Butterfly Amicus Ball Throw Wheel - Upper Robot

Replacement upper throw wheel, used on the two top motors of three-wheel Amicus robots.

• Fits every 3-wheel Amicus: Prime, Expert, Start, Professional, Advance and Basic
• For the top motors only; the bottom motor takes a Lower Wheel
• Sold singly, though changing all three wheels together gives the truest spin
• Set the spacing between the 3 wheels with the Wheel Adjustment Gauge
• Upper Wheels carry an outward-pointing arrow, Lower Wheels an inward-pointing one
