DES 488 BB MG Digital Servo

Especially suitable for motor and glider models as well as micro-helicopters.


With this servo with metal gear the potentiometer operating voltage is transmitted to the metal axis of the servo. The use of aluminium control horns or a non-insulated RDS linkage with a conductive connection, e.g. in a full carbon fibre model, causes mutual interference between the servos, as the above-mentioned voltage is transmitted. Therefore please use either plastic control surface horns or insulate the mountings so that there is no electrical connection.

The Graupner/SJ GmbH company as manufacturer recommends that you use only components and accessories which have been tested for suitability and safety by Graupner/SJ and which have been approved for use. In this case Graupner/SJ will assume product responsibility for you. Graupner/SJ accepts no liability for non-approved parts or accessory products from other manufacturers and cannot evaluate every single third-party product. Whether it can be used without safety risk.

Graupner servos represent a product line which provides the right servo for almost every application with a wide range of specifications. Different sizes, gear designs, actuating forces and actuating times designed for the beginner to the competition pilot.
