy thing to control precisely.

But this could be easily remedied by making this at least partly hybrid (use engine to charge small battery and use this to power additional motors to improve response to help stability and maneuvers).

Saw some guys racing drones like the first video in a local park. Every bit as fast and maneuverable, but they had them going through 6 ft gates on a course roughly the size of a football field. I assume they're not really human-controlled because I could barely track where the drone was, let alone give it precise controls for how to pass through the gate. Went home and told my wife "If we ever get into a war, humani…

I fly FPV drones.

The idea they are not human controlled is absurd.

They handle like nothing else. There is literally nothing else to compare them to so they seem almost alien. You could dive bomb a gate yourself after maybe 10 hours of practice in a simulator.

Of course the first time you try you won't even be able to keep the drone in the air but really quickly the controls become second nature.

The irony is the guys at the park were most likely not even great pilots. Look up Mr Steele on youtube if you want to watch someone do really inhuman stuff.

You should learn Tor

And a sand box program like Sandboxie

If you are worried about tracking (like the PDF pinging back with a zero day) you'll have to look at Sandboxie's internet restrictions.

Or use something like Tails which does everything.

I won't link these because you need to do your own research to find what you want.
