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]
