Detailed description
"Rid'Air Team's opinion: The AirDesign RONIN-Bi embodies freedom and adventure without compromise. This ultralight single-surface tandem, weighing only 2,6 kg, is a true revolution for extreme hike & fly and mountaineering. We were amazed by its compactness, its ease of setup even on technical take-offs, and its agile and precise handling. It's the perfect wing for experienced tandem pilots looking to push boundaries, explore wild terrain, and share unique sensations off the beaten path. The RONIN-Bi is the promise of flying together, without rules, just for the joy of exploration."
From the Manufacturer
The RONIN-Bi is AirDesign's new single-surface tandem, directly inspired by the Ronin spirit: compact, light, and agile. Weighing only 2,6 kg, it positions itself as the lightest tandem on the market, opening up unprecedented possibilities for two-person flight in high mountains, climbing, and alpinism. Its design represented a real challenge, particularly in ensuring a structure capable of withstanding 1 500 kg of load for over 3 seconds, while maintaining a featherlight weight. Thanks to the experience gained with the UFO Bi, the designers have optimized its extreme compactness, generous arc, and agile turning. The tauter profile ensures quick lift-off at launch and a comfortable landing. The reduced line set facilitates pre-flight checks, and a deliberately more resistant fabric guarantees durability and strength. The RONIN-Bi is designed for those who prefer to explore their own paths.
