Max and David reunite for UAV News Talk episode 434, bringing listeners a wide-ranging discussion on the latest UAV, eVTOL, and rotorcraft developments.

FAA Advisory Circular on Powered-Lift

They start with the FAA’s release of AC 21-17-4, the long-awaited certification guidance for powered-lift aircraft. Max explains how this 64-page document emphasizes performance-based outcomes rather than prescriptive design rules. Much of the content resides in Appendix A, covering equipment from cockpit voice recorders to flight data recorders. The standout requirement: aircraft must withstand impacts from a four-pound bird—a test historically performed with frozen chickens fired from “chicken guns.” David points out that eVTOLs, operating at lower altitudes, will likely encounter more bird strikes than traditional aircraft, making the requirement especially relevant.

Joby Acquires Blade Passenger Business

The hosts then dive into Joby Aviation’s $125 million acquisition of Blade’s passenger business. Blade, known for helicopter and charter flights around Manhattan, gives Joby an existing customer base, operational infrastructure, and valuable experience. Max and David consider how quickly wealthy corporate travelers might switch from Sikorsky and Bell helicopters to Joby’s quieter eVTOLs. They expect a mixed fleet for years, with pricing likely used as an incentive to encourage adoption. The acquisition excludes Blade’s medical transport division but secures its premium commuter routes.

China’s Two-Ton eVTOL

China’s aviation industry stunned observers with the unveiling of a two-ton eVTOL. Although the aircraft carries 880 pounds of payload—comparable to a Robinson R44—Max notes the figure is underwhelming relative to the aircraft’s size. David highlights its 124 mph cruising speed and one-hour endurance, branding it part of China’s new “low-altitude economy.” Max contrasts U.S. and European reserve requirements for electric aircraft, noting that European operators can fly with only a 10-minute reserve, boosting usable endurance. They also reference the FAA’s MOSAIC rules, which propose pilot certificates requiring just 20 hours of training for simplified eVTOL controls—though both hosts believe real-world training times will be closer to 40 hours.

Ukraine’s Drone Bicycle Rescue

In a dramatic wartime innovation, Ukraine used drones to deliver electric bicycles to a soldier trapped behind enemy lines. After multiple attempts, including one foiled by a landmine, the soldier finally escaped thanks to the unusual delivery. Max appreciates this rare “good news” drone story, contrasting it with the common use of UAVs as weapons. David likens the aerial surveillance role to Vietnam-era A-1 Skyraiders providing overwatch during rescues.

Boeing Lawsuit and Startup Dispute

The discussion shifts to Boeing’s legal troubles with Zunum Aero, a Seattle-based hybrid-electric startup. After bankruptcy, Zunum sued Boeing for intellectual property theft. Though the case has bounced between rulings, the Ninth Circuit reinstated a $72 million verdict against Boeing, highlighting concerns about the aerospace giant’s corporate practices.

Waterfall Rescue with Drones and Helicopters

Finally, the hosts cover a California hiker who spent days trapped behind a waterfall in the Sequoia National Forest. Drones first located him before a sheriff’s helicopter hoisted him to safety. David jokes about future quadcopters equipped with hoists, while Max cautions hikers about the Seven Teacups Trail. The story reinforces the growing synergy between UAVs and helicopters in rescue operations.

NTSB News Talk 

BVLOS rules, school safety drones, NASA’s Mars helicopters, and Michigan’s 40-mile drone research skyway take center stage in UAV News Talk episode 433, hosted by Max Trescott and David Vanderhoof. The discussion begins with the newly introduced LIFT Act—short for Leading Innovation in Flight Technology Act—proposed by Representative Jen Kiggans of Virginia on July 24, 2025. The bill would compel the Department of Transportation to accelerate FAA rulemaking for Beyond Visual Line of Sight (BVLOS) drone operations. The hosts explore how AI could be used to speed approvals, contrasting deterministic AI rule-checking with generative AI’s potential for errors, and weighing how this fits—or clashes—with the FAA’s traditionally deliberate safety-first approach.

