Key Developments & Data
A team of University of Bath graduates, known as The Mach Initiative, has constructed a 20-pound 3D-printed RC aircraft designed to hit Mach 0.8 (614 mph) and break the 9-year-old Guinness World Record for the fastest model aircraft.
The "Kingchaser" aircraft is built primarily using standard PETG plastic, utilizing PPS-CF reinforced with carbon fiber, aluminum, and steel for the engine housing to prevent warping.
To shield the 3D-printed body from the intense heat of the jet turbine, the team incorporated titanium exhaust sheets and aluminum tape, replacing an earlier aluminum skeleton with carbon fiber rods to save weight.
The team previously achieved a top speed of 205 mph (330 km/h) with their smaller "Kingfisher" prototype using a Jetcat P60 engine, which produced 63 Nm of thrust.
The final Kingchaser model is equipped with a fully instrumented avionics telemetry system, an FPV camera setup, and 70 kg-cm high-torque servos to control the elevon flaps at extreme speeds.
