Understanding RC Heli Servos: Types, Technology and Maintenance
RC helicopter servos are an essential component for hobbyists who enjoy flying RC helicopters. Servos work as servomechanisms that drive the movement of the helicopter’s mechanical parts, such as the swashplate, tail rotor, and main rotor blades. Without servos, there would be no way to control the helicopter’s movements in the air. In this article, we will discuss the working principle of servos, the types of servos available, advancements in servo technology, and tips for choosing, maintaining, and troubleshooting servos, ensuring your helicopter has the power and precision it needs.
Choosing the Right RC Heli Servos
- First, let’s discuss how a servo works. A servo consists of three main components: a motor, gears, and electronics. The motor powers the gears, which amplify and transfer the motor’s power to the mechanical part it’s attached to. The electronics inside the servo control the motor’s speed and direction, which allows the servo to move precisely and accurately.
- Servos receive commands from the receiver, which processes input signals from the transmitter and sends them to the servos to execute.
- There are two types of servos: analog and digital. Digital servos offer more precision and accuracy than their analog counterparts and have faster response times.
- Newer servo models use brushless motors instead of brushed motors, increasing their efficiency and lifespan.
When choosing a servo for your RC helicopter, it’s important to consider the weight, size, and desired torque of the servo to match the requirements of your helicopter. Various websites offer a range of servos to choose from, with guides to help you select the right one. Additionally, it’s crucial to maintain and troubleshoot your servo regularly to ensure its longevity and proper functioning.
What factors should be considered when choosing a servo for an RC helicopter?
