What a surprise for me to discover that Team Losi has already produced yo-yos. According to yoyowiki.org, Steve Brown was hired in 1998 to create a line of yo-yos for Team Losi. They released few models like Da Bomb, Cherry Bomb and Grim Sleeper (With ABEC 3 ball bearings!!!).
For Team Losi, the yo-yos venture only last a couple of years, Steve Brown left Losi in 1999 and Losi discontinued their yo-yos line when Horizon bought them in 2001.
