Servo HVS 976 BB Graupner 7981

Servo brushless HBS690 BB 16 mm Graupner 7981 Description
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.

Info
High-Voltage Brushless Servo (HBS) HBS (high-voltage brushless servo) combines the performance of brushless technology with all the advantages of high-voltage servos. In addition to the unparalleled acceleration, greater efficiency, and no wear of carbon brushes, these servos can be supplied with an operating voltage of up to 8.4V. Direct connection of 2-cell LiPo battery packs is now possible with no problem; in addition, these servos also provide top performance at an operating voltage of just 6V. Precision in manufacturing and assembly as well as the very best component quality make uncompromising power and speed available to the servo mechanism. A new dimension in the combination of power, speed, acceleration, precision, and resolution.
