💡 What is an RC pinion gear used for in hobby-grade cars and trucks? It translates motor torque into wheel movement and sets the drivetrain’s speed and torque. - It defines gear ratio when paired with a spur gear - Safe-D designs help prevent drive loss if the set screw backs out - Material and tooth geometry influence wear, efficiency, and noise - Works with standard 5mm shafts used in many RC motors
