Castle Creations CC PINION offerings are expanding and now include 1:6 and 1:7 scale applications! These mega-strength pinions are machined from carbon steel and will have a good resistance to wear and tear with their case-hardened finish. The result is a performance pinion that can take the extreme conditions large-scale RC cars operate in.
