NOVA Mentor 7 Light - XS / 75-95

 



NOVA Mentor 7 Light  XS (75-95) 

Disclaimer:
As many of you know me very well, I always follow the new upcoming gliders and new releases, and in  April 2021, I heard about the Mentor 7 and rushed quickly to order one.  In this lapse of one and a half years, I received many emails asking me about that glider, but I wasn’t able to receive it…while all the magazines, Cross Country, FlyBubble, (Tests and videos on their well-respected websites), and lots of other pilots around the world got one or at least flew a demo one, of the Mentor 7 Light!  So despite my many emails, and discussions with NOVA, The Mentor 7 light didn’t arrive until today. 
I was indeed unlucky ;-) …


The tests:
Mentor 7 Light size XS flown at 92 all up. 
Again, many of you might have seen the Mentor 7 light, the construction and details are really nice with a hybrid configuration, meaning that there are a few attachment points on the C risers reducing drag, and probably NOVA was aiming for more performance, and also getting more interest for pilots who are looking to get the latest design closing the gap to a 2 liner feel…

The take-off is really easy with a moderate pull without any hard points in weak windy take-offs. In stronger wind, the Mentor 7 seems also very smooth to launch. 

That day, I shared the flight with my friends on their Swift 6 gliders. One  Swift 6 size S (65-85) flew at 84 all up, and another Swift 6  sizes MS (75-95) flew at 93 all up. I was at the same load as the pilot on the Swift 6 MS size, and it was a superb way to experience all the movements, and see the real-time efficiency of the glider in the test. 

I flew that glider in relatively strong and turbulent conditions to later weaker and smoother conditions.

I must say….The Mentor 7 Light felt like flying a tandem in the positive side of the meaning. I never felt that dampened behavior on a high B wing, and probably very close to some low B gliders in terms of ‘air information’ and roll and pitch movements. The Swift 6 feels as I test flew it is an easy and smooth glider for the high B category. The M7 light has probably twice the comfort of the S6 !! especially in moving air.  It's even more comfortable than the Swing Nyos 2 RS !!  Is it too much?  Each pilot will decide! 
There are pilots who will adore that feel, and some could reach for a more spicy feel like the Maestro 2, Rush 6, for example. Lots of different tastes for all the pilots to choose from. 
But I have to say! With this 2.5-line configuration, I think NOVA has really worked hard on the internal structure of the Mentor 7 light in order to achieve that solid and compact feel. 
After the comfortable and smooth Air Design Volt 4 as a 2-liner C glider, here’s the Mentor 7  with its 2.5 line configuration, with high comfort for a high B glider.  

The Mentor 7 light XS at 93 has a faster trim speed than a brand new Swift 6 size MS at 93 also by +1 km/h. 
The brake travel is short with moderate, to slightly hard pressure. The Swift 6, Maestro 2, and Mentor 6 are slightly lighter. And again, some pilots would appreciate that solid feel in their hands.  The agility is quite ok on the M7. Probably a bit less agile than the Mentor 6 XS tops at 90, but still quite good, close enough to the Swift 6 agility in thermals. In some small thermals, I was able to core very tightly without missing the core. 
If you want it more agile, try to pull the B3 at half pull inside a thermal, and you will experience a super agile B glider! :-) It's funny to try! 

My tests are not only about performance, so I will try to describe the feeling under it as much as I can and that could help you decide if you also cannot get one.

In strong cores the Mentor 7 has a nearly absent pitch behavior, the roll also is very dampened. It slides efficiently through the airmass calmly and the climbing ability is surely present but slow. 
I mean it climbs ok but needs time to reach the cloud base as the other gliders in the air.  In weak thermals, this insane stability erases the small information about that tiny lift, so it is very difficult to feel that tiny lift, and also the climb is there but needs time to get to higher altitudes. 
Some gliders could be described as having a good float ability in the rising airmass. The Mentor 7 size XS, that I flew has a moderate float ability if flown at 90 all up. 

The turning behavior inside any thermal allows the Mentor 7 to stay on rails. It never gets thrown outside the thermal, and with its brake authority, I could place it immediately whenever I wanted inside a core.

Gliding with my friend on his Swift 6,  ( I think your eyes are more open now? … :-)    Hmmm…Ok, So in gliding in the same airmass my friend pushed a bit on the bar to stay close to my trim speed on the Mentor 7 Light. The glide is close enough and I will update my B comparison as soon as possible for the little details if needed…
Trying again and again in many types of conditions, showed me that the Mentor 7 light has a very good glide efficiency that is close to the best ones in that category.

