Japan's Kawamae Hits World's Fastest Shuttle With an impressive speed of 414 km/h. That's almost 260 mph. http://www.badzine.info/index.php/f...-kawamae-becomes-worlds-fastest-shuttler.html I think two things contribute this new record: 1. New Yonex Arc Saber Z-flash racquet 2. It is done in a testing, not a real match
In fact, there is already a thread open on this topic in the Equipment forum, though the topic is the racquet, not Kawamae.
