The A-2 Seaplane was an unbuilt 1915 design.
The one Sturtevant A-3 Battleplane was built in 1915. Only one recorded flight was made, at nearby Readville Trotting Park in December 1915. The wingspan was 47’0″ and length 25’10”.
Stupar 1914 Biplane 2 / Chicago Aero Star Tractor
In 1914 Max F Stupar designed and built two single place biplanes as exhibition ships for Earl Daugherty. The first was powered by a 75hp Curtiss OXX-5, and also a 60hp Kirkham 6, the second one with 50hp Gnôme rotary.
Similar planes were also built for Victor Carlstrom, William Couch, Robert Shank, and other local notables, some likely produced as Chicago Aero’s Star Tractor.
Stupar 1914 Biplane 1
The Stupar 1914 Biplane 1 was Stupar’s first construction while employed by the Aero Works, this one for Hillery Beachy.
The single-place biplane was powered by a Hall-Scott engine, and also a Kirkham 4. A six-wheel undercarriage was fitted.
Stull Lucky Stars
Mark Stull built Lucky Stars with a 4.5-foot-diameter ring tail. It took some clever engineering and some hair-raising test flights to make it work. Stull added a hydraulic damper to ensure that the tail didn’t swing too far to the side, and balanced the tail by adding weights to the ring. He then moved the seat forward to maintain the craft’s centre of gravity.
