Product information
Race-grade metal gears, twin ballraces and metal output shaft Specially developed for ultra high-speed models; the perfect choice when maximum possible transit speed and precision are required.
Fitted with a high-power coreless motor, digital IC electronics and a practical lead just 100 mm long.

New digital servos
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, allowing them 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.
