UFO HeliThruster and IFR?

Yes, I confess. I don't know much about rotorcrafts. Especially 
regarding gyrocopters my knowledge is even more limited.

However, on the net I just stumbled over UFO HeliThruster. Rumors are 
that it is rather stable. The manufacturer not only sells kits but also 
(FAA-?) certified planes.

If I would buy such a certified HeliThruster, fit it with the necessary 
instruments, and give it an N-registration, would I be allowed to fly it 
IFR given that I had the necessary pilot certificates? Would I be 
allowed to fly it outside US?

Thank you for sharing your knowledge!
