Gator RC 1.18" (30mm) x 2.5mm Aluminum Servo Arm – JR / Spektrum 23T (Silver)
The Gator RC 1.18" (30mm) Aluminum Servo Arm is designed for JR and Spektrum servos using a 23T spline. Built from anodized aluminum, this servo arm provides excellent strength, rigidity, and precise control surface movement for RC aircraft applications.
One of the greatest benefits of aluminum servo arms is the reduced flex compared to many standard plastic servo horns. This helps improve linkage precision and control response, especially on larger or higher-load RC airplanes.
⚙️ Throw Positions (Drilled and Tapped):
This servo arm is drilled and tapped to accommodate the following linkage throw positions:
- 14mm (0.55")
- 19mm (0.75")
- 24mm (0.94")
- 30mm (1.18")
Key Features
- Rigid Control Geometry: 30mm (1.18") arm length tailored perfectly for reliable RC airplane control systems.
- Zero-Flex Build: Strong anodized aluminum construction with an attractive silver finish provides structural strength over flexible plastic horns.
- Tapped Linkage Holes: Threaded cleanly for 2.5mm hardware with multiple linkage mounting positions to support setup flexibility.
- Customizable Threading: Sturdy 2mm thickness allows the holes to be safely re-tapped for 4-40 or 3mm hardware if your layout requires it.
- Ultra-Light Footprint: Rigid, high-durability design weighs in at an incredibly light 3g (0.10 oz.).

✈ Why Use an Aluminum Servo Arm?
Aluminum servo arms help provide improved control precision by reducing flex in the linkage system. This can improve servo response and overall control feel on elevators, rudders, ailerons, throttle linkages, and other RC aircraft control surfaces.
The multiple mounting positions allow pilots to fine-tune control throw and linkage geometry based on aircraft setup and flying style.
📦 Package Includes:
- (1) Gator RC Aluminum Servo Arm
💡 Installation Guide & Tips
- Follow the aircraft manufacturer's recommendation for servo horn control setup.
- Use thread lock compound on all metal-to-metal mounting screws.
- Verify linkage geometry before flight and ensure the servo arm is fully seated on the spline.
- Inspect mounting hardware regularly to ensure flight-line safety.
The Gator-RC Advantage: We engineer our aluminum hardware lines to strictly preserve tight internal spline tolerances, giving pilots slop-free linkage geometry that holds up flight after flight.
