Kavan GO-11T82SHV 18kg.cm, 0.043s/60° High-Speed Digital HV Tail Servo

Overview

The KAVAN GO Brushless Tail Servo is an ultra-fast 83 g digital narrow-band servo (760 µs), specially developed for 500–800-class RC helicopters with advanced gyro or flybarless systems. Thanks to its brushless motor, titanium/hardened steel gears, triple ball bearings, and operating voltage of up to 14.4 V (3S LiPo), this servo delivers exceptional speed and precision. The fully aluminum housing ensures optimal cooling under heavy loads. Note: this 760 µs servo is suitable only for compatible gyro or flybarless systems and must not be connected directly to a standard receiver output.

Features

• Servo angle: Sets the maximum range of the servo's rotation angle.
• Servo neutral: Sets the servo's neutral (center) position.
• Damping factor: Sets the servo damping—adjusts the servo's characteristics when stationary.
• PWM power: Controls the servo's output power. The higher the power, the higher the servo's speed and torque—but also its 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.
• Soft start: Enables or disables the soft-start function. When enabled, the servo moves slowly to the initial position corresponding to the servo signal when power is switched on.
• Reverse: Reverses the servo's direction of movement.
• 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: Holds 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.
