1. shuttlecock speed specifications

i experienced two shuttlecocks flying at different (serving) distance in a
single session. i had a difficult time varying my strokes.

i think it is important that we practise wif the proper shuttlecocks
of correct speed.

articles pertaining to shuttlecock speed (and weight) states that there
r 3 common system 2 rate the speed of the shuttlecocks:

international --- metric wt.-grain - speed
eg.
1 --------------- 48 ---- 75 - slow, for use in highland

however, i had searched in vain to find out where 2 look out for these
specifications when buying a tube of shuttlecock...

can anyone help pls??

2. a simple search could've given you these links:

try to do a search first, that's why its there.

enjoy

3. shuttlecock speed specifications

hi sessyargc,

i have 2 apologise 4 my poor description...
i did a search and had read the articles and forums b4 i post my question
on this matter...

what i would like to ask was:

-where do we find the specification (speed/weight) on the tube of shuttlecock?

for a few days, i went around some sports stores and found out that:
-some (yonex) tubes of shuttlecock have a number
(of international standard 1 to 5) next to their barcode.
-some have small stickers with the international standard (1 to 5) on the
plastic (flat) cover at one end of the tube.

-if there are no stickers or numbers pasted or printed to indicate the speed,
are there other methods to determine the speed of the shuttle?
(this also applies to shuttlecocks shown on the net)

-the article (from the above link), states that the heavier the shuttle, the
faster and further it will travel.
i always thought that the shuttle travels faster and further because it
is lighter... i just need to confirm on the information.

"A 74 will travel 10 to 15 cm less distance than a 75"
while the article above (1st link) states that
"There is a 30cm distance between each speed"
A distance of 10 to 15cm is a great deal, let alone a 30cm... so which one
holds the correct information???

4. I guess I also misunderstood your question. Let's try to straigthen this thing out shall we.

You asked: -where do we find the specification (speed/weight) on the tube of shuttlecock?

Now that is tough as Ive seen several shuttlecocks here in the Philippines with no marking. I couldn't recall if the Kason KS-77 I bought had a sticker.

Yes indeed RSL and Yonex tubes have stickers but they differ in the "number" presented. Yonex uses the newer nomenclature (1-5) (i think) while RSL uses the older style (48-52).

I think the rule of thumb to remember if you're concerned about the speed of the shuttlecock is to buy only properly marked tubes. (This is the reason I only use RSL nowadays)

Since I'm not a club level player I don't usually concern myself of the actual speed of the shuttle (as written on the tube, as long as theres a good shuttle I play ). If a shot goes long with my normal stroke, I adjust.

I think some of the more experience members of the forum could enligthen both of us regarding your last couple of questions.

Shuttles slow down because of the Force of air resistance.
The deceleration (according to Newtons F=ma) will be Force / Mass

If you assume that heavy and light shuttles have the same air resistance (from the feathers) then the deceleration will be smaller for a heavier shuttle.

Something that decelerates slowly travels further than something that decelerates quickly.

Compare it to scrunching up a piece of paper into a ball the size of a baseball.
You could throw a real baseball much further than the paper ball.
Same size, same air resistance, different mass.

If you are absolutely have to buy a tube of shuttle without speed indicated on the tube from the shop (surely there must be other shop that you can get one from or change brand), then one of the way is to test the speed of shuttle (this requires you have to buy one tube first ), see ( http://www.intbadfed.org/Portal/documents/laws2002.pdf )
and you can tip the shuttle so that you can change the speed, see ( http://www.badders.com/resources/shuttle.html )

HTH.

7. ok, being the dealer for SeaLion here in the Phil. lets see if I can help a bit...

international-metric wt.-grain - speed
1 ------------- 48 ---- 75 - slow, for use in highland
2 ------------- 49 ---- 76 - medium slow, for use in hotter area
3 ------------- 50 ---- 77 - medium, most sea level area
4 ------------- 51 ---- 78 - medium fast, cold area
5 ------------- 52 ---- 79 - fast, cold area, below sea level

Bigfatfish ... look for the corresponding value that best match the climate you are in.. different manufacturers have different ways of classification. As you see above.. a tube from manufacturer A rated at 3 should be equal to a tube from manufacturer B rated at 50 and also equal to a tube from manufacturer C rated at 77.

@ Sessy - (musta)there are other brands properly marked in our market.. not only RSL. Chaopai, Yonex, Aeroplane SeaLion etc are usually properly marked..

hope to have helped..

regards

I might be wrong, but with personal experience, i feel like 49 should be at least 77, while 50 should be at least 78 range.

9. shuttlecock speed specifications

thanks to all who supplied wif their knowledge and experiences. all ur replies r very valuable.

regarding LazyBuddy's query,
i did a search on speed specs on search engine, but
it seems the only reference on shuttlecock speed is from the article stating:

international-metric wt.-grain - speed
1 ------------- 48 ---- 75 - slow, for use in highland
2 ------------- 49 ---- 76 - medium slow, for use in hotter area
3 ------------- 50 ---- 77 - medium, most sea level area

but quoting from jayes, i guess we should get the correct type (through trials)

TESTING A SHUTTLE FOR SPEED
3.1 To test a shuttle, use a full underhand stroke which makes contact with the shuttle over the back boundary line. The shuttle shall be hit at an upward angle and in a direction parallel to the side lines.

3.2 A shuttle of correct speed will land not less than 530 mm and not more than 990 mm short of the other back boundary line as in Diagram B.

I will say, this article either is mis-leading due to certain mistakes, or it's different manufactures somehow has its own standard.

Fellow Manilans,

Ive used both RSL and Aeroplanes who use the 40 series and 70 series specs respectively and I think we can agree that this is the "default" for use in Manila.

From that chart, it should be ok to use 50/77 speed shuttles during the cooler months, say November to Feb. Can anyone tell me if they've done so? I've usually rejected speed 77s and 50s out of hand so I cant say Ive tried them.

Pball, could you post the Manila SRP of your Sealions and your dealers in the Marketplace section? I find RSLs expensive these days and for some reason I find Chao Pai #1s to be a bit fast.
