This is a custom propeller quick‑release tool designed for SUNNYSKY motors, specifically addressing the common issues of slipping and excessive effort when tightening or loosening propeller nuts on FPV race drones or model aircraft.

Core Functions

• Anti-Slip & Easy to Apply Torque: The tool features a specialized concave design that securely grips the outer contour of the propeller nut, preventing slippage when tightening with bare hands or standard tools—allowing you to apply torque more effortlessly and with greater precision.

• Protects Critical Components: By eliminating slip-induced thread damage to propeller nuts, shaft deformation in the motor, or blade fractures, this quick‑release tool helps extend the service life of wear‑prone parts, ensuring long‑term reliability and performance.

• Boosts Operational Efficiency: Whether replacing propellers or performing motor maintenance, this tool significantly reduces setup time—making it an ideal solution for competitive racing or 3D flight scenarios where frequent propeller changes are required.

Design Features

• Precision Fit: Optimized for the most commonly used propeller nut sizes on SUNNYSKY motors, the quick‑release tool perfectly matches the contours of each nut, ensuring a snug and secure fit every time.

• Ergonomic Design: The flat, contoured grip provides a comfortable, easy‑to‑grip handle, allowing for smooth, efficient operation even during extended use.

• Lightweight and Durable: Crafted from high‑strength 3D‑printed materials, this quick‑release tool delivers robust performance without adding unnecessary weight to your aircraft—a key consideration for both speed and endurance in flight.

How to Use

1. Align the concave end of the quick‑release tool with the propeller nut and gently snap it into place.

2. Secure the motor or airframe with your other hand to prevent movement.

3. Simply rotate the quick‑release tool to tighten or loosen the propeller nut with ease, enabling rapid propeller swaps in seconds.