Next, the conversation shifts to Florida’s plan to trial armed drones for school security. Developed by Campus Guardian Angel, these drones would be stored on-site in protective boxes and launched within seconds to engage an active shooter—potentially firing powder pellets to incapacitate the suspect. Max and David raise practical questions about launch authority, piloting, targeting in chaotic conditions, and operational control from a central dispatch center. They note the program’s $1,000-per-month cost and early deployments in four Florida school districts and one Texas university.

Video of the Week: A vivid example of drones aiding law enforcement—a Scottsboro, Alabama thermal video showing the nighttime capture of an attempted murder suspect hiding beside railroad tracks. The video’s bright, detailed imagery stands out from typical black-and-white thermal feeds, illustrating drones’ growing value in search and apprehension.

From terrestrial policing to interplanetary exploration, the episode dives into NASA’s ambitious proposal to send six helicopters to Mars. Building on the Ingenuity mission’s unexpected 72-flight success, the new fleet could haul 11 pounds each, operate autonomously, and even act as communication relays to extend range. The hosts discuss rotor speed adjustments for Mars’ thin atmosphere, coaxial rotor benefits, and lessons from Ingenuity’s final hard landing caused by a rotor strike.

Back on Earth, Michigan unveils its M Air Research Skyway—a 40-mile-long drone corridor enabling BVLOS operations, swarm testing, and drone traffic management (UTM) development. The University of Michigan’s engineering programs, private partners, and state agencies will collaborate to test delivery drones, advanced operations, and multi-drone coordination in a controlled yet realistic environment. Max notes the unique scale compared to most U.S. university programs, and David speculates on potential eVTOL or medical delivery applications.

The episode wraps with a look at China’s booming “low-altitude economy” and its newly recognized profession: drone flight planner. With over 247,000 licensed drone operators and 2.17 million drones registered, China sees structured planning roles as key to safety and efficiency. Max compares these figures with the United States’ 460,000 Part 107 pilots and 822,000 registered drones, and the hosts discuss differences in regulatory pace and industry growth.

Packed with policy developments, technology advances, and global industry insights, UAV News Talk 433 delivers essential updates for drone pilots, UAS professionals, and anyone tracking the future of unmanned aviation.

In Episode 432 of UAV News Talk, Max Trescott and David Vanderhoof explore the evolving role of drones in public events, law enforcement, and emergency response—highlighting both their growing utility and the risks of poor coordination. Titled "Drone Fireworks, Police UAVs, and a Black Hawk Crash in Texas," this episode covers breaking drone news from California and Texas, trends in UAV policing, and innovations in helicopter autonomy from Sikorsky and Skyryse.

The episode opens with Max sharing a personal story about diving back into ham radio and noting the crossover with FPV drone pilots who use amateur radio frequencies for extended range. It’s a humorous but insightful segue into the broader theme: drones are becoming essential tools in unexpected places, from backyard hobbies to high-stakes public safety operations.

Max Trescott and David Vanderhoof dive into the future of drone delivery in Episode 431 of UAV News Talk. Max shares his firsthand experience receiving multiple packages via drone as part of a pilot program from Matternet, a Mountain View, California-based drone logistics company. After visiting Matternet’s headquarters and observing the behind-the-scenes operations, Max witnessed the packaging, pre-flight procedures, and live flight operations, including the dispatch and precise delivery of chocolate bars and snacks.

Matternet’s program currently serves residents in Mountain View and Sunnyvale, delivering small items such as chocolates and drinks for free as part of a test initiative to gather feedback and flight data. Max details how customers apply to join the program, undergo a home site survey, and then place orders via a website. Deliveries are tracked in real time, and drones use tethers to gently lower packages into designated clear areas, where they automatically release the payload and return to base.

Listeners hear live audio from Matternet staff explaining how deliveries are prepared, packaged, and executed under the watchful eye of a remote pilot monitoring telemetry and airspace conditions. Max describes the system’s precision and automation—including launchpads, a “mushroom-shaped” autonomous docking hub for future point-to-point missions, and how flight plans are uploaded for mostly autonomous execution.

The drones, significantly larger than consumer quadcopters, are equipped with carbon fiber propellers and make a lower-pitched, deeper noise due to their larger rotors spinning at lower RPMs. The box itself, constructed of cardboard with padded interiors, is pristine upon arrival, having avoided the rough handling common in traditional delivery systems.

