In response to the
1973 oil crisis, the
EAA launched "Project Econoplane" to develop an aircraft with high fuel economy that would therefore be affordable for its members to operate.
The Pober Pixie was the result, with a

Variants
;Pober Pixie II
:Paul Poberezny developed some drawings and started design and partial welding of a fuselage for a two-seat model. Michael Hoye of Heath Texas purchased the project in 1989, continued the design, and over a period of ten years completed building a single scratch built example of a tandem two-seat Pixie in 2000. This aircraft won an "outstanding workmanship" award at Airventure 2001 and was featured as the cover story by noted author Budd Davisson in the January 2002 issue of Sport Aviation magazine.
