Given that Redbull airrace courses are under 2 minutes I think having that series go electric would be an awesome idea.

RallyX is already considering it since they are all sprint races.

It's wonderful to see a commitment to advancing electric flight.

Does sprinting to top speed take longer in a plane compared to a wheeled vehicle? I.e. is the burst of peak power required to be sustained for longer, leading to thermal problems with the battery and motor?

I ask because the targetted performance seems markedly less than some electric racing cars have, several in the 1000HP-1000kW region.

Flight performance is always dictated by (amoungst many other things)... Power and weight.
And in the case of electric aircraft, that weight is dictated by battery capacity/power ratios.
I suspect this RR design is a compromise on battery weight/discharge power, endurance, and capacity.
IE, they could have had a much more powerful drive, but the battery to support it would be disproportionately heavy.

It's interesting that they talk about how they've recruited a big experienced team for this internally important project, but the powerplant is just three YASA motors bolted together. I guess those things are hard to beat.

The must have somebody pretty smart helping them out with the battery on that one.... :mrgreen: :mrgreen: :mrgreen: :thumb: :thumb:

"You're done, we used salary to buy an electric model plane that flies for minutes . . ."

" 1,400 jobs are being cut by engine maker Rolls-Royce as it continues to slash its workforce by 9,000.

The Derby-based company has been hit hard by the pandemic with a fall in demand for its aircraft engines.

The job losses are part of those the firm revealed in May, with more than 3,000 of those in the UK."

They should reallocate those workers to the Modular Reactor development and construction team !
..or to figuring out how to modify their Aero engines run on Hydrogen !

Heck, that's nothing. Think of the millions spent on drag racers that can't run at full power for more than five seconds. Think how many salaries that would pay!
