Very high torque/high speed programmable digital standard 83g brushless servo with hardened steel gear and triple BB-ed output shaft. Works great in large/giant planes, helicopters, 1:8 or 1:10 RC cars etc. All-aluminium case for perfect cooling under high load.

GO-1081MG is programmable using the KAVAN GO servo USB programmer/interface and PC software.

Programmable Functions
Servo Angle: Maximal servo rotation angle range setting. The default range is ca 120° within the regular RC signal pulse width range (900~2100 µs); ca 180° within the max. signal pulse width range (500~2500 µs).
Servo Neutral: Servo neutral (centre) position setting.
Damping Factor: Servo damping setting – adjust the characteristics of the servo when stopping.
PWM Power: Adjusts the servo output power. The higher the power, the higher the speed and torque of the servo – indeed also the current consumption will be higher.
Sensitivity: Servo sensitivity (Dead Band) setting. The higher sensitivity the narrower the dead band – servo moves only if the change of the signal pulse width is bigger than the dead band width. Too high setting may cause servo jitter in some applications. Range: Ultra High (ca 1 µs dead band) – High (ca 2 µs) – Medium (ca 3 µs) – Low (ca 4 µs)
Soft Start: Turns on/off the soft start feature. If ON, the servo goes slowly to the initial position corresponding to the servo signal once the power is switched on.
Reverse: Reverses the servo movement direction.
Narrow Band: FUTABA SR Mode – only for use with FUTABA radio channels working in the SR mode. Do not turn the option on if you are using a different setting of your FUTABA radio or any other radio. SANWA SSR: SANWA SSR Mode - only for use with SANWA radio channels working in the SSR mode. Do not turn the option on if you are using a different setting of your SANWA radio or any other radio.
Lost PPM Protection (Fail-Safe): In the case the control signal from the receiver is lost completely or cannot be decoded correctly (due to interference) the servo can use choose one of three fail-safe modes:
(a) Release: No fail-safe protection.
(b) Keep Position: Keeps the position corresponding to the last correct control signal.
(c) Go Neutral Position: The servo returns to the neutral (1500 µs pulse width) position.
Over Load protection: Enables or disables overload protection of the servo in three levels – once the overload conditions last for the pre-set time (in seconds), the output power of the servo is reduced to the corresponding pre-set level (% of the max. power).
Default: Restores the factory default setting of the connected servo.
Wide input voltage range 4.8-7.4 V (nominal).
25T/5.92 mm output shaft.
