Dual Sky DSA-21777 SA-3.0 25T CNC Aluminium 3 Inch Double Full Servo Arm Horn

The Dual Sky DSA-21777 SA-3.0 is a 25T spline CNC aluminium servo arm designed for RC applications where a longer, stiffer horn is needed for precise control linkage geometry. Machined from aluminium rather than moulded plastic, this 3-inch double full servo arm offers a more rigid connection between your servo and linkage rods, reducing flex under load. It suits any servo with a 25T spline output shaft, making it a practical choice across a wide range of RC vehicles, aircraft, and boats.

Key Features

• CNC machined aluminium construction provides greater rigidity than standard plastic servo horns
• 25T spline interface fits a widely used servo shaft standard across many brands and applications
• 3-inch arm length gives additional mechanical advantage and allows more flexible linkage routing
• Double full arm design offers two usable ends for mounting rod ends or clevises
• Compatible with Dual Sky servos and any other servo using a 25T spline output
