Graupner,Servo DS 8418 Digital Ultra-S,5160

Servo DS 8418 Digital Ultra-S Graupner 5160 with highest possible transit speed, race-grade
metal gears, metal output shaft and twin ballraces,
for RC racing cars and high-speed models of all
kinds
Powerful ultra-fast digital servo with digital IC electronics,
more powerful MOS-FET bridged circuit,
matched lead about 180 mm long. This servo
meets the most exacting requirements and is on
the wish-list of the world´s top contest pilots.

GRAUPNER/JR digital servos have now been used
successfully all over the world, and the comprehensive
expertise built up by the JR company combined
with the development power of the Mitsubishi laboratories
have paved the way to further improvements
to the digital micro-processors used in these servos.
These digital servos feature re-designed micro-controllers
with their own intelligence, allowingthem to
check the control signals and calculate compensation
where necessary, e.g. for defective signals,
thermal drift and other parameters which can disturb
the servo. Super start-up torque in response to even the
tiniest deviation
More powerful MOS-FET bridged output stages
for improved maximum load
13-bit 5,900-step ACD system for ultra-precise
neutral setting and smooth movements at all times
Twin ballraced output shaft for minimum friction
and guaranteed accuracy
High pulse frequency ensures
high torque whilst protecting
the motor
