The Kingchaser, a remote‑controlled aircraft built mainly from PETG, PPS‑CF, carbon‑fiber rods and aluminum, uses a Jetcat P60 miniature jet turbine engine delivering 63 N·m of thrust and weighs about 20 lb (9 kg).
Its target speed of Mach 0.8 is intended to break the current Guinness World Record held by German pilot Neils Herbrich, while the earlier Kingfisher model, measuring just under a meter, reached a top speed of 205 mph (330 km/h) with the same engine.
