Span 27', length 22'. powered by 90 hp warner Scarab as 1929 safety palne entry with a variable-airfoil wing (no two ribs are alike) controlled by a lever in teh cockpit. No fin or stabilizer, which were replaced by alarge, moveable stabilator and a longitudinally-adjusteable 50# weight on a track to shift the c/g. All this resulted in enought stability problems to cancel the project. It was reported that this aircraft was flown several times by Charles Lindbergh. Circa 1928-29 JMF Haase collection via San Diego AeroSpace museum This photo is from the J.M.F. (Joseph Malta F.) Haase collection, courtesy of the San Diego Aero Space Museum. J.M.F. “Bunny” Haase was a Navy Chief photographer who documented all the aviation activities from the early 1920 through the early 1930s at North Island that at the time encompassed the Army’s Rockwell Field and NAS San Diego. His large collection also covers civilian and Army aircraft as well. His air-to-air photographs are featured in many aviation reference books but usually under the credit line of US Navy. Chief Haase also participated in the second Alaskan Aerial Survey in 1929 and was responsible for the first US motion picture of the sun’s eclipse done in 1930 that was done from an aircraft.
