Gator RC F3A Servo Arm 37.25mm (1.47") Futaba 25T Aluminum – Red

The Gator RC F3A Servo Arm is a lightweight CNC machined aluminum servo arm designed for Futaba-style 25T spline servos. Built for precise control surface movement and reduced linkage flex, this servo arm is ideal for F3A pattern aircraft, aerobatic airplanes, and other precision RC applications.

The lightweight flat-profile design helps provide accurate linkage geometry while maintaining excellent rigidity compared to many standard plastic servo arms.

Why Use an Aluminum Servo Arm?

Aluminum servo arms help improve linkage precision and reduce flex compared to many standard plastic servo arms. This can improve control surface accuracy and provide more consistent servo response, especially in precision aerobatic and F3A aircraft.

The lightweight aluminum construction helps maintain precise linkage movement without adding unnecessary weight to the aircraft.

Ideal Applications

  • F3A pattern aircraft
  • Precision aerobatic airplanes
  • Sport RC airplanes
  • Lightweight aerobatic aircraft
  • Elevator linkages
  • Aileron linkages
  • Rudder linkages
  • Precision control setups

Installation Tips

  • Verify spline compatibility before installation
  • Use thread locker on metal-to-metal hardware
  • Check linkage geometry before flight
  • Do not overtighten mounting screws
  • Inspect linkage hardware regularly
