He aerospace engineer of Australian origin Ben Biggs and his partner Aidan, responsible for the YouTube channel Drone Pro Hub, They made a model of drone capable of traveling at a pace never before recorded.
The design was made to surpass the record held by another aircraft company, and now seeks to enter the Guinness statistics.
For the device to reach such speed, the creators provided it with some special propellers.
The impressive flights of the «Blackbird» and the reasons for its creation
Ben Biggs and Aidan, from the popular channel Drone Pro Hubunveiled their latest version of the drone called «Blackbird«.
To do so, they uploaded a video in which they can be seen maneuvering the device, which traveled at a speed unprecedented for a drone.
In the test in which the wind moved in favor, it reached the 730 kilometers per hourwhile, when it moved in the opposite direction, it reached 640 km/h, so the average of the two flights was 685 km/h.
Both the maximum and average marks convert the Blackbird in the fastest drone ever built to date, since both figures exceed the previous record of 659 km/h registered by the Bell company with the “Peregreen V4”.
Although its record has not yet been officially approved by Guinness World Records, the invention arouses enormous expectations within the aeronautical engineering community and FPV fans (First Person View, the technology that allows you to pilot the drone in first person using real-time video).
The current Blackbird project was born after Drone Pro Hub lost its previous record.
At the end of December 2025, with a previous model of this drone, it had achieved a speed close to 626 km/h, but shortly after the Bell team managed to surpass it. Biggs and Aidan’s response was immediate: completely redesign the propulsion system of the Blackbirdespecially the propellers.
Tilted and serrated propellers: the key to the Blackbird’s speed
The technical secret of the new Blackbird record lies in the propellers hand-made carbon fiber. At first glance they may seem similar to those of any high-performance drone, but they incorporate two fundamental differences.
The first is an extremely steep angle of attack with respect to the direction of flight. The creators did not reveal the exact degree of inclination of the propellers, although they did confirm that it is an unusual configuration even within the world of speed drones.
The second, probably the most striking, are the serrated leading edges of blades. Instead of a completely smooth profile, the propellers feature small «»sawtoothThis geometry generates microvortices (small eddies of air) at the point where the air first impacts the blade.
As the developers explain, these microvortices allow the air flow to remain attached to the surface of the propeller even under very aggressive angles of attack.
Without them, the flow would separate prematurely, drastically reducing aerodynamic efficiency. In technical terms, the design stabilizes the boundary layer and prevents losses of lift and thrust at extreme speeds.
