An RC servo is a device that translates electrical signals from the receiver into mechanical movement. Servos are used in RC vehicles to control the movement of various components, such as steering and throttle.
There are several different types of RC servos, including:
Standard Servos: These are the most common type of RC servo and are used in a variety of applications. They typically have a torque rating between 3 and 20 kg-cm and a speed of 0.1 to 0.2 seconds per 60 degrees of rotation.
High-Torque Servos: These servos have a higher torque rating than standard servos, typically between 20 and 30 kg-cm. They are used in applications that require more power, such as steering on larger RC vehicles.
Low-Profile Servos: These servos are designed to be smaller and flatter than standard servos, making them ideal for use in applications where space is limited.
Digital Servos: These servos use a digital signal to provide more precise and accurate movement than analog servos. They are also typically faster and have a higher torque rating than analog servos.
Waterproof Servos: These servos are designed to be water-resistant or waterproof, making them ideal for use in wet or damp environments.
Metal Gear Servos: These servos have metal gears, which make them more durable and able to handle higher torque loads than plastic gear servos.
When choosing an RC servo, it's important to consider the specific application and requirements of your RC vehicle. Factors such as torque rating, speed, size, and durability should all be taken into account. By selecting a servo that is appropriate for your vehicle and intended use, you can ensure optimal performance and reliability.
