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.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".Variants
