Ernest, you pretty much said it all.

Let me just add a few thing.

Since you have pretty much everything double, so are possible failure sources.

Why counter rotating propellers? Is there a power density issue?

Would have to spend millions and millions to getting that into the air.

I have been there done that at a much simpler scale, with just one rotor, all the way to safely fly it in my 700lb airplane.

 

There is a lot more to it!

Subject: [FlyRotary] Interesting "Twin Pack" Rotary Demo Idea

 

An aero-engineer on the VANS Alternative Engine list posted his dream project on creating a Twin Pack single rotor to put in an RV-8.  Some very creative thinking to bring it along this far IMO!
