SKYWALK Chili 4 S and XS



SKYWALK Chili 4   (The powerful package) 
Yes …..They were a bit late to arrive !
 Two SKYWALK gliders with an EN-B certification. One is the S size (85-105) and the other the XS size (75-95)  Both are the new CHILI 4 as a high-end B glider which will replace the floatable Chili 3 !
Lets see what SKYWALK did with the Chili 4 who took quite a while in development. I was very curious to see what are the benefits on the B category and i was keen to see if SKYWALK did manage to keep the excellent climb of the Chili 3.
Looking closely at the glider showed a trendy approach with a shark nose, a  pure 3 line configuration, with very small minimalistic and finely tuned line width ! Some lower lines are sheathed and the higher ones are unsheathed. Putting all the lines on one hand, feels indeed very small, it looks smaller than the Mentor 4 ones.
Launching the Chili 4 XS at 92 all up is an easy task with no delay or shooting forward. A simple glider to inflate.
In the air…and already smiling… The brake pressure is exactly to my liking. Not as hard as the Mentor 4 one, nor as soft as the Rush 4 one. It has a moderate pressure with immediate short response. I could put the glider exactly where i wanted with a linear travel !  It isn’t as agile as the Tequila 4, but close enough! I can say that the Tequila has a playful handling, as it dives on quite playfully when you pull hard. 
The Chili 4 has a Joyful efficient handling. It doesn’t dive but has a “flat” corkscrew ability  :-)  !
The pilot can steer it with a much more flat performance turn ! At my all up weight, i was able to core the inside of any thermal. The agility ressembles the Rush 4 or the Swift 4 which are excellent handling gliders.  
With it’s short, linear, responsive and agile character, SKYWALK managed to fix the old Chili 3 handling problem for good !
I’m going to write now a bit about the brand new S size (80-105) flown at 100 all up versus the Mentor 4 S (80-100) flown at 95 all up. (This Mentor 4 S has only around 50 hours) And still in a very good shape and wasn’t flown beside testing and comparing in XC conditions.  Both sizes are flown 5 kg less than the top certified weight.
Gliding along the Chili 4 S with the Mentor 4 S showed a similar trim speed. Probably the Chili 4 S has a 0.25 km/h faster. Comparing the trim speed of the Chili 4 S at 100 all up and a Cayenne 5 S at 100 all up will give the Cayenne 5 a little more speed at trim . (Just for infos only) 
The top speed of both the Mentor 4 S and the Chili 4 S loaded as mentioned above has the same top speed with a slight 1 km/h more for the Chili 4 S.
What are you waiting for ?  ;-)  The glide ? .. or the climb rate ?  :-)   Lets see…
The climb rate in weak and difficult conditions gave me the impression that the CHILI 3 DNA is inserted deeply into the CHILI 4 ! 
But i think it’s much, much better…The Chili 3 was pitching back a bit before entering. The CHILI 4 has a super stable pitch entry ! I was flying for the last months the Zeno, and when the Chili 4 arrived, to be honest i was worried that i have to loose some flying days testing it…as i thought it will have this B feeling in thermal searching and performance feel  !
  I was wrong! The ability of the CHILI 4 to (slide, sniff, surf) the airmass is amazing, just like flying a higher rated glider. When all is calm above your head, you could hear the vario…Bip, bip, bip… It gives the impression to grab every bubble without the leading edge pitch and movements.
It doesn’t attack and search forward, but it climbs slowly and peacefully.  
Flew with my Mentor 4 S near the Chili 4 S, and i felt this edge in float ability as if my friend was flying his Cayenne 5 S ! Each time the thermals weakens the CHILI 4 floats better.
For sure it’s an efficient climber and here again SKYWALK has managed to keep the excellent climb of the Chili 3. 

The glide in calm air at trim and accelerated at full speed is very ,very, close to the Mentor 4 …but… 
In all the testing I have done before on the Mentor 4 and other gliders, I was always certain that if any glider could beat the Mentor 4 in glide it would be pretty awesome! 
especially in moving air !  
For example, I was pretty close to the Cayenne 5 S which eventually had the edge in overall conditions. 
Lots of pilots nowadays still ask about the glide in moving conditions… Well IMHO, it’s the BEST way to see the ability of gliders to surf the airmass efficiently…and it’s not done on a single glide where one can get a lift and other will loose it, it’s done on frequent glides, felt and seen, frequently on tip to tip glide comparisons. 
Doing those glides against the CHILI 4 S was obvious to the eye that the edge was now on the CHILI 4 side !!! 
In overall conditions, the efficiency of the CHILI 4 was tested, felt, and validated, to let me conclude that the CHILI 4 with it’s narrow edge is now the benchmark for the high-end B gliders. 
The problem for SKYWALK now is to create a more competitive Cayenne ! 
Flying in some moderate turbulence, the tips flutters a bit without any consequences. The CHILI 4 moves in turbulent air like any high-B glider.It’s not a super comfortable glider nor a difficult one to manage. It ressembles the Iota, Mentor 4 ability to control. 
Big ears are stable with and without accelerator. They open immediately without touching the brakes. 
If you pull two lines on each side, for much bigger ears, it will be un-stable (a bit). I must find something…  :-) 

