Just reposting here what is being discussed on the German forum. Looks like an electrified Sparrow-Hawk.

Here are some pictures of the maiden flight:

First link has some content, if you scroll down. At least for me. Top
level of website is https://www.byeaerospace.com/

I think they're promoting this more as an electric airplane, rather than
a motorized glider. 2000 watts isn't much to keep a two-place airplane
in the air.

Hmmm... they did work for me initially but let's try that again:

Hope these work.

Thanks for reposting the links. To me it looks like a modified Sparrowhawk
with a new, bigger, 15m wing.

Yes, 2kW is not much energy.
But consider that in high altitude that ship could need only 4-5kW to maintain a sustained flight. With clear sky and in noon you can save as much as the half of the battery's energy.

15 meter wing? Sounds like a Duck Hawk to me...

4-5KW is about 6 HP. I think 20 is a better number than 6 for sustaining.

Clear sky at noon, middle of the summer, with none of that California
smoke drifting into Colorado, and you still won't see much benefit from
that 2KW in the air (assuming they really get 2 KW). Maybe recharging
on the ground is what they're going after.

Agreed.

I thought that was a Sparrowhawk tail group and that the Duckhawk had a
different one. But, I found a Duckhawk picture just now and saw I wuz
wrong.

BTW, I thought there'd be a lot of Duckhawks flying on your side of the
pond by now, but they seem to have almost vanished without trace (just 4
registered?) despite an initial good competition showing. Why is that?

Its almost a glider... 5kW is a good number for sustained flight.
Luka´s FES system uses 4kW, you can check it out in videos and brochures.

Unless the sky is completely dead D2C-FES uses about about 2-4kW to get
maximum endurance. Doesn't climb at that but has *really* long legs to make
the most of any energy left in the sky.

Not sure all the reasons why Windard Perfromance has more or less left the US Soaring scene, but there was a lawsuit or two relating to some kind of breach of contract. I'm sure others have more accurate details. This is what I've heard while waiting in the lineup for a tow.

According to the New Atlas article, the aircraft is intended to be a drone. If the payload weighs less than a human pilot, maybe 2000 watts would be enough to sustain flight.

Nothing new. A standard 1-26 is solar powered😁

And has a TON more wing area for those solar cells to power the motor.

Good thing, too. Since it weighs a half-ton more.

Oh, now, Mark. It doesn't even weigh but about .15 tons more empty. :-)

Steve-

I was including the extra .35 tons of drag inherent to the 1-26. The 1-26 might be able to fly on solar power. On MERCURY!
