SUMMARY
The Pro Drone Hub has set an unofficial world record for the fastest drone, reaching 453mph (730 km/h) with their "Blackbird" drone, which features specialized saw-tooth carbon propellers. The record attempt was not without incident, as the drone was nearly lost around the 50th run. The team theorized Doppler shift might have affected radio signals, though other technical issues like battery or solder failure are considered more likely. The builders aim to reach the speed of sound (767mph), having previously achieved 388mph.
