💡 What is a pinion gear used for in RC cars and how does Safe-D design boost reliability?

Safe-D design helps prevent drive loss, keeping power transfer secure. - It translates motor torque to the drivetrain by meshing with the spur gear. - The D-shaped hole keeps shaft alignment even if the set screw loosens. - Retention hardware (M4 screw and E-clip) improves reliability during high-stress runs.
