Ultimate Guide to RC Airplane Servos

RC airplane servos are an essential element of any model aircraft, responsible for the movement of control surfaces such as the ailerons, rudder, elevator, and flaps. They are the muscle of the RC airplane that makes it fly and maneuver in the air. Servos come in different types, sizes, and torque ratings. Some of the common sizes are micro, mini, and standard servos, and the torque rating determines how strong a servo is, measured in ounces per inch or kilograms per centimeter. When selecting an RC airplane servo, critical factors to consider are size, torque rating, and speed, which determine how quickly the servo can move and are proportional to the signal received from the transmitter.

Selecting the Right Servo for Your RC Airplane

When looking for RC airplane servos, it is essential to understand the size, torque rating and speed as these determine the servo’s compatibility with the particular airplane. There are different types of servos available in the market, and they come in various sizes and torque ratings. The size of a servo depends on the size of the RC airplane, with micro servos suitable for smaller planes and standard servos for larger aircraft. Torque rating determines the servo’s strength and the amount of force it can exert, which is essential for controlling the airplane’s movement in the air. Most servo manufacturers provide torque rating specifications that help in selecting a servo appropriate for the desired application.

Servos vary in speed, and their speed is typically measured in seconds per 60 degrees. High-speed servos provide rapid control surface movement, while slow servos offer slower, more controlled movements. Analog and digital are two types of servos available, with digital servo being more precise and expensive compared to analog servos. Digital servos come with higher resolution, high holding power, and faster response times, making them suitable for advanced RC pilots or aerobatic flying. Some recommended RC airplane servo brands are Hitec, Futaba, and Spektrum that provide high-quality and reliable servos.

An excellent way of comparing the different available servo sizes, torque ratings, and speed is by visiting various RC airplane and model shop websites.

Finding the Perfect Servo: A Guide to Choosing the Right Size, Torque, and Speed for Your RC Airplane

Servos are electronic devices that consume power to operate. Servos require a power source, which is usually the onboard flight battery, to receive signal translations to signal movement. If the battery is low, the servo’s response times will decrease, leading to reduced servo movement and airplane performance. Servos have limits on their movement range, determined by the servo horn’s structure and length and the control surface mechanical structure.

Control surfaces with larger deflections require stronger servos with high torque ratings. To get the best servo for your RC airplane, it is essential to visit specialty RC airplane shops or online RC model websites. However, selecting a high-quality servo does not come cheap, and prices vary depending on the servo’s specifications and features.

The table above provides an overview of the different servo sizes, torque ratings, speed, and price ranges for better selection. Micro servos have torque ratings ranging from 10-50 oz/in and speed ranging from 0.08-0.15 sec/60 deg. Mini servos have torque ratings ranging from 50-150 oz/in and speed ranging from 0.08-0.20 sec/60 deg. Standard servos have torque ratings ranging from 150-300+ oz/in and speed ranging from 0.15-0.25+ sec/60 deg.

It is important to select servo size, torque rating, and speed to ensure compatibility with your RC airplane. You can find high-quality servos from top brands like Futaba, Spektrum, and Hitec.

Choosing the Right Servo for Your RC Airplane

When it comes to RC airplane servos, there are several things to consider. One of the most important factors to consider is the speed of the servo. Servo speed is measured in seconds per 60 degrees rotation. High-speed servos are ideal for aerobatic flying and exceptional response times, while slower servos are suitable for trainers and general sport planes that do not require quick response times.

Another critical factor to consider when choosing RC airplane servos is the torque rating of the servo. Generally, lower speed servos typically have a higher torque rating.

It’s also important to note that faster servos may consume power more quickly. Additionally, digital servos generally have a higher response time and accuracy than analog servos. Although digital servos may have a higher cost, they offer additional features and benefits like higher resolution, stronger holding power, and improved accuracy.

When choosing a servo, it’s crucial to consider the type of airplane it will be used in and the type of flying that will be done with that plane. Several websites offer a selection of RC servo brands and models to choose from. HobbyKing, for instance, provides a wide range of servos ranging from tiny micro-servos for small RC planes to full-size standard servos suitable for larger airplanes. Additionally, websites like Amazon.com offer several leading servo brands like Futaba, Spektrum, Hitec, and many more. Thus, buyers have a wide range of options to choose from, depending on their budget and requirements.
