Detailed Overview of the 360-Grade Tail Tube Support for RC Helicopters

This red 3D‑printed tail tube support is a dedicated accessory designed specifically for 360‑grade RC helicopters—such as the GAUI X3 and similar models—and serves primarily to protect the tail tube, aid in fine‑tuning adjustments, and ensure safe storage.

✨ Core Features

1. Protection for the Tail Tube and Tail Rotor

   • When the helicopter is laid flat on a table or the ground, the support plate acts as a “foot pad,” lifting the tail tube and tail rotor assembly clear of hard surfaces to prevent scratches on the tail tube, deformation of the tail rotor blades, or damage to the tail shaft.

   • It also safeguards the expensive carbon fiber tail rotor by preventing collisions with other objects during handling or storage.

2. Adjustment Assistance and Leveling

   • The support plate’s flat, straight base provides a stable reference surface, allowing the helicopter to be placed securely for precise calibration of critical parameters such as tail rotor pitch and tail servo travel.

   • When used in conjunction with a main rotor leveling device, it ensures that the helicopter’s overall mechanical structure remains in optimal condition, minimizing flight yaw caused by tail rotor misalignment.

3. Roll Prevention and Stability

   • The unique L‑shaped support legs effectively prevent the helicopter from rolling on smooth tabletops or test stands, enhancing operational stability and safety.

🎨 Design and Materials

• Precision Fit: Custom‑made to match the tail tube diameter and tail rotor mounting position of 360‑grade helicopters, the support is secured to the tail tube via screws, ensuring precise positioning of the support points and even load distribution.

• Lightweight and Durable: We recommend using high‑strength 3D printing materials such as PETG or nylon—these materials offer robust rigidity while remaining incredibly lightweight, ensuring they won’t compromise the helicopter’s flight balance.

• Structural Optimization:

  • Hollowed‑out design: While reducing weight, this design maintains structural integrity and allows easy inspection of the tail tube interior.

  • L‑shaped support legs: Provide firm support and roll‑prevention capabilities.

  • Screw hole placement: Designed with either three‑point or two‑point fastening options to ensure secure installation, preventing loosening due to vibration.

📦 Application Scenarios

• Workbench Adjustments: When calibrating tail rotor pitch or tail servo travel, place the helicopter steadily on the support to avoid rolling or accidental impacts.

• Everyday Storage: Lay the helicopter flat on a desk or inside a toolbox to protect the tail tube and tail rotor from damage.

• Portable Transport: At flying sites, quickly set the helicopter down on the ground or in a case—no additional stands required.

• Transport Protection: When packing the helicopter into a backpack or storage box, the support plate acts as a cushion, minimizing pressure and potential damage to the tail tube.

💡 Installation and Usage Tips

1. Installation: Secure the support plate to the tail tube using two or three small screws, ensuring it remains parallel to the tail rotor’s plane of rotation.

2. Adjustments: Place the helicopter flat on a table; at this point, the tail tube should be perfectly level.

3. Maintenance: Regularly check screw connections for looseness, and replace any cracked or deformed components promptly.
