💡 What is a pinion gear used for in RC and light machinery?

It's a handy drive cog that transfers rotation from a motor to a gear train, enabling controlled speed and torque in a compact setup.

• Transmits power between motor and spur gear with reliable mesh
• Helps tune gearing for the right speed and torque
• Easy field maintenance and part swaps
• Common in RC cars, small automation, and hobby projects
