HV777A+ (0.10s/60°, 40.4kg.cm)

Very high torque/high speed programmable digital standard servo with metal gears and twin ballraced output shaft; for general use, large model aeroplanes. An aluminium case for perfect cooling even under high 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.
Left Angle: Max. Left angle adjustment.
Right Angle: Max. Right angle adjustment.
Reversion: Reverse of the PWM command.
Allow Uncont: The Servo move to the “Uncontrolled Position” when the PWM command is loss.
Uncontrolled Pos: The emergency position in the case of PWM command loss, if the “Allow Uncont” is turned on.
Uncontrolled Time: The Servo will move to the “Uncontrolled Pos” after the “Uncontrolled Time” when the PWM command is loss.
