After test flying the Nexus from Swing, here’s the new EN-B Nyos in M size for a test flight.
The NYOS has a mix of sheathed and unsheathed lines with an average width comparing to other B’s . The construction is neat and its what you would expect from a 2016 glider, to the last detail.
The NYOS with it’s 5.8 aspect ratio is in my opinion the best looking B glider to date. It doesn’t really look like a B glider and my friends frequently asked me if it’s a new C glider.
I flew the Nyos M (80-102) from 92 to 98 all up.
Launching the Nyos is quite easy and smooth with no hard point or even any surge.
At both loadings the NYOS M has a relatively medium to short brake travel with a firm pressure rather than a light one. All that with a fairly nice agility resembling the Nexus way to turn into thermals. The NYOS is tuned for XC use rather than a freestyle use. But the agility is moderate to good !
In the same days flying it, i was top landing and switching to other B gliders (Eden 6, Mentor 4) in order to feel better what glider can offer the most in the conditions of each day, not to mention my flying friends who were also helping on those gliders.
After some flying days i can firmly confirm that the NYOS is a very comfortable glider, that offers sweet and relaxed flights like sitting on a VIP luxury seat and people all over are taking care that you are not being disturbed ! Smile
Well that’s exactly how i can describe the feeling under it !
The climb rate in very weak conditions (0.5 m/s) is not the strongest point of the NYOS, but i felt its just a slight step over the NEXUS in that matter. It hovers a bit and the very comfy leading edge is like a Buddhist monk in a meditation process…Nothing will bother him, without the slightest bite in those very weak lifts.
As soon as the thermals are well homogeneous (+1m/s), the NYOS will climb like any other B around and even if the lift gets punchy , it might get upward quicker !
Gliding power !
After test flying the NYOS, i really don’t know what to believe anymore …Its seems to me, like we are swimming in the marketing river of today's hype and tech stories…
Shark nose…No shark nose…Thin lines all over…Thin Dyneema lines…or no…pure 3 liner or no…I’m really puzzled !
After many glide attempt with the company of the well known Mentor 4, my friends eyebrows are mine were exceeding our foreheads!
Considering that the NYOS doesn’t have a Cleopatra nose, and it’s lines are thicker than the M4 ones, with 3.5 line attachment to the under-surface, and it looks quite robust in construction …Believe me, I have seen a lot of B’s… !
The NYOS is faster at trim speed than the M4 S by 1 km/h , similarly loaded, or even if lightly less loaded (+0.5 km/h ) !
The glide at trim is very similar, the glide at 52 is quite similar…the top speed of the NYOS is 2 km faster…
It looks like the NYOS strengths in glide is the pitch movement ‘self’ control on glides…Cannot say it’s a floater, but a real weapon in compensating the movements in turbulent air, and staying focus on the way ahead!
The speed bar has a moderate pressure, and stepping on it gave me the feeling like when i close the door behind me after coming from a loud party. I like that silence ! Smooth ride in a limousine !
Big ears are easy to induce, they are stable with or without bar and quite efficient.They don’t open by themselves but with a small dab on the brakes they reopen very fast.

Reviews will always be reviews…There will always be positive and negative points on each new glider, no matter what…It depend mainly on the reviewer personal opinion and taste. It’s up to you the pilot to feel if those written words apply to your skills and flying sites.
If the NYOS would be slightly more efficient in weak conditions…Hmmm
For sure the NYOS is and will be SWING biggest success to date, The NYOS is ‘THE’ glider for flying in the strong Alps with a big XC potential for the good level of the B class pilots.
What made me smile:
Glide angle at trim and accelerated
Smooth ride in turbulence
Smooth ride at bar
Speed at trim and accelerated
Easy to fly for a 5.8 ar glider
Beautiful looking glider

What made me Grrrr  ;-)  :
- The climb in very weak thermals (-0.5 m/s)


  1. Hi Ziad,
    Could the low efficiency in weak thermals come from the low flat area for the recommended weight? The M Size is "only" 25sqm for an 80-102 all-up load recommendation, which is small for a 5.8 AR wing, no?
    Though it seems to be comfortable. I usually fly C wings between 24 and 25sqm at 85kg all up (and they are sold for a 70-90kg range), here I would need the 23, which makes me feel I'll have difficulties in our weak winter thermals...

    1. I don't think its weight related in this case...Lots of other things are to be considered. For example a loaded Delta 2 (25sqm) still has the float-ability and the digging through weak lift.
      Cheers, Ziad

  2. Right! I was more meaning that for instance, in the same category, a Iota going up to 100kg is 1sqm more (26, flat). Same as a Mentor 4 (26.1). The Rook 2 (26). The BGD Base is in between (25 up to 95, 26,3 up to 105)...
    So the Nyos is (deliberately) a little bit smaller, faster... and weaker in weak thermals.

    Just an observation, even if or course surface is not the only factor for VZ, specially if A.R. is involved!

  3. Hi Ziad,

    just one question. Can you test the Swing Sensis in the near future? I'm very curious about it. :)


    1. Hi,
      I'll try...though it's a bit difficult at the moment...

    2. Hi,

      I hope you can do it somehow... Fingers crossed. :)


  4. Hi ziad, the best weight for the size M how much for you?..for you is more precise eden6 or nyos??tanks for all!! :-) :-)

  5. Hi Ziad, Would you recomend this glider for a telented pilot with aroun 100 hours comming from an A wing?

    1. I think it willbe fine...
      But your instructor will guide you closer.
