The Zero-G was a highly anticipated offstring yo-yo that never actually hit the market. It was one of Yomega’s first attempts at creating a rubber shelled yo-yo, a effort that would again appear in their Xodus, Crossfire, and Lancer.
Friction stickers and rubber shells seemed to be the two patented items that everyone wanted. Just as companies were trying to work their way around the friction brake pad patent, many were also trying to get around Henry’s patented removable rubber shells patent.
Yomega’s idea was simple, don’t make the shells removable. Which also solved the problem of how to work with soft rubber without it flying off of a high spinning yo-yo. the Zero-G’s plastic shells are assembled over the rubber shells, locking the shells in to place and making removal of the shells impossible without dis-assembling the plastic body.
Those who are familiar with the new “soft-core” process that Yomega are doing with yo-yos like the Crossfire, you may notice similarities between the assembly of the Zero-G and that of the Crossfire.
The biggest technical flaw with the Zero-G would have to be it’s trans-axle system. Yomega decided to use a trans-axle system similar to the Fireball (probably to save money), but the Zero-G’s trans-axle was much narrower. Meaning you couldn’t exchange it’s parts with a fireball or any of their ball bearing yo-yos. Around this time, Yomega really seemed to be into making all their systems incompatible. They didn’t want you to be able to buy a fireball, through in some bearings, and make your own Raider. The parts were all propietary, so that Yomega had full control of their yo-yos. Ultimately, Yomega released that making all their parts inter-changable would only help their sales (open source yo-yos), but not in time for the Zero-G
This one is on eBay right now.