Pulling one riser and holding it, doesn’t get a high sink rate and it requires a good weight shift and a little brake control to keep it straight. But so easy to handle for a high B.
Induced frontals are hard to pull in. It’s like the feeling of a two liner. Heavy pull is needed to collapse it. The reopening is average to good.
At full speed, the Chili 4 has around 13-14 km/h over trim and the leading edge still feels solid as pulling the riser doesn’t quickly collapse it.
360’s are efficient and the glider stays quite some turns to exit, so braking a bit the opposite side helps a lot.
Conclusion: What can i do when i feel satisfied with a tested glider beside a large smile ? I’ll happily write about it for you to experience my findings ! 
The CHILI 4 with it’s technical line configuration, need a good B pilot to master it efficiently, like any high end B glider and a careful approach to prepare in bad launching areas, with stones and roots. I found it best to fly the S at 101-103 all up and the XS at 91- 93 all up with no worry about the climb in weak.
Apart from that, the CHILI 4 gave me the sensation of a pleasurable flying machine with nothing but ’top’ overall performance, efficient and agile handling, amazing climb and gliding performance!
All that with a 5.65 AR (4.2 AR Projected) !   A very powerful package ! 
I’m very sure that some serious manufacturers are also aiming for excellence. For now the CHILI 4 has strongly earned its place among the best. Lets see what the future brings.
Beside doing competitions with speed tasks, I always wonder why we always look for higher aspect ratio gliders when a low AR good B can offer us tremendous amount of performance, swift handling, good passive safety, pleasurable feel and a deep happy satisfaction !   
Happy landings  :-) !

Chosen gliders in their respective categories

Those gliders below will be kept for future comparison as i believe that in overall conditions they gave me the best balance between performance, efficiency, handling, climbing having the edge in their respective categories. 
It doesn't mean that they could suit every pilot need ! Every glider has it's own characteristics and every pilot has their own feel and requirement. You can find their characteristics in the B,C, comparison charts.
May everyone have safe and smiling flights  :-)  

EN-B with lower aspect ratio than 6 = NOVA Mentor 4 
EN-B with higher aspect ratio than 6 = GIN Carrera Plus 
EN-C high and low aspect ratio = SKYWALK Cayenne 5 
EN-D = OZONE Zeno

EN-B comparison UPDATE Inserting the U-Cruise, Nevada 2, Sup Leaf, Epsilon 8.

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)

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 hping for better glide but it's super cool !
The Epsilon 8 has good performance for a low B. It's comfortable with noce 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 perfpormance 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.

Conclusion: The Carrera has now two very serious competitors, the M4 and the Iota in pure gliding power. The Carrera still climbs better “in real conditions” than any B in this table.
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 AD Rise 2 is very comfortable to fly with a superb glide for the high B category.
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

OZONE ZENO MS 80-100




OZONE ZENO MS 80-100

The Zeno is the new 2 liner from OZONE.
OZONE wanted to introduce to the market a 2 liner design , which they claim it’s easier to fly than their Enzo 2 and close enough to their superb Mantra 6.
In fact i still have an LM6 in MS size. It suits my all up weight without ballast.
I have also a Peak 4 in size 23 (85-105) for my future comparisons which proved to be a very nice and gentle D glider for Xc and competition use.


The Zeno has 6 lines per side, and it’s a pure 2 liner. Of course all lines are unsheathed and have different width. It looks very optimized for performance. Such a wing deserves a more detailed description when testing it. Lets see…

Launching the Zeno is super easy for a 2 liner. Slightly easier to inflate than the Peak 4. In strong wind, it needs a dab on the brakes to control it overhead. The take off is immediate.
I did some 360’s and wing overs ,just to get it well tensioned in order to settle down to its designed configuration.
To my surprise, coming off the 360’s couldn’t be easier ! It seems that the Zeno dissipate it’s energy on the last turn. No surprises ! Clean exit.
Wing overs are super high and real fun to make.

I have flown for the past month, the easy King S with it’s lovely handling, the LM6 magical overall glider, the energetic Poison X-Alps XS with its sharp handling, and the relatively smooth, and agile Peak 4 23 for a 2 liner design, just to be able to quickly place the Zeno among those D’s in terms of feeling, responsiveness and brake precision inside rough or smooth thermals.
All testings were done on the same X-rated 6 harness with the same chest strap width for all.(±47 cm)

I flew the Zeno MS from 93 to 98 all up to find out finally that in XC mode, 93-95 is a very nice weight, and for competition, 97-98 all up could be quite ok for the whole solidity and compact feel of the design which will feel more taught overhead.
Here’s my small and humble opinion upon this glider.

At first, I don’t think that the overall comfort is similar to the M6 or the LM6 MS when flown in turbulent strong conditions. The Zeno needs more active piloting in turbulent cores. Taking into consideration that the way a 2 liner can be steered through turbulence differ a lot from 3 line gliders.
Applying brakes on pitches, doesn’t really work good on the Zeno as it could work slightly more on the Peak 4 which is a 2 liner also.
The Zeno needs a much more gentle approach. Letting the glider go in, with just a feel on the brakes is super efficient on the Zeno. Too much brakes in turbulent conditions will deform the profile and the energy stored in the Zeno will induce yaw movements.
In turbulent air, I found out also that the Zeno needs slightly more active piloting than the Peak 4 23 i have over here flown at 99 all up. 


In (moderate conditions), the Zeno has indeed the comfort of the LM6 or the Peak 4. It feels like a taught compact structure, with a leading edge so stable without any pitch. The maneuverability is really nice for this 2 liner in those moderate conditions. But in rough air it gave me a much more active workout ! Nothing difficult for a (regular) D pilot to master.

For example a pilot coming from after a good flying season on an IP6 in different conditions will be welcomed aboard the Zeno.
The Zeno pitch behavior is toward a neutral feel in moderate weak thermals, but surely a more pronounced one in strong cores with a pull inside the thermals.

The pressure on the brakes of the Zeno are slightly lighter than the LM6, but still more pressure feel on the brakes than the Peak 4 23 loaded at 99 all up.
The turning ability of the Zeno at 95 and at 98 all up felt the same as the M6 (Only in moderate conditions) .
In turbulent cores, and even if loaded at 98, the Zeno will have slight less authority on the brakes as the M6, LM6 have in those conditions.

The LM6 is more agile and can core more tightly some thermals in overall conditions.

The climb rate of the Zeno is impressive in surges. When everything is homogenous strong or weak, it climbs as the Peak 4, but when you hit the core the Zeno springs up faster !

Doing some glides near a Peak 4 23 loaded at 99 all up. The Zeno MS at 95 all up showed me that the Peak 4 23 has a slight faster trim speed. Of course no one is buying those two gliders to fly them at trim speed for sure !
It’s just for your information ! And the glide efficiency at trim is slightly on the Zeno side. 
Now at first bar, the matter of glide became more serious on the Zeno especially into wind transitions in active air ! For sure we are in a different world …At second bar, the speed is impressive with a superior glide angle. The speed over trim loaded at 95 all up, is around + 22 km/h taken at 800 ASL.
The speed bar is delicate to use in turbulent conditions. Especially the top speed ! It takes time to adapt to it …
This is the fastest D certified glider i have ever flown.

The use of the bar on the Peak 4 23 is easier and as the pitch control.
Flying in smooth air won’t show you any differences when comparing gliders. Or even in head wind smooth air like soaring high cliffs for example. Many good pilots already know that.
The differences are very little and sometimes useless.
It’s in active air where a special glider can actually shine. It’s no secret why the Enzo 2’s are winning competitions…

The ability for the Zeno to surf the (active air) is really impressive ! It’s like it doesn’t want to get down. Comparing it with other gliders in those conditions, will give the Zeno this slight cruising efficiency. It just goes on and on on glides getting those tiny lifts on the way…Advanced pilots will understand what i mean.
The constant vario sound seems endless with those glides. This is for sure a very efficient glider in active air (for the keen D pilots)

That doesn’t mean that the Peak 4 23 is far behind. It is still a beautiful, easy 2 liner with nice performance ! But the Zeno will actually have the upper hand in long glides especially on bar with a slightly higher piloting level at speed for the Zeno !

Big ears with the outside A’s are stable if moderately pulled. With bar -2.5 could be reached…
Big ears with outside B’s are doable, more stable for sure and reopen quicker. The second option could be better if you don’t want knots on the extremities like on the M6 when ears are induced for a long time.


Conclusion: The Zeno has for sure the highest-end gliding performance (especially on bar), among all present D’s. That’s a fact.
Another fact is that in my personal view, it needs a “good D pilot” to master it efficiently in all conditions. For competition use, that’s some winning tool !
For XC, fun, safety, and multi-use, the LM6 still works magic ! ;-)
So, if you want to break records, win competitions, want to have the best glide angle on a (D glider) for the moment, and above all, you have the skills to master the Zeno, then close your eyes, take a deep breath, release the OOOMMMMM sound, then quickly go order one :-)
But it seems many of you already did  :-)

Cheers,
Ziad

ADVANCE EPSILON 8



ADVANCE Epsilon 8

As always, opening an ADVANCE wing is a nice experience since the quality of construction and materials are really nice .

The Epsilon 8 is ADVANCE low B glider. All lines are sheathed with strong line construction ! 
I’ve seen many gliders and that low B seems having an indestructible construction. It is obvious that ADVANCE wanted a glider that will last for a long time without even thinking going out of trim ! It’s a surely well built glider !

Launching the Epsilon 8 is super easy and a non event …No shooting forward for sure, no hang back…It just wait above the pilots head.

I flew the Epsilon 8 from 90 to 95. This handling on this glider is fine tuned for a wide variety of tastes ! You can turn it pulling 5 cm and it turns smoothly and you can turn it with 30 cm pull with the same smooth dynamism ! Excellent ! 
The pressure on the brakes are moderate, much like the Ion 4 ones. The overall agility for a low B is nice and well balanced !
Low B pilots can easily fly it, and a more advanced pilot can place it with little input in thermals. It has a surprisingly precise brake response. 
The overall movements in roll and pitch in strong turbulent cores (+7m/s) are super smooth and easy to understand with a glider that is smiling at you like a nice polite butler ! The Epsilon 8 doesn’t have a pitch back or forward before entering thermals .It has a very well balanced behavior. Newbies will adore !

The climb rate in weak conditions is efficient. The information is very smoothly given by the brakes and slightly by the risers. 
Going on a glide on the Epsilon 8 at trim and at full bar puts it among the top 5 of the low B gliders. Very easy to keep the bar fully accelerated.
Ears are super stable, easy, and reopen quickly. Landing the Epsilon 8 is a non event with a good flair. 

Conclusion: The Epsilon 8 has everything a low B pilot wishes. From a nice handling to a comfortable ride in turbulence and a good glide angle to begin cross country safely. It’s strong construction will ensure a long use.

GRADIENT NEVADA 2 S



Gradient Nevada 2 S  (70-90) 

The Nevada 2 is the new high end B glider from Gradient. 
2 lines per side on the A’s and three row of lines with similar configuration as the Aspen 4.

I flew the S size from 85 to 90 in different conditions from weak to strong.
Launching the Nevada 2 is easy for a high B glider. 
After some flights i found the best weight under it in overall conditions is around 88 all up.

The roll movements are present on the Nevada 2 S in turbulent conditions, slightly more than the Rush 4. 
In strong turbulent cores, a keen high B pilot could easily manage it.The improvement in brake travel is now enhanced over its predecessor the Nevada 1 with a relatively moderate to short brake travel, a soft pressure (like the Rush4) and a nice agility in turns. 
Before entering thermals, with no brakes applied, the Nevada 2 S at 90 all up slows a bit ,pitch slightly back and then climb away.  
The climb in weak is still very good even loaded comparable with the BGD Base. 
The glide at trim and accelerated is good for the high B category ! It could be placed among the top five in terms of glide efficiency !
Big ears are stable and a good way to get down. 

Conclusion: The Nevada 2 S has everything to be quite competitive and pleasant to fly for a high B glider. It needs active piloting in turbulent conditions. The glide especially accelerated is very nice for the category.

ADVANCE Interview ( Valery Chapuis) 
1-Ziad: Can you tell us please about ADVANCE new products for 2017 ? 

- Valery Chapuis: BIBETA 6, SUCCESS 4, SIGMA 10, Companion SQR 220. Other products are not decided yet. 
Please have a look at our homepage. http://www.advance.ch/en/home/news-pages/success-4-safe-and-comfortable-no-compromise/ , we’ll publish soon a complete information. 



2- What can you tell the pilots about the new Sigma? What do they have to expect? 
- Valery Chapuis: middle C wing with a very high level of performance (more than our OMEGA 9 photos from the beginning of this year) with a vey predictable behavior. With all the existing technology. 

Any D glider for the future ? … 
- Valery Chapuis : Maybe a OMEGA 9 end of next year. We are making new 3 and 2 liners photos. 


