The Futaba aluminium servo arm (1.25 in, M3, purple) is a precision-machined control arm designed for RC aircraft and high-performance servos with a 25-tooth spline. Made from anodised aluminium, it is significantly stronger and more durable than stock plastic arms, minimizing flex and improving control responsiveness under load. 

Perfect for Futaba, Savox, MacGregor and Pilot-RC servos, this arm delivers smooth, reliable motion for a wide range of models — from sport planes to scale builds. The purple anodised finish not only looks great but resists wear and corrosion over time.

• Ideal upgrade over plastic arms for better precision

Benefits:
