Notes
- The discontinued Cirrus CS-4.9 is a high-performance analog pico-class servo that pushes the boundaries of what is possible in an ultra-lightweight package. Weighing just under 5 grams, it is designed for high-performance micro applications where both low weight and a strong, positive control feel are required. It is a very popular choice for the flight controls of high-performance "shock flyers," micro 3D models, and as a high-quality cyclic servo for micro helicopters. The CS-4.9 is known for delivering a surprising amount of speed and torque for its size, giving pilots a crisp, authoritative control response that is not always found in the pico class.
- The character of the CS-4.9 is defined by its "big performance in a small package" nature. It's a servo that feels more powerful than its weight would suggest. This gives pilots the confidence to fly more aggressively, knowing their servos can handle the loads of demanding maneuvers. It provides a more connected and precise feel than lighter-weight pico servos, making it a favorite upgrade for pilots looking to enhance the performance of their favorite micro aircraft.
- In the world of advanced micro-robotics, the CS-4.9 is a very capable actuator. Its higher power output makes it suitable for more demanding tasks than its lighter siblings. It is an excellent choice for building a micro-sized robotic gripper that can actually grasp objects with some force, or for the leg joints of a slightly larger or heavier micro-robot. When a compact project needs a little extra muscle without a big weight penalty, the CS-4.9 is a perfect fit.
