Notes
- The discontinued Blue Bird BMS-376DDG is a specialized, high-performance servo that stands out due to its unique combination of technologies, indicated by its "DDG" designation. This typically signifies a Digital (D), Direct Drive/Coreless (D) motor, and a specialized Gear (G) set, often composed of a hybrid of metal and durable composite materials. This servo is engineered for the ultimate in precision, speed, and low backlash. It is targeted at the most demanding competition pilots, particularly in helicopter flying (both swashplate and tail) and precision aerobatics, where any amount of gear slop or hesitation is unacceptable. The coreless motor provides instant response, while the high-precision gear train translates that motion with near-perfect fidelity.
- The essence of the BMS-376DDG is its pursuit of mechanical perfection. The goal is to create a servo with as close to zero backlash as possible, providing a truly one-to-one connection between the digital controller and the output shaft. This results in an incredibly crisp, precise, and slop-free feel that competitive pilots can exploit to achieve the highest levels of performance. It is a servo designed for those who can perceive and appreciate the subtle differences in control system response and who need the best possible equipment to compete at the highest level.
- In the realm of high-tech robotics and scientific instrumentation, the BMS-376DDG is a highly valuable component. Its extremely low backlash and high precision make it ideal for applications like laser beam steering, optical lens positioning, or as an actuator in a high-precision medical or scientific device. It would also be a superb choice for the joints of a research-grade robotic hand or manipulator where precise and repeatable positioning is a critical requirement for accomplishing delicate tasks. It's a servo for applications where precision is not just a feature, but the entire point.