Pulling half the speed system showed me a glide improvement on the Mentor 7 light which is really interesting and will place it at the top of that category. At the full bar, the Mentor 7 Light is a fast high B with probably 2 km/h more speed than the Swift 6 with the same load. I think maybe I got a 16 km/h over the already fast trim speed.

Ears while pulling the B3 are really cool! They are very efficient! I could get down nicely on this configuration. Moderate 360s don’t deliver high G’s, and less than many B’s. 

Conclusion:
NOVA delivered a different Mentor.  It has a completely different feel, a different design, and a different approach! NOVA aficionados will give their own judgment after a test flight…
I only Wished it had more lift ability and a more nimble feel, but that’s me and my picky bad habits ;-), but for strong alpine conditions, the Mentor 7 Light will let you concentrate on the task, on the scenery, on your favorite snack, chocolate bar, while gliding through that abundant lift.
The combination of accessibility/performance ratio is really high on the Mentor 7 Light. 

UPDATE:
Today was a good day to try and fly the Mentor 7 Light, XS at 86 all up.
I changed my harness under the Mentor 7 XS to the Genie light 3 size M which gives slightly more roll and nicer weight shifting. My overall weight was 86.
I have flown on a generous day with some turbulence that my friends informed me later on landing… I thought it was really calm under the M7.

Flying the Mentor 7 light XS at 86 all up, gives even more comfort and still with a very coherent and taught feel. In turbulence, the glider stays well connected. I have flown many gliders, and I think this is not an evolution in feel, but a revolution since this high B glider is calmer than some EN-A gliders. Pilots coming from the low B category will immediately feel at home under the Mentor 7 Light which is targetted as an intermediate glider for pilots who already have flown lower-rated gliders, and like to move a high-performance glider.

In weak conditions, less than 0.5 m’s, the overall movements in pitch and roll are super dampened that I needed to concentrate more on the vario sound to core efficiently as the overall movements are nearly absent in those small conditions.
And of course, being at the middleweight does favor slightly the climbing ability and in a moderate 1m/s thermal, the Mentor 7 light flown at mid-weight will climb close enough to many high B’s. My comparison is updated for the little details.

Interview Michael Nesler

Hi,
In those difficult times, I'm trying to send glider designers some questions in order to give you a more comfortable way to spend the time at home. Here's is a very interesting interview with Michael Nesler.
I knew about Michael Nesler's designs since I began to learn paragliding. He is from the “golden era”
His exceptional profile!
https://profly.org/Nesler/?fbclid=IwAR2BWVXaBxlExeTXrozwoC
( Click personal)


Dear Michael,
At first, I hope that you and your family are doing ok! The conditions in Italy are critical, and hats off to the Italian doctors, nurses and everyone involved…God be with you all!
Thank you for taking the time to answer my questions.

Ziad: I have flown your designs recently. Let's take for example the Nyos RS EN-B.  It doesn’t have a shark nose, or the back positioning A’s, the lines are not that thin as some high B competitors, but it seems to glide as good as the best!  In your opinion for the moment, is positioning the A’s far back, for a high B is a must for selling? or there’s some benefit in that category in cutting through the airmass? Will this work for a B? Knowing that the latest Ozone R5 doesn’t seem to have the shark nose of the older models.

Michael: What ultimately determines the performance of a paraglider is very complex. Let me give you an example: If I have the Nyos RS made in China, it will fly like the one you've been flying. If I have it built in our factory in Croatia with the same files and materials, it will fly much better.
According to the experience of the last years, the dependency of performance is roughly distributed like this:
* 35% project
* 25% material
* 40% manufacturing quality (cutting, sewing, control)[/i]
Of course, the media and customers get off on technical, tangible details such as shark nose, A-loops, etc., but precision is much more important.
The fact that the Shark-Nose cost performance has meanwhile been accepted by other manufacturers. That's why they still install the rods crossed at the opening, but when you look at the profile shape without opening, there is little left of real Shark-nose.
In summary: If you could make any model you wanted with better materials, individual cuts, and very good sewers, it would be vastly superior to mass production. But no manufacturer can afford that.
The position of the A-Loops is not important for performance, only for safety and durability. And this is contrary to each other: Either more safety and shorter service life - or vice versa!



