Dual Sky DSA-21773 SA-1.5 Blue 25T CNC Alloy 1.5 Inch Half/Single Servo Arm

The Dual Sky DSA-21773 SA-1.5 is a CNC-machined alloy servo arm designed for 25T spline servos, giving you a solid metal alternative to standard plastic arms in a compact 1.5-inch half or single configuration. Finished in blue anodised aluminium, it's a practical upgrade for builds where a stock plastic arm isn't up to the job, particularly in applications where steering or throttle linkages are under repeated stress.

Key Features

• CNC-machined from alloy for greater rigidity and resistance to flex compared to plastic servo arms
• 25T spline fitment suits a wide range of standard-sized servos commonly used in RC cars, boats, and aircraft
• 1.5-inch arm length suits mid-range linkage setups where a shorter or longer arm would compromise geometry
• Blue anodised finish provides corrosion resistance and a clean look without adding meaningful weight
• Half and single arm profile keeps the design compact and reduces the risk of interference in tight servo bays
