The Drone Pro Hub team recorded their drone reaching a top speed of 605 km/h. The feat was the outcome of an 18-month effort headed by FPV specialist Benjamin Biggs. The quad-rotor drone, mounted on a base for take-off, featured onboard GPS telemetry that allowed speed monitoring.
While not recognized as an official record, they tested the right way and calculated the average speed of the drone to be 585.5 km/h. For context, to keep speed record measurements accurate, Guinness World Records requires drones to be flown in both directions: upwind and downwind. This is to cancel out the effect of the wind to a reasonable degree. In total, Drone Pro Hub did four runs: two with the wind and two against it. They picked the top speed from each direction and averaged them to calculate the speed.
The drone was built for one purpose, and that is extreme velocity. It featured high-performance ESCs and a custom aerodynamic frame to keep drag to a minimum. This is not the end of the road, as Drone Pro Hub plans to go beyond this speed, while documenting the build process as well as the testing on their YouTube channel.
