07/21/2007. Remarks by Elmer Carlson: "This is the plane I built back in 1971. I started it in 1965 in St. Maries, Idaho and finished it in 1971. I converted a ground power unit for the engine, a 125 hp Lycoming O-290 engine.
The photo was taken shortly after I made the first flight. Dale Mumford, the FAA representative who inspected the aircraft, allowed me to put the registration number on with 2 in (5 cm) letters. He said it qualified as an exhibition airplane. After I sold it in June 1973, the new owner had to use the larger numbers as shown on page 942.
Here is the story about my first flight in N671EC."
