The world’s fastest drone title has changed hands once more. YouTuber and engineer Luke Maximobell, together with his father, has reclaimed the Guinness World Record with their latest creation, Peregreen V4, a fully 3D printed quadcopter that reached a top speed of 657.59 kilometers per hour with tailwind.

The official two-run average—performed under Guinness verification—was 657 kilometers per hour (408 miles per hour), surpassing the previous record of 626 kilometers per hour (389 miles per hour) set just a month earlier by Australian aerospace engineer Ben Biggs with his Blackbird drone. More importantly, Peregreen V4 achieved an upwind speed of 599 kilometers per hour, a 14-kilometer-per-hour improvement over its predecessor’s 585-kilometer-per-hour result, marking genuine aerodynamic and propulsion progress.

3D printing flies with rapid iteration

The Peregreen V4 represents the culmination of more than two years of iterative engineering between Luke and his father, combining CFD modeling, real-world testing, and rapid prototyping enabled by 3D printing. The entire drone body was produced using Bambu Lab’s H2D dual-extruder printer, which allowed the combination of two materials—among PETG, PA6-CF, and even TPU for the camera mount and landing system—within a single print.

This approach enabled the team to fine-tune mechanical flexibility, heat resistance, and aerodynamic integrity without external fabrication. The ability to use two materials was essential for important parts like the drone’s tail and camera mount, where hard and flexible plastics were combined to handle impacts while staying strong.

“The new printer’s larger build volume and dual-nozzle system made it possible to print the body as one continuous piece,” Luke said in the video. “That gave us smoother aerodynamics and a much higher surface finish quality than before.”

Narrowing the gap to supersonic speeds

Beyond materials, the Peregreen V4 incorporates several hardware and design upgrades. The team selected T-Motor 3120 brushless motors for their balance of thrust and reliability after testing multiple candidates, including the AOS Supernova and AMX 2826. The motors were paired with 900 KV windings—up from 800 KV in the previous version—to increase top-end rotational speed.

To improve aerodynamics, the drone’s outer shell underwent extensive CFD optimization through the AirShaper platform, resulting in a larger, smoother body contour that reduced drag. Additional refinements included sanding and polishing the carbon-fiber composite surface and trimming propeller blades from 7×5 inches to approximately 6 inches to optimize efficiency at high RPM.

Flight testing followed the industry-standard two-run average method—flying in both directions to offset wind effects—and was witnessed independently. During trials, Peregreen V4 recorded 657.59 kilometers per hour with a tailwind and a consistent 657-kilometer-per-hour mean speed, officially reclaiming the Guinness title for the world’s fastest drone.

While still well below the speed of sound (1,235 kilometers per hour at sea level), the latest result narrows the gap faster than many in the drone community anticipated. The idea that a drone entirely 3D printed on a desktop machine could go supersonic may have seemed preposterous just a couple of years ago. But it now becoming a real possibility.
