Paul Poberezny first penciled a sketch of the Pober Sport during the summer of 1956. With a little help from his wife and brother, Paul began building the Sport with a Baby Ace fuselage and J-3 landing gear. Other EAA members pitched in to help Paul build his latest aircraft. An EAA member from Tennessee provided some partially damaged wings, which were repaired with parts from another EAA member in Wisconsin. Paul got a great deal on a fuel tank from an EAA member in Ohio and enlisted the help of a different Wisconsin member to finish painting and working on the cowling and exhaust system.
The Pober Sport was completed and ready to fly by the 1959 EAA fly-in convention. By spring of 1960, after some testing and tweaking, the Sport was ready to take on a challenge. Paul had an adventure planned for his Pober Sport that would better acquaint the general public of the capabilities of the homemade airplane and EAA. During the entire month of May 1960, Anders “Andy” Ljungberg, a Swedish engineer, toured the United States, dropping in on every EAA chapter across the country. The total trip turned out to be 13,100 miles covered in 121 hours and 25 minutes of flying time (30 days’ total duration) in which Andy visited 72 cities and each of the 48 continental United States.
Andy’s flight in the Pober Sport brought the EAA, homebuilt airplanes, and sport flying to the general public as never before. It proved that homebuilts were safe, reliable, practical machines which could be used for extended trips without an array of sophisticated equipment. The boom of EAA membership proved that the Sport’s epic journey inspired imaginations across the country.
After the cross-country tour, the Pober Sport was displayed in the EAA museum for a short time before it was sold to California residents George Walrath and Ken Bride. The airplane was returned to the EAA Museum early in 1976 and remains on display to date.
The Pober Sport was initially powered by a Continental A-80 engine, which was swapped with a Continental C-85 when the airplane made the trip to California to meet its new owners.
Paul had planned on making some plans available for the Pober Sport, but due to a lack of time was unable to actually produce them, though a simple sketch did appear in the November 1956 issue of Experimenter
. For this reason, the fine little sport plane that brought inspiration to homebuilders and united EAA members from coast to coast is a one-of-a- kind aircraft that will be enshrined in the AirVenture Museum for years to come.
