Notes
- The discontinued Blue Bird BMS-303DMG represents the ultimate evolution of the pico-class servo, combining the very best technologies into a single, powerhouse package: a precise digital (D) controller, a powerful motor, and a rugged metal gear (MG) train. This servo is engineered for the most demanding and punishing micro-applications imaginable, where both high performance and extreme durability are required. It is the definitive choice for the cyclic controls on high-performance, "smack" 3D micro helicopters, or for the control surfaces on an overpowered, aggressive micro-sized flying wing or pylon racer. In these scenarios, the servo must endure intense vibration, high G-forces, and the potential for high-impact crashes, making the resilience of the metal gears an absolute necessity.
- This servo is the embodiment of performance without compromise in the pico class. The digital controller provides the speed and precision needed for lightning-fast 3D maneuvers, while the metal gears provide the assurance that the control system will not fail under the immense stress. This gives pilots the ultimate confidence to push the boundaries of micro flight, attempting maneuvers that would strip the gears of a lesser servo. It is a premium component for pilots who demand the absolute best and are unwilling to accept any weak links in their setup.
- In the challenging world of micro-robotics, particularly combat robotics in the "antweight" (1lb) or "fleaweight" classes, the BMS-303DMG is a formidable weapon. Its combination of speed, power, and near-indestructible gears makes it a perfect actuator for powerful lifting arms, devastating flippers, or robust drive systems that can survive the brutal reality of the combat arena. It’s the servo to choose when a micro project must be both agile and invincible.
