The GWS Fast Naro is a specialized version of the legendary Naro sub-micro servo, specifically tuned for high speed. While retaining the same compact 8-9 gram size, its internal gear ratio is optimized to provide a much quicker transit time, making it a favorite for applications where agility is key. The Fast Naro is an outstanding, budget-friendly choice for the ailerons on a fast-moving park jet or flying wing, where it can deliver a very high roll rate. It is also a popular option for the tail rotor on small helicopters, where its speed allows the gyro to make rapid corrections, leading to a more stable and responsive tail.
The defining characteristic of the Fast Naro is the nimble, reactive feel it imparts to a model. It is a servo for the pilot who enjoys dynamic, high-energy flying and wants a control system that can keep up with their rapid stick movements. It's a simple, cost-effective upgrade that can dramatically change the character of an aircraft, making it feel more exciting and aerobatic.
For roboticists, the GWS Fast Naro's speed is a valuable asset in a compact package. It is an excellent actuator for any small project that requires a quick, repetitive motion, such as a lightweight sorting gate, a rapid-fire triggering mechanism on a small competitive robot, or a high-speed sensor-scanning turret. It offers a specialized, high-velocity performance at the classic GWS value price point.
