Design and development

The first drawings of the Pober Sport were published in the November 1956 issue of the experimenter.[1]

The Pober Sport is a strut-braced, low-wing, taildragger aircraft.

The fuselage is a modification of the Ace Baby Ace. The landing gear is from a J-3 Cub. The fabric covered aluminium wings are from a high-wing Luscombe Aircraft design. The elevators are controlled with push-pull tubes.[2]

Operational history

The Pober Sport was introduced at the 1959 EAA convention. During the sourcing of the parts, Poberezny used a C-47 to pick up the Luscome wings, and started work on the ailerons while in-flight.[3] Anders “Andy” Ljungberg later toured the United States on a 72 stop tour with the aircraft to visit every EAA chapter in the country. The tour was broadcast and monitored by amateur radio operators along the route.[4] The aircraft was donated to the EAA AirVenture Museum in Oshkosh, Wisconsin in 1975.[5]