3-Ziad: The Iota is a high B with a very high ratio of : top performance / comfortable behavior with a moderate aspect ratio ! Now it seems the Sigma 9 follow that same path . A concept for the middle C pilots as you mentioned. Could you please elaborate on this ? With an approximate idea for the aspect ratio ?  

-Valery Chapuis: The Sigma 10 will be a middle C wing, I mean a real C wing, not a low D, not a high B. A normal sport wing pilot can easily fly a Sigma 10, the wing is very intuitive and predictable. 

4-Ziad: What about handling versus the Sigma 9 ? 

Valery Chapuis: Still very responsive but a little bit less direct than the 9, we were not far from a freestyle behavior, depending on the pilot weight of course. 

5-Ziad: Will it have unsheathed lines like the Iota ? 
- Yes, like the Iota and like the Sigma 9 as it is a wing aimed for performance and cross country flights. 

6- Ziad: Also its nice to see 5 sizes ! Very interesting ! Can you please elaborate on that decision ?  
- Valery Chapuis: 5 sizes will give more choice to the pilots and more possibilities to find the right size. 

6-Ziad: What's a 3D panel shaping ? and what does it do ? 
Valery Chapuis: The 3D shapping helps the leading edge to be more resistant as it reduces the elasticity of the fabric, that gives a better behaviour to the wing. 

7- Ziad: Who are the people behind this design ? In R&D and testing? 

Valery Chapuis: It is as usual our complete R&D Team. Silas Bosco and Hannes Papesh remain the computer designers and the test pilots with Kare Eisenhut as responsible make the wing as we decided in the design manifest. 



8- Ziad:Will it be there an impress 3 replacement in the near future ? 

Valery Chapuis: Yes we discussed already about a Impress 4 but we dont have yet a timing. 

9- Ziad: What's the difference between the Beta 5 and 6 ? 

Valery Chapuis: The 6 benefits of all the technology and knowledge we could acquire during the past 4 years after we made the Beta 5. A complet product presentation will be published next week in our homepage, please have a look it is really interesting. 

10-Ziad: Anything you want to add? 

Valery Chapuis: I’d like to add a big hello to all the pilots and don’t forget that you are not alone in your life, your family is expecting that you go back home tonight, then fly safely and always land happy. 


Ziad: Thank you very much !

SKYWALK Poison X-Alps XS !



SKYWALK Poison X-Alps XS (65-90)
The Poison X-Alps is SKYWALK light EN-D wing. This glider is the fruit of the wing used in the last X-alps race, trimmed and tuned to meet the requirements of the D pilots.
The Poison X-alps is a 7 aspect ratio glider with three risers and a shark nose. A small piece of wood attached on the C riser, is connected to act also on the B riser for a possibility to control the glider pitch when accelerated. All lines are unsheathed.

Launching the 7 aspect ratio Poison is an easy task with the light cloth. Quickly overhead, a slight damp on the brakes to keep it overhead and the take off is immediate.
I must state that different sizes behaves very differently. For instance when the Ozone LM6 size S has a slight pitch forward, The LM6 size SM has a neutral pitch, The normal M6 size SM has a slight pitch back ! I was flying the Poison X-Alps size XS from 84 to 90 all up. The M size could have other feel under it ... i just have the XS size.

I found after some hours flying the XS size, that 5 kilos below top is optimum as the balance of climb and speed is great ! I didn’t notice an increase or decrease in trim speed flying it from 85 to 90...But the climb at 85 all up is superb !
Also flying it 5 kg below top, decreases slightly its dynamism and smoothen up the movements in active air. Much like the Cayenne 5. No need to fly it at top weight.
I flew that glider in some turbulent air alternating flights with the LM6 SM. The Poison X-alps has a more dynamic feel under it. The roll movements are more pronounced over the LM6 with a lovely slight pitch forward that pulls you into the thermal.

All that is coupled with a precise, linear, short, direct brake response which i adore on board this beautiful machine !
The Poison X-Alps feels more taught in the air than the LM6 ( it feels like a solid, dynamic, compact piece) The information given by the Poison X-alps XS is spectacular ! A good pilot will feel everything in the brakes and also in the harness with the possibility to place it exactly
where he wants inside any turbulent thermal ! It needs more piloting than the LM6 in turbulent air and feels slightly more dynamic.

The LM6 is for sure a superb machine. But if i’m going to explain the difference between them and especially in ‘feel’ without talking about performance yet, i would say that, If the LM6 SM loaded at top feels like a Porsche. The Poison X-Alps XS at 85, feel like a Porsche GT2. Everything is fine tuned for slightly more precision, slightly more dynamism, slightly more race feel, slightly more steering pleasure !

