Kavan GO-1021MG 10.4kg.cm, 0.055s/60° Programmable Digital HV Micro Servo w/ Steel Gears

Overview

The KAVAN GO Micro Servo is a powerful 21g digital micro servo with steel gears, dual ball bearings, and an operating voltage of 4.8–8.4V. With torque of up to 10.4 kg·cm and a speed of up to 0.055 s/60°, it is ideal for ailerons and flaps of gliders and hotliners. The slim 12mm aluminum housing provides excellent cooling and is suitable for thin wing profiles. Programmable via the KAVAN GO USB programming interface and PC software.

Features

• Servo angle: Sets the maximum travel of the servo. The default setting is approximately 120° with a normal control pulse width (900~2100 µs); approximately 180° with the maximum permitted control pulse width (500~2500 µs).
• Servo neutral: Sets the neutral (center) position of the servo.
• Damping factor: Sets the servo's stopping characteristics.
• PWM power: Sets the servo's output power. The higher the value, the faster the servo moves and the greater its thrust—of course, current consumption will increase proportionally. Range: 39.2~100%
• Sensitivity: Adjusts the servo's sensitivity (deadband). The higher the value, the narrower the deadband—the servo moves only when the change in control signal width is greater than the deadband. A sensitivity setting that is too high may cause servo oscillation in some applications. Range: Ultra High (Extra High—sensitivity deadband approx. 1 µs) - High (High—approx. 2 µs) - Medium (Medium—approx. 3 µs) - Low (Low—approx. 4 µs)
• Soft start: Enables/disables the soft-start function. This function prevents the servo from moving abruptly to the operating position when power is switched on, reducing the risk of damage to the servo gears.
• Reverse: Reverses the servo's direction of rotation.
• FUTABA SR mode: For use only with a FUTABA RC system in SR mode. Do not enable this option if you are using another FUTABA RC system setting or an RC system from another brand.
• SANWA SSR mode: For use only with a SANWA RC system in SSR mode. Do not enable this option if you are using another SANWA RC system setting or an RC system from another brand.
• Fail-safe: If the receiver's control signal is completely lost or the servo cannot detect the signal correctly (e.g., due to interference), the servo can enter one of three fail-safe modes:
  • (a) Free: Fail-safe is disabled.
  • (b) Hold position: The servo maintains the position corresponding to the last correctly received signal.
  • (c) Return to neutral: The servo returns to the neutral position (pulse width of 1500 µs).
• Overload protection: Enables or disables the servo's overload protection at three levels. Once the overload has lasted for a preset time (in seconds), the servo's output power is limited to the corresponding preset value (% of maximum power).
• Reset: Returns the connected servo to its factory settings.
