Fabric and colour resistance

Please be aware that the colour you see on your screen may not accurately represent the actual fabric colour. Given the wide variance in monitor calibration and the fabric appearance in different light and colour combinations, it is impossible to perfectly represent fabric colour on the screen. If you have any doubts about the colours, look at photos of various wings on the website to see them in different light and colour combinations or contact Flybubble to see the fabric in person.

All of the fabric that Ozone use undergoes extensive testing in prototype colour phase to ensure colourfastness, mechanical stability, porosity, and general longevity before they put it into production. Once the fabric is in production, every meter of it is rigorously inspected upon arrival in the Ozone factory, and fabric which does not pass the stringent quality control standards is returned to the manufacturer. All of the colours that Ozone manufacture score between 4 and 5 on a scale of 1-5, with 5 being the highest possible rating for longevity.

Mantra M7: Performance / Competition EN D

• Next-generation 3-liner
• Combines features of Enzo 3, Zeno, and Delta 3
• Near-Zeno performance
• 3-line design that competes with 2-line comp wings
• Replaces M6 with improved safety, handling and performance
• Innovative new riser-control system

With ZENO & ENZO 3 technology

The profile, planform, and arc are all evolved from the Zeno, and the aspect ratio is a more moderate 6.5. The M7 offer a level of agility, comfort and safety closer to the Delta series, with near-Zeno glide performance. Most importantly, it is an incredibly fun wing to fly! This new design replaces the M6, and bridges the gap in the Ozone range between the Delta 3 and Zeno. It is a significant step up from the M6 in terms of performance, especially in accelerated flight, but with better collapse recovery characteristics, reduced pilot workload, and more cohesion in turbulent air. It is the ideal wing for experienced pilots stepping up to the D class who want the performance and pleasure of a modern 2-liner, but with more comfort, security, and confidence.

Technology

The Zeno-inspired profile, with A-line attachments set relatively far back from the leading edge, creates a strong & collapse-resistant nose. You can push hard through turbulence and gain lift in each gust. The Internal structure is optimised for weight and cohesion. The wing absorbs turbulence without chord or spanwise deformation, meaning that the handling can be exploited at all times, even in the strongest, roughest thermals. The cohesion of the sail, coupled with this solidity, is confidence-inspiring. It reduces the demands on the pilot allowing you to use the full XC potential of the day. A new riser control system allows full control in accelerated flight. Acting on both the B and C risers, this innovative system offers a direct, efficient angle of attack control without deforming the profile. The intuitive feel and feedback from the risers allow the pilot to maintain the solidity of the wing while accelerated in turbulent air.

The class

The M7 is certified EN D and aimed at EN D level pilots, even if the certification grade is mainly due to the use of collapse lines. The level of comfort and security is closer to the class below. Collapse lines were used because Ozone was totally unwilling to weaken the structure of the wing just to achieve a lower EN grade. True Performance in real conditions remains the first priority. Extensive collapse testing has shown excellent recovery behaviour - better than the M6, with less tendency to cravat.

The pilot

The M7 is for advanced pilots who are progressing to the highest levels of XC flying. It is ideal for competent pilots stepping up from a lower grade, or those wishing for easier, more benign behaviour than a 2-liner without sacrificing performance. It’s recommended for experienced pilots who fly at least 100 hrs per year, with recent SIV training. The M7 is undoubtedly the best 3-line wing Ozone have ever produced. After an extended period of testing in very strong conditions, Ozone is very pleased with the end result. It is a powerful wing with True Performance at its heart; an accessible feel, agile handling, and high levels of security.

Designer's notes

• A completely new 3L design, mixing ingredients from the Enzo 3, Zeno, and the Delta 3.
• The general idea was to give the 3L design a new chance to compete against a good two-liner competition wing in term of performance, control and pleasure.
• The riser control while on the bar, and even at full bar, is direct with no profile deformation and perfect feedback, thanks to an innovative riser handle and speed system.
• Performance is equal Zeno at trim speed and very close to Zeno at full speed. Solidity at full speed is the best Ozone ever made on a certified 3 liner.
• A pleasure to fly and thermal is the best Ozone have had in the Mantra series.
• The behaviour in collapses is amazingly nice.
• The feedback of the wing is intuitive and comfortable.

Mantra M7 IMPORTANT NOTICE: Inverted Leading Edge

After investigation of the Mantra M7 leading edge lower surface deformation, Ozone now have a clear understanding of the phenomenon.

Under certain specific circumstances, the leading edge plastic reinforcements may remain inverted on the lower surface, even during flight. This is created by a lack of tension in the middle part of the leading edge during the inflation process. If the wing tips are allowed to inflate before the middle section of the wing, the plastics in the centre may become inverted and can remain so even once in the air. When it occurs, it normally only affects the central part of the wing span and whether it occurs at all depends entirely on how the wing inflates.