Going on some glide on the Poison X-Alps XS at 85 all up with an LM6 S at top weight and an LM6 SM also at top weight showed me that the Poison X-Alps XS has a +1 km/h faster trim speed. At top speed, the Poison X-Alps XS has +16 km/h over it’s trim taken at 800m ASL.
As for the glide angle at trim and accelerated i would say that they pretty close. My 'personal' feel is a slight efficiency in head wind glides for the Poison X-Alps especially above trim,+ 47 km/h.

The Poison X-Alps XS at 85 all up is a very good climber in weak conditions. And for sure when the thermal streghten, it will shoot upward without any delay ! Overall it’s an efficient climber.
The speed system has a moderate pressure .The glide is superb ! Bumps are felt when accelerating in turbulent air and the pitch is controlled by pulling on the C riser which is slightly on the heavy side and could control quite some moderate turbulence. But not as much as a 2 liner does. For example, the Peak 4 'B steering' is much softer and more efficient. But of course its a 2 liner ! I felt that controlling the pitch with the C riser on the Poison X-Alps has to be firm and at the same time sensitive and precise in order to keep the glider levelled above.
360’s are super easy and feels quite nice with a very clean exit. Big ears are stable and doable with at the external B riser kit.

Conclusion: Test flying the Poison X-alps XS for "my personal taste” was an exceptional experience for a D glider yet ! The handling and the way it turns, feels and cut through the air, is superb !
It’s a slightly dynamic and talkative wing for sure in turbulence, but very well pressurised and has a homogenous feel for a 7 AR, top performer D glider ! The brake authority and responsiveness is among it’s
strongest points !
I loved the way it pulls into the thermal ! It sniffs and go through with a positive vario.
The authority on the brakes, usability and feel are exceptional on this XS size ! I’m sure that many keen pilots wouldn’t be indifferent after a test flight !  :-)

U-Turn Blacklight 2 S




U-Turn Blacklight 2 S

4 years ago, i test flew the Blacklight 1. The strong point was the excellent climb rate even in super weak conditions. Glide was very good, into wind glide was moderate, and the Blacklight 1 kept its pilot quite busy in very strong conditions having an aspect ratio of 5.8 flat at the time !

U-turn offers the Blacklight 2 in late 2016, with a moderate aspect ratio of 5.6 flat.
The 11 lines per side are a bit thick and sheathed . The upper ones directly to the canopy are unsheathed .
3 lines per side with 3 thin up to date risers and 3.5 line configuration.

A nice shark nose construction with semi circular openings. A very nicely and tough looking construction on that glider !

I flew the S from 87 to 90 all up. The launch behavior is easy without any surges or hang back. The take off is immediate.

The brake travel and pressure are moderate to slightly firm resembling the Eden 6 one.
The maneuverability in coring thermals is really nice.The Blacklight 2 can be turned very narrow into the core. It doesn’t really dive into the turn if applied smoothly. The Blacklight 2 has a very well balanced and pleasurable handling. The same size on the Blacklight one has a lighter feel on the brakes, and slightly more dynamic in terms of turning ability and surely in turbulent conditions, where the Blacklight 2 is much more comfortable than its predecessor.
I felt that the shark nose on the Blacklight 2 is much more efficient than the BL 1 in biting forward the thermals. The Blacklight 2 in size S however, (Other sizes could have different feel) have a slight pitch back upon entry but at my loadings it quickly goes forward again and through the airmass.

I flew the Blacklight 2 in turbulent conditions, and i could sense a middle B in terms of dynamic reactions. It doesn’t feel like a high B nor as a soft low B.  I think it sits in the middle of this huge category in terms of piloting.

Doing some glide comparison with high and low B’s puts the Blacklight 2 size S at 90 all up in the first middle* of this large category. The second part holds the high B’s with Mentor 4, Iota..etc..

The climb rate however even loaded at top, is excellent on the Blacklight 2 ! This glider could be inserted in the second part of the B category for it’s superb climbing ability. I was always climbing very quickly among other nice climbing gliders.

The top speed on the S at 90 all up is 9 ~ 10 km/h over trim speed which i forgot to mention that it’s quite nice around +39 km/h ! taken at 1000 ASL .
Big ears are super easy efficient and reopen immediately on release.

Conclusion:
It is clear to the eye that U-Turn decided to deliver a new Blacklight with a different philosophy. The Blacklight 2 is more comfortable to fly than the first version .The gene of the bL1 in climb rate is present on the second version. The thick lines seems to be installed for durability rather than thinner more delicate or unsheathed thin ones…The efficiency for the Blacklight 2 into wind is slightly enhanced over the Blacklight 1.
Lets hope U-Turn will consider a race version with thinner unsheathed lines for some B enthusiasts…

U-Turn (Ernst Strobl) Interview

Mr Ernst Strobl is the chief designer and founder of U-Turn and has been designing gliders and was a competition pilot since the first paragliders emerged !