Ziad: I’m impressed! I never knew that it would differ that much! There are companies in Srilanka doing a clean job on paragliders. Do you still think that if it's done in Croatia or should I say in a more delicate and precise way it would fly better? How better please? What are those differences?

Michael: No, factories in Srilanka, China and other places are doing a clean job for economical serial production. But they are far away from the maximum possible.

Ziad: You said earlier that they can't afford that?  why? Can you comment, please?

Michael: Simple to calculate: Cutting 16 layers (8 gliders) on rotating knife cutter or high power laser needs nearly 8 hours = 1 hour/glider. If you make a single cut with high precision, you need also 8 hours = I glider!
A good sewer needs 30-40% more time to finish a perfect wing. So in the end, the glider will cost, also using the best material, quality control, individual trimming, ca. 60-80% more. Nobody will pay for this!


Ziad: You also said: On a competition glider, no one will use a shark nose if its cost performance! The Enzo 3 and B11 use it. What are your thoughts, please?

Michael: They are far away from real Sharknose: if you don't watch the crossed ends of the rod in the vent, but the real shape of the profile, you will see that there is nearly no shark-nose anymore! Only simulating a step on the vents you don't get a real shark-nose: te vent area is filled with a compressed air cushion!


Ziad: There are lots of nice ideas for designing paragliders. I always wondered if we put all them together in one glider, would that be beneficial? Some could be for marketing purposes, but some works quite well… I mean for all the classes, probably a shark nose, RAST, a 3D clean leading edge, and all the internal technologies, optimized unsheathed lines, etc, etc…  or there’s something that today's designers cannot overcome.

Michael: I am currently working on an EN-D two-liner, which we have both with and without a shark nose. In the lower speed range of the certification, the Sharknose doesn't make sense, it just causes disadvantages.
If I were given the job of building the perfect glider, I would:
- Take this material here: https://www.extremtextil.de/dyneema-composite-fabric-ct03e08-12g-qm.html (I've built a couple of base wings with this, brilliant!)
- Cut the glider individually by laser
- Glue all panels before sewing
- Accompany the sewing personally
- Use Vectran lines
The absurd thing is that such an existing model would fly better than a new, allegedly improved one of conventional design.


Ziad: Why Vectran lines?

Michael: Vectran has less elongation, is more stable during aging, am stronger. It would be perfect as main lines, also with cover. But till today nobody is producing Vectran baselines for Paragliders (with colors, coating/cover). But they are used for many years in high-performance skydiving canopies.

Ziad: What are your thoughts about a super designing tool? Will a futuristic superior software help in the design of our flying machines? Or are we still limited by the materials?

Michael: We have long been outside the reasonable tolerance with regard to production and material. It will hardly be possible to increase performance with conventional and inexpensive solutions.

Ziad: I was always fascinated by the internal structure of a glider. For example, the UP Escape had some cross reinforcements that were never been seen lately?  Is it right to believe that internal structure is the main key to performance and safety?  Are we still far in this field?

Michael: I know the Escape very well, I made it. But this construction has one main disadvantage: too much waste, too expensive!
The inner life serves only one purpose: Less lines! There is one clear limit: the strength required by the certification. Most high-performance gliders push this to the limit. So you couldn't have less lines. A highly complex inner life is interesting and light, but it is certainly not a parameter with which you can improve performance.
Unless you build gliders with over 100 cells, they would become too heavy without 4 or 5 cell spacing.

Ziad: What are the benefits of using very light construction of RAST on a 7 AR 2 liner glider? I think you surely thought of that!

Michael: I have been flying it for 3 months now and it feels like an EN-B paraglider to me. I fly it here in the Dolomites in conditions where others prefer to stay on the ground with the B-gliders, and I feel comfortable. What I miss is better take-off behavior in snow and tailwind and big ears.
But I have now found a solution for this, including certification without folding lines.


Ziad: What are your future projects? Any new harnesses? certification for the 2 liner?

Michael: I am working on a harness for pilots who like to fly very precisely with weight and want to be a perfect unit with their equipment.  This will be a niche product: Ultralight, high strength (with Kevlar fabric and Dyneema), with seat board and no cross bracing. So completely against the mainstream. This is not a Swing order, but a Profly project.
EN-D is in work and should be approved according to Corona.


Ziad: What do you think about seat and seat-less harnesses? Rear fairing or not?  Which do you think is more appropriate to your liking?

