Design and development

The Proton was designed as a competition glider. The initial version was later replaced by the Proton GT in production. The GT incorporated a partially closed leading edge, with 20 partially closed and 10 cells fully closed. The models are each named for their relative size.[1][2][3]

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]
