The Graupner DES 658 BBMG is a top-tier digital servo that combines the trifecta of high-performance features in a standard-size package: a precise digital controller, a rugged all-Metal Gear (MG) train, and a slop-free dual Ball Bearing (BB) supported output shaft. This servo is a powerful and versatile workhorse, designed for demanding applications that require a combination of speed, torque, precision, and durability. It is an outstanding choice for the steering on a 1/8 scale off-road race buggy, or for the flight controls on a large, high-performance .60 to .90 size aerobatic aircraft.
The identity of the DES 658 BBMG is its "do-it-all" digital performance and reliability. It is a servo that can excel in a huge range of demanding roles, providing the speed for a quick response, the torque for authority, the precision for accuracy, and the durability to last. It is a favorite of experienced hobbyists who want a single, no-compromise servo type for their high-performance models. It is a true testament to the quality and engineering of the Graupner DES line.
In advanced robotics, the Graupner DES 658 BBMG is a superb, high-quality actuator. Its combination of digital precision, high power, and extreme durability makes it ideal for the primary joints of a sophisticated, dynamic walking robot or for a robust, high-payload robotic arm. It is a premium component for building robots that are designed to perform at a high level and to operate reliably for a very long time.
