Arm, servo, 3-3/4"

This polished aluminum giant-scale double-side servo arm is red 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 the rudder because because it features dual clamps 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)
