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.

Spline and linkage sizing: This servo arm uses a Futaba-style 25T spline and is designed for M2 linkage hardware. Linkage hardware is not included. Confirm your servo’s spline type before ordering.

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.