David questions the economics of drone delivery, especially for low-cost items like chocolate, and Max suggests the long-term potential lies in delivering high-value or time-sensitive items, such as medical samples. They discuss how drone delivery is expanding, with Amazon, DoorDash, and companies like Flytrex, Zipline, and Alphabet’s Wing offering services in cities like Phoenix, College Station, and Dallas-Fort Worth.

While drone delivery is advancing, both hosts acknowledge challenges remain—including weather, regulatory hurdles, noise concerns, and public perception. Max’s takeaway: while drone delivery isn’t yet widespread, real-world operations like Matternet’s signal that UAV logistics are finally reaching the cusp of mainstream adoption.

In episode 430 of UAV News Talk, Max Trescott and David Vanderhoof return from vacation with urgent news and safety concerns in the drone industry. The episode opens with a major headline: the DJI Mavic 4 Pro is not available in the United States. Although the drone boasts high-end specs—including a 6K camera and improved flight performance—it’s currently unavailable in the U.S. due to concerns about data security and alleged ties between DJI and the Chinese government.

The ban stems from a long-standing effort by U.S. government agencies to restrict the use of DJI drones, especially after reports emerged that some DJI models were transmitting sensitive data back to China. The Pentagon, in particular, flagged DJI as a national security risk. In light of this, many online resellers and websites claiming to sell the Mavic 4 Pro may be scams. Max warns of fake DJI websites offering steep discounts, unauthorized sellers providing units without warranty coverage, and used drones that are “bricked” due to being locked to previous owners' DJI accounts. Buyers are urged to verify the source before purchasing any DJI drone—especially when new models are not officially available.

Next, the discussion shifts to drone battery fires, a serious issue affecting both hobbyist and commercial UAV operators. Max highlights a recent vehicle fire in Mountain View, California, caused by a drone battery left charging on the passenger seat of a truck. Though the fire was extinguished quickly and injuries were minor, it serves as a critical reminder of the dangers associated with charging LiPo (lithium polymer) batteries in enclosed or flammable environments.

In a separate and more devastating incident, a house in Kenosha County, Wisconsin was completely destroyed by a fire linked to drone batteries charging unattended. Tragically, several pets were lost in the blaze. According to reports, the batteries were connected to a newly purchased six-foot drone, and the homeowner had left them charging for hours while away from home. The episode underscores the importance of charging drone batteries only in safe, monitored locations—preferably on a non-flammable surface such as concrete and never inside unattended vehicles or homes.

From fire hazards to electric flight innovation, Max and David then explore the historic cross-Atlantic flight of Beta Technologies’ Alia electric aircraft. The Beta Alia CX300, a fixed-wing eVTOL aircraft, is currently touring Europe and made headlines for flying across the Irish Sea under VFR rules. Its final destination is Bristow Helicopters in Norway, a company known for operating offshore flights to oil platforms.

The Alia’s 250-nautical-mile range—significantly farther than most other electric VTOL aircraft—positions it as a promising alternative to traditional helicopters. Max notes that replacing helicopters for short regional missions is one of the most realistic and cost-effective early use cases for electric vertical takeoff and landing (eVTOL) aircraft. The Beta Alia also features fixed wings to improve lift and efficiency during cruise, giving it a hybrid profile that blends characteristics of both airplanes and helicopters.

In defense-related drone news, the episode also covers the U.S. Department of Defense’s recent unveiling of two “loyal wingman” drone programs—the QF-42 and QF-44. These autonomous fighter drones are designed to fly alongside manned aircraft like the upcoming F-47 Next Generation Air Dominance fighter, providing added firepower, surveillance capability, and operational safety. David notes that these aircraft are in the pre-production phase and may be deployed in the coming years as force multipliers in high-risk combat zones.

The rise of autonomous military drones is reshaping battlefield tactics, and even U.S. ground troops are training to evade detection from enemy drones. A recent report reveals that the U.S. Army is now showing new recruits how they appear to enemy UAVs during surveillance missions, emphasizing the importance of movement discipline and cover when drones are overhead.

