Secraft Full Width Servo Arm – 2.5" (4-40) Aluminum
The Secraft Full Width Servo Arm is a precision CNC-machined aluminum arm designed for high-load RC aircraft applications. The full-width (double arm) design provides balanced force distribution, making it ideal for rudder and pull-pull control setups.
At 2.5" (63mm), this arm delivers maximum control throw and authority while maintaining rigidity and precision.
⚖️ Balanced Load Distribution
Full-width servo arms provide symmetrical load distribution, reducing stress on the servo output shaft and improving control accuracy—especially important in high-load applications like rudders.
Key Features
- Full-width (double arm) design for balanced linkage geometry
- High-strength 6061-T6 aluminum construction
- Increased rigidity vs plastic arms
- Ideal for rudder and large control surfaces
