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.

Looks
like an electrified Sparrow-Hawk.

First link has some content, if you scroll down. At least for me.

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.
