The discontinued Graupner C 12021 is a high-performance analog servo in a compact, sub-micro package, known for its exceptional speed and precision. This servo often features a high-quality coreless motor, which provides a much faster and smoother response than conventional motors. The C 12021 is a specialized tool for demanding applications, making it a premier choice for tail rotor control on 450-class helicopters, where its speed is critical for a locked-in tail. It is also an outstanding servo for the flight controls on a fast park jet or a competitive pylon racer.
The essence of the C 12021 is its refined, high-speed performance. The coreless motor allows it to accelerate and change direction almost instantly, resulting in a very direct, high-fidelity control feel. This allows pilots to fly with a greater degree of aggression and precision. It is a competition-grade component designed to give the user a tangible performance advantage in any discipline where speed is king.
For roboticists working on high-speed, compact projects, the Graupner C 12021 is a superb actuator. Its coreless motor's rapid response is ideal for building a fast and accurate micro-robotic manipulator or a high-speed tracking system. For any project where the performance is limited by the speed and responsiveness of its actuators, the C 12021 offers a professional-grade solution.
