A team of University of Bath graduates has flown a 3D-printed remote-controlled aircraft equipped with a jet turbine, targeting a speed of Mach 0.8 to challenge the current Guinness World Record for the fastest model aircraft. The aircraft, named Kingchaser, was constructed from PETG, PPS-CF, carbon-fiber rods, and aluminum. Its creators say the project seeks to surpass the nine-year-old record held by German pilot Neils Herbrich. The maiden flight was documented in a YouTube video posted by the team. The achievement represents a convergence of additive manufacturing and high-speed model aviation, though verification of the record attempt will require formal testing under controlled conditions.
