💡 What is a pinion gear used for in RC cars and how does it affect performance?

A handy component that connects the motor to the drivetrain, setting gear ratios for torque and speed.

• In RC cars, pinion gears transfer power from motor to spur gear, controlling torque and top speed
• They must match the gear pitch (MOD1) and bore (5 mm) for proper fit
• A set screw keeps the gear secure on the motor shaft
• Common in 1/8 scale MOD1 builds for precise tuning
