DSSERVO RDS3225 25kg Metal Gear Digital Servo is a hobby-grade, high-torque digital servo used mainly in remote-control (RC) vehicles, robots, mechanical arms, drones, and other projects where precise motion control is needed. It’s a compact servo actuator that converts electrical signals into controlled angular movement.
Specification
Capable of producing up to 25 kg·cm (≈ 25 kg/cm) of torque at about 6.8 V, making it suitable for loads that need strong force at the shaft.
Unlike analog servos, digital servos use a digital control circuit giving faster response, higher holding power, and finer positional precision.
Equipped with metal gears (often hardened and anodized), which are stronger and more durable than plastic gears—especially under heavy loads and repeated use.
Sealed housing helps protect internal electronics and gears against moisture and splashes. Many listings describe it as water-resistant rather than fully submersible, so avoid prolonged underwater use.
