Dual Sky DSA-21775 SA-2.0 25T CNC Alloy Servo Arm

The Dual Sky DSA-21775 SA-2.0 is a CNC-machined alloy servo arm designed for RC applications requiring a strong, precise connection between a 25-tooth spline servo output and the control linkage. Manufactured from aluminium alloy rather than standard plastic, the DSA-21775 resists flex and distortion under load, making it a dependable choice for aircraft, cars, boats, or any RC build where servo response accuracy matters.

Key Features

• CNC-machined aluminium alloy construction offers greater rigidity and durability compared to plastic servo arms
• 25T spline fitment is a widely used standard across many RC servo brands and models
• Reduced flex under high load helps maintain precise control surface or steering response
• Suitable for use across RC aircraft, surface, and marine applications
