Historical Note
The Decathlon 8KCAB was originally developed by Bellanca Aircraft Corporation in the early 1970s as a purpose-built aerobatic trainer and sport aircraft. The early Bellanca Decathlons (1970–1980) featured traditional wood wing spars and were initially powered by 150 hp Lycoming IO-320 engines, with later variants receiving 180 hp powerplants. The "Super Decathlon" designation emerged in 1975 with the standardization of the 180 hp engine configuration.
After Bellanca ceased operations in 1980, the design rights were acquired by American Champion Aircraft Corporation (ACAC) in 1989. American Champion modernized the design with aluminum wing spars, strengthened airframes, and standardized the 180 hp Lycoming AEIO-360-H1B engine with constant-speed propellers. Today's Super Decathlon represents over two decades of design refinement while maintaining the aircraft's legendary aerobatic capabilities (+6/-5g limits) and classic tandem configuration.
Both vintage Bellanca and modern American Champion variants share core features: fuel-injected engines, inverted oil systems, inverted fuel systems, and exceptional aerobatic performance. The aircraft remains popular among aerobatic schools, sport pilots, and tailwheel enthusiasts worldwide.

- Configuration: High-wing, tandem seat, conventional landing gear (taildragger)
- Bellanca Era (1970–1980): Wood wing spars, tubular steel fuselage, fabric covering, 150 hp or 180 hp Lycoming engines
- American Champion Era (1990–Present): Aluminum wing spars (metal spar conversions available for vintage models), strengthened airframe, standardized 180 hp Lycoming AEIO-360-H1B with constant-speed propeller
- Aerobatic Limits: +6/-5g design load factors for both eras
- Fuel Systems: Inverted fuel and oil systems standard across all variants
