Super high torque/very high speed programmable digital standard brushless servo with metal gears and twin ballraced output shaft; ideal for 1/10, 1/8 and 1/5 RC buggies. An aluminium case with CNC milled heatsink for perfect cooling even under extreme loads.

Input voltage range 6.0-7.4 V (nominal), operational 6.0-8.4 V.

Using the DSP-1 USB Digital Servo Programmer/interface and the MKS PC software you can program a wide range of servo parameters:
Dead Band: The signal value can be allowed to change under the circumstance without affecting the angle of the output / servo arm. MKS Default 1µs or 1.2µs
Lock: The setting when the servo does not receive the signal - Keep at the last angular position / The motor is released.
Max. Duty: The duty cycle of the motor will be limited within this value.
Pulse Lower: The minimum angular range will be limited within this command value.
Neutral: The setting of the neutral position.
Pulse Upper: The maximum angular range will be limited within this command value.
Boost: The steps of the motor when starting-up. The larger the value is, the more powerful the step of the motor during the start-up.
