Gator RC 50mm (2") Full Width Aluminum Servo Arm – Futaba 25T Blue

The Gator RC 50mm (2") Full Width Aluminum Servo Arm is a heavy-duty servo arm designed for Futaba-style 25T spline servos. Its full-width construction provides increased rigidity for demanding control surface applications, making it an excellent choice for rudder installations on giant scale, IMAC, aerobatic, sport, and scale aircraft.

Manufactured from lightweight CNC-machined aluminum and finished in a durable blue anodized coating, this servo arm combines strength with low weight while providing multiple linkage mounting positions for setup flexibility.

Key Features

  • Heavy-duty full-width servo arm design
  • Fits Futaba-style 25T spline servos
  • 50mm (2") overall length
  • Multiple linkage mounting positions at 10mm, 15mm, and 20mm from center
  • Precision CNC-machined aluminum construction
  • Blue anodized finish
  • 3mm arm thickness
  • 7mm hub height
  • Excellent for rudder and high-load control surface applications
  • Compatible with KingMax, Futaba, Graupner, and MKS servos using a 25T spline

Why Choose a Full Width Servo Arm?

Full-width servo arms distribute loads evenly across both sides of the servo output spline, helping provide a rigid and reliable connection for larger control surfaces. This design is particularly beneficial on rudder installations where higher aerodynamic loads are common.

The multiple mounting positions allow pilots to fine-tune control throw and mechanical advantage to suit their aircraft and flying style.
