Notes
- The discontinued Blue Bird BMS-885DMAX is a high-voltage (HV), high-performance digital servo that brings "MAX" performance to the sub-micro category. It is engineered to provide a fantastic blend of high speed and high torque, making it a versatile and powerful upgrade for a wide range of aircraft. It features a precise digital (D) controller and likely a powerful coreless motor to achieve its "MAX" performance rating. This makes it a great all-around choice for demanding applications like the cyclic controls on 450-class helicopters, the control surfaces on fast park jets, or as a robust steering servo for 1/16 scale trucks. The HV capability allows it to unleash its full potential when powered by a 2S LiPo.
- The BMS-885DMAX is characterized by its excellent and potent all-around performance. It finds the sweet spot between being incredibly fast and incredibly strong, making it adaptable to many different high-performance roles. The digital controller provides the locked-in, precise feel that modern pilots expect, while the high-performance motor delivers the speed and power needed for aggressive flying. It's a servo that provides a significant and noticeable performance boost over standard servos, making any model it's installed in feel more responsive and capable.
- For robotics hobbyists, the BMS-885DMAX is a very attractive option. Its high-voltage capability, compact size, and great all-around performance make it a powerful building block for many different projects. It's strong and fast enough for the limbs of a dynamic walking robot, the actuators of a quick-moving robotic arm, or the steering system on a fast autonomous car. It offers a huge amount of performance in a small package, enabling more ambitious and capable robotic designs.
