Overview
- Guinness World Records certified a two-run average of 657.59 km/h (408.60 mph) for the battery-powered RC quadcopter.
- The record was set in Cape Town on December 11, 2025, using opposing-direction passes to offset wind effects.
- Peregrine V4 reached a reported 659 km/h with tailwind and 599 km/h upwind during the verified attempt.
- A largely single-piece body printed on a Bambu Lab H2D improved surface finish and aerodynamics over prior versions.
- Four T-Motor 3120 brushless units at 900 kV, AirShaper-driven CFD refinements, and shortened propellers delivered the gains as the Bells reclaimed the title from Ben Biggs’ 626 km/h Blackbird.
