About RC Car Servos
From steering to throttle management, RC car servos are the unsung heroes of the radio control (RC) world. Their purpose is to provide precise control over various functions in RC vehicles like brake control, transmission shifting, etc., as they play pivotal roles in ensuring smooth operation and enhanced performance. Before you choose an RC car servo, you should know everything there is to know about them, from their types to features, maintenance tips and other pointers to steer you in the right direction. So, without further ado, here's your very own RC car servo guide.
What Are RC Car Servos?
An RC car servo is a small electromechanical device that converts electrical signals into precise mechanical motion. It consists of a motor, a set of gears, a control circuit, and an output shaft. The primary function of an RC car servo is to provide accurate positioning and motion control, which is essential for various RC car applications. Essentially, it is what enables the RC car to steer, accelerate, shift gears, and perform an array of other functions. So, it's quite critical that you only get the best one, which RC Visions has an extensive collection of.
Features of RC Car Servos
When selecting an RC car servo, there are several key features on should consider for the compatibility and optimum performance of your RC vehicle. These features include:
-
Torque
Measured in ounce-inches, torque is the servo’s power to move or hold a position. Heavier RC cars like buggies are more compatible with high-torque servos. This is because they're used in demanding applications like off-road racing. For example, truck servos require high torque to handle the increased load and provide precise control.
-
Speed
Torque speed refers to how quickly the servo can move from one position to another, and it is usually measured in seconds per 60 degrees. Faster servos give quicker responses, making them ideal for high-speed racing and precise control. So, if a quick response is what you need as a racer, a high-speed servo will transform your racing experience.
-
Gear Type
Servos are made of gears and these gears can be made of materials like plastic or metal. Metal gears offer more durability, as they can handle high torque. A popular manufacturing brand that makes robust metal gear servos is Reefs RC.
-
Motor Type
Servos can be powered by different motor types, from brushed to brushless and coreless motors. Brushless motors provide higher efficiency, faster response, and longer life compared to their brushed counterparts. Coreless motors, on the other hand, offer smooth operation and are often used in high-performance servos.
-
Operating Voltage
The operating voltage of a servo determines its compatibility with different power sources. Standard servos mostly operate between a voltage rating of 4.8V and 6.0V, while high-voltage servos can handle 7.4V or more. For the optimum performance of your RC vehicle, you should ensure your servo always matches your RC car’s power system.
-
Size and Weight
Servos come in various sizes and weights to fit different RC car models. It's essential to choose a servo size that fits within the designated space in your RC car. At RC Visions, you can find the following servo sizes:
-
Standard Size Servos
Standard-size servos are the most common type used in RC cars. They offer a good balance of power, speed, and size, making them suitable for most 1/10 and 1/8-scale RC cars. These servos typically have metal gears for durability and can handle a wide range of operating voltages. -
Large Scale Servos
Large-scale servos are designed for bigger RC cars, such as 1/5-scale models. These servos provide higher torque and are built to handle the increased demands of larger vehicles. They often feature robust materials, such as metal gears and dual ball bearings, to ensure longevity and performance. -
Micro and Sub-Micro Servos
Micro and sub-micro servos are used in smaller RC cars and lightweight applications. Despite their small size, they can deliver impressive performance. These servos are ideal for compact spaces where standard servos would be too large.
-
Waterproof Servo
Waterproof servos are designed to withstand exposure to water and moisture, making them ideal for off-road and all-weather RC cars. Waterproofing your servo ensures it remains functional even in harsh terrains and conditions.
