The Tom Kuhn RDX prototype from sometime in 2016. Made by CYYC (Chico Yo-Yo Company) out of Chico, California for Tom Kuhn Yo-Yos. Unfortunately, the yo-yo was never put into production because the makers could not get the yo-yo design to be properly balanced.

The prototype in this exhibit is interesting. It uses a completely different bearing hub than the other prototype in this museum. This variant has a flush inner aluminum hub with response pads and a ball bearing axle. The entire inner hub assembly was then combined with maple body halves that had outer rim weight rings installed.

The entire "greeked" design on the outer face -- with the exception of the Tom Kuhn infinity logo -- was laser printed on paper and held in place by the weight ring. Ten prototypes -- each one apparently slightly different from the other -- were supposedly made.
