Product information

A powerful digital precision servo
with twin ballraces on the output shaft, and robust,
big modulus plastic gears for zero slop. The improved
successor to the proven DS 8201 digital
servo. For high-performance models and helicopters,
where maximum positional accuracy, freedom
from lost motion and extreme power are required.
   

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
