The Savox B-12KG is a budget-friendly standard-size analogue servo designed for general RC applications that need reliable control and stronger metal gears. Producing up to 12.0kg-cm of torque at 6.0V, it is a practical choice for RC cars and other hobby models where a dependable standard servo is required without moving into higher-priced digital servo options.

Built with a DC motor, heavy-duty metal gears and dual ball bearings, the B-12KG offers improved durability over plastic gear servos while remaining an affordable option for everyday RC use. Its higher torque output makes it well suited to basic steering setups, RTR servo replacements and general applications where extra holding power is useful.

The B-12KG also features a 25T output spline, standard-size fitment and a simple analogue control system, making it a straightforward replacement or upgrade servo for many RC models.