Michael: We have several harnesses here for testing our gliders. And have found that flight behavior, performance, and safety are more influenced by the different harnesses than by the trimming.
I am surprised that the manufacturers of harnesses do not even adhere to the requirements of the certification regarding the height of the main suspension. Most of the current harnesses have a much higher main suspension than the certification requires. In addition, the newer harnesses are being cross-braced more and more. This allows weaker pilots to fly with higher classified gliders, but it reduces performance significantly compared to flying a simpler glider with a good harness.
In all comparisons, I still find the old Woody Valley GTO-Xalps Race (2.2kg, with a board) the best for me.


Ziad: what if we were all flying the same model and there were no other models?

Michael: Then no one would be able to blame the material for bad flights, no one would be able to boast of being an unpaid brand ambassador, and no one would be the hero anymore for flying such a great, dangerous glider.
Ziad: Would this be less fun then?

Michael: Let's face it: the whole discussion about performance is only needed by the manufacturers, the salespeople, and the media. After all, what else would they be able to captivate us, pilots, with?
I still like to build high-performance machines on commission, but nobody really needs them.
Most pilots would be better advised to work on their technique, perception, and psyche instead of constantly stunning themselves with new material.


Ziad: You mean like one design glider for "Olympic games"? But that will also be branded somehow...
Michael: Here we have been shortsighted! If we got a one-design class for competition (ok, different brand, but very strict parameters like in sailing or formula one) we would be since many years in the Olympics! The same model means, that the results come from the pilots and not form the glider (and the money to buy always the best wing)


Ziad: A message for the pilots staying at home?

Michael: This is a good time to start thinking about flying:
* Why am I flying?
* What's in it for me?
* What would give me more performance?
* What are my goals and wishes when I fly?
It is best to write (on real paper!) because this keeps all-important channels of perception involved (sight, hearing, touch).

Thank you very much for your time!

Best regards,
Ziad



PS: Every designer has his own perception and futuristic ideas. The above interview was made to show a different and interesting point of view.
IMHO, the best glider you seek is the one that makes you feel good, and that special 'you' is a very personal matter Smile
Stay safe!
Ziad

Swing Agera RS SM




The Agera is Swing’s new C glider with RAST. 
Taking off is quite easy, and i didn’t find any particular problem in inflation in nil wind. In strong windy take off, the Agera RS also inflates quite nice and stays easily above the pilots head.

I flew the Agera RS from 96 all up on the SM size (88-100) 
The brakes have medium to light pressure and the Agera turns with very little action on the brakes. The turning radius inside weak and strong thermals are fairly agile. It turns inside a core but stops in the middle and needs to re-power it by releasing the inside brake in order to give it more energy, then lower it again smoothly inside a small core in order to get a tight radius. The Agera RS tends to stop inside one complete tight turn. But i can say that it has a fair agility and needs to get used to.    

Inside a tight core, i tried to keep my inside brake low and tried to lower it slightly more to keep it on track like i tested the other C’s like the A5, Alpina 3, Volt 3. In that matter, the Agera RS doesn’t really accept lowering the brakes near the hips to crank it…It will go into a mild spin. Nothing alarming here…It’s easy to sense for a C pilot, and when releasing the brakes a bit, the glider flies smoothly. So Swing was very keen to announce that this glider is intended for high end C pilots in terms of piloting level. So i felt that the best way to turn it tight, when the glider stops inside a turn, is to give it more energy by releasing the brakes a bit and re-apply it smoothly with weight-shift. 

I made some glide comparisons with an Artik 5 which is a very good glider in that matter, and found out many times that the Agera RS has IMHO, the highest glide on a C ever seen. Indeed, the glide is simply amazing, with a trim speed that’s slightly faster than an Artik 5 fully loaded. I even tried some glides with an LM6 size SM and found out that the Agera RS plays in that class in terms of gliding in moving air. I also felt that when there’s turbulence and difficult windy conditions, that the Agera RS performs at it’s best. So when i let it fly ! the glide angle is superb for a C certified glider. I forgot to say that the Agera RS doesn’t seem to have a shark nose, and the leading edge looks similar to the Nyos RS, with more cells of course, and smaller openings.

I also tested the climb rate in weak stuff. With a Delta 3 SM loaded art 91, and with an LM6 SM loaded at 95. In weak thermals, the Agera RS didn’t feel like a floater. It climbs ok thought, but those tiny bits of lift (-0.5 m/s) , were better smelled by the Delta 3, Artik 5, LM6. So i was hovering a bit more to find a slight steadier core to climb. In stronger cores, the Agera RS climbs really well. It has that power to dig through and climb. 

