Servo / Actuator Sizes

Width <12mm

Weight 5 - 14g

Ultra Micro servos are a specialised type of servo designed for lightweight and small-scale applications, often used in micro RC aircraft, drones, and other weight-sensitive projects. They are typically lighter and more compact than standard micro servos.

Width 12 - 16mm

Weight 16 - 22g

Micro servos are slightly larger than Ultra-Micro servos and are commonly used in lightweight and compact applications such as small RC aeroplanes, micro robots, and miniaturised projects. They offer increased torque and speed compared to Feather servos.

Width 16 - 19mm

Weight 23 - 34g

Mini servos are larger than micro servos and offer further increased torque and speed. They are commonly used in medium-sized RC aeroplanes, small robotics projects, and applications where a balance between size and performance is needed.

Width 19 - 24mm

Weight 44 - 90g

Standard servos are the most common size, used in a wide range of applications including RC cars, boats, aeroplanes, robotics, and more. They offer higher torque and speed compared to micro and mini servos, suitable for larger models and projects.

Width 29mm - 33mm

Weight 110 – 363g

Giant servos are the largest and most powerful servos available. They are used in giant-scale RC aeroplanes, large robotic applications, industrial automation, and other projects where extreme torque and durability are essential.

Width 21 - 23mm

Height 25-26.6mm

Weight 35 – 68g

Low profile, where height is a premium. These servos are characterised by their compact size and reduced height, making them ideal for installations where space is limited, or weight considerations are critical. Despite their smaller form factor, low-profile servos offer high torque output and precise control.

Width 30 - 38mm

Thickness 8-10mm

Weight 20 - 24g

Slim wing servos are specialised servo designed for use in aircraft with narrow or thin profiles. These servos are engineered to fit into tight spaces within the wing structure while still providing the necessary control authority for flight surfaces such as ailerons, flaps, or elevators.
