This red 3D‑printed component is a specialized horizontal tail rotor leveler designed for the GAUI X3 helicopter. Its primary function is to precisely calibrate the horizontal alignment of the tail rotor during installation or maintenance, ensuring optimal flight stability.

✨ Core Features

1. Precise Leveling: By mounting securely onto the tail boom, this leveler serves as an intuitive reference point, enabling rapid and accurate adjustment of the tail rotor angle to keep it parallel with the main rotor plane—preventing flight yaw or unstable autorotation caused by tail rotor misalignment.

2. Enhanced Efficiency: Compared to traditional methods like visual inspection or ruler-based measurements, this leveler significantly reduces leveling 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 tail boom diameter, tail rotor dimensions, and overall layout, this leveler ensures a snug, vibration‑free fit once installed, with no wobble or lateral displacement.

• Lightweight and Durable: Crafted from high‑strength 3D printing materials such as PETG or nylon, this leveler offers exceptional rigidity while maintaining an ultra‑light weight, ensuring it has minimal impact on the helicopter’s overall balance.

• Optimized Structure: The streamlined, wing‑shaped design provides a stable visual reference during leveling, while the elongated central slot and screw holes ensure secure attachment to the tail boom.
