This polished aluminum giant-scale servo arm is clear anodized and laser etched after being CNC-machined from a solid billet of 6061 T6 aircraft aluminum. Broached to fit ProModeler (and Futaba) servos (25-splines), this unit is perfect for heavy duty applications like aileron and elevator because because it features a dual cinching mechanism to help secure the servo arm to the splines (necessary for extreme flight loads). Drilled and tapped for 4-40 threads, this is a smart choice when high flight loads are part of the equation.
Dimensions: 25-spline (Futaba-compatible)
