Overview
The Extra 330SC is a purpose-built single-seat competition aerobatic aircraft designed to dominate unlimited-class aerobatic competition. Powered by a 330 HP Lycoming AEIO-580-B1A engine driving a three-blade MTV propeller, the 330SC delivers a thrust-to-weight ratio that enables sustained vertical performance and knife-edge flight with authority. Its carbon-fiber composite construction keeps empty weight below 1,500 lbs, enabling a roll rate exceeding 420 degrees per second.
Designed by Walter Extra at Extra Flugzeugproduktions- und Vertriebs-GmbH in Germany, the 330SC is the aircraft of choice for national and world aerobatic champions. Its combination of structural strength, light weight, and aerodynamic precision makes it one of the finest unlimited aerobatic platforms ever built.
History & Context
Walter Extra founded Extra Aircraft in 1980, driven by his passion for aerobatic competition. The original Extra 300 flew in 1988 as a two-seat aerobatic aircraft, and the single-seat 330 variant followed to meet the demands of top-level competition pilots. The SC (Single-seat Carbon) designation indicates the full carbon-fiber construction that reduces weight while increasing structural strength.
Extra aircraft have won numerous World and European Aerobatic Championships, and the 330SC has become the dominant platform in unlimited-class competition. The design has been continuously refined based on feedback from elite competition pilots, resulting in an aircraft that represents decades of focused aerobatic development.
Development & Updates
The Extra 330SC features an all-carbon-fiber airframe stressed to +/- 10G, providing the structural margin needed for unlimited aerobatic maneuvers. The 330 HP Lycoming AEIO-580-B1A engine is equipped with a fuel injection system and inverted oil system that ensure reliable operation during sustained negative-G and inverted flight.
The cockpit features a minimalist panel with essential flight and engine instruments, a high-visibility bubble canopy, and a five-point harness system. The aircraft uses symmetrical wing airfoils for identical performance in upright and inverted flight, and the control surfaces are designed for immediate, precise response at all attitudes and airspeeds.
Flight Characteristics
Flying the Extra 330SC is an experience reserved for the most skilled aerobatic pilots. The aircraft responds instantly to control inputs, with roll rates exceeding 420 degrees per second that demand absolute precision from the pilot. The symmetric airfoil means the aircraft performs identically upright and inverted, which is essential for competition-level flying.
The 330 HP engine provides enough power for sustained vertical climbs and aggressive energy recovery maneuvers. In competition sequences, the 330SC can snap between attitudes with a crispness that separates it from lesser aerobatic aircraft. The light weight and rigid carbon-fiber structure ensure that every input translates directly into aircraft movement without flex or delay.
Use Cases & Target Group
The Extra 330SC is designed for a specialized and elite audience:
- Unlimited-class competition aerobatic pilots at national and international level
- Professional airshow performers requiring the highest level of aerobatic capability
- Advanced aerobatic pilots progressing from intermediate to unlimited competition
- Flying schools and organizations offering advanced aerobatic training programs
- Collectors and enthusiasts seeking the finest aerobatic aircraft available
Strengths & Weaknesses
Strengths