Ziad: Hi Ernst, can i ask you a few questions regarding U-Turn new gliders for 2017 ?

[Ernst: ] Hello Ziad,
For 2017 we have:
Motor Glider:
- PYLO , competition motor race glider.
(Technical Data and video attached below )
- PROGRESS , intermediate motor glider, technical Data in the email. Very easy start and landing, good performance and efficiency with engine! Awesome handling :-) . The glider is make for right after the School…
- Close to finish is a small Tandem Hike and Fly, 120-175kg Start weight, EN/LTF-B, 4,85kg. We don’t have a name in the moment :-(
A good name for that wing… ? :-)  , yesterday we have past Shock & Load test with DHV.


Ziad: Sure ! I hope we will also get some pretty names from the guys on the forum !  :-)
What can you tell us please about the Blacklight 2 ?

[Ernst: ] Long story… a lot of prototypes, finally we decide to go for a middle EN-B with the flying characteristic.
We have done a parallel testing with an high B, aspect ratio 6.0 and the middle B with 5.65. Finally the performance of the high B was not that much more in comparison with the flying characteristic to the Mid. B … so we decide for the more easy flying!
But we have get a lot of knowledge with shark nose… so this was our base for the next step… :- ) …


Ziad: Any new gliders in the C category?
If so, can you please elaborate a bit on what to expect ? High aspect ratio C? or moderate C for B pilots upgrading?

[Ernst: ] Finally the final sample we plan to use for certification is in production.. In 3 weeks I can tell you more.
Passion 2 project, Certification High-C, aspect ratio 6.8, Performance Top of the C range and will go deeply in the D-Performance… the results of our tests so far
  ;-) …


Ziad: What’s your opinion about having lots of cells for a glider in the low B category. Ex: NOVA Phantom.

[Ernst: ] The glider have a good flying characteristic, easy to start, very good performance in this segment, for me the handling can be better… Personally I’m not sure if this is the way… this concept works only with the very light material, we know all how expensive the material is and how long it will stay stable… so what is when the glider is 2-3 years old, how much the pilots will pay for this used gliders… so it can be a big lost in 2-3 years, very hard to say how the market will act on those concepts.


Ziad: You have been designing wings for a very long time. Do you think there’s lots of potential for improving safety and performance? Are we waiting for better materials? Cloth?lines? or new concepts?

[Ernst: ] my competition glider from 1994 have the same performance as an Emotion 3, EN-A, So I think it will go continues forward with performance and safety, a part will be new materials, new concepts, the race is still not at the end… as you can see in the latest development in the competition scene… Impressive to see what Ozone is doing there.

Ziad: Thank you Ernst !!


Cheers,
Ziad

NOVA Interview (Philippe Medicus) R&D department


A few questions for Philippe medicus head of NOVA R&D department .

1-Ziad: Do you consider the new concept of the Phantom an open gate for future glider designs?
Yes!
Philippe Medicus: I don't think, that the Phantom is going to stay the only wing of its kind.

2- Ziad: What are the benefits of this concept on higher aspect ratio gliders? + 6, 7, 8 AR?
Philippe Medicus: Current competition wings have a similar cell count already.
Adding the complex internal structure of the Phantom would decrease weight and increase dimensional stability.
But compared to the advantage of the concept in the "Low-B Class", the benefit would be a lot smaller.

3- Ziad: Does implementing this concept will increase the speed, the stability, or only the performance?
Philippe Medicus: The concept does not increase the collapse resistance, but the dimensional stability benefits a lot. So the wing stays closer to its intended shape, which increases performance.
A high performance glider tends to gain more speed when pushing the speed-bar with a certain travel, than a wing with less performance.
So it's no coincidence, that the Phantom is a faster than an Ion4 on bar.

4- Ziad: NOVA enthusiast will be able to see a new Mentor 5 with this concept? Any dates?
Philippe Medicus: Currently we are not developing an other wing with this concept. So the Mentor 5 won't be a "Phantom-type" wing.
Sorry - no dates yet, but certainly not this year.

5- Ziad: Will it have an impact on the handling ? Turning ability?
Philippe Medicus: It does have an impact on the handling: The Phantom handles more precisely than any other Low-B glider we have flown. And - to a certain extend - the performance of a wing directly affects the handling. When a glider converts speed into height well, pilots say that you can "feel the performance". That's what the Phantom does more than other low AR wings.

