Interesting looking machine. They say it flew unmanned, I'd like to have some video of that!
It deffinetly looks cool! But I wish thwy would go with the Self Rotating Single Wing,It's safer if you loose a Motor you can still land without relying on Autorotation alone?I don't think those tilt rotors can autorotate at all?

Here's the lady who is the CEO of McDonnell-Douglas Helicopters. That's a cool looking helicopter.

But it certainly can glide to the ground.
But not from all the whole flight envelope - it'll have a large H/V curve where a failure = crash. The other thing to consider with that particular layout is an asymmetrical loss of thrust.

Not a big deal on an unmanned drone, different story on something intended to carry people.

I would guess, but don't have any information to prove this, that there is a driveshaft between the two motors such as that found on the V-22 and AW-609.

Nope - per their press release no transmissions or swashplates.

If they locate a single motor between the two counterrotating rotors they can get a 2:1 reduction simply by driving one aero-rotor from the motor's rotor (shaft) and the other aero-rotor from the motor's stator (frame).
