Overview ²


  • P-9 Pober Pixie
  • Role: Recreational aircraft
  • Manufacturer: Acro Sport (plans)
  • Designer: Paul Poberezny
  • First flight: July 1974

The Pober Pixie is a single-seat light aircraft that was designed in the United States in 1974 and marketed as plans for homebuilding. It is a conventional parasol-wing monoplane with fixed tailwheel undercarriage and a single open cockpit. The design was inspired by the Heath Parasol.

Development ²


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 fuel consumption of 3 to 3.5 US Gal (11 to 13 liters) per hour. Plans were completed in January 1974 and the prototype flew in late July, in time for the EAA Annual Convention that year.

After the convention, the prototype was returned to the shop for minor improvement work, including installation of a Limbach SL 1700 EA engine (60 hp at 3,550 rpm) and Rehm 5330 two-blade fixed-pitch propeller. The improvements were incorporated into the plans.

Design ²


The Pixie fuselage is fabricated from welded 4130 steel tube, while the wings are made from spruce covered with poly-fiber fabric. Recommended engines include Volkswagen or the Continental A-65.

The design includes full-span ailerons that give it a high roll rate with minimal adverse yaw. Aircraft Spruce and Specialty says of the design: “Similar in many respects to the Heath Parasol, the Pixie is a modernization of the helmet and goggle days of the 1930’s. The large wing and full span ailerons make for easy flying. With minimal taildragger experience, the Pixie is a breeze to handle on the ground. Landings are gentle affairs, visibility in cruise is outstanding and using it with skis adds another dimension of fun.&rdqup;

Variants ²


Pober Pixie II: Paul Poberezney had some drawings and started some welding of a fuselage for a two seat model. Micheal Hoye bought the project, and completed a single scratch-built example of a two seat Pixie in 1999.
