The Graupner DES 488 BBMG is a powerful, high-torque digital sub-micro servo from the esteemed DES line. This servo is a true powerhouse, featuring a precise digital controller, a heavy-duty all-Metal Gear (MG) train, and a durable dual Ball Bearing (BB) supported output shaft. The DES 488 BBMG is designed for high-stress applications where strength is the most critical factor. It is an outstanding choice for the flight controls on an overpowered 3D park flyer with large control surfaces, or as an incredibly strong cyclic servo for a 450-class helicopter set up for maximum performance.
The identity of the DES 488 BBMG is its potent, precise strength. It delivers a level of torque that is truly astonishing for its size, giving the pilot a feeling of absolute, unwavering control authority. The digital controller provides immense holding power, and the robust MBB gear train ensures that this power is delivered reliably and without slop. It is a servo for the expert pilot who is pushing the limits and needs the strongest, most reliable sub-micro servo available.
For roboticists, the Graupner DES 488 BBMG's incredible torque-to-size ratio makes it a powerful problem-solver. It is ideal for building a small but incredibly strong robotic gripper, a powerful micro-sized lifting mechanism, or for the leg joints of a dynamic walking robot that needs to jump or carry heavy equipment. When a compact project requires an almost absurd amount of force, the DES 488 BBMG delivers.
