Introduction to the 360-Class Short Propellers for RC Helicopters (Propellers Specifically Designed for Parameter Tuning)

These white, 3D‑printed short propellers are specially engineered as propellers dedicated to parameter tuning, designed for 360‑class RC helicopters. Their primary function is to serve as a safe and efficient replacement for real blades during installation, calibration, and maintenance—allowing operators to fine‑tune various flight parameters with confidence while minimizing risks.

✨ Core Features

1. Safe Parameter Tuning: When calibrating the flight controller, adjusting pitch settings, or testing servo response, using these short propellers in place of full‑size blades significantly reduces the safety hazards associated with high‑speed rotation, preventing injuries and equipment damage.

2. Precise Pitch Measurement: The flat, smooth surface of the short propeller provides an ideal, stable contact point for digital pitch gauges—such as the TL90—ensuring accurate and reliable pitch readings. This precise data serves as a critical foundation for optimizing flight performance during subsequent tuning sessions.

3. Space‑Efficient Design: Compared to full‑size propellers, these short blades occupy minimal space, making them incredibly convenient to use on compact workbenches or test stands. They also eliminate the risk of propeller collisions with nearby objects during operation.

4. Protects Real Blades: By reducing the frequency of blade disassembly and reassembly—and minimizing the likelihood of impacts and collisions—these short propellers help preserve the integrity of real blades, extending their service life and reducing wear and tear over time.

🎨 Design & Materials

• Precision Fit: Custom‑made to match the specific dimensions of the 360‑class helicopter’s blade grips and main shaft, ensuring that after installation, the short propellers align perfectly with the rotational plane of the real blades—guaranteeing accurate measurements and reliable calibration results.

• Lightweight and Durable: Crafted from 3D printing materials such as PLA or PETG, these propellers are exceptionally lightweight, with no adverse impact on the helicopter’s center of gravity or mechanical balance. At the same time, they offer robust structural strength capable of withstanding the vibrations encountered during debugging and tuning.

• Optimized Structure: The flat blade design provides an ideal contact surface for pitch gauges, while small holes at the blade tips make it easy to hang and store the propellers when not in use.

📦 Application Scenarios

• New Aircraft Assembly: After completing assembly, use the short propellers in conjunction with a pitch gauge to precisely calibrate each servo’s travel range and pitch curve.

• Flight Controller Debugging: During flight controller parameter tuning and automated stability tests, rely on the short propellers to ensure safe and controlled operations.

• Maintenance and Inspection: After replacing servos, linkages, or the swashplate, quickly verify that pitch settings have returned to normal.
