Isn't it about time Reno introduced an electric class

I know this is electric airplane posting, but what about a Turbine Class while were at it.

"A partnership led by Rolls-Royce is building an all-electric aircraft that may smash into the record books with a top speed of over 300 mph (480 km/h) – beating the previous record of 210 mph (338 km/h) set in 2017 by Siemens."

Electroflight and YASA have been working on this for a good while. Cool to see a big company like Rolls Royce getting into the mix.

Racing is valuable as an R&D testbed. Air Race E could kick off a new Thomson-style era of air racing if they play their cards right. If you can pit different electric motor and battery manufacturers against each other, you have created a lot of sponsorship opportunities for race teams and the race event as a whole.

The magni500 all-electric motor 750hp

This will give you an idea of how the future will sound.

Quieter aircraft will be great for doing away with all the silly noise complaints around airports.

But for racing I know there's always a desire for particular sounds. Well if it's a dealbreaker for people, I'm willing to sacrifice some weight and battery capacity so I can power a speaker to make V12 or Radial engine sounds.

The motor in the video I posted is only 750Kw about 1005 bhp

When they have unlimited electrics running I would expect five times the power, possibly with multiple motors.

If you have a pack of eight of these aircraft flying towards you at 500mph, I think you would be impressed.

Battery technology is still the limiting factor. That 750hp motor will only yield 30 minutes of range with a battery pack that weighs nearly a ton.

30 minutes. Thats about the correct length of time for a race. I dont see any problem making a plane which can carry a ton of batteries. The only concession is that I think the planes will have to start the race on the ground so that, they dont have to wait around before the race , reducing their available power.

I think you need a maximum battery weight rule to keep the costs down, and for safety a wing loading rule, otherwise try to keep the rules as open as possible to encourage interesting designs.

Over the years I expect improvements in batteries to allow more power each year, so there should be records broken every year.

For comparison the Tesla Model S car battery is described below :-

The 85 kWh battery pack weighs 1,200 lb (540 kg) and contains 7,104 lithium-ion battery cells in 16 modules wired in series (14 in the flat section and two stacked on the front).

The max takeoff weight of a Sea Fury is 14,650 lb (6,645 kg) with around 2,500 hp

That's not 30 minutes at 100% power though. Push it all out in race trim and you'd be lucky to get 10 minutes of run time.

We (Electric Falcon) are planning for a 5 minute race plus a safety buffer for cooldown and landing. Already got the motor turning and working through battery pack design.