6- Ziad: Could they also see a new Triton “C” with lots of cells? 
Philippe Medicus: We haven't decided yet.

7- Ziad: What do you see in future glider design?
Philippe Medicus: Detailed predictions of the future turn out to be false most of the time. :)
So I won't bother you with any guesses.

8- Ziad: The Bion 1 was almost indestructible! Can you please describe the new Bion 2?
And what will motivate the professionals to fly the Bion 2?
Philippe Medicus: The Bion2 has a lighter bottom sail than the Bion1, which won’t affect the longevity unless landing on a tree... The Bion2 will be just as durable as the Bion1.
Easy take off, easy handling, and good flaring ability for landing, longevity.
Further more it's quite fast with open trimmers and has a lot more performance than Bion1.

9- Ziad: One more question please. Can you describe the new Bion 2? The Bion 1 was a very tough tandem wing, almost indestructible !
Why would the professionals be interested in buying the Bion 2 ?

Philippe Medicus: The Bion2 has a lighter bottom sail than the Bion1, which doesn't affect the longevity. (Except you damage the bottom sail, by landing in a tree)
But besides such an incident, the Bion2 will be just as durable as the Bion1.

> Why would the professionals be interested in buying the Bion 2 ?
Easy take off, easy handling, and good flaring ability for landing. And of course the longevity. Further more it's quite fast with open trimmers and has a lot more performance than Bion1.

Thank you Philippe !

OZONE (Luc Armant) interview

Questionnaire for OZONE R&D designer and Team pilot Luc Armant.

1-Ziad : A new concept of gliders with many cells is emerging with low and high aspect ratio. What are your thoughts about this concept? Especially on moderate aspect ratio gliders ?

Luc Armant: The idea from Nova of proposing a glider for richer intermediate pilot is making fully sense. Any other serious mechanical sport industry is having such product. I have no idea what size is that market for paragliders. High cell number concept: for sure things are not simple like the higher the better. Zeno versus Enzo2 is a nice example showing that not only cell number count (78 vs 101). Not enough cells is not good and too much is not good too, even for performances. What we have experimented is that there is an optimum number of cell for a given design, and that optimum can be very different from one design to another.

2-Ziad : Almost every pilot is talking about the Zeno… The Manual is clear. Since you have flown both now, many pilots would like to know the difference in flying demands and feeling compared to the M6 and the Enzo 2. Can you also elaborate on brake response and dynamism?

Luc Armant: Flying demand and comfort is much closer to M6 than Enzo2. I still find that the M6 is a good wing, relatively safe, performant and without bugs, but the Zeno has more character, is more pleasurable, more exciting to fly. All that is without talking about the gain in performances.
Gliding on the side of an M6 or any other END wing, gives you an extra blast. Brake pressure is much lighter than M6. That’s my favorite brake pressure, and you kind of feel the thermal through your fingers a bit like on the Delta2. It can answer fast to roll input and turn in tiny radius with still nice climbing efficiency.


3- Ziad : Now that the Zeno is finished, any news on the Delta 3 project?

Luc Armant: No news yet, apart from the fact we are still working on that project, amongst other projects. But for sure the longest project ever in ozone !

4-Ziad : I know you already answered the following question but just to answer some pilots questions…Will OZONE see an advantage of building a high cell count on a Delta 3 for example? Or a Rush 5 ?

Luc Armant: Ozone will not see an advantage of building D3 or R5 with more cells than optimum for their design.
We try to build product with only necessary stuff.
It does not mean than the Delta3 will have 20 cells only !!!


5- Ziad: Some pilots said that the M6 and Enzo tendency to cravat are high after a collapse ,So did you make any re-arrangement for the Zeno design ,not to have cravats? or may be less...
Any comments?

Luc Armant: I’m not sure about that comment. And I would need to know what sort of cravat they are talking about. Pilots use the word cravats for many different things.
After collapses, sometimes the M6 or the Enzo2 does a small wing tip knot that you can remove by pulling the stabilo line.
I did not make special arrangement but the Zeno is not cravatting easily. For that reason we decided to remove the stabilo line.
Like on any wing, depending on the air and your piloting, you can have a collapse going to the front (sideways air flow), resulting in the collapsed part of the wing blocked by the air flow in front of the lines. But in that case usually two or three deep asymmetric pumping is enough.
 

 6- Ziad: Anything you want to add concerning the future of glider design?

Luc Armant: Like always, I can only talk about present and past. The future is still to be created.

Ziad :Thank you Luc !

Cheers,
Ziad
