actionarticle

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.
- High voltage, operating voltage up to 8.4 V!
- Direct operation with 2-cell LiPo batteries
- Operating voltage range 4.8 ... 8.4 V
- 2 x ball bearings
- Metal gearbox

Info
High-Voltage Servo (HVS) High-voltage, 2-cell LiPo batteries provide a direct power supply. This is the new product range from the digital servo segment, HVS (high-voltage servo).
With a maximum permissible operating voltage of 8.4 V, the new battery technology can be used without reservation. Naturally, these servos can also be operated with a conventional 6.0 V supply. The very best production quality tops off this line of our servos.
