Kitty Hawk reveals its secret project, Heaviside

I'm encouraged to see proper wings and empennage, glad you're not making an octocopter. Bonus points for conventional (tailwheel) landing gear.

But questions:

How fast can it fly and for how long?

Article says "weighs about one-third of a Cessna". So less than 1000 lbs empty?

And, importantly, with those wings, does it "stall" normally, at 40 mph or so?

Asking as a former J-3 Cub pilot who'll assuredly never afford this.

Proper but forward-swept wings, which mean you won't be able to fly this without substantial computer assistance.
