💡 What is a pinion gear used for in RC cars and how does 0.8 mod affect performance?

In simple terms, the pinion converts motor RPM into wheel RPM, shaping top speed and torque.

• Choosing the right module and tooth count changes the gearing ratio for desired speed and torque
• Pairing with a compatible spur ensures proper mesh and drivetrain longevity
• Secure the set screw with thread locker to prevent slipping during hard runs
