Winex Nanofly Synthetic shuttlecock Review "kind of"

This Nano fly "review" will continue to be updated during the development process
until we reach the goal and a final commercially version is available so keep this in
mind when you are reading about this product and its different development phases.

Synthetic shuttles some Back ground talk

Well while we are still waiting for the breakthrough of the carbon fibre feather shuttle
that to 100% mimics the flight of a perfect goose feather shuttle at a fraction of the
price and with a lifespan of 10 goose shuttles we have to se what's going on in the
nylon polymer shuttle development :0)

Years ago Dr Alison Cooke wrote a Thesis on Shuttlecock Aerodynamics & Mechanics
that was a stage in the right direction of the understanding of the complex function
of a badminton shuttle aerodynamics and flight characteristics.

In March 1994 The New Scientist wrote a report that stated:"More than forty years
since the invention of the synthetic shuttlecock, players at next week's All England
Open Badminton Championship in Birmingham will still be using goose feather designs
dating from the early part of the century. Top players and coaches say manufacturers
have yet to produce a synthetic shuttle that's as good as the real thing. But now
manufacturers are hitting back. They're beginning to work out why feathered flight is
so difficult to copy and claim that within 18 mt a new generation of shuttlecocks with
carbon fibre 'feathers' will transform players' attitudes."

We are still waiting by 2011!

Update Version #3+4 Tested (August 2010)(updated 5/9 2010)

The newest synthetic cork Nanofly arrived in a red tube and the real cork
version in a signal green colored tube.

They both came in speed rating 77 (Marked on the tubes)

Winex Nanofly real cork base version
Left - V2 tested below. - Middle the latest syntetich cork version. -  Right the real cork version.

The new Winex Nanofly samples has just arrived and they looks impressive.
I have now ben able to get time to test the new versions.

The first impression I get when I squeeze and look at the new samples
is that the cork head version looks and feels rely impressive.

I also noticed the new reinforcement ring in the skirt mould close to the cork base
(Red arrow in the image) this should help the durability and is introduced in both of the
new versions I received .

How they play.

The new version with synthetic cork

(This is the best version I tried so far and better than the nature cork version)

+ Speed was nice and close to the 77 speed rating marked on the tube.
+ Feels nice to hit.
+ Smash and drop shots can be performed with desirable result.
+ Steams doesn't brake close to the cork like the earlier version (Thank's to the redesign with a      ring close to the base)
- Still brakes quite fast in the mid part of the skirt (Probably due to sharp corners in the mould ??)
- Aerodynamic design not yet fully developed the shuttle suddenly and randomly
  stops to propell (Spin) and flight is unstable.
- Strange behaviour wobbles in a funny way if you slice your stroke (I newer seen this in any     other synthetic or feather shuttle.)

The new version with nature cork

(First real cork NanoFly version I have tried)

+ Greater look and quality feeling than the synthetic.
+ Better durability than the synthetic version (Why? the skirt design appears to be the same.)

- I received this version in a tube marked with speed 77 as well, but it is much slower    than the 77 speed I'm used to play and also much slower than the synthetic 77    speed NanoFly version I received at the same time.
   I had this explained by Winex later, the shuttles I received was actually a 76 speed
   version aimed for the Asian market and my tube got the wrong marking.
   (It Would be nice to try the real cork version in 77 and 78 speed :0)
- In fact the real cork version 76speed sample I tried was far to slow to judge in
  a fair way.
- Same stability problem and problem with propelling randomly and suddenly stopping.

Red arrow point at the weak point where it breaks.

A smother transition in the mould should probably help to solve this issue.

Red arrow shows the feather part of the skirt.

A redesign of this part should probably help to solve the propelling and instability issue.

The small wire/resistor in the image was used to squeeze the damaged shuttle in a way so it is easy to get
a view of the damaged parts of the shuttle, in real life the shuttle kept its shape in a way so it would be hard
to capture the damages with a camera.

test of the V3-4 has ben performed this week and I would like to add some
comments about that.

The above shuttle was played for two complete games of double (21-17, 21-15).
Arrows and numbers show the weak points of the design in regards of life length.

1. The skirt "Feather part"
2. The upper steam support ring (as mentioned above)
3. The mid support ring brakes where it meets the steams.

