Gator RC Futaba Style 25T 50mm (1.97") Aluminum Locking Servo Arm

The Gator RC Aluminum Locking Servo Arm is designed for Futaba-style 25T spline servos and provides a strong, rigid, and precise linkage solution for RC aircraft applications. Built from CNC-machined anodized aluminum, this servo arm is ideal for larger RC airplanes and high-load control surface setups where reduced flex and accurate control response are important.

The locking clamp design helps provide a secure connection to the servo spline for dependable operation during demanding flight conditions.

✅ Ideal Applications:

  • RC airplanes
  • Aerobatic aircraft
  • Giant-scale airplanes
  • Sport aircraft
  • Jets and high-performance RC models
⚠ Spline Compatibility Note: This servo arm fits many popular Futaba-style 25T spline servos, including compatible models from Futaba, Savox, KingMax, MKS, and HobbyKing. Always verify spline count before ordering, as spline compatibility varies between servo manufacturers.

Key Features

  • High-Load Sizing: Generous 50mm (1.97") total overall length with a 38mm (1.50") linkage hole-to-hole specification.
  • Rigid CNC Milling: High-strength anodized aluminum build eliminates flex over plastic horns, stabilizing larger RC airplane control systems.
  • Secure Spline Lock: Locking clamp-style spline connection distributes clamping load evenly around the output hub.
  • Heavy-Duty Threading: Pre-tapped cleanly for M3 threaded linkage hardware to withstand high structural flight torque.
  • Vibrant Finishes: Light but incredibly stiff 3.5g architecture available in Red, Black, Gold, and Platinum colorways.

✈ Why Use an Aluminum Locking Servo Arm?

Aluminum servo arms help improve control precision by reducing flex in the linkage system compared to standard plastic servo horns. This is especially useful for larger RC airplanes, aerobatic aircraft, and higher-load control surface applications.

The locking clamp design helps maintain a more secure spline connection during aggressive flight maneuvers and vibration-heavy applications.

📦 Package Includes:

  • 1x Gator RC Futaba Style 25T 50mm (1.97") Aluminum Locking Servo Arm
  • Clamping Screw Hardware

💡 Installation Tips

  • Use thread lock compound on all metal-to-metal hardware.
  • Do not overtighten screws to avoid thread damage.
  • Verify linkage geometry and servo travel before flight to ensure no binding occurs.
  • Ensure the servo arm is fully seated down on the spline before tightening the lock.
  • Inspect linkage hardware regularly to preserve maximum flying safety boundaries.

The Gator-RC Advantage: We manage our manufacturing tolerances tightly so that our clamp-locking solutions close seamlessly across 25T splines, isolating your servo gears from heavy flutter and vibration wear.
