More info

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.
Suitable for RC model aircraft, helicopters, RC cars and model boats.

  • The new, optimised digital successor to the familiar standard servo C577
  • Dimensions of the mounts in relation to drive mechanism are the same as for servo C577, so changing is easy
  • Ball bearings
  • Carbonite gear
  • Cannot be programmed via PC servo software
