South Africa Reclaims the World’s Fastest Drone Crown

For a brief moment, the world’s fastest drone passport wasn’t green. That problem has now been corrected. Father-and-son duo Mike and Luke Bell are back on top with the Peregreen V4, a flying missile that clocks 657 km/h on average and treats the laws of aerodynamics like optional guidelines.

South Africa has reclaimed its seat at the pointy end of the speed table, and once again it involves a father, a son, and a flying object that treats physics as a polite suggestion.

After briefly losing the crown in December 2025, Mike Bell and his son Luke Bell are back on top with the Peregreen V4, now officially the fastest drone on Earth. Again.

Faster than common sense

Across four officially logged speed runs, the Peregreen V4 recorded an average speed of 657 km/h, with a peak of 659 km/h. To put that in everyday terms: that is faster than all supercars including the crazy BYD, race bikes, and a few aircraft you would rather not mention at a dinner party.

This reclaiming of the title was personal. In October 2025, the Bells’ Peregreen V3 had already made history at 585 km/h. Then along came Australian aerospace engineer Ben Biggs, whose Black Bird drone raised the bar to 626 km/h. Cue South African silence, furious tinkering, and the sound of CAD software being abused late into the night.

Five months of obsession

Luke explained that the V4 was not a quick upgrade. For five months, nearly every component was questioned, tested, rejected, tested again, and occasionally sworn at.

Motors were the first battleground. AOS, AMAX, and T-Motor units were tested on benches and in real flight conditions. The winner was not the most aggressive option, but the most dependable one: four T-Motor 3120 units.

They did not produce the highest raw thrust, but they ran cooler, behaved predictably, and most importantly did not chew themselves to pieces. Previous record attempts had shown scraping on stators. At nearly 660 km/h, that is the mechanical equivalent of a ticking bomb.

The secret sauce

The real magic, according to Mike, came from aerodynamics. Specifically, 3D-printed streamliners fitted over the base of each propeller. These smooth out airflow and slash drag, which matters enormously when you are trying to punch a hole through the air at speeds usually reserved for jet intakes.

Earlier versions had avoided these parts because crashes were common and extra stress was unwelcome. This time, confidence was higher. CFD simulations using AirShaper confirmed what instinct suggested: blunt motor ends create ugly pressure pockets, while streamliners clean the airflow and return lost thrust.

In short, less turbulence, more speed, fewer mechanical tantrums.

Stress testing at lunatic speeds

Before flight, the propeller assemblies were tortured on a test bench. The spinners were spun past 70,000 rpm to check for structural weakness.

They survived without complaint.

For context, the drone never exceeds around 40,000 rpm in actual flight. This test was less “reasonable precaution” and more “let’s see what happens if we really annoy it”.

Filming the unfilmable

Then came a very modern problem: how do you film something that crosses the sky faster than your eyes can politely track?

The solution was brilliant and slightly cheeky. They used the world’s second-fastest drone as the camera platform.

A custom 3D-printed tail mount was created to house an Insta360 X5 camera. This allowed the filming drone to record everything in 360 degrees, with reframing done afterwards. No missed passes. No “blink and it’s gone” moments.

Despite the extra weight hanging off its tail, the camera drone flew cleanly. The footage, according to Luke, is “epic”, which feels like an understatement given the speeds involved.

The record runs

Guinness rules require runs in opposite directions to cancel out wind advantage. Early testing showed why. One run hit 649 km/h downwind, while the return struggled at 585 km/h. Average speed matters. Excuses do not.

On record day, four runs were completed. Two northwest, two southeast.

The fastest northwest pass clocked 656 km/h. The fastest return hit 659 km/h. That delivered an official average of 657 km/h.

The old record was beaten by 31 km/h. Not nudged. Not edged. Properly dismantled.

Back where it belongs

So yes, the title is back in South Africa. Again. Built in a workshop, refined with software, tested with stubborn patience, and flown with nerves of steel.

The Peregreen V4 is not just the fastest drone in the world. It is proof that when curiosity, engineering, and family obsession collide, even the sky struggles to keep up.