After a few games with the Nanofly we reverted back to the good old Yonex Mavis 350.
I was surprised over the difference, the 350's had a much different way to fly and I
experienced that when I smashed the Mavis 350 it went like a rocket compared to the
Nanofly that slowed down faster and allowed the defending team to return quite a few more smashes.

The short serve also behave quite differently in regards of Nanofly vs Mavis 350
the 350 was traveling in a longer arc compared to the Nanofly which dived in a way
much closer to the real thing (read feather) than the 350's.

Then Nanofly in my version #3 with synthetic cork is the best version I tried so far
It still have some issues that has to be solved before it reach the shelves however
I was happy to see that they now last longer than before, I'm also pleased to see that
even if they brake a little here and there they still behave nice and play almost as if
they were new!!

The biggest problem right now is the sudden stops propelling issue which in fact is
mostly a psychological problem since the shuttle appear to be stable with or without
propelling it also appears to travel at the same speed in both propelling and static


Still many minuses, however they are fewer then before.
For the next version I hope for a redesign of the aft part of the skirt (feathers)
to solve the stability and mechanical rigidity plus the propelling issue.

Winex Nanofly in two different development stages
2nd version marked 10.5.5 - 1st version 20100415.
Pen marking was made by me to keep them apart.
I just received the version #2 of the Nanofly shuttle cocks from from
Mr HY Wang at Winex.

Mr Wang says that the sample I received before
wasn't´t the final version
so I will retest the
Nanofly in Version 2(Beta!)

I also hope to get some samples of the Version #3 that might be the final production quality version, I have been informed that they then will be
equipped with a natural cork instead of the Alpha and Beta synthetic "cork"

My first impression of the new version (By looking at them and holding them in my hand).
Is that they probably will last longer, the polymer in the "feathers" are now
a bit softer than the V2 but still stiffer than the Mavis 350 and 2000.
Otherwise they look the same as the V1, I played them on Friday 27 May 2010.

I can confirm that there have been some development done on this second
version that I have had the opportunity to try out the durability has increased
and I didn't experienced any steams broken close to the "cork" like they did
in the first edition.

When they brake it is mainly in the aft part of the skirt and the brake in a
way that looks pretty much like the first edition.
However I got a feeling that it took quite a bit longer until they started to
to crack down and become unplayable.

This is how it looks after
about 1 1/2 game.

Not much to say in regards
of durability any longer
since this is about the life
span we have learned to
accept from any quality
plastic shuttlecock.

How do they play then?
Well the impression from the MK1 are still valid and the MK2 fly and behave
exactly the same, sounds the same and they still stops to spin now and then
and still feels a bit heavy to hit.

The 77 speed samples that I have tried are faster and fly longer than the
350 and 2000 Mavises in Medium "Blue" speed that I normally use when I
play plastic and they also go further and faster than a 77 feather shuttle.
However this is not a big problem since the Nanofly comes in several slower
speeds than 77 which is the 2nd fastest so it should be easy to find a
suitable speed for every situation.

I still feel that Winex still have some work to do on this shuttle un till they
are ready for shipping but they are on the right way, maybe the real cork
head will change the behavior in a way that make it perfect we just have to
wait and see, I would also like to have the aerodynamics changed a bit to
solve the behavior of the shuttle suddenly stop spinning, since I found that
a bit disturbing and strange.

However I'm already looking forward to the third edition real cork head samples and the possible step forward in feel and sound that might be
the benefit of a real cork head.

Stay tuned / Stefan

Below this level of the page you will find the result from the V1 (Alpha stage) Nanofly test.
Use it for reference only and not for judging the final product.
All the new stuff will be found At the top of this page as the review will go on.
And the final judgment of the final version will also be found at the top when time comes!

Winex Nanofly Badminton shuttles, the tube package

Winex Nanofly Shuttlecocks is suppose to be "Just like real feather shuttlecocks"
They come in 75, 76, 77, and 78 speed. My sample tube came in 77.

If it is the "First innovation in the world" then it might save some birds in the future!
I will try to find out....


The Winex Nanofly shuttlecock    

Fingers and eyes says this is a cheep synthetic toy shuttle and i must say most of the
synthetics I have held in my hand has been better looking.

