Background
Origins
Acro Sport was founded by Paul Poberezny, the influential aviator and founder of the Experimental Aircraft Association (EAA). Designed in the early 1970s, the Acro Sport series emerged from Poberezny’s desire to provide homebuilders with straightforward, plans-built aerobatic biplanes with proven performance.
Rise and Expansion
The Acro Sport I plans were released in the 1970s, followed by the larger two-seat Acro Sport II. Both designs attracted a loyal builder base thanks to detailed plans, wooden wing construction, welded steel-tube fuselages, and compatibility with a range of engines. Their performance made them suitable for sport aerobatics, flight training, and recreational flying.
Key Aircraft
- Acro Sport I – Single-seat aerobatic biplane known for strong roll response and traditional styling
- Acro Sport II – Two-seat variant suitable for training and dual instruction
Both aircraft remain popular within the homebuilt community and are often seen at fly-ins and aerobatic gatherings.
Modern Status
Acro Sport, Inc. operated for decades as the distributor of plans and builder support materials. Today the aircraft remain plans-built designs, with active builder networks and many flying examples maintained by private owners.
