The Graupner DES 805 BB is another premier offering in the giant-scale DES digital servo line, likely offering a different balance of performance to its siblings. This servo is often tuned for a higher transit speed while still providing immense torque. It is an outstanding choice for applications on giant-scale aircraft where a faster response is desirable, such as the large ailerons on a 3D or aerobatic aircraft to achieve a higher roll rate, or for the rudder to enable crisp, fast snap maneuvers. It combines the raw power necessary for giant-scale flight with the speed needed for aggressive agility, all delivered with the precision of a digital controller and ball bearings.
The essence of the DES 805 BB is its agile, giant-scale performance. It allows pilots of very large aircraft to have a control system that feels nimble and responsive, not slow and heavy. This can completely transform the flying experience of a large 3D plane, making it feel much more reactive and capable. It is a servo for the advanced giant-scale pilot who demands both power and a high-speed, dynamic response from their control system.
For roboticists, the Graupner DES 805 BB's combination of size, speed, and precision is very valuable. It would be an excellent choice for the primary joints of a large but fast-moving robotic arm, or for any large-scale automation task where cycle time is a critical factor. It enables the creation of large robots that can move with surprising speed and agility.
