Down the Rabbit Hole with Eviation's Alice
Wowsers.
Check out the skin radiators at https://youtu.be/W0DHhiwvatQ?t=104 and consider the architectural advantage of an ME-262 shark-like shape to the fuselage for headroom in a small cabin.
Props positioned to accelerate the three wake-producing areas, with [high frequency] torque vectoring because landing can be tricky. At https://youtu.be/W0DHhiwvatQ?t=145 the rendering shows two- and three-bladed props.
So what do you think? How will they look with advertising all over them?

Somebody needs to call bill lear, they stole his plane.
I think I will be optimistic/ skeptical until type certified and produced.

The Lear Jet had two turbojets on the fuselage and a T-tail. ....and a round fuselage. I'm more reminded of Scaled Composites.

LEAR FAN. Two intakes on fuselage, I believe a pair PT-6 turbo shaft inside, "Y" tail. The black engineering prototype was across the street from my old job.
Maybe your right, does have that scaled composites look.

I mean, kind of? But also not really?
SC definitely does the non-tubular fuselage thing a lot though... nothing like this either, really.

I looked at the link I provided, there was a major redesign a one point. Isn't there some disadvantage to the V-tail? Maybe compared to Y- or T-tail?
There's airframe and there's power plant. Those skin radiators need a lot of wetted area.

A V tail has less drag than a conventional tail, because there are fewer intersecting surfaces. A T tail is slightly lower drag, I think, because the intersections are farther apart? But the structural simplicity of the V tail gives it a bit of a weight advantage, maybe?
I am surprised a bit by the slim wings, and slender wing section.
The wing tip motor pods would seem to alleviate the vortex drag, I think?

I wouldn't be. If you're looking for maximum efficiency but not necessarily maximum speed.
Or high altitude and maximizing dwell time on not much fuel.

Apparently less interference drag but more wetted area required. And more complicated control linkages.
It looks like all the air sees is high-efficiency airfoils and propellers sucking any detached airflow for lunch.
