On: Kitty Hawk reveals its secret project, Heaviside

This thing must be crazy light.

I wonder how much of the advertised quietness will dissapear once it gets speced for range and passengers.

If they've solved a fundamental problem of noisy props I would be very impressed.

I see that, in horizontal flight, the propellers are behind the wing, and therefore in its wake. On the Piaggio Avanti, this arrangement creates quite noticable additional noise.
