Garage-built drone hits 730 km/h unofficially — faster than most fighter jets cruise
A hand-built drone called Blackbird reached 730 km/h (453 mph) during a test run in Australia in May 2026, making it the fastest DIY drone ever recorded. The official Guinness record sits at 657.59 km/h, set by the Peregreen V4 in December 2025. Blackbird's run isn't certified yet — but the numbers are hard to ignore.
The build
Blackbird is the work of Australian hobbyist Benjamin Biggs, who runs the Drone Pro Hub channel, and is locked in an ongoing speed rivalry with South African father-and-son team Luke and Mike Bell, who currently hold the official Guinness title. The two camps have swapped records back and forth since November 2025, driving each other to increasingly extreme engineering.
The key upgrade for this run was a set of custom carbon-fiber propellers with a sawtooth leading edge. At extreme speeds, standard props generate turbulent vortices that kill efficiency. The sawtooth geometry disrupts those vortices, keeping airflow attached longer. The tradeoff: the drone drew 400 amps for roughly ten seconds, pushing battery temperatures to 80°C — hot enough to melt heat-shrink tubing on the wiring, per Tom's Hardware.
The record math
The 730 km/h peak was a downwind pass with a 55 km/h tailwind assist. Guinness rules require two runs in opposite directions to cancel out wind effects. Blackbird managed 640 km/h on the return headwind pass, giving a two-direction average of 685 km/h — still well above the official 657.59 km/h record, reports DroneXL.
The problem: no certified Guinness witnesses were present, and the timing zone wasn't officially set up. That means the run counts as unofficial. Biggs hasn't confirmed when a fully accredited attempt is planned, but the 685 km/h average suggests an official record is within reach.
Why it matters beyond YouTube
Blackbird weighs around 2 kg and fits in a backpack. The fact that a hobbyist can build something approaching commercial aviation speeds — a Boeing 737 cruises at around 885 km/h — using off-the-shelf electronics and custom-printed carbon fiber parts signals a genuine shift in what maker-level engineering can achieve. Consumer drones like the DJI FPV top out near 140 km/h. The gap between hobbyist records and commercial hardware has never been wider.
The engineering lessons here — propeller aerodynamics, thermal management at extreme power draws, airframe rigidity at transonic-adjacent speeds — are the kind of data that feeds back into professional racing drone design and, eventually, commercial development.
