The Ozone Mac Daddy Bi (or McDaddy) is a French two-place paraglider that was designed by hang gliding and paragliding world champion pilot Robbie Whittall and produced by Ozone Gliders of Le Bar-sur-Loup. It is no longer in production.[1][2]

Design and development

The aircraft was designed as a tandem glider for flight training and as such was referred to as the Mac Daddy Bi, indicating "bi-place" or two seater. It replaced the Ozone Cosmic Rider in the production line.[1][2]

The models are each named for their approximate wing area in square metres.[1]

Operational history

Reviewer Noel Bertrand described the Ozone series of gliders in a 2003 review as, "wings that are both pleasant to fly and high performance in their respective categories".[1]
