U-Turn Infinity Explained

The U-Turn Infinity is a German single-place paraglider, designed and produced by U-Turn GmbH of Villingen-Schwenningen. It was the first glider introduced by the company in 2003 and remained in production in 2016 as the Infinity 4.[1]

Design and development

The Infinity was designed as an intermediate glider.[1]

The design has progressed through four generations of models, the Infinity, Infinity 2, 3 and 4, each improving on the last. The Infinity 4 was a complete redesign and not just an evolution of previous versions. The models are each named for their relative size.[1] [2]

Operational history

Reviewer Noel Bertrand noted the Infinity's distinctive wing graphics in a 2003 review as "easily recognizable" and noted that the design is "quick and full of promise".[1]