The speed system has moderate pressure and the top speed seems 12 km/h over trim. Racing a bit with half to full bar, the pressure on the C’s was very ,very light…And considering controlling it in turbulent air like a 2 liner is quite different. Flying the Zeno, a two liner for example, has immediate swift contact via pulling the rear riser, even in turbulent air.  But of course, the Agera RS is not a two liner ! 
It needs a longer input and a  bit more refined C pulling as the Agera RS will be slightly talkative at bar in turbulent air. It surely needs some hours to get use to it, especially to keep the glider from shooting forward in strong air if the pilot is only using the C risers control when going from half to full speed in turbulent air. 


Conclusion: For me the Agera RS properly loaded from 96 to 100 could be very efficient in Alpine racing. The Agera RS glides very well, and convert the bumps in an efficient way. It’s also a comfortable glider to fly in active air. I mean the roll movements are dampened, and ressembles the Volt 3 ones. The glider pitch forward a bit in turbulent air especially at bar but nothing difficult for a regular C pilot. The pilot must be smooth on the handling and refine his feeling on the brake pressure when the cores are very small and when very tight turns are needed. Otherwise European conditions are far different from ours, with larger radius thermals ! 
Probably the RAST system could have gave me that comfort overall feel, like on the Nyos RS, but surely more pronounced on the Agera, but still smooth feedback from the surrounding air is well provided.

UPDATE:
Swing Agera RS (revised version)  Size S.


After the issue of some lines on the Agera RS, Swing revised their C glider. This is the S size of the Agera RS flown at 88 all up.
The handling has indeed improved a bit. Now pushing the brakes into the core doesn’t spin easily the Agera RS, but funnily the tips tends to go back without any consequences. The agility is quite similar to the one i tested before, and inside the core i had to release the brake and pull it again to be able to tight turn some narrow cores. Otherwise it will flatten and gets out of the turn. 
The glide ratio is the same and its pretty nice.  Landing on a tight spot is a bit difficult and needs a good pilot probably because of the flat polar of the glider. 
The Agera RS doesn’t like to be slowed much, so care must be taken on super small landing fields.


This is only my opinion. Make your own !

SWING Nyos RS




Swing Nyos RS 
The last Swing glider i flew with the RAST system was the Arcus RS, and here’s the new high-end B from the same manufacturer, the Nyos RS in size S (75-95) flown at 93.5 all up with an X-rated 6 harness.
The Nyos RS construction holds a normal nose. The lower lines are sheathed with the higher ones unsheathed. The lines are slightly thicker than the competitors in the B category.   
Launching is quite easy in nil wind, and even in strong breeze. The Nyos inflates quite smoothly and evenly.
First turn, i could feel the moderate to short response on the brakes, with quite a nice agility in thermals ! The Nyos RS turns quite flat with moderate pressure on the brakes and could be described as quite agile! It doesn’t handle like an acro wing for sure and it’s not suppose to, but for a handling seeker like me, it’s very satisfying ! Thermals can be cored very tight, even the turbulent ones. 
The handling alone doesn’t really matter sometimes if the glider above the pilot is jumping around all the time. Underneath the Nyos RS, the movements in turbulent air can be described as “computerized self controlled” , as the Nyos RS feels very compact and super smooth to fly !
I flew this glider in some turbulent air, and got myself into a sunny lee side of a cliff, when the wind was blowing around 20 km/h from the other side. Usually the experience is not really joyful…but it was quite soft on the Nyos RS ! I got a bullet thermal that got me into higher layer, and kept my flight going on further.
I have been flying this path for a very long time, and underneath plenty of gliders. The Nyos RS was the coolest, most reassuring, comfortable glider ever to be flown among B’s ! 
The experience flying the Nyos RS is exceptional when it comes to comfort ! Even compared to some low B’s !
 Having said that, the Nyos RS could not be considered as a dull glider at all. 
It will inform the pilot about all the movement of the air around, but with such rare serenity and homogeneity and an efficient leading edge that surfs the airmass moving constantly forward in a super smooth way ! Incredible ! All that, led me to say, that the Nyos RS is indeed “The Rolls Royce of the sky”  ! 
Even in turbulent air, there not pitch back ! The Nyos RS just simply move forward quietly with that amazing solidity and super cohesive structure ! Some B gliders will have sharp movements, or a bit of yaw, some pitch…But not the Nyos RS. It just inform the pilot and filters wisely only the excess of turbulence !
Gliding with top high B gliders in moving air, i could notice that the Nyos RS is very competitive, and i could put the gliding efficiency among today’s top four, high-end B gliders.  
The interesting part of the glide in turbulent shaky air, was the easiness of the C risers control.  Using the bar in total confidence with the C riser control will deliver a quite efficient glide and they are super easy to use with moderate and progressive pressure. If only a thinner line version would be feasible, it could perhaps squeeze up even more overall performance to dominate the category.  
Climbing in weak and strong could place also the Nyos RS among the top 5 gliders in the high B category.  
Ears are stable, efficient, and reopen without pilot input. 
The pluses:  The ratio of usability ! I mean exceptional comfort and homogeneity with smooth information coming through! 