Anyhow the looks isn't the most important thing so lets hope my worst thoughts will
fall down in shame

Winex shuttle fron face

The synthetic cork in a fighting view, there are some irregularity's in the surface
but nothing that will have impact on the precision of the strokes but but....


The secret key according to Winex is the fixing point of the skirt that is closer to the
edge than the competition (Yonex?) Winex also state that they use NanoNylon for the skirt/feathers [Read more about NanoNylon Here!]

Winex Nanofly Vs Yonex 350
Compared to the Yonex 350 the Nanofly skirt is fitted much closer to the edge.
It is also attached in a more "Feather like" way.

Yonex Mavis 2000 skirt to cork interface

The competitor Mavis 2000 has the same skirt to cork interface as the 350 and 370 from the same company so there is something unique with the Winex Nanofly after all!

A even closer look at the synthetic cork, not as smooth as I would have wished for.
But again, it is the way it feels when you play it that counts.

Winex Nanofly smash and clear flight curve
Flight characteristics in accordance with Winex Nanofly Europe web site.

My impressions of the first evening of playing the WinexNanofly!

This was suppose to be the evening we first played the Holy grail of synthetic
shuttle cocks the one that was claimed to have the "Winex Nanofly Impact sounds like 80% real feather" as stated in there catalogue.

And a flight much closer to the real thing (Feather) than any previous synthetic.

I got a mixed feeling and experience of those new shuttles, they played quite well.
They felt a bit heavy when you hit them but light in your hand!?
the sound was sharper and harder than the Mavis 350 that have a very damp sound
but It didn't sound like the real thing, I don't know what 40 or 60% of real feather sounds like so it could have been 80% but no no no not like the real thing :0}

Closer to feather in fact than the Mavis 350 it has a more constant speed, not like
the Mavis 350 that goes rely fast (to fast) when you hit it hard.
This is probably due to the stiffer skirt of the Winex Nanofly and maybe also due
to the different geometry it gets by fitting the skirt closer to the edge of the cork.
But again you probably wouldn't ditch feather after trying the Nanofly.

When I hit the Nanofly for a clear it feels a bit heavy it also sometimes stops
spinning, this looks weird because it sometimes spins just fine and sometimes
after a virtually exactly the same stroke flies without rotation!
My sample was delivered at speed 77, however the traveled quite a bit longer
than the RSL Classic at same speed that I used for reference.

Built Quality:
All of my samples was traveling straight and was very close to each other in flight
so the quality seams to be even and high in regards of consistency.

Durability (Not the same thing as quality)
Compared to the Mavis 350 the Nanofly seams to last about half as long until
the shuttle was "unplayable" however I also felt that it kept it's initial characteristics
for a longer time than the Mavis 350.

Compared to feather (RSL Classic) the Nanofly of course lasted longer but still I
expected higher durability from a synthetic shuttle than I got with the Nanofly.
This is probably a result of using a stiffer polymer in the skirt to obtain the advantage
of having a smash speed curve being closer to the feathers than the Mavis 350.

I have also played the new Yonex Mavis 2000 and my experience of them are
that they share some of the things with both the good old 350 and the Winex Nanofly
and mix it in to what I consider to be the best of two worlds.
The playing and change characteristics of the Mavis 2000 is close to the Winex Nanofly
than the 350 and the durability closer to the 350 than the Winex.

Conclusion&final verdict:
I was tempted to become the Scandinavian General Agent for the Winex Nanofly
in fact I was asked to, however I feel that Winex is on the right way in some respect
but still not there, so I pass this time.
I still hope they keep up their work and development and maybe in the future we will
play plastic even in the Olympics (Either by highly developed synthetic shuttles or by international boycott of feathers due to the birds benefit!)

Winex Nanofly broken

Skirt broken on Nanofly
   To the left and above. 
   2 sets of regular single play wit some but not
   extensive smashing the shuttle was now
   unplayable and wobbled uncontrolled a
   replacement was necessary.

   To the left
   The 2nd shuttle lasted for about a 20 stroke    rally and then started to behave strange.

   When examined, several "Feathers" was
   found broken close to the "cork" base.

   This one actually behaved like a real
   feather shuttle in regards of life length :0+
