Yes, I am biased (aren't we all more or less?), but always open to new knowledge, and facts And I did not take the Yonex rep word as is, thats why I was asking you if you had any solid figures on weights... Which maybe even could be interesting given the original posters question in the thread /T
I just opened 1 tube of M300 and 1 M500, Sorry, I do not have M350 at this time. avg of 2xM300 = 5.05g avg of 2xM500 = 5.10g Please note that the skirt of M300 and M500 are different. I might get a M350 this weekend to do some measurement and see the BP also. I will not do flight test because my swing might not be consistent.
Nice , Cooler-Yonex 1-0 (and btw thx for the effort, & info ) Did you weigh them separately and averaged? any deviance between individual ones? /T P.S. it could be interesting to compare this to the weight of international-tournament-shuttles (feather). where 5.0 gram would be a speed 77 shuttle, and 5.1 gram would be speed 78. so that would mean 5.05 would be 77 1/2 ... D.S.
Dear T, The shuttles are weighted separately then average. Deviation is 0.1g for M300. 0.0g for M500. I will try to get a tube of M350 and weight all 6 shuttles in each 3 model this weekend. Dear Cooler, They are med speed. You know me and you already knew the answer. Thank you for the reminder. I love scientific investigation... Good night gentlemen.
How come the Greatest GrandMaster SH is doing all the work? What/where is the other great scientific mind doing?
Shutter speed designation used to come in 48, 49, 50, 51, 52, etc to denote its weight 0f 4.8g, 4.9g, 5.0g, etc. This was not a very accurate classification so the current speed classification of 75, 76, 77, 78, etc is preferred. This system uses a 30cm distance difference between one grade and the next speed grade. Surprisingly this system was in use many years ago, even by nylon shuttles which used to come in speed grades of 76, 77, etc. Both the weight and the diameter of the feathers shuttlecock are the major factors in shuttle speed.
So according to cooler 350 is heavier than 300, and 500 is heavier than 350.. But the measuers from SH seems to contradict that as 500 seems only slighter heavier than 300.. So how could it be heavier than 350? Or is this just incosistensys because of these shuttles being so cheap /Twobeer
How about testing Mavis 300, 350, 370, and 500 for speed on the courts? Do they land within a distance range of 46cm, measured from a point 53cm from the back boundary line towards the front?
That "test" seems kind of silly, as conditions like humidity, temperature, sea-level etc. will affect the result , Thats why they are made in different speeds in the first place , so in essence at one venue a "medium" 350 may have the correct speed, on another it will not... If any of the 3 speeds available are not good for the venue, there is no solution to adjusting the speed permanently on these plastic shuttle . /Twobeer
can tell that you are familiar with plastic shuttle. hm.... SH weighted the medium speed (blue) cooler weighted the slow speed (green) will it be difference?
To Taneepak, Yonex can produce very consistent plastic shuttle so by controlling the weight of shuttle, it can control the speed and distance. This is something feather can not reproduce. The test you asked, I am not Arnold not a cyborg. I can not produce a serve with exactly the same force and stroke every time nor I have a machine to do that. So the test you requested is very silly indeed. If you really like to see the test, please cntact your friend at Yonex if you still have any.
If Yonex plastic shuttles are consistent in weight and speed (distance), it is then very easy to test its speed in the court. That is how players test shuttle speed to ensure the correct speed shuttles are used. All I am asking is for someone to test a tube each of the Mavises they have in the courts. I believe you are familiar with how to test for correct shuttle speed in the court. I always test shuttle speed whenever I go to a new venue or hall to play. You do not require Yonex to field test plastic shuttle speed. If all the Mavis in the same tube falls within the distance range, then you have speed consistency. Weight consistency, so long as it is within the accepted deviation, is not as important as speed consistency in the acceptable distance range for plastics and for feathers also.
Silentheart, you do not use the serve to test shuttle speed. Using a serve will give you false results.
Wow, I am speech less now. Under rule 3.1 I really don't know what to call that except a forehand serve. 3.1 To test a shuttle, a player shall 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. Yes, I know how to test a shuttle speed. I just want to take human factor out and reduce the variance. 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 try not to make any statement that is too general that is waste of time.
let's not to carry away from thread title. just stick to the difference between Mavis 350 & 500, maybe can include Mavis 300 as reference..........
if bwf approve mavis for tournaments, i'm very very sure yonex will comply and make more speeds for mavis product line. Better yet, yonex would even keep improve them.
