Notes
- The Blue Bird BMS-621MG is a top-tier analog servo that combines the trifecta of high-performance features in a standard-size package: a fast coreless motor, a precise dual ball-bearing supported output shaft, and a rugged all-metal gear (MG) train. This creates a servo that is fast, precise, and incredibly tough. It is designed for the most demanding sport and competition applications where all aspects of performance are critical. It is a premier choice for the steering on a competitive 1/8 scale race buggy, the cyclic controls on a 600-class 3D helicopter, or the control surfaces on a giant-scale aerobatic plane flown with aggression.
- The BMS-621MG is the quintessential high-performance analog workhorse. It delivers the speed and smooth response of a coreless motor, the slop-free precision of dual ball bearings, and the peace of mind of a bulletproof metal gear set. It gives pilots and drivers the confidence to push their equipment to the absolute limit, knowing that their control system is more than up to the task. It is a servo that can withstand extreme loads, high G-forces, and jarring impacts without any degradation in its exceptional performance.
- In the world of high-performance robotics, the BMS-621MG is a powerful and versatile tool. Its combination of speed, precision, and toughness makes it suitable for a vast range of applications. It would be an excellent actuator for the joints of a large, dynamic walking robot, where it needs to be both fast and able to withstand the shock of each footstep. It is also a great choice for a high-speed, high-power robotic manipulator in an industrial setting, where it would provide years of reliable service even in a demanding, high-cycle environment.
