Secraft V1 1-Inch M2 Servo Arm – Futaba 25T, Red
The Secraft V1 1-Inch M2 Aluminum Servo Arm provides a strong, rigid connection between your servo and control linkage. CNC-machined from lightweight 6061-T6 aluminum, it helps reduce the flex commonly associated with molded plastic servo horns.
This red anodized arm features a 1-inch (25.4 mm) center-to-linkage-hole length, an M2 linkage hole and a Futaba-style 25-tooth spline. It is suitable for RC airplanes requiring a durable, accurately machined servo arm.
Key Features
- One-inch arm length: Measures approximately 1 inch (25.4 mm) from the center of the servo spline to the linkage hole.
- M2 linkage hole: Designed for use with M2 linkage hardware.
- Futaba-style 25T spline: Fits compatible servos using a standard 25-tooth output spline.
- Aluminum construction: CNC-machined from 6061-T6 aluminum for strength and rigidity.
- Reduced flex: Provides a more rigid linkage connection than many standard plastic servo horns.
- Anodized finish: Durable red finish helps protect the aluminum surface.
- Lightweight design: Approximately 2 grams.
Compatible Servo Splines
This arm is intended for compatible servos using a Futaba-style 25T spline, including select models from:
- Futaba
- Savox
- KingMax
- MKS
Not every servo from these manufacturers necessarily uses a 25T spline. Verify the spline specification of your exact servo before ordering.
