Drone fliers in the USA must soon display their registration markings on the exterior of their craft, rather than as was previously acceptable, in accessible interior compartments. This important but relatively minor regulation change has been announced by the FAA in response to concerns that malicious operators could booby-trap a craft to catch investigators as they opened it in search of a registration. The new ruling is effective from February 25th, though they are inviting public comment on it.
As airspace regulators and fliers across the world traverse the tricky process of establishing a safe and effective framework for multirotors and similar craft we’ve seen a variety of approaches to their regulation, and while sometimes they haven’t made complete sense and have even been struck down in the courts, the FAA’s reaction has been more carefully considered than that in some other jurisdictions. Rule changes such as this one will always have their detractors, but as an extension of a pre-existing set of regulations it is not an unreasonable one.
It seems inevitable that regulation of multirotor flight will be a continuing process, but solace can be taken at the lower end of the range. A common theme across the world seems to be a weight limit of 250 g for otherwise unrestricted and unregistered craft, and the prospects for development in this weight category in response to regulation are exciting. If a smaller craft can do everything our 2 kg machines used to do but without the burden of regulation, we’ll take that.
First Person View (or First Person Video) in RC refers to piloting a remote-controlled vehicle or aircraft via a video link, and while serious racers will mount the camera in whatever way offers the best advantage, it’s always fun to mount the camera where a miniature pilot’s head would be, and therefore obtain a more immersive view of the action. [SupermotoXL] is clearly a fan of this approach, and shared downloadable designs for 3D printed cockpit kits for a few models of RC cars, including a more generic assembly for use with other vehicles. The models provide a dash, steering wheel, and even allow for using a small servo to make the steering wheel’s motions match the actual control signals sent. The whole effect is improved further by adding another servo to allow the viewer to pan the camera around.
Check out the video embedded below to see it in action. There are more videos on the project’s page, and check out the project’s photo gallery for more detailed images of the builds.

If your favorite movie is Ratatouille, now would be a good time to read a different article. Rats on the Galápagos Islands are an invasive species and eradication is underway. This is not a first for the islands, and they are fiercely protected since they are the exclusive home to some species including the distinctive tortoise from which the island derives its name and of course finches. Charles Darwin studied the finches while writing On the Origin of Species. So yeah, we want to keep this island from becoming unbalanced and not disturb the native wildlife while doing it. How do we check all these boxes? Technology! Specifically, hexacopters carrying rat poison.
The plan is simple, drive a truck to a central location, release the
hounds drones and fifteen minutes later they come back after flying high above the indigenous wildlife and dropping pest control pellets. The drones save time and labor, making them a workhorse rather than a novelty. This work experience on their resume (CV) could open the door to more dirty work or more wholesome activities. Who is to say that the same drones, the exact same ones, couldn’t deliver plant seeds, or nourishing food to the dwindling species harmed by the rat population explosion.
What would you deliver with drones? How about providing parcels or just learning a better way to navigate?

There’s something thrilling about decoding an unknown communications protocol. You start with a few clues, poke at the problem with some simple tools, and eventually work your way up to that first breakthrough that lets you crack the code. It can be frustrating, but when you eventually win, it can be very rewarding.
It seems that [Jason] learned this while decoding the wireless conversation between his mass-market quad and its controller. The quad in question, a Yuneec Q500, is one of those mid-range, ready-to-fly drones that’s targeted at those looking to get in the air easily and take some cool pictures. Unsure how the drone and controller were talking, [Jason] popped the covers and found a Zigbee chipset within. With the help of a $14 Zigbee USB dongle and some packet sniffing software from TI, [Jason] was able to see packets flowing, but decoding them was laborious. Luckily, the sniffer app can be set up to stream packets to another device, so [Jason] wrote a program to receive and display packets. He used that to completely characterize each controller input and the data coming back from the drone. It’s a long and strange toolchain, but the upshot is that he’s now able to create KML in real time and track the drone on Google Earth as it flies. The video below shows the build and a few backyard test flights.
Congratulations to [Jason] for breaking the protocol and opening up drones like this for other hackers. If you’re interested in learning more about Zigbee sniffing, you can actually hack a few smarthome gadgets into useful sniffers.

