Ultra high speed narrowband (760µs) digital standard brushless servo with metal gears and twin ballraced output shaft. Ideal for tail rotors of 600-800 class helicopters, compatible with most of 760µs gyro and flybarless systems. An aluminium case with CNC milled heatsink for perfect cooling even under extreme loads.

Input voltage range 6.0-7.4 V (nominal).

Using the DSP-2 MKS Digital Servo Programmer you can program a wide range of servo parameters:
Neutral: The setting of the neutral position.
Max_PWM (Max. pulse width): The maximum angular range will be limited within this command value.
Min_PWM (Min. pulse width): The minimum angular range will be limited within this command value.
Reverse: Reverse of the PWM command.
Dead_Band: The signal value can be allowed to change under the circumstance without affecting the angle of the output / servo arm.
CMD_Lost (Fail-Safe): The Servo move to the “CMD_Position” when the PWM control signal is lost.
CMD_Position: The emergency position in the case of PWM command lost, if the “ CMD_Lost ” is turned on.
CMD_Time: The Servo will move to the “CMD_Position” after the “CMD Time” when the PWM command is lost.