This situation can be avoided with good inflation practices. Always ensure the wing is in a good position before inflation. When launching in wind, make sure the wall is well built with the middle section higher than the tips. In nil-wind conditions, lay the wing in a pronounced arc so the middle is more likely to rise before the tips. Ozone recommend to only hold the central A risers during the inflation process – there is no need to hold the outer riser to which AR3 is attached. Whatever the wind conditions or launch method you use, always ensure the middle of the wing inflates first, like this the phenomenon should not occur.

If you do find yourself in the air with inverted plastics, do not worry; the wing can be flown as normal. Ozone testing has shown it is not a safety concern, the wing can be flown perfectly safely and can always be remedied in-flight. To do so, use a short, sharp symmetric jab of the brakes. The action is not the same as the input used to recover from a collapse a deep long pump is generally not effective – rather, use a shorter, sharper, harder input to provoke the plastics to right themselves. When jabbing the brakes like this, push your hands to the outside, that way the central brakes are engaged early, this is the most efficient technique to encourage the plastics to pop in the very middle of the wing. When using this method, Ozone has found the plastics can be righted 100% of the time, Ozone has never been unable to right inverted plastics whilst in the air.

Ozone has conducted a thorough flight test procedure with the plastics inverted and have not experienced any significant detrimental effects on the behaviour of the wing. Parachutal stalls are unaffected, the wing enters and exits a parachutal stall in the same way whether with the plastics inverted or correctly orientated. Collapse recovery is also unaffected.

Theoretically, with the plastics inverted Ozone believe there will be a slight impact on performance so you should input the wing as soon as it is safe to do so (when tow launching wait until you have released). However, even with the plastics inverted, the M7 can be thermalled and ridge soared as normal and when flown actively can still remain open in strong turbulent air.

Please watch the video below for a clear visual explanation and if you have any questions do not hesitate to contact one of the Ozone test team.

Flybubble review

"The Mantra M7 offers lower pilot demands than the M6, so it fits well in Ozone's range, midway between the Delta 3 and the Zeno. The M7 inflates fairly readily, considering the size of the cell openings, which are narrow. It's pretty typical for this level of wing. So getting the wing open and building a wall in moderate to strong winds is as expected. On inflation, it requires a pretty high level of control on giving correct and symmetric input. I'd say the ground handling is about right for the level of wing it's meant to be, low D. It's less demanding to ground handle than most 2-liners, but more demanding than most 3-liners I've tested in recent years.

I mean the feeling you get from the wing in turns, through the breaks and rises as a result of your inputs, the energy it transmits back to you, and also how much it makes you smile. The joy factor. I find the brake pressure on the M7 moderate, if anything, slightly on the firmer side, in relative terms. The feeling in terms of the handling and energy is moderate, slightly dampened. The glider responds steadily to break inputs. It's neither particularly agile nor slow. I tested the wing at different loadings for comparison, including near the top of the weight range. If I flew the M7, then I would it fly near or at the top of its weight range, because I prefer a wing that's more dynamic and agile rather than more docile and placid. The feedback from the M7 is rather dampened for a D wing. It's very pitch stable, which leads to a slightly vague feeling. Functional rather than pleasurable. The M7 is calmer than the M6. It climbs well, good for the class. However, despite flying near the top of the weight range, I found the wing was hanging back on entering thermals. I felt the M7 climbs pretty well in light to moderate thermals, but it felt like it was more suited to stronger, punchier climbs than the weaker stuff. Unusually for a D wing, I was always feeling like, "Come on, give me a bit more speed, more energy, more feedback."

So who's this for? Uh, I see the M7 as being mainly a stepping stone wing for progressing competition pilots who are frustrated at being outgunned on their old EN-C wing by high end 2-liners, but they don't want to take the jump up to a wing like a Zeno or a Gin leopard. Overall, I'd say it has low D pilot demands in terms of ground handling, general flying, and SIV. Turns seem pretty average for the aspect ratio, if anything the wing lacks a bit of speed and energy for the class. If you're not obsessed wit performance, and you're looking for a wing that is coordinated, comfortable and reassuring, solid on full bar, then the M7 might suit you."

Other reviews

"This would be my go-to wing if I lived in the mountains. The M7 bears similar hallmarks to the King: it creates a fork in the road for pilots wanting to progress from Cs. Despite Cedar’s experience, which I respect, I’m still convinced that if you want to race, and race hard, you need to buy a two-liner and go and SIV it until you’re totally comfortable with it, because two-liners are simply the best machines to compete on. Anything else is a compromise – but I accept the M7 is a very, very good one.

Competitions aside, if you’re an XC head looking for the best wing to keep you smiling from sunrise to sunset on an epic 10-hour Brazilian chase for your personal best or a huge Alpine triangle, the M7 is a great choice. With some adjustment to your flying style, it’ll please the retiring competition pilot and put a huge grin on C pilots’ faces too."
