The discontinued Graupner C 5191 is a formidable, giant-scale servo, engineered to provide massive torque with the quality and reliability that the Graupner brand is known for. This servo is designed for the primary flight controls of the largest model aircraft, from 35% scale aerobatic planes to heavy, multi-engine scale models. The C 5191 is built with an extremely robust, heavy-duty gear train (often all-metal) and a very potent motor to handle the immense forces encountered in giant-scale flight. It is a servo that provides the ultimate in power and security for the most valuable and high-performance giant-scale aircraft.
The core identity of the C 5191 is its mission-critical, giant-scale power. For the pilot of a 100cc or larger aircraft, the integrity of the control system is the number one priority. The C 5191 is a servo that is trusted implicitly, known for its ability to deliver its massive torque smoothly and reliably, flight after flight. It provides the unwavering authority needed to fly these giant machines with precision and complete confidence.
For builders of the largest and most ambitious robotics projects, the Graupner C 5191 is an essential component. Its massive torque makes it ideal for the primary, load-bearing joints of a very large, human-sized robot, or for an industrial application that involves lifting or moving very heavy loads. It is a powerful and reliable actuator for the most challenging and large-scale robotic endeavors.
