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

This standard-size 20kg digital servo delivers high-torque actuation for payload release mechanisms, heavy-lift drone camera gimbals, and large fixed-wing control surfaces. Equipped with a fully aluminium gear train, it resists stripping under heavy static loads and aerodynamic stress better than composite alternatives.

Key features

• Digital control circuitry ensures precise positioning, tight deadbands, and strong holding torque under load.
• Aluminium metal gears engineered to handle aggressive load spikes in custom mechanisms.
• 180-degree rotational sweep ideal for parachute deployments, hatch mechanisms, or custom pan-and-tilt mounts.
• Terminates in a universal JR-style connector for direct integration with standard flight controllers and PWM receivers.

Specifications

• Rated torque: 20 kg·cm
• Travel angle: 180°
• Control signal: Digital PWM
• Gear material: Aluminium
• Spline: 25T (Standard)

Ensure your flight controller's BEC or an external power module is rated to supply sufficient continuous current (typically 2A+ per servo at 5V-6.8V), as high-torque digital servos draw significant peak currents when stalling or operating under heavy loads.
