During internal testing last month, the Munich-based firm recorded its Apex Recordhunter drone hitting a top speed of 699 km/h (434 mph) in straight and level flight. That incredible result convincingly outpaces the current world record holder with a recorded top speed of 657.59 km/h (409 mph). However, a Guinness World Record entry is pending, with a formal attempt to crack that achievement expected to take place in the coming weeks, reports ComputerBase (machine translation).
