Description

The Pro-Range 2540 Flash PC propellers are engineered for pilots seeking a reliable performance upgrade for their micro and small-scale FPV drones. The three-blade design and 2.4-inch pitch are calibrated to generate efficient thrust while maintaining manageable amp draw on 2S and 3S LiPo battery systems, extending flight times without sacrificing agility.

Manufactured from high-grade Polycarbonate, these blades achieve an optimal strength-to-weight ratio, resisting deformation and cracking during high-speed maneuvers and minor impacts. The 1.5mm shaft bore ensures a secure fit on a broad spectrum of micro brushless motors, making them a versatile choice for various lightweight quadcopter builds.

Key Features

  • High-Performance Polycarbonate Construction: Delivers superior rigidity and fatigue resistance compared to standard nylon, ensuring consistent performance and longevity.
  • Optimized Aerodynamic Profile: The 2540 size with a 2.4-inch pitch is designed for a balanced mix of thrust and efficiency, ideal for freestyle and light racing applications.
  • Precision Balancing: Each propeller is manufactured to tight tolerances, reducing vibration for smoother video footage and less strain on motor bearings.
  • Wide Motor Shaft Compatibility: The 1.5mm center bore fits the majority of micro and small drone brushless motors, simplifying the parts selection process.
  • Enhanced Visual Tracking: The bright Lemon Yellow finish provides excellent visual contrast against most backgrounds, aiding in orientation during high-speed flight.
  • Complete Flight Set: The 4CW+4CCW package provides a full set of spares, allowing for quick field replacements and maintaining balanced flight characteristics.

Applications

  • Ideal for 2.5-inch to 3-inch micro FPV freestyle and racing drones operating on 2S-3S LiPo batteries.
  • Perfect upgrade for lightweight CineWhoop builds requiring durable props for indoor/outdoor cinematic flying.
  • Suitable for small-scale DIY quadcopter projects and micro long-range builds where efficiency and low weight are critical.
  • Excellent choice for toothpick-class drones needing responsive propellers for acrobatic maneuvers.

Frequently Asked Questions

What size motors are these 2540 propellers compatible with?

The Pro-Range 2540 propellers are designed for micro and small drone motors with a 1.5mm shaft diameter. They are an ideal match for popular motor sizes such as 1103, 1204, and 1303, commonly used in 2.5-inch to 3-inch lightweight FPV builds. Always verify your motor's shaft size before installation.

What is the recommended battery voltage (S count) for these props?

These 2540 propellers with a 2.4-inch pitch are optimized for 2S and 3S LiPo battery systems. Using them with 2S provides efficient, longer flight times, while 3S unlocks higher thrust and more aggressive performance for freestyle and light racing. Exceeding 3S may over-stress the motors and is not recommended.

Are these propellers pre-balanced, and do I need to balance them?

Pro-Range propellers are manufactured to precise tolerances, offering good out-of-the-box balance suitable for most FPV applications. For the absolute smoothest performance, especially for long-range or cinematic filming where minimal vibration is critical, fine-tuning with a propeller balancer is always recommended.
