Servo type is a crucial factor when selecting an RC servo, as it determines the size, power, and application suitability. Choosing the right servo type ensures optimal performance in your RC projects, enhancing control and responsiveness during operation.
Popular options (you can select more than one)
Mini servo
Typical price
25.– to 76.–Smaller in size and weight compared to standard servos, making them suitable for compact applications.
Perfect for lightweight models, such as small drones or micro cars, without sacrificing performance.
Bestseller
Micro servo
Typical price
14.– to 38.–Designed for ultra-lightweight applications, typically offering lower torque and speed.
Best used in mini RC models or projects where space is limited, such as tiny airplanes or mini robots.
Bestseller
Midi servo
Typical price
22.– to 40.–Falls between standard and mini servos in size and torque, providing a balance for mid-range applications.
Great for medium-sized RC vehicles or robotics where a standard servo may be too bulky.

Servo technology refers to the type of signal used to control the position and movement of the servo motor. Understanding this factor is crucial as it affects the precision, responsiveness, and overall performance of remote-controlled applications such as drones, cars, and robots.
Popular options (you can select more than one)
Digital
Typical price
40.– to 100.–Digital servos use a pulse-width modulation (PWM) signal for precise position control, resulting in faster response times and improved accuracy.
They are ideal for high-performance applications, like racing drones or robotic arms, where quick adjustments and precise movements are essential.
Bestseller
Analogue
Typical price
14.– to 33.–Analogue servos operate using a simpler PWM signal, providing basic control over position and speed, making them generally easier to set up.
They are well-suited for applications where high precision isn't critical, such as in toy models or basic RC vehicles.

Moment of force, or torque, is a critical factor when selecting RC servos, as it determines the servo's ability to move or hold weight. Higher torque ratings allow for more demanding applications, ensuring that the servo can handle the specific requirements of your project, such as steering a heavy vehicle or controlling larger mechanisms.
Popular options
Up to 15 kg/cm
Typical price
25.– to 76.–This torque range is suitable for lightweight applications, such as small RC cars or basic robotic arms.
Ideal for beginners or projects that do not require heavy lifting, ensuring ease of use and lower power consumption.
Bestseller
16 - 50 kg/cm
Typical price
64.– to 120.–Servos in this range provide significant torque, making them suitable for medium-sized RC vehicles and more complex robotics.
Perfect for users who need reliable performance for tasks like steering larger vehicles or controlling multiple jointed arms.
Bestseller
51 - 500 kg/cm
Typical price
17.– to 57.–This high torque category supports heavy-duty applications, such as industrial robots or large-scale RC models.
Recommended for advanced users requiring robust performance in demanding conditions, providing exceptional strength and precision.
Bestseller
Servo speed refers to the time it takes for a servo to move from one position to another, measured in seconds per 60 degrees of rotation. Choosing the right speed is crucial for achieving the desired responsiveness and control in your RC applications, affecting how well your model performs.
Popular options
Up to 0.1 s
This option provides ultra-fast response times, allowing for quick adjustments and rapid movements.
Ideal for high-speed applications like racing drones or fast RC cars, where quick reflexes are essential for competitive performance.
Bestseller
0.11 - 0.15 s
Offers a balanced speed suitable for a variety of applications, ensuring both agility and control.
Recommended for general RC vehicles and aircraft, providing a good mix of speed and precision for most users.
Bestseller
0.16 - 0.19 s
Features a slower response time, which can be beneficial for applications requiring more stability and control.
Best for larger models or those that prioritize smooth operation over speed, such as cameras on drones or scale models.
