03/31/2008. Remarks by Walter van Tilborg: "Mr. Edward C. Hoffman, an interior decorator from St. Petersburg, Florida, USA, built this single-seat light (empty 616 lb, 279 kg) sport plane powered by a 65 hp Continental A65 horizontally-opposed four-cylinder air-cooled engine. After a year of construction the aircraft was completed at the costs of $ 968 and the first flight was made on February 24, 1960. Later the 65 hp A65 engine was replaced by a 90 hp C90 engine. Mr. Hoffman was a very busy builder and apart from the X-1, he created at least 4 other single-engined aircraft, including: X-2 "Little Orphan Annie", two-seat amphibian, 1962, N9159R c/n 1 X-3 "The Girl Friend", single-seat landplane, 1976, N14647 c/n 1 X-4 "Mullet Skif", two-seat flying boat, 1980, N5597N c/n 1 X-5 "Seabird", single-seat amphibian, 1991, N7182P c/n 1. I had the pleasure of meeting Mr. Hoffman and his wife many years ago during a visit to Holland. As far as I know, the X-1, X-3, X-4, and X-5 are kept in excellent and airworthy condition by Mr. Hoffman's son."