Conclusion: The Nyos has a normal nose, normal width lines, yet it glides beautifully and efficiently into wind. As for the flight characteristics and compact structure, I can totally confirm that the Nyos RS has somehow a different feel from many B’s i have tested. It has a very taught, super homogenous structure, with precise and direct brake response.  The comfort flying the Nyos RS is very high. Pilots flying in strong air and alpine conditions wishing for a solid, well mannered companion, should strongly consider flying the Nyos RS as a good option.  
I’m not an engineer to talk about RAST and the benefits that comes along…but it seems what i have experienced flying the Nyos RS couldn’t be understood otherwise. 



This is only my opinion. Make your own !

ICARO Buteo



This paragraph will be published before every written glider review.
-Gliders sizes may differ a lot ! The smaller ones react very differently sometimes with less gliding power. One review for a size doesn’t include all…
-Personally i like to fly gliders at + 70..80 % of their weight range…Sometimes at top weight…As i believe in (Being a pilot underneath a glider, is much better than being a passenger)
when you load your glider at it’s perfect load, it would be much more efficient in all conditions, and you will have a better feel through the brakes with a more obedient glider in rough air.
-Pilots (especially loyal to a brand…) who were waiting a lot for a certain new model, will always have bitter reactions if they read any review that doesn’t meet their expectations and dreams. (Logical ! )
Sometimes they understand a normal rated review as a superb review !
-Any good pilot who has flown many gliders can write fruitful invaluable tests, but he must omit any ego related and attachement for any brand whatsoever. (Very hard for some…but doable )
-Flying a glider alone in any site, in weak conditions (-0.3 m/s) , won’t help notice good float-ability. Flying in company to a (pilot/wing) combination that you know well will help evaluate your findings.
-Higher efficiency in active air, for a future purchase is the right direction to look for better overall performance (if needed). Not gliding in calm air ! Otherwise, a balanced glider for your abilities, with beautiful swift and agile handling that keeps you smiling, is always much better !
-For a respective category, any glider in today’s technology can get you very far, with incredible XC achievements.
-In one solid category, ex:(high B), there’s of course little differences in glide. A good pilot can fill those performance gap !
-Pilots have different taste and requirements. I will always try comparing a glider to another. ex: Glider X has more brake pressure than Y…Or Glider X is more agile than Glider Y… Etc…
-Finally, it’s YOU the pilot who will make the difference! By choosing the agility you want, the category…The glider level… NO review should alter your judgment ! Test fly…Test fly… 
My small reviews are ‘only ’to help you test fly your favorite group of gliders.


ICARO Buteo S
The last flown Icaro glider, was the Gravis. It was a mid B glider with very good climbing ability and nice glide for the Mid B category.
Now the Buteo is a new ICARO design with 82 cells and two lines per side ! It’s indeed a complex structure intended for high EN-B performance flying.
Launching the Buteo S at 96 all up need a steady, but light push on the A’s. It needs a little more implication than a Mentor 5 S and slightly less than a Carrera plus S.
Flying the Buteo S at 96 seems nice for the S size. The trim speed is fast. Similar to an Iota 2 with same loadings. The brake travel has a medium length to react. The Buteo turns fairly well, but i can’t say it’s an agile glider like the Gravis or the Mentor 5 S , Chili 4 XS is the high B’s. The turning ability is moderate but a longer pull can place the glider well inside a thermal. The pressure on the brakes are also moderate, and lighter than a Mentor 5 S and harder than a Rush 4 MS .
Climbing in very weak thermals (less than 0.3m/s) , i was focusing hard to stay up. A Chili 4 S similarly loaded was slightly floating better. When the thermals are more steady and above 1 m/s ,the Buteo S climbs well. I was climbing with friends on their Cayenne 5 S and Delta 3 ML, and i felt that the Buteo in well built thermals (+1…2 m/s) does in fact stay very close in climbing power.
The Buteo have a slight pitch back or slightly slows down upon entering thermals. Nothing much, but feel-able. It ressembles the Nyos 1, M size in that matter.

