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!

With the certified probably not. With the EX-AB sure, if you can get
the DAR to write the limitations correctly.

If you do this let us know. We are always looking for a deal on good
used avionics and salvage is usually a pretty good place to look.

I did a little looking and there doesn't seem to be an FAA certified version
and for that matter I couldn't find any of them flying in the US.
