Ozone Delta 4 MS

The Ozone Delta 4 MS is a high-performance EN C paraglider designed for intermediate to advanced pilots with SIV experience who fly 70–100 hours per year.
The “MS” size specifically targets pilots with a total flying weight (all-up weight) between 75 kg and 95 kg.

Technical Specifications (Size MS)
According to technical data from Ozone Paragliders and Flybubble, the MS model features the following characteristics:

Weight Range: Certified for 75–95 kg; Ozone recommends a flying weight of 82–94 kg for optimal performance.

Glider Weight: Approximately 5.01 kg.

Dimensions: Flat area of 23.1 m², flat span of 11.83 m, and a root chord of 2.46 m.

Aspect Ratio: Features a flat aspect ratio of 6.05, which is relatively low for its class to maintain high passive safety.
Cell Count: 66 cells.

Key Performance Features
The Ozone Delta 4 introduced several technological advancements over its predecessor, the Delta 3:

Active Control Risers (ACR): Inherited from the Mantra series, this system allows full angle-of-attack control on the B and C risers without deforming the wing profile.

3/2-Line Layout: Uses a 3-line layout in the center and a 2-line structure at the tips to significantly reduce drag.

G-String Technology: Small fabric strips in the center of each cell reduce vibrations and maintain the leading edge shape during accelerated flight.

Speed & Glide: It is roughly 3 km/h faster at top speed than the Delta 3 and offers a 12 cm/s sink rate advantage during full-speed glides.

Pilot Experience & Reviews

Handling: Reviewers from Dust of the Universe note that the MS size has a “subtle feel” and is more communicative about airmass than previous models.

Stability: According to Cross Country Magazine, the wing is highly resistant to collapse even at full speed and exhibits some of the mildest post-collapse behavior in the series.

Ease of Use: It is often recommended as a first “C-wing” for pilots moving up from the EN B category due to its high levels of passive safety.

Purchasing Options
The Ozone Delta 4 is currently considered a past model by some retailers as newer versions are released.
