Notes
- The discontinued Blue Bird BMS-303 is a classic pico-class analog servo that serves as a fundamental building block for the world of ultra-lightweight flight. Weighing only a few grams, it is designed for the lightest of indoor models, small "living room flyers," and park flyers where minimizing all-up weight is the single most important design goal. Its purpose is to provide reliable, proportional control with the smallest possible penalty in mass and current draw. The BMS-303 is a simple, no-frills actuator that has earned a reputation for its dependable performance in countless scratch-built and kit-built micro aircraft. It is often the first servo a builder uses when venturing into the delicate art of constructing models that seem to defy gravity.
- The value of the BMS-303 lies in its elegant simplicity and efficiency. It does its job without complexity, providing smooth and adequate control for the gentle flight envelopes of typical indoor and micro models. For hobbyists who enjoy the challenge and reward of building and flying the lightest possible aircraft, the BMS-303 is an essential component. Its affordability and reliability have made it a staple in the workshops of micro-flight enthusiasts around the world.
- For robotics students and hobbyists, the BMS-303 is an excellent and highly accessible tool for experimenting with micro-mechatronics. Its extremely small size and low weight allow it to be incorporated into the most delicate of projects. It is ideal for animating miniature figures, actuating the control surfaces on a micro-sized ornithopter, or providing movement in a tiny, insect-inspired robot. When a project's success hinges on shedding every possible gram, the BMS-303 is a foundational component.
