My college dorm project just broke the world speed record.
Reaper hit 790 km/h (491 mph) carrying a 1.2 kg (2.6 lb) payload.
These 3 Reapers are now the world’s fastest small jet-powered drones.
Each of them can hold that speed for 4 minutes on a full tank.
Reaper can be rail- or truck-launched, climb to 2,000 m (6,600 ft) in under 20 seconds, then fly for 50 km (31 mi) at full speed.
This is now a reliable and repeatable system. Future testing and small optimizations should push the top speed past 800 km/h (500 mph).
