A mileage machine for cross-country flying. Launched in January 2025, the 5th generation of the Delta offers access to 2-line technology without sacrificing comfort or passive safety. Our full analysis, tested in the thermal aerology of the Cheiron.
Ozone Delta 5 · EN-CThe Ozone Delta 5 marks the arrival of a new generation in the EN-C 2-liner wing family. Launched in January 2025, this 5th version is aimed at intermediate to advanced pilots who want to access 2-liner technology without sacrificing comfort or passive safety. Firmer on the brakes than the Delta 4, but significantly more performant.
The Delta 5 was designed for the pilot who has a few cross-country seasons under their belt and is looking for a wing capable of'to cover the miles with peace of mind : improved stability in turbulent conditions, excellent sink rate in light winds, and reassuring handling during accelerated flight. It never outpaces the pilot, climbs easily and is more manageable than most wings in its class.
At Accessories, we have been familiar with the Ozone range for years. Our instructors fly daily at sites in the Alpes-Maritimes, where the thermal conditions of the Cheiron putting each sail to the test.
It’s in the air that the Delta 5 really impresses. Here’s what it offers, from thermals in the Cheiron to accelerated flight on transitions.
High precision when utilising lift: the wing centres easily, remains stable in the core and does not stall during transitions. Its drop rate in light winds is very good — it stays airborne where others lose lift. It climbs quickly, even in calm conditions, without the need for constant active control.
The area where the Delta 5 has progressed the most has been its progressive and efficient accelerator, with a solid high-speed profile. You can keep the bar pressed without the wing becoming nervous. Every bit of glide gained at 45-50 km/h translates into kilometres supplémentaires at the end of the day.
Direct and precise cornering. The steering, firmer than on the Delta 4, brings best inflight information. Rear-wheel steering – fundamental on a 2-liner – is particularly intuitive. Simple inflation, decisive and predictable landing. To read the conditions, see our guide Meteoblue.
The Delta 5 is not a simple cosmetic facelift. The generational gap is significant enough to justify a wing change, even for a pilot happy with their Delta 4.
Ozone has undergone a major overhaul: new aerodynamic profile, optimised 2-line architecture, redesigned materials for increased strength without adding weight. Moderate elongation (guaranteeing accessibility), refined risers and cut-out to reduce drag. The risers facilitate rear-flying control, and packing remains compact with the Concerto bag.
Compared to the Delta 4, the Delta 5 is firmer on the control (feeling direct, informative), more performant in accelerated mode (high-speed finesse), More stable in turbulence (spontaneous re-openings, little loss of altitude) and, paradoxically, more docile in strong conditions. She does not overtake her pilot.
Often presented as the ideal entry point into the world of 2-line kites – provided you don't skip steps and have a solid foundation.
A pilot flying a Rush 6, Swift 6 or equivalent EN-B+ wing can consider the Delta 5 with 150 to 200 hours of active flying understand aerology, exploit mountain thermals, manage turbulent air, master rapid descents. Our courses accompany this upskilling.
The pilot already flying under EN-C 3-liners and wants to move to 2-liners without increasing the piloting requirement gains in accelerated finesse and sink rate, with superior comfort. A versatile wing (local flying, soaring, first light acro approaches) that can do it all.
Six sizes., PTV 60 to 135 kg, all EN-C certified. Profile Sharknose, high-strength fabric, sheathed risers on the main lines. Supplied with concertina bag, speed bar, repair kit and manual. Mid/upper range = manoeuvrability; lower range = stability and better sink rate.
Since the launch, feedback from the community and testers has converged on several points.
Ziad Bassil (Dust of the Universe) highlights its solidity in strong conditions and ease of inflation: «never outpowers its pilot». Russell Ogden insists on excellence in thermal engineering. Certika France More responsive to the controls than the Delta 4 but much higher performing… a machine built for covering the miles.«
We have been working with Ozone since the school was founded. Our partner Aerotech, based at the same location as Gréolières, carries out maintenance on our fleet. The Delta 5 embodies what Ozone does best: making high performance accessible without compromising on safety. See also our review Ozone Alta.
The base price is between €4,200 and €4,800 depending on size and options (indicative price). All sizes are available from January 2025. Before investing, a test flight is highly recommended.
At Gréolières, our partner Aerotech — Ozone sales and repair specialist — will guide you on the ideal size according to your profile and your PTV. Contact us to arrange a trial.

Evolutions, required level, two-line, sizes, price, trial: the concrete answers after our field test.
Not a simple facelift: new profile, optimised 2-line architecture, reimagined materials. In flight, the Delta 5 is firmer on the control, more performant when accelerated, more stable in turbulence and more docile in strong conditions. The generational leap justifies an upgrade even for a pilot happy with their Delta 4.
Intermediate to advanced, with a few seasons of cross-country flying. Two profiles: the pilot coming from a high-performance EN-B (Rush 6, Swift 6, etc.) with 150 to 200 hours of active flying, and the confirmed EN-C pilot moving to a 2-liner without increasing piloting demands. Our courses preparing for this transition.
A 2-liner has only two rows of risers (instead of 3-4), which reduces drag and improves glide—technology from competition. The certification English (UK) corresponds to a high-performance wing requiring active piloting. The Delta 5 allows smooth access to this, with intuitive rear-riser piloting.
Yes, without rushing things. You need a solid foundation: understand aerology, exploit mountain thermals, manage turbulent air, master rapid descents (ear plugs, committed 360s). A pilot with 150 to 200 hours regular active involvement can reasonably consider it.
Six sizes, PTV of 60 to 135 kg, all EN-C certified. Mid/upper end of the range = more manoeuvrability and responsiveness; lower end of the range = more stability and better sink rate, with slightly softer controls. Check the exact values on the Ozone website before purchasing.
Base price between €4,200 and €4,800 Subject to size and colour options (indicative price, variable by retailer). Supplied with Concerto concertina bag, speed bar, repair kit and flight manual. All sizes available from January 2025.
We strongly recommend a test flight before making a purchase: several authorised dealers offer test flights by appointment. At Gréolières, our partner Aerotech will guide you on the ideal size according to your profile and your PTV. Contact us to discuss it.