Now the interesting part is the glide. I flew the Buteo for many days with a Chili 4 S size, a Cayenne 5 S, and a Delta 3 ML ! I can confirm that the glide ratio of the Buteo is on the very top of the B category, and it’s super close to the C class in gliding at trim and at full speed in calm air. The Delta 3 ML has a 3 km/h more speed. At the end of a 7-8 km glide, i was always slightly losing some 5m…sometimes 10m ! which is insignificant. In a more challenging, turbulent and bumpy environment, the Delta 3 and Cayenne 5 S (C class) will be slightly more efficient in surfing upward the air mass.
The Buteo comfort is quite ok for the high B category. It could be similar to the Chili 4, or slightly more demanding in strong turbulence. Of course, it’s less demanding than a Carrera plus M !
The movements in turbulent air are filtered under the Buteo S size at 96..97 all up. The reactions underneath in turbulence are slightly slower and mellower than the Chili 4 XS.
Big ears are stable, and reopen without pilot assistance.
Conclusion: It’s obvious that the Buteo S at 97 has a very good glide angle. I think loading it at top in alpine conditions will be quite beneficial for cruising efficiently in XC mode. 
An interesting glider for a specific generation of pilots

This is only my opinion. Make your own !

EN-B comparison UPDATE (Ozone Rush 5 and U-Turn Cross rock)



Info’s: In this race for performance, the recent 2015/2016 gliders are having very thin line set up. Whether on a B, C, or D glider, I have found that those gliders from different manufacturer does in fact change slightly (Still with a large safety margin, within the permitted stretch tolerance with no required adjustment) …They just settle to a certain configuration...Some after 20 hours, and some after 100 hours…But they do change slightly…That’s why flying them again and again will in fact change their characteristic slightly, and this will show on marginal conditions, especially in weak conditions, or in strong head wind conditions.

(THIS COMPARISON HAS BEEN UPDATED ALSO FOR SOME OLDER GLIDERS AFTER MORE AND MORE FLIGHTS UNDER DIFFERENT CONDITIONS)

The best I can do....

C & D gliders:

This grade is to say how busy a glider is, in strong conditions, or the one that’s more difficult to manage, comparing to the B category.



Since this is a very delicate comparison, i must point out that the glider that has quicker authority on the brakes like the Triton 2 will enable a good pilot to keep it swiftly overhead. Some doesn’t have that quick response and in strong conditions they won’t keep the pilot as busy, but he will be the ‘passenger’ for a short lapse of time …

The grade doesn’t indicate the one that recovers easier or harder!!Only that keep you busier! Most will have easier recovery than the higher graded!

The Leaf is impressively comfortable and agile. I was hoping for better glide but it's super cool !

The Epsilon 8 has good performance for a low B. It's comfortable with nice handling.

The U-Cruise has a high degree of comfort. The performance is really good, and a high trim speed.Agile, feels like a solid tough structure!

The Nevada 2 has less brake travel than the 1, the performance is nice and the climb is moderate to fair.

The Eden 5 has less top speed of 3-4 km than the others.

The Hook 3 is very comfortable to fly with a very interesting glide angle. The climb in smooth conditions is fair.

The Mentor 3 is much easier than the Mentor 2, and its efficiency is in those turbulent glides where it will have less pitch movements and little better glide.

The Mentor 4 has better glide than the Mentor 3 but with lesser climb “only” in weak conditions.

The Ikuma is a comfortable glider with nice handling. The overall performance is is in the mid of the High B category.

The Iota has a very good glide similar to the Mentor 4, It has a nice climb similar to the Mentor “3”.

The Chili 3 S “still” has the best climb rate and a very nice handling in homogenous conditions. But with a very long brake travel.

The Advance E7 26 is the most confidence inspiring rock solid glider of the cat. It reminded me of the low B cat in comfort.

The BGD Base is a confidence inspiring, solid glider. The climb and handling are very good.

The Atis 4 has a bit roll movement and need some active piloting in the high end B’s.

