Notes
- The discontinued Cirrus CS-650 is an immensely powerful, giant-scale analog servo designed to handle the most extreme loads in the RC hobby. This servo is a torque monster, engineered for the primary flight controls of large and giant-scale aircraft, typically in the 30% to 35% scale range. It is also a dominant choice for the steering systems on 1/5 and 1/4 scale gas-powered cars and trucks. The CS-650 features a very powerful motor and an extremely robust, heavy-duty gear train, all housed in a durable case designed to withstand the vibration and stress of these massive applications.
- The identity of the CS-650 is its sheer, uncompromising power. It produces a level of torque that can move the largest control surfaces or turn the heaviest wheels with absolute authority. For the pilot of a giant-scale aerobatic plane, this servo provides the rock-solid security and control needed to perform high-stress 3D maneuvers safely. For the driver of a 1/5 scale truck, it provides the power to steer the vehicle with precision, even in the most demanding off-road conditions. It is a servo chosen when a project's control system must be absolutely powerful and reliable.
- In the world of very large-scale robotics, the CS-650 is an essential component. Its massive torque makes it ideal for actuating the primary joints of a human-sized robot, a heavy-duty industrial gripper, or the steering system on a large, multi-hundred-pound autonomous vehicle. For any robotics project that needs to move very heavy loads with a conventional servo, the CS-650 provides the immense power required to get the job done.
