DU-BRO Full Dual Servo Arm – Strong Pull-Pull Servo Arm for Large Aircraft

The DU-BRO Full Dual Servo Arm is designed for large RC aircraft that use a pull-pull servo setup and require strong, precise, and dependable control movement. This arm is built for power, accuracy, and durability—three things every large-scale pilot relies on when flying high-performance airplanes.

The Full Dual Servo Arm features a dual-arm layout that allows your control system to move in a smooth, straight, and in-line motion. This helps reduce binding, improves precision, and ensures that both sides of your pull-pull system operate evenly. Whether you’re controlling a large rudder, elevator, or other high-load surface, this servo arm provides the stability and control you need.

Made from glass-filled nylon, the arm is extremely strong while staying lightweight. It includes 4-40 swivel ball links and all the necessary hardware, giving you a clean, secure, and low-slop connection right out of the package. With four available mounting positions, you can easily fine-tune your control throw to match your aircraft’s needs.
