Dual Sky DSA-21776 SA-2.5 25T CNC Aluminium Double Servo Arm

The Dual Sky DSA-21776 SA-2.5 is a CNC-machined aluminium double servo arm designed for 25T spline servos across a wide range of RC applications. Cut from aluminium rather than moulded from plastic, it offers a more rigid connection between the servo output shaft and your linkage, making it a practical choice for steering, throttle, or control surface setups where slop or flex in a standard arm would be a problem.

Key Features

• CNC-machined aluminium construction provides greater rigidity than standard plastic servo arms
• 25T spline interface fits a widely used servo output standard across RC cars, planes, and helicopters
• Double arm design gives two mounting points for linkage attachment, offering flexibility in geometry setup
• Style code DSA-21776 identifies this as the SA-2.5 variant within the Dual Sky servo arm range
