About the Extra Flugzeugproduktions- und Vertriebs-GmbH Extra NG

The Extra NG represents the next evolution of Germany's legendary Extra Aircraft aerobatic lineage, combining the precision handling that made the Extra 300 a world aerobatic champion with modern composite construction and improved efficiency. Built by Extra Flugzeugproduktions- und Vertriebs-GmbH in Dinslaken, Germany, the NG entered service in the early 2010s as a two-seat, single-engine aerobatic trainer and sport aircraft capable of unlimited aerobatics including sustained inverted flight, lomcevaks, and snap rolls at competition-level G-loads.

Powered by a Lycoming AEIO-540 six-cylinder engine producing 315 horsepower, the Extra NG achieves a never-exceed speed of 245 knots and a roll rate exceeding 400 degrees per second, making it one of the most agile certified aircraft in the world. Its carbon-fiber fuselage and wings keep empty weight below 1,400 pounds while maintaining a +10/-10G ultimate load factor, and the type's symmetrical airfoil performs identically upright or inverted. The NG features side-by-side seating rather than tandem, making it popular for aerobatic instruction and cross-country sport flying, with a useful load sufficient for two occupants and fuel for 500-nautical-mile legs.

While the Extra 300 dominated unlimited aerobatic competition through the 1990s and 2000s, the NG targets the advanced training and sport aerobatic market, offering gentler handling characteristics than its razor-edged siblings while retaining full competition capability. The type is certified under both FAA Part 23 and EASA CS-23 in both the aerobatic and utility categories, with a clean stall speed of 61 knots and flaps-down stall at 54 knots providing docile low-speed handling between aerobatic sequences.
