Servo type determines the size and power of an RC servo, affecting its suitability for various applications. Selecting the right servo type is crucial for achieving the desired performance and compatibility with your RC model.
Popular options (you can select more than one)
Mini servo
Typical price
25.– to 76.–Smaller than standard servos, offering a balance between size and power for compact models.
Suitable for tight spaces where a standard servo would be too large, like in smaller planes or drones.
Bestseller
Micro servo
Typical price
14.– to 38.–Extremely compact and lightweight, designed for small and lightweight RC models.
Best for applications where weight and size are critical, such as micro drones or small robotics.
Bestseller
Midi servo
Typical price
25.– to 40.–Intermediate size between standard and mini servos, offering a blend of power and compactness.
Perfect for models that require more power than a mini servo but less space than a standard servo.

Servo speed refers to the time taken by the servo to move to a specified position, affecting the responsiveness of the device it controls. It is crucial for applications requiring precise and rapid movements, such as in robotics and model aircraft, where quick reaction times can enhance performance and control.
Popular options
Up to 0.1 s
Typical price
38.– to 100.–Provides exceptionally fast response times for immediate adjustments.
Ideal for high-speed applications like racing drones and fast-moving robotics, ensuring quicker control and precision.
Bestseller
0.11 - 0.15 s
Typical price
29.– to 85.–Offers a balanced speed suitable for moderate speed applications.
Perfect for general-purpose robotics and model aircraft where a quick but not ultra-fast response is needed.
Bestseller
0.16 - 0.2 s
Typical price
33.– to 68.–Delivers slower response times compared to faster options.
Suitable for tasks where speed is less critical, such as precise positioning in hobbyist projects and educational kits.
