Acro Sport II
These figures describe a typical build. Each aircraft of this design was built by its owner, and the one you are looking at may differ.
The Acro Sport II is Paul Poberezny's two-seat development of his single-seat Acro Sport biplane, an EAA design sold as plans since the late 1970s: a welded steel-tube fuselage and wooden wings of 21 ft 8 in span, 875 lb empty and 1,520 lb gross, with a 180 hp Lycoming O-360 giving 123 mph cruise, a 53 mph stall and 1,200 fpm.
It is the sensible aerobatic biplane: Pitts-like construction with a wider fuselage, two seats so the owner can take an instructor or a friend, and handling that is sporting without being as demanding as a Pitts; the trade is a 105-knot cruise with an open cockpit. Plans-built over four decades, so each example is its builder's: welding, wing-spar wood, rib condition and fabric are the inspection items and the builder's log is the history, and engines from 150 to 200 hp have been fitted with the weight following. Tailwheel biplane landings, with the nose hiding the runway, are a skill to be current in. The owner may maintain it and the condition inspection needs an A&P or the repairman certificate; plans and parts remain available from Acro Sport Inc.

- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
