The Dual Sky DSA-21778 SA-3.5 is a CNC-machined aluminium double servo arm designed for use with 25T spline servos across a wide range of RC applications. Finished in blue anodised aluminium, this 3.5-inch servo arm offers a rigid, lightweight alternative to standard plastic arms, making it a practical choice for builds where durability and precision linkage geometry matter.

Key Features

  • CNC-machined from aluminium for greater rigidity and resistance to flex compared to plastic servo arms
  • Blue anodised finish provides corrosion resistance and a clean appearance
  • 3.5-inch arm length suits a range of linkage setups in RC cars, crawlers, and aircraft
  • 25T spline pattern is a widely used standard compatible with many popular servo brands
  • Double arm configuration allows linkage connections on both sides of the servo output shaft
