Hello Gerhard,
I acquired a Speed Canard SC01 with a number under 60 about four years ago. It is a terrific aircraft and, as you probably know,the entire manufacturing run is certificated in Germany, Switzerland, Australia,Taiwan, etc, but the lower numbers are not certificated in the U.S. The solution is simply to register it here as an EXPERIMENTAL/EXHIBITION craft. The limitations of this class are only apparent and do not really restrict one's ability to fly wherever, whenever one wishes.
My craft had, since its construction, been registered in Switzerland and flown mostly in Germany. Registration here was not difficult. Let me know what further information you require.
