Servo DES 478 BB, MG Graupner 7917

Servo digital DES 478 BB MG 12 mm Graupner 7917 DES servos (digital eco servos)
A new series of products to complement our existing range of digital servos.
These DES servos represent a product line which includes a suitable servo for every type of application, covering a vast range of specifications: different case sizes, gearbox types, torque levels and transit speeds, designed for any modeller from the beginner to the competition pilot.
The range includes some fully sealed versions (case screws, case sections and output gear) for increased operational reliability of your models.
Servos with precision-made twin-ballraced gearboxes made of aluminium and other metals guarantee superbly accurate positional performance. High-quality Amtel micro-controllers are used to process the control signals and provide good positional accuracy.
For RC power models, gliders and micro-helicopters
Do not use in carbon wings with RDS with electrical connection or aluminium levers. The gear/RDS or the aluminium levers must be electrically isolated! Potentiometer voltage is present on the gear.

• Ball bearings
• Metal gearbox