On the civilian side, Max discusses a new product from uAvionix called SkyAlert—a wearable aircraft detection system designed for drone pilots and visual observers. The compact device receives dual-band ADS-B signals and gives real-time audio and visual alerts when manned aircraft are nearby. This enhances safety during drone operations, especially in mixed-use airspace near airports or urban areas. SkyAlert integrates with several popular electronic flight bag (EFB) apps like ForeFlight, SkyDemon, and OzRunways. Although still on pre-order, its $499 price point may appeal to commercial operators and professional drone pilots seeking an added layer of situational awareness.

While wearable drone safety tech shows promise, Max and David debate whether alarm fatigue or sensory overload could diminish its effectiveness. Drawing parallels to over-complicated aircraft cockpits, they emphasize the need for smart filtering and possibly automated drone responses, such as auto-landing when a threat is detected.

The episode closes with a tease for next week: Max received two drone deliveries to his front lawn—not deliveries of drones he purchased, but actual drones lowering deliveries into place and flying off. This real-world experience with drone delivery services will be the focus of the next episode.

From DJI drone bans and battery fire safety tips to electric aircraft innovation and military UAV trends, episode 430 offers a comprehensive look at the evolving landscape of drone technology.

Drone Safety Day is April 29, a drone that changes shape, jump-starting your car with a drone, Florida bans DJI from government agencies, decision-making for small UAVs, drones that work together without colliding, adding VTOL to a fixed-wing drone, agave farmers saving water, land a drone in Red Square.

Drone Safety Day is Saturday, April 29, 2023. The annual campaign is dedicated to educating the drone community on the importance of flying safely. You can download the 2023 Drone Safety Day Playbook  and 2023 Drone Safety Day Flyer. You can also visit the Drone@Home page to find ideas to participate at home. Register your event. 

University of Tokyo graduate students created drone prototypes that can rearrange into different structural shapes midair. The drones have individual segments with multi-axis gimbal systems. Each segment has its own propulsion unit, that can thrust in any direction. The drones can change their configuration to hold or move objects. They’ve also developed the SPIDAR quadruped robot that has joints in each leg and can fly.

This patent contemplates drones that assist motorists stranded with a dead battery. The Ford vehicle would transmit a “dead battery” signal and its location then a drone would fly to the vehicle, open the hood, connect to the battery, and jump-start the vehicle.

Florida Governor Ron DeSantis is forbidding government agencies from using drones manufactured by DJI. Only drones made by a small number of “approved manufacturers” can be purchased. Agencies have until January 1, 2023, to stop using drones not on the list. Many departments have already grounded their fleets. They told lawmakers that the Florida-approved drones are far more expensive and much less capable.

Sen. Tom Wright, R-New Smyrna Beach said, I’m not going to let one officer risk his life or her life because somebody thinks that these things talk to China. I cannot imagine what China would really want to see when we pull over a DUI, when we stop a speeding car, when we arrest somebody for an outstanding warrant.”

University of Notre Dame computer scientists and engineers are developing an automated decision-making system for small drones under a $5.3 million 3-year NASA grant. Notre Dame will enhance NASA’s current drone traffic management system and develop decision-making software that permits or denies flight requests by evaluating a drone’s safety track record, equipment readiness, operator preparedness, and maintenance procedures.

The Robust MADER system lets drones work together without collisions. Each drone calculates its own trajectory and checks with nearby drones to be sure it won’t collide with any of them. The system is an asynchronous, decentralized, multiagent trajectory planner. By broadcasting both the newly optimized trajectory and the committed trajectory, and by performing a delay check step, RMADER is able to guarantee safety even with communication delays. The new system has been validated through simulation and hardware flight experiments. A 100% success rate of collision-free trajectory generation was achieved.

The Flying Launch and Recovery System (or FLARES) turns a fixed-wing drone into a VTOL. The FLARES aircraft is a multicopter drone with four propeller arms. A mechanism on the underside clasps onto the body of a fixed-wing drone. The pair then rise vertically. At altitude, FLARES releases the fixed-wing drone. FLARES is manufactured by Hood Tech and was primarily designed for use on ship decks.

Boeing’s Insitu subsidiary offers a package that includes its Integrator fixed-wing drone and Hood’s FLARES system. Integrator flight time is reportedly up to 16 hours with a maximum payload of 40 lb (18 kg). Insitu says that payload capacity would be lower if Integrator had its own integrated VTOL system.
