About the Performer
Marek Choim was a Polish aerobatic pilot renowned for hard-charging freestyle routines in the Extra 330SC. His daytime shows blended high-energy gyroscopics, tailslides and rapid rolling figures with precise showmanship.
He also flew a colour-smoke routine, streaming plumes from the wingtips and wheel fairings to “paint” loops and rolling circles across the sky. After dark, Marek’s pyrotechnic night display mounted fireworks on the wings and gear spats for a dramatic light-and-smoke spectacle.
Marek appeared widely across Poland and internationally, including Leszno, Świdnik and Radom. In mid-2024 he announced his retirement from airshows, closing a chapter of vivid, high-impact displays.
About the Extra 330SC
Type & role. The Extra 330SC is a single-seat, unlimited-class aerobatic monoplane designed by Walter Extra. The “SC” (single-competition) variant is optimised for maximum performance.
Construction & performance. Carbon-fibre wing with steel-tube fuselage; powered by the Lycoming AEIO-580 (~315 hp). It is certified to approximately ±10 g with a Vne ~ 220 kt. Typical roll rate is around 420°/s, enabling aggressive gyroscopics and fast hesitations.
Marek’s mount. His Extra 330SC was registered SP-GII (c/n SC082), a 2019-built airframe used throughout his late-2010s/early-2020s display work.
