http://www.badmintoncentral.com/forums/showthread.php?t=607&highlight=t-joint as far back as i can remembered, yonex patented the internal t-joint. The rest of of yonex new technologies are just trademarks.
Is this the patent, mr cooler? http://www.freepatentsonline.com/4575084.html?query=Yonex&stemming=on Is the patent still valid or expired? (normal patent last about 20 years?) Cab20 was like almost 1980s. The patent was published in 1986. Which explains why the Arcsaber 7 was created with novel plastic t-joint.
I don't think so. Arc Saber is still most durable. Nonetheless, you can easily string the NS9900 to high tension as 30 x 30LBS without breaking it. But.... there is always a but.... it may go slightly out of shape... Thanks.
How I wish this really were common knowledge. If so, people wouldn't fall for such marketing gimmicks If you are into the complex chemistry of such molecules, here's some reading (which, although old, is still relevant and valid): 1. Fullerene Chemistry 2. Fullerene Science Have fun
I think Yonex reagrds their top 3 AT models, AT700 and the 2 AT900s as the most durable of their high range racquets. But Yonex's most durable racquets are two lower models with an aluminum frame and one with a graphite shaft and the other with a steel shaft. The AT700 and AT900s also have the highest recommended string tension of all Yonex racquets, exceeding those recommended for the ARCs, the NSs, and all the Ovals.
If you compare AT700 and AT900s, you will see that the head is physically thicker compared to ARCs and NSs. So I guess they would be stronger for sure. But i've tried playing with them...feels bulky to me. I prefer slim heads like the Ti-10 or the NS9900.
My Nanospeed 9900 has already suffered a clash... and survived it Luckily, since both of us were lifting the shuttle, it was not the usual 'meeting of racquet heads at different speeds'. Personally, I have found the AT-700 to be the most brittle or fragile of the lot, followed by the Ti-10 and the ArcSaber 10. These racquets have proven to be extremely nasty to my wallet For unbreakable quality, I recommend an ancient all-steel monster
new as in new thing to their technology list on their site, because it wasn't on there before this racket came out. i can care less what they say. lol. i just like learning new things sometimes. i don't play enough badminton to buy a 200 racket anyways (although i really want one). i got two fake yonex from ebay and thats all i need for now. they play super well actually. man do i miss badminton. haha. they've been doing that for a while now.lol. i play up to 21 but not rally style.
yonex replaced the metal T with a hard plastic to lighten up the head, Patent is good for 17 years i think. The Uruguay Rounds Agreements Act (Public Law 103-465), which became effective on June 8, 1995, changed the patent term in the United States. Before June 8, 1995, patents typically had 17 years of patent life from the date the patent was issued. Patents granted after the June 8, 1995 date now have a 20-year patent life from the date of the first filing of the patent application. However, the effective patent term is frequently less than 20 years because patents are often obtained before products are actually marketed. Many factors influence the length of the effective patent term, including the requirements in the Federal Food, Drug, and Cosmetic Act and the Public Health Service Act that certain products receive FDA approval before marketing.
Most of the players didnt have chance to test out the NS9900 when they are in Europe. Only few. Tan Wee Keong saw the new Ns9900.. but didnt have a chance to try it out as well. Only today he got to check it out from me. kinda funny.
Just received my 9900 today! NS9900 + NBG98 @ 20 lb + Wave Grip + free Yonex 3 racket bag. (USD 260). I have played with a NS9000 (w/ NBG95) for over half year. I liked it a lot. It is an excellent racket for both defense and offense. I can't wait to go to badminton tonight to try out the 9.9k! From the feel of it now, it is a bit lighter and easier to manoeuvre than the 9K. Hope it will perform better in action.
