Description

The Pro-Range 2540 Flash PC propellers are engineered for micro and lightweight FPV drone applications where a balance of thrust, efficiency, and durability is critical. The 2.4-inch pitch and 63.5mm diameter provide a responsive flight character suitable for agile freestyle and racing maneuvers on 2.5-inch class builds.

Manufactured from high-grade polycarbonate, these triblade propellers deliver excellent impact resistance and structural integrity, minimizing flex at high rotational speeds. The 5mm thick hub and precise molding ensure consistent balance across the set, reducing vibration for smoother video footage and extended motor bearing life.

Key Features

High-Grade Polycarbonate Construction: Offers superior durability and impact resistance compared to standard nylon blends, maintaining blade integrity during minor strikes.
Optimized 2.4-Inch Pitch: Engineered for a favorable thrust-to-power draw ratio, providing responsive acceleration without excessively taxing the motor and ESC system.
1.5mm Universal Bore: Compatible with the vast majority of 1103, 1104, 1204, and 1303 brushless motor shafts common in micro FPV and lightweight drone builds.
Precision-Balanced Design: Each propeller is manufactured to tight tolerances, reducing the need for manual balancing and ensuring minimal vibration out of the package.
Enhanced Hub Design: The 5mm thick center hub increases mounting surface area and rigidity, improving power transfer and reducing the risk of hub cracking.
Vibrant White Finish: Provides high visibility for orientation during flight and a clean, professional aesthetic for finished builds.

Applications

2.5-inch Micro FPV Racing Drones: Ideal for lightweight, high-speed builds using 1104-1303 sized motors on 2S-3S LiPo batteries.
Lightweight 3-inch Cinewhoop & Freestyle Drones: Suitable for low-drag, efficient builds prioritizing flight time and smooth cinematic footage.
Tiny Whoop & Toothpick-Class Upgrades: Provides a performance boost over stock plastic props on micro brushed and brushless platforms.
Lightweight Long-Range & Exploration Micro Drones: The efficient pitch and low weight contribute to extended flight endurance on small battery packs.

Frequently Asked Questions

What size motors are these 2540 propellers compatible with?

These propellers are designed for motors with a 1.5mm shaft diameter, which is standard for many 1103, 1104, 1204, and 1303 brushless motors commonly used in 2.5-inch and lightweight 3-inch micro drone builds. Always verify your motor's shaft size before installation.

What is the advantage of the polycarbonate (PC) material?

Polycarbonate offers a superior strength-to-weight ratio and higher impact resistance compared to standard nylon or glass-filled nylon (GFN) propellers. This means the 2540 Flash props are less likely to shatter or crack upon minor impacts, providing greater durability for aggressive flying while remaining lightweight.

Are these propellers suitable for 4S battery setups on a micro drone?

While the polycarbonate construction is durable, the 2540 size and 2.4-inch pitch are primarily optimized for 2S and 3S LiPo setups on micro drones. Using them on 4S with high-KV motors may lead to excessive power draw, motor overheating, and potential blade deformation. Check your motor's maximum recommended prop load for 4S operation.

Do I need to balance these propellers before use?

Pro-Range propellers are manufactured to good tolerances and are typically well-balanced out of the package, making them flight-ready. However, for the absolute smoothest performance, especially in high-RPM applications or for minimizing video jello, final dynamic balancing is always recommended.
