This 27-tooth plastic pinion gear is an essential component for fine-tuning the gear ratio in Kyosho 1/10th scale electric RC vehicles, specifically designed to precisely mesh with Mod 0.6 spur gears. Crafted from a high-strength composite plastic, it offers a lightweight alternative to metal pinions, contributing to reduced rotational mass and potentially improved acceleration characteristics. Its construction also provides a quieter operation compared to metal gears and can act as a sacrificial part, designed to strip before more expensive drivetrain components like the spur gear are damaged during high-stress situations or impacts.
