Notes
- The discontinued GWS S677-2BB/MG is a powerful, high-torque servo that is packed with premium features, including a rugged all-Metal Gear (MG) train and a precise Dual Ball Bearing (2BB) supported output shaft. This standard-sized servo is designed for demanding applications that require both significant strength and high durability. It is an outstanding choice for the steering on a 1/8 scale off-road buggy, where it has the power to handle the terrain, the durability to survive the race, and the precision to hit every apex. It is also an excellent, robust servo for the flight controls on a large, high-performance aerobatic aircraft.
- The essence of the S677-2BB/MG is its complete, high-quality feature set, offered at a competitive price point. It is a servo that makes no compromises, delivering a powerful and authoritative control feel that is also exceptionally smooth and slop-free. The metal gears provide the toughness, the ball bearings provide the precision, and the powerful motor provides the strength. This makes it a favorite among experienced hobbyists who want a single, high-quality servo type that can excel in a variety of demanding roles.
- For robotics engineers, the S677-2BB/MG is a premium, versatile actuator. It is tough enough for a competitive combat robot, yet precise enough for a sophisticated robotic manipulator. Its combination of features makes it a very reliable and capable component for any project where the actuator will be subjected to both high loads and the need for accurate positioning. It is a high-quality building block for creating truly robust and capable robots."