It has a fast trim speed, much like the M3 and Chili 3. Long brake travel are needed to let the glider respond in turbulent conditions.

The UP Kantega XC2 S is a very nice wing to fly .It has nice handling and also superb climb overall being also very accessible.

The Swing M7 S is a delight to fly. It dives a bit into turns. It is fast enough for a B, and has enough performance. Not really a floater but a nice glider overall.

The Rush 4 has a very good glide . It is an overall good, very solid B glider, but its trim speed is around 38 km/h and especially the top speed which is low for the cat around 51 km/h .

The fastest are Mentor 3, XC3, Mistral 7…But it is around 55-km/h max.

The AD rise 2 M has the BEST ratio Performance/Comfort in flight!

The Tequila 4 SM is like a precious gem! Combining agility/performance/accessibility!

The Infinity 4 has a very light and nice turning behavior! It has a low trim speed , and the climb rate even loaded is outstanding!

The Comet 2 S give a nice feeling under it. It has a very nice handling.

The Windtech Bali has a respected glide angle. It needs slightly active piloting in big air.

The Atlas S has everything to make its pilot very happy, with a good feeling of passive safety. The X-Alps version of the Atlas has more performance overall, especially in climb.

The Arriba is slightly more dynamic than the Tequila 4 and a pleasurable glider to fly.

The Rook 2 is a well-balanced high performance B glider, with nice handling and efficiency.

The Nyos is very comfortable, made for strong conditions. The gliding performance is very good !

The Eden 6 26 is a very balanced all round B glider toward performance flying, and respecting a pleasant pleasurable feel!

The Buzz Z5 has an upgrade over the Z4 in performance while retaining the comfort. The brake pressure and feel in thermals is really nice!

The Cross country is a light glider with pleasurable handling, and comfortable behavior.

The UP Kibo is an accessible B glider with a comfortable ride.

The Sky Apollo is a pleasure to fly.

The Gin Sprint 3 M performance /comfort ratio is very good.

The Chili 4 has lots of performance. It’s an excellent B glider with moderate aspect ratio.

The Mentor 5 S has the top overall performance in the B segment. Close top the Chili 4. Its relatively an easy B glider..Easier than the M4, and could be similar to the M3 in pilot level.

The Phantom has a very high performance for a very low aspect ratio. If the price would be +1.50 % from the others then it’s highly justified…

 The Explorer with it’s 6.1 AR, is a light, soft, easy to use, and great companion for XC use 
The UP Summit XC4 with its B rating, is IMHO a mild (C) glider, like the Carrera series. The overall performance and handling is really on top ! 
The Iota 2 has a very accessible and easy to use speed system. A very nice XC machine !
The Rise 3 S flown at top is a serious contender for the new 2017 high B's.
The Nyos -RS has the best ratio of : comfort / performance in the high B segment ! A very good XC machine for strong air.
The Ozone Rush 5 has the best ratio of comfort/performance for a high B ! 
The Cross rock is a very interesting light B glider, with very accessible use and very good performance.


Conclusion: The Carrera plus has now two direct competitors, the M5 and the Chili 4 in pure gliding power and climb!

The M5 and the Chili 4 have a low aspect ratio, but totally competitive with the best high aspect ratio B gliders.

The Carrera plus climb is even better than the original version only in weak and moderate conditions. The more the headwind, the original version cut forward more efficiently.

The Phantom is a cool glider for long XC’s in the Alps! Its overall performance will get you anywhere in a cool manner. Just fly it at +75% of its weight range for efficiency.

The AD Rise 2 is very comfortable to fly with a superb glide for the high B category.
The AD Rise 3 has the top performance in 2017, with a good efficiency for a B.
The Iota 2 -25 flown at top, is a super efficient and easy gliding machine that can get great results for the years to come.

The Rush 4 like the Swift 4 has nearly the glide of the Mentor 3 but with lesser speed. It's an overall efficient glider in difficult conditions where it could cut through turbulence and have a very solid and compact feel coupled with a direct handling.

The Mentor 4 has now the best glide in difficult conditions among the similar aspect ratio B’s very close to the Iota and the Rook 2. The climb in very weak conditions still favors the Mentor 3 S similarly loaded.

The Atlas X-Alps is an easy “all rounder” with very good performance especially in weak climbs and low saves.



I’m certain that a good pilot can break an XC record with ANY of those superb B gliders from above!

Please pick the one that will make you feel happy under it ….The rest is up to you!

Cheers,


Ziad
