Kavan GO-12S70MG 69g High-Torque Programmable Digital Standard Servo w/ Coreless Motor & Steel Gears

Overview

The KAVAN GO-12S70MG (KAV20.12S70MG) is a powerful and extremely fast 69 g programmable digital standard servo with a coreless motor, hardened steel gears, dual ball bearings, and a wide voltage range of 4.8–8.4 V. It delivers up to 20.5 kg·cm of torque at 8.4 V with an impressive speed of 0.06 s/60°. The aluminum center heatsink provides effective heat dissipation under high loads. Ideal for 1:10 on-road RC cars, aircraft, helicopters, and other models requiring high power and fast response.

Programmable functions

• Servo angle: Sets the maximum range of the servo's rotation angle. The standard range is approximately 120° within the normal RC signal pulse-width range (900~2100 µs); approximately 180° within the maximum signal pulse-width range (500~2500 µs).
• Servo neutral: Sets the neutral (center) position of the servo.
• Damping factor: Sets the servo damping—adjusts the servo characteristics when stationary.
• PWM power: Adjusts the servo's output power. The higher the power, the higher the servo's speed and torque—and the higher the power consumption.
• Sensitivity: Sets the servo sensitivity (deadband). The higher the sensitivity, the narrower the deadband—the servo moves only when the change in signal pulse width is greater than the deadband. A setting that is too high may cause servo oscillation in some applications. Range: Ultra high (approx. 1 µs deadband) – High (approx. 2 µs) – Medium (approx. 3 µs) – Low (approx. 4 µs)
• Soft Start: Enables/disables the soft-start function. When enabled, the servo moves slowly to the initial position corresponding to the servo signal as soon as power is switched on.
• Reverse: Reverses the servo's direction of movement.
• Narrowband: FUTABA SR mode—only to be used with FUTABA radio channels operating in SR mode. Do not enable this option when using a different setting on your FUTABA radio or using another radio.
• SANWA SSR: SANWA SSR mode—only to be used with SANWA radio channels operating in SSR mode. Do not enable this option when using a different setting on your SANWA radio or using another radio.
• PPM loss protection (fail-safe): If the receiver's control signal is completely lost or cannot be decoded correctly (due to interference), the servo can select one of three fail-safe modes:
  • (a) Release: No fail-safe protection.
  • (b) Hold position: Maintains the position corresponding to the last correctly received control signal.
  • (c) Return to neutral position: The servo returns to the neutral position (1500 µs pulse width).
• Overload protection: Enables or disables the servo's overload protection at three levels. Once the overload persists for the set time (in seconds), the servo's output power is reduced to the corresponding set level (% of maximum power).
• Default: Restores the factory settings of the connected servo.
