Notes
- The discontinued Caster Racing C3003 is a universally recognized, standard-sized analog servo that serves as a fundamental component in the RC hobby. It is the quintessential "standard servo," offering a reliable and highly cost-effective solution for a vast array of applications. It is most commonly found as an original equipment manufacturer (OEM) part in many ready-to-run (RTR) kits, handling steering duties on basic 1/10 scale on-road cars or throttle/brake functions on entry-level nitro vehicles. It provides adequate speed and power for general-purpose use, making it the perfect choice for beginners, casual hobbyists, or for non-critical applications like operating secondary features on a scale model.
- The identity of the C3003 is defined by its simplicity, ubiquity, and unbeatable value. It is a straightforward and dependable component that has been proven over decades of use in the hobby. For a person just getting into RC, or for a builder looking for a low-cost actuator for a simple project, the C3003 is the default choice. It is easy to install, easy to set up, and performs its job with a level of reliability that has made it a staple in workshops around the world. It is the benchmark against which other basic standard servos are often compared.
- In education and hobbyist robotics, the C3003 is an essential building block. Its low cost and standard dimensions make it the ideal actuator for introductory projects, classroom kits, and large-scale workshops where numerous servos are required. It is the perfect tool for teaching the fundamentals of mechatronics, and it is capable of handling a wide variety of simple robotic tasks, such as moving a sensor, operating a small gripper, or steering a lightweight robot. It is the starting point for countless robotics creations.
