During the World Cup slalom skiing championship on Wednesday, ski champion [Marcel Hirscher] was nearly hit by an out-of-control camera drone, that crashed just behind him while filming during a run. Watch the (scary) video embedded after the break.
According to this article in Heise.de (Google Translate link), the pilot was accredited and allowed to fly the quad, but only over a corridor where no spectators were present. After the first couple of runs, apparently the pilot went off course and quite obviously lost control of the copter.

A Japanese protester flew a quadcopter with a symbolic amount of soil from the contaminated Fukushima region onto the roof of the Prime Minister’s office in April. Although it was a gesture, it alerted the Tokyo police department to the potential need to be able to pull drones out of the air.
Simply shooting them down won’t do — think of the innocent bystanders on the ground subjected to a rain of quadcopter parts. The Tokyo police’s solution: catch them in a net, flown by another quadcopter, of course.
We can’t embed it here, but go click through to the video. It looks like the police are having a really good time. How long before we see drone-net sets under the Christmas tree, or quadcopter-tag leagues? We’re uncertain of how far the Battlebots in the Sky movement got.
We have no shortage of yahoos driving quadcopters in the States, of course. From interfering with fire-fighting aircraft to simply flying too close to commercial airplanes, people are doing things that they simply shouldn’t. We’ve been covering the US government’s response that finally culminated in the FAA making rules requiring medium-weight drones to be registered. Watch our front page for more on that next week. Fly safe, folks.
[via The Verge]
The US Department of Transportation and the FAA have just released their guidelines that require registration of Unmanned Aerial Systems. This is the regulation that covers model aircraft, drones, quadcopters, and flying toys of all kinds. These rules have been anticipated since last month to be in place for the holiday season.
As expected, the FAA is requiring registration for all aircraft, regardless of being ‘model’ aircraft or not, weighing more than 250 grams (0.55 pounds) and less than 55 pounds. The maximum weight is a holdover from previous regulations; model aircraft weighing more than 55 pounds were never really legal without a permit. It should be noted that anyone can build a quadcopter with cameras and video transmitters weighing less than 250 grams. These quadcopters are not ‘toys’ by any means, but are not required to be marked with a registration number and the pilot is not required to actually register. As expected, most rules governing the actual flight of these aircraft remain in place – don’t fly above 400 feet, don’t fly within five miles of an airport.
Registration is by pilot, not aircraft, and costs $5. A registration number must be put on every aircraft the pilot owns, and penalties for not registering can include up to $27,500 in civil penalties and up to $250,000/3 years imprisonment in criminal penalties. The full rules are available in this 200-page PDF. As with most government regulations, there will be a 30-day RFQ period beginning December 21st on regulations.gov. The docket number is FAA-2015-7396.
Here’s something that isn’t quite a hack; he’s just using a 3D printer as a 3D printer. It is extremely interesting, though. Over on Hackaday.io [Anton] is creating 3D printable propellers for quadcopters and RC planes. Conventional wisdom says that propellers require exceedingly exacting tolerances, but [Anton] is making it work with the right 3D file and some creative post-processing treatment of his prints.
These 3D printed props are a remix of an earlier project on Thingiverse. In [Anton]’s testing, he didn’t get the expected lift from these original props, so a few small modifications were required. The props fit on his 3D printer bed along their long edge allowing for ease of slicing and removal of support material. For post-processing, [Anton] is using acetone vapor smoothing on his ABS printed design. They come out with a nice glossy sheen, and should be reasonably more aerodynamic than a prop with visible layer lines.
Although [Anton]’s prop is basically a replica of a normal, off-the-shelf quadcopter prop, 3D printing unique, custom props does open up a lot of room for innovation. The most efficient propeller you’ll ever find is actually a single-bladed propeller, and with a lot of experimentation, it’s possible anyone with a well-designed 3D printer could make turn out their own single-blade prop.

NBC News has reported the US Government may implement regulations in the coming days that would require anyone who buys an unmanned aircraft system to register that device with the US Department of Transportation.
The most simplistic interpretation of this news is that anyone with a DJI Phantom or a model aircraft made out of Dollar Tree foam board would be required to license their toys. This may not be the case; the FAA – an agency of the US DoT – differentiates between unmanned aircraft systems and model aircraft.
This will most likely be the key thing to watch out for in any coming regulation. The FAA defines model aircraft as, “an unmanned aircraft that is capable of sustained flight in the atmosphere; flown within visual line of sight of the person operating the aircraft; and flown for hobby or recreational purposes.” Additionally, the FAA may not make any regulations for model aircraft. While this means planes and quads flown without FPV equipment may be left out of this regulation, anything flown ‘through a camera’ would be subject to regulation.
[Joop Brokking] wanted to know where his quadcopter was and had been. He thought about Google Earth, but assumed it would be difficult to get the GPS data and integrate it with Google’s imagery. But he discovered it was easier than he thought. He wound up spending around $10, although if his ‘copter didn’t already have GPS, it would have been more.
Hardware-wise, [Joop] made a pretty straightforward data logger using a small Arduino (a Pro Mini) and an SD Card (along with an SD breakout board). With this setup, NMEA data from the GPS comes in the Arduino’s serial port and winds up on the SD Card.

Not many people would like a quadcopter with an HD camera hovering above their property, and until now there’s no technical resource to tell drone pilots to buzz off. That would require actually talking to a person. Horrors. Why be reasonable when you can use a Raspberry Pi to hijack a drone? It’s the only reasonable thing to do, really.
The folks at shellIntel have been messing around with quads for a while, and have recently stumbled upon a vulnerability in the Pixhawk flight controller and every other quadcopter that uses the MAVLink protocol. This includes the Parrot AR.drone, ArduPilot, PX4FMU, pxIMU, SmartAP, MatrixPilot, Armazila 10dM3UOP88, Hexo+, TauLabs and AutoQuad. Right now, the only requirement to make a drone fall out of the sky is a simple radio module and a computer. A Raspberry Pi was used in shellIntel’s demo.
The exploit is a consequence of the MAVLink sending the channel or NetID used to send commands from the transmitter to the quadcopter in each radio frame. This NetID number is used so multiple transmitters don’t interfere with each other; if two transmitters use the same NetID, there will be a conflict and two very confused pilots. Unfortunately, this also means anyone with a MAVLink radio using the same NetID can disarm a quadcopter remotely, and anyone with a MAVLink radio can tell a quad to turn off, or even emulate the DJI Phantom’s ‘Return to China’ function.
The only required hardware for this exploit is a $100 radio and three lines of code. It is certainly possible to build a Raspberry Pi-based box that would shut down any Pixhawk-equipped quadcopter within radio range, although the folks at shellIntel didn’t go that far just yet. Now it’s just a proof of concept to demonstrate that there’s always a technical solution to your privacy concerns. Video below.