Regular readers will have followed our series of posts looking at the issues surrounding reports of drones in proximity to aircraft, and will have noted that we recently asked our community how they would approach the detection and handling of marauding drones in controlled airspace. We are mere amateurs though by comparison to a team with its roots in Delft University of Technology’s Micro Air Vehicle Laboratory, because they have approached the problem through DroneClash, a spectacle best described as akin to a Robot Wars competition for drones. Their website states that “Anything goes, with one exception: no jamming“, and teams will do battle before an audience for a share in a considerable prize fund.
The fun is not however limited to team members. People in the audience will also be able to participate, by being invited to try their luck at bringing down a TinyWhoop that will periodically fly into the arena for a chance at their own prize. The ubiquitous cheap toy drone will be accessible through software, and would-be attackers are invited to register in advance to take a pop at it.
It looks as if DroneClash will be an unmissable event for anyone able to make it to the Netherlands on March 16th. We’ve mentioned it in past years, and we look forward to seeing what comes out of it this year too.

Decades ago, [wilmracer]’s grandfather was piloting a B-17 over the Rhine, and as it goes, aviation runs in families. Now, more than 70 years later [wilmracer] is deep, deep into remote controlled aircraft, and he’s building an exacting scale model of the B-17G his grandfather flew on his last bombing mission over Europe.
This is a scratch build, with the design taken directly from the plans and schematics of a B-17. [wilmracer] has already paid the money to go up in the preserved B-17 Aluminum Overcast to get a better idea of the layout, and now he’s deep into cutting foam and bending balsa sheets. The first part of the build was arguably the hardest, and the main landing gear was expertly constructed out of aluminum tube and linear servos. The horizontal stab follows traditional building techniques of foam and carefully sanded balsa sheets. The fuselage is impressive, with the formers built out of foam, and eventually covered in 1/16″ balsa and wrapped in fiberglass.
If you’re going to do a large-scale model airplane, that also means you’ve got to do detailing. That means steam gauges rendered in 3D printed parts. [wilmracer] is modeling the cockpit and the machine guns in 1:9 scale. This is going to be an awesome build, and yes, there will eventually be plans.
Of course, this isn’t the biggest small B-17 ever built. That record goes to the 1:3 scale Bally Bomber, a real, not remote controlled plane built over the course of two decades by [ Jack Bally]. This is a real plane with a 34 foot wingspan that weighs 1800 pounds. Yes, it flies, and it went to Oshkosh last summer. Remote control really is the way to go with something like this, though: you can appease the rivet counters, put more power on the props, and you don’t need to worry too much about pesky things like regulations and laws. We’re looking forward to see where this project goes, and to the sound of a great PLA overcast thundering over the treetops.
The wheels of government move slowly, far slower than the pace at which modern technology is evolving. So it’s not uncommon for laws and regulations to significantly lag behind the technology they’re aimed at reigning in. This can lead to something of a “Wild West” situation, which could either be seen as a good or bad thing depending on what side of the fence you’re on.
In the United States, it’s fair to say that we’ve officially moved past the “Wild West” stage when it comes to drone regulations. Which is not to say that remotely controlled (RC) aircraft were unregulated previously, but that the rules which governed them simply couldn’t keep up with the rapid evolution of the technology we’ve seen over the last few years. The previous FAA regulations for remotely operated aircraft were written in an era where RC flights were lower and slower, and long before remote video technology moved the operator out of the line of sight of their craft.
To address the spike in not only the capability of RC aircraft but their popularity, the Federal Aviation Administration was finally given the authority to oversee what are officially known as Unmanned Aerial Systems (UAS) with the repeal of Section 336 in the FAA Reauthorization Act of 2018. Section 336, known as the “Special Rule for Model Aircraft” was previously put in place to ensure the FAA’s authority was limited to “real” aircraft, and that small hobby RC aircraft would not be subject to the same scrutiny as their full-size counterparts. With Section 336 gone, one could interpret the new FAA directives as holding manned and unmanned aircraft and their operators to the same standards; an unreasonable position that many in the hobby strongly rejected.
At the time, the FAA argued that the repealing Section 336 would allow them to create new UAS regulations from a position of strength. In other words, start with harsh limits and regulations, and begin to whittle them down until a balance is found that everyone is happy with. U.S. Secretary of Transportation Elaine L. Chao has revealed the first of these refined rules are being worked on, and while they aren’t yet official, it seems like the FAA is keeping to their word of trying to find a reasonable middle ground for hobby fliers.
