Notes
- The Blue Bird BMS-136MG is a high-performance micro servo that brings the critical advantages of a digital controller and a rugged metal gear (MG) train to the highly competitive sub-10-gram weight class. This servo is engineered for discerning pilots of high-performance park flyers, small electric ducted fan (EDF) jets, and 250-class helicopters who require both precision and durability in a compact package. The digital controller provides a locked-in, responsive feel with excellent centering accuracy, which is vital for stable flight and crisp maneuvers. The key feature, however, is its metal gearset. In demanding applications like helicopter cyclic control or on the elevons of a fast-flying wing, the gear train is subjected to constant vibration and high loads. The BMS-136MG's metal gears provide a crucial layer of resilience, preventing the stripping and premature wear that can plague lesser plastic-geared servos.
- This servo is celebrated for its remarkable power and durability relative to its small size. It gives pilots the confidence to fly more aggressively, knowing their control system can handle the strain of high-G turns and the occasional rough landing. The combination of digital precision and metal gear toughness ensures that control remains slop-free and accurate over a long service life, making it a wise investment for any serious modeler.
- In the realm of robotics, the BMS-136MG is an outstanding choice for building small but robust mechanisms. It is perfectly suited for the joints of a small walking robot that needs to be both agile and durable. It would also excel in creating a powerful and resilient gripper for a small robotic arm, where the metal gears can withstand the stress of clamping onto objects and the digital controller provides precise force modulation. It's the go-to solution when a small-scale robotics project demands both intelligence and strength.
