Ozone Delta 4 ML

The Ozone Delta 4 ML is a high-performance EN-C paraglider designed for intermediate to advanced cross-country (XC) pilots who fly between 70–100 hours per year.It is specifically engineered to bridge the gap between B-class wings and advanced competition wings by offering “two-liner control” with the comfort of a three-liner design.

 

Technical Specifications (ML Size)
According to the manufacturer’s technical data from flyozone.com, the ML size is optimized for mid-range pilot weights:

Certified Weight Range: 85–105 kg.

Recommended Flying Weight: 90–104 kg.

Glider Weight: Approximately 5.26 kg (5.3 kg listed in some specifications).

Flat Area: 24.4 m².

Flat Aspect Ratio: 6.05.

Number of Cells: 66.

 

Key Performance Features
The Ozone Delta 4 introduces several innovations developed from high-end competition series like the Mantra and Zeno.

3/2 Line Hybrid Layout: Features three lines in the centre but transitions to two lines at the wingtips, significantly reducing drag.

Active Control Risers (ACR): Inherited from the Mantra M7, this system allows for direct, efficient control of the angle of attack using the B and C risers while accelerated.

Sink Rate Advantage: According to performance tests on flybubble.com, the Delta 4 has a 12 cm/s sink rate advantage over its predecessor, the Delta 3, during full-speed glides.

Ozone G-String: Small fabric strips in the cell centres reduce leading-edge vibrations and help maintain the airfoil shape at high speeds.

 

Pilot Experience & Reviews
Experts from Cross Country Magazine and Dust of the Universe highlight the wing’s balance between accessibility and high performance.

 

Ease of Use: Reviewers on xcmag.com describe the wing as “nicely planted and calm,” making it suitable for pilots moving up from a high-end EN-B wing.

Handling: One tester from Dust of the Universe noted that the ML size exhibits a very “coordinated and smooth turn” with surprising agility for its size, effectively cutting through turbulence to gain altitude.

Safety: The wing features a Shark Nose profile that makes it highly resistant to spins and stalls, simplifying landings in tight spots.
