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

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.


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.


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.
