His negative stagger W-7 biplane, of original design, first flew in September 1973, after a construction period of five years and was initially fitted with an 125 hp Lycoming O-290-G engine. After it was purchased by Eura Rogers, it was completely overhauled and also re-engined with a more powerful 150 hp Lycoming O-320 and re-flown on October 14, 1992.
A second example, pictured above, was built by Brad J.H. Poling of Elk Grove, California, and although registered N99BP on September 8, 1998, it was not completed until 2001, after eight years of construction. This aircraft has an 150 hp O-320-E2C engine, and is very similar to N32E except for the N-shaped (instead of single) wing struts."
