KST FZ320 HV Low-EMF Mini Wing Servo 5.5Kgf.cm 0.09sec for RC Gliders & Jets

$78.99

Designed for weight-conscious RC glider and jet pilots who refuse to compromise on precision, the KST FZ320 high-voltage digital wing servo packs a coreless motor, all-metal gear train, and Low-EMF Anti-Interference Technology into an ultra-light 20g mini form factor. Whether you're trimming ailerons on an F3J sailplane or dialing flap authority on a high-speed jet, the FZ320 delivers smooth, repeatable response and robust holding torque — flight after flight.

Key Features

  • High-Voltage Operation: Native 6.0V–8.4V compatibility for direct 2S LiPo use, no regulator required.
  • Coreless DC Motor: Fast linear acceleration, minimal deadband, and consistent centering performance across the full travel range.
  • All-Metal Gear Train: Precision metal gears supported by dual ball bearings deliver zero-backlash control and reliable crash resistance.
  • Full CNC Aluminum Casing: Rigid, lightweight housing provides structural durability and efficient heat management.
  • Ultra-Lightweight Build: At just 20g, the FZ320 is optimized for weight-critical glider wings and compact jet installations.
