Notes
- The discontinued Cirrus CS-05 is a feather-light pico-class analog servo, representing one of the smallest and lightest actuators in the Cirrus lineup. It is meticulously designed for the growing world of indoor and micro R/C flight, where every fraction of a gram is critical to performance. The CS-05 is the quintessential choice for "living room flyers," small-scale foamies, and indoor duration models. Its incredibly low mass allows builders to create aircraft that seem to float on air, while its minimal current draw helps to maximize flight times from tiny single-cell LiPo batteries. It provides smooth, reliable proportional control for small rudders, elevators, and ailerons in the least demanding of flight envelopes.
- The value of the CS-05 lies in its extreme efficiency in terms of size and weight. It is a specialized tool for the dedicated micro-flight enthusiast who understands that success is measured in grams. Its simple and reliable analog performance is more than sufficient for the gentle speeds and low control surface loads encountered in indoor flying. It has a reputation as a dependable component that allows builders to push the boundaries of what is possible in ultra-lightweight aircraft construction.
- For roboticists and mechatronics experimenters, the CS-05 is a gateway to the fascinating world of micro-robotics. Its diminutive size and weight make it possible to actuate the tiniest of mechanisms. It is an ideal choice for building insect-inspired walking robots ("microwalkers"), animating the features of a miniature model, or creating the delicate control system for a flapping-wing ornithopter. When a project demands motion in the smallest possible package, the CS-05 is a fundamental building block.
