GO-12S57MG (0.070s/60°, 20kg.cm)

High torque/very high speed standard low profile digital servo with a brushless motor and double BB-ed output shaft for general use in all kinds of RC models - great for 1:10/12 on-road RC cars, as well as model aeroplanes and helicopters. An aluminium case with a middle CNC-milled heatsink for perfect cooling under high load.

GO-12S57MG 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 the 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 a 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), operational 4.8–8.4 V.
