Close to half the sound barrier, not exactly a speed demon.

And what is the "range" of flight?

Nice.

I too wonder how long it will stay aloft.

It would be interesting to know what percentage of max takeoff weight is the battery pack.

It seems like at least part of the real objective is for VTOL systems:
https://www.futureflight.aero/news-arti ... ion-flight
According to Rolls-Royce, the data harvested from the flight test program, which got underway in September, will be fed into plans to develop electric propulsion for new eVTOL and hybrid-electric regional fixed-wing aircraft. The company is a key supplier to the UK’s Vertical Aerospace for its four-passenger VA-X4 eVTOL design and is also working with Italy’s Tecnam to develop a nine-passenger commuter aircraft called the P-Volt.
That article also says:
According to Electroflight, the aircraft’s battery pack is the most power-dense ever assembled with a rating of 72 kW/hr
I assume that is supposed to be 72 kWh, which would make the battery around the same capacity as a Tesla I think.

IEEE Spectrum had a good article about the VTOL startups:
