Gator RC Black 25T Futaba Style 31mm (1.22") Aluminum Locking Servo Arm
The Gator RC Black Aluminum Locking Servo Arm is designed for Futaba-style 25T spline servos and provides a rigid, secure, and precise linkage solution for RC aircraft applications. Built from CNC-machined anodized aluminum, this servo arm is ideal for pilots looking for improved control precision and reduced linkage flex compared to standard plastic servo horns.
The single-arm pinch-clamp locking design helps provide a secure fit to the servo spline while maintaining smooth and accurate control surface movement for high-performance RC airplanes.
✅ Ideal Applications:
- RC airplanes
- Aerobatic aircraft
- Giant-scale airplanes
- Sport aircraft
- Jets and high-performance RC models
📏 Linkage Position Information:
- 15mm (0.59") position: Provides increased servo resolution and smoother control feel.
- 19mm (0.75") position: Increases control throw and surface movement.
Key Features
- Ultra-Lightweight Precision: Sized at 31mm (1.22") overall length and optimized to weigh a mere 1.7g (0.06 oz.).
- Dual-Throw Layout: Features 15mm (0.59") and 19mm (0.75") linkage mounting positions built for clear M2 linkage screw compatibility.
- Pinch-Clamp Lock: Single-arm clamp-style blueprint employs a secure pinch-clamp locking mechanism for absolute spine mating integrity.
- Premium CNC Detail: Machine-milled from top-tier aluminum with a black anodized casing highlighted by raw silver machined edge details.
- Structural Rigidity: Clean unibody profiles dramatically reduce link flex, ensuring crisp handling responses under steep aerodynamic loading.

✈ Why Use a Locking Aluminum Servo Arm?
Aluminum locking servo arms help improve control precision by reducing flex in the linkage system while also providing a stronger connection between the servo spline and linkage hardware.
The pinch-clamp locking system helps provide a more secure spline connection compared to traditional set-screw servo arms, making this style especially popular for aerobatic aircraft, giant-scale airplanes, jets, and other high-performance RC applications.

💡 Installation Tips & Guide
- Use thread lock compound on all metal-to-metal hardware.
- Verify linkage geometry and servo travel before flight to completely avoid binding scenarios.
- Ensure the servo arm is fully seated down onto the spline before engaging the side clamp screw.
- Do not overtighten the clamp screw.
- Inspect your control linkage assembly hardware regularly for continuous flight line safety.
The Gator-RC Advantage: We design our single-arm clamp line with tight physical profiling parameters to ensure uniform circumferential pressure around 25T output splines, reducing point wear and optimizing control transfer accuracy.
