That was a cool helicopter. I saw a photo of it flying with the pilot (sole occupant) in the back seat once; Apparently he climbed in the back seat for over 4 minutes to demonstrate its stability. It was the first helicopter to be certified for IFR.

Be sure to read down far enough in that article to see the bit on the Cessna Kinedyne (it's waaaaay down there but will be interesting to gyro pilots).
