Notes
- The discontinued Cirrus CS-90 is a large, powerful quarter-scale analog servo, designed to handle the significant loads of giant-scale aircraft and large surface vehicles. This servo provides the immense torque needed to operate the huge control surfaces (ailerons, elevator, rudder) found on 25% scale and larger airplanes. It is also a very popular choice for the steering systems on 1/5 and 1/4 scale gas-powered cars, buggies, and trucks. The CS-90 is built with a heavy-duty gear train and a potent motor, all housed in a robust case designed to withstand the stress and vibration of these massive applications.
- The identity of the CS-90 is its immense power and authority. It provides the brute force needed to move giant flight controls with precision or to steer a 30-pound RC car with ease. It gives the user a feeling of absolute security, knowing that their control system is more than capable of handling the extreme forces at play. For giant-scale hobbyists, where safety and reliability are paramount, the CS-90 has long been a trusted and cost-effective solution for getting the power they need.
- For builders of very large-scale robotics, the CS-90 is an essential component. Its massive torque makes it ideal for actuating the primary, load-bearing joints of a very large robot, a heavy-duty industrial-style gripper, or the steering system on a large autonomous vehicle that may weigh hundreds of pounds. When a project demands huge power from a conventional servo, the CS-90 delivers.
