The RONIN-BI brings the RONIN's single-surface philosophy to tandem flying. At 2.65 kg for a 31.70 m² tandem wing, it is extraordinarily light — the lightest tandem single-surface wing available. EN-B certified for two-up flying from 120 to 185 kg combined weight. Designed for guides and instructors who want to do tandem hike & fly without carrying kilograms of extra wing weight on the approach. The RONIN-BI replaces the UFO-Bi in the AirDesign range.
