Recognition (WEFT)
| W — Wings | Mid-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |

WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- two-seat biplane with staggered wings and I-strut interplane configuration
- open tandem cockpits with exposed cabane struts
- round cowling housing a Lycoming engine
The staggered biplane wings, open tandem cockpits, I-strut interplane bracing, and fabric covering are characteristic.

History
Paul Poberezny of the EAA designed the original Acro Sport as a single-seater, and the two-seat Acro Sport II followed with first flight in 1978. Plans were made available through the EAA, making it one of the most widely built aerobatic biplanes among homebuilders. Lycoming engines of 150-200 hp are standard.
Variants
The single-seat Acro Sport I preceded the II; both are plans-built designs with no factory kit.
Where you'll see it
