20KG Digital Servo with Aluminium Metal Gears (180°)

This 20kg digital servo delivers high-torque actuation for payload release mechanisms, gimbal pan-and-tilt mounts, and heavy-duty RC vehicle steering.

Key features

• Digital control with a coreless motor for precise positioning and strong holding torque under load.
• Hard-anodised aluminium metal gears and a CNC aluminium middle shell resist stripping under load spikes.
• Dual ball bearings and waterproof rubber seals for smooth, reliable operation in the field.
• 180-degree rotational sweep suits parachute deployments, hatch mechanisms, or custom pan-and-tilt mounts.
• Terminates in a standard 3-pin JR/Futaba-style connector for direct wiring to a flight controller or PWM receiver.

Specifications

• Rated torque: 20 kg·cm at 4.8 V
• Operating voltage: 4.8-6.0 V
• Travel angle: 180°
• Control signal: Digital PWM
• Gear material: Aluminium
• Weight: approx. 55-60 g

Ensure your flight controller's BEC or an external power module can supply enough continuous current — high-torque digital servos draw significant peak current when stalling or working under heavy load.
