Secraft 20mm (.79") V1 Aluminum Servo Arm – Futaba 25T (Red)

Replace flexible plastic servo horns with the precision and strength of a CNC-machined Secraft aluminum servo arm. Designed for high-performance RC airplanes, helicopters, and giant-scale aircraft, this servo arm delivers accurate control with virtually no flex under load.

The V1 servo arm is machined from aircraft-grade 6061-T6 aluminum, then anodized for corrosion resistance and an attractive finish. The lightweight design minimizes rotating mass while providing excellent durability for demanding flying conditions.

🚀 Target Applications:

  • High-performance RC aerobatic and sport airplanes requiring zero-flex response
  • Performance RC helicopters and complex scale giant-scale aircraft builds
  • Precision control surface pushrod geometries matching a 20mm center-to-hole layout
⚠ Spline & Linkage Sizing Note: Cut with an industry-standard Futaba 25T spline configuration and an M2 metric threaded pushrod linkage anchor hole. Always follow your aircraft manufacturer's recommended servo arm lengths to prevent excessive mechanical leverage loads on your electronics.

Key Features

  • 6061-T6 Aluminum Core: CNC machine-milled from top-grade aircraft aluminum alloy to eliminate the sloppy tracking flex typical of stock nylon servo horns.
  • Universal 25T Spline Track: Engineered for a perfect, play-free mechanical slide-fit over standard 25-tooth output splines across multiple servo brands.
  • Featherweight Rotating Mass: Keeps parasitic rotation weight down to an absolute minimum, scaling in at a negligible weight of approximately 1 gram.
  • Corrosion-Proof Shell: Shipped with a brilliant, highly durable red anodized finish that shields raw alloy surfaces against fuel and moisture residues.
  • Remover Tool Compatible: This exact V1 profile is custom-milled to drop seamlessly inside our Secraft Servo Arm Remover Tool for completely damage-free extraction loops.

💡 Modeler’s Tips & Installation

When hooking up your linkages, try to mount the pushrod's ball link underneath the aluminum servo arm face whenever possible to keep twisting force leverage on the servo bearing tower down to a minimum. Keep all connecting control rods adjusted clean and free of play. Always verify you are using a thread-locking compound on all metal-to-metal central screw fasteners during final workbench tracking assembly to safeguard against flight vibrations.
