A fully 3D-printed quadcopter has gained the title of the world’s fastest drone by reaching a top speed of 659 kilometers per hour (408 mph) with tailwind. Built and piloted by engineer and YouTuber Luke Maximo Bell along with his father, the Peregreen V4 officially recorded a two-run average of 657 kmph under Guinness verification. The drone additionally managed to reach an upwind speed of 599 kmph, which is said to be an improvement of 14 kmph over its predecessor.
With this achievement, the father-son duo once again claimed the speed title after their previous attempt was overtaken by Australian aerospace engineer Ben Biggs, who set a 626 kmph (389 mph) record with his Blackbird drone.
The project took over two years to engineer and involved computational fluid dynamics (CFD) modeling, rapid prototyping, and iterative flight testing to refine aerodynamics. The entire body of the Peregreen V4 was made using the Bambu Lab H2D 3D printer with multiple materials including PETG, PA6-CF, and TPU. “The new printer’s larger build volume and dual-nozzle system made it possible to print the body as one continuous piece. That gave us smoother aerodynamics and a much higher surface finish quality than before” said Luke in his YouTube video. The use of 3D printing also allowed the team to fine-tune mechanical flexibility, heat resistance, and aerodynamic integrity without relying on any external fabrication.
As for the motors, Luke went ahead with three options – the AOS Supernova, AMX 2826, and T-Motor 3120. These motors were first tested to gather live thrust readings using strain gauges along with an amplifier and Arduino board. After some rigorous flight testing, the team went with the T-Motor 3120 as it offered better reliability in terms of temperatures along with zero scrapping. The team also ended increasing the motor windings from 800 KV to 900 KV for higher RPM and a faster top speed.
To improve aerodynamics, the team ran extensive airflow simulations using the AirShaper platform which eventually helped in creating a larger but smoother outer shell to cut through air more easily and reduce drag. Finally, the drone body was sanded and polished for a cleaner finish, while the propellers were tested and shortened from 7×5 inches to about 6 inches to improve efficiency at high speeds.
Beyond the world record itself, the Peregreen V4 is a testament to how far the DIY community has come. What once required aerospace-grade equipment and facilities can now be achieved with just a desktop 3D printer, simulation software, endless testing, and lots of patience. More importantly, the record is not expected to stand for long as Luke is already looking toward other tinkerers to go beyond the existing speed record very soon.
