The discontinued Expert SL680 is a powerful, high-torque digital servo in a standard size, known for delivering immense strength with the quality and reliability of the Expert brand. This servo is engineered for the most demanding applications where holding power and brute force are essential. The SL680 is a top choice for the steering on a heavy 1/8 scale monster truck or a competitive rock crawler, where its massive torque can handle the heaviest wheels and the most challenging terrain. It is also an excellent choice for the rudder on a giant-scale 3D aircraft, where it has the authority to handle extreme aerodynamic loads with ease.
The identity of the SL680 is its intelligent power. The advanced digital controller provides ferocious holding power, actively fighting against external forces to keep the control surface or wheels exactly where they are commanded. This provides a feeling of absolute, unwavering control and stability. The high-quality motor and heavy-duty gear train ensure that this massive power is delivered reliably, upholding the Expert brand's reputation for durability.
In the field of heavy-duty robotics, the Expert SL680 is a formidable tool. Its immense digital torque makes it perfect for the primary lifting joints of a large industrial robot, a powerful hydraulic valve actuator, or the leg joints of a very large, heavy walking robot. It is an actuator for mission-critical applications where both extreme power and high reliability are required."
