GoKawiilGeorgia Tech student's dorm-built jet drone unofficially tops 491 mph speed record
Aerospace engineering student Tomas Salvo built a jet-powered drone called Reaper in his Georgia Tech dorm room, which unofficially hit 491 mph, surpassing the previous 465 mph record for small jet-powered drones. The $13,000 aircraft uses a custom carbon fiber shell, laser-cut internal structure, and a 250N jet engine with a titanium 3D-printed nozzle, and Salvo says three such Reapers can sustain that speed for four minutes per tank.
