This black 3D‑printed leveling tool is a specialized servo and swashplate alignment fixture designed for the GAUI X3 helicopter. Its core function is to precisely calibrate the horizontal alignment of the servo horns and swashplate during assembly or maintenance, ensuring that the helicopter’s mechanical components are optimized for peak performance.

✨ Core Features

1. Precise Leveling: By sliding the central hole over the main spindle and leveraging its symmetrical three‑arm design, this tool serves as an intuitive reference point to quickly assess and adjust the height of the three servo horns, keeping the swashplate perfectly level and preventing flight instability caused by mechanical misalignment.

2. Component Protection: During the leveling process, the tool prevents direct contact between your hands or other tools and the delicate servo mechanisms and swashplate, minimizing wear and damage to critical components such as bearings and linkages.

3. Enhanced Efficiency: Compared to traditional methods like visual inspection or ruler-based measurements, this leveling tool significantly reduces setup time while delivering superior accuracy—making it an indispensable tool for professional model aircraft enthusiasts.

🎨 Design & Materials

• Custom Precision Fit: Tailored to the GAUI X3’s main spindle diameter, servo placement, and swashplate dimensions, this tool ensures a snug, vibration‑free fit after installation, with no wobble or misalignment.

• Lightweight and Durable: Crafted from high‑strength 3D printing materials such as PETG or nylon, the tool offers exceptional rigidity while remaining incredibly lightweight—without compromising the helicopter’s overall balance.

• Optimized Structure: The three‑arm, symmetrical design provides a stable visual reference during leveling, while precision machining of the central hole guarantees perfect coaxial alignment with the main spindle.

📦 Application Scenarios

• New Assembly: When assembling the GAUI X3, use the leveling tool to accurately align the servos and swashplate, laying a solid foundation for optimal flight performance.

• Maintenance and Overhaul: After replacing servos, linkages, or the swashplate, re‑level the system to restore precise mechanical alignment and ensure consistent, reliable operation.
