Ernest, you pr= etty much said it all.

Let me just add a few thin= g.

Since you have pretty much everything double, s= o are possible failure sources.

Why counter rotat= ing propellers? Is there a power density issue?

W= ould have to spend millions and millions to getting that into the air.

There is a= lot more to it!

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