Description

The Pro-Range 2540 Flash PC propellers are precision-molded from polycarbonate, offering a robust yet lightweight solution for micro-class FPV drones and quadcopters. The 3-blade design and 2.4-inch pitch are optimized to deliver a favorable thrust-to-weight ratio while maintaining responsive handling and flight stability.

Engineered for durability, these propellers resist deformation and cracking under high-RPM stress, making them suitable for aggressive freestyle and racing applications. The 1.5mm mounting hole ensures a secure fit on standard micro brushless motors, providing reliable power transmission without slippage.

Key Features

  • High-impact polycarbonate construction ensures longevity and crash resistance.
  • Precision-balanced blades for smooth operation and reduced motor vibration.
  • Optimized 3-blade aerodynamics provide a solid mix of thrust and efficiency.
  • 1.5mm bore diameter is standard for micro-sized brushless motor shafts.
  • Vibrant, opaque red finish for clear orientation identification and aesthetic customization.

Applications

  • 2.5-inch micro FPV racing and freestyle drone builds.
  • Lightweight cinewhoop and micro cinematic drones requiring durable props.
  • Tiny whoop and toothpick-class drones with 1.5mm motor shafts.
  • FPV drone training and practice sessions where prop durability is key.
  • Custom micro UAV projects needing high-visibility red propellers.

Frequently Asked Questions

What size motors are these 2540 propellers compatible with?

These propellers are designed for micro brushless motors with a 1.5mm shaft diameter. They are ideal for motors commonly used on 2.5-inch and similar-sized micro FPV drone frames.

Are these propellers balanced out of the package?

Pro-Range propellers are precision-molded for consistent weight distribution. While they offer good out-of-box balance, for optimal performance in high-RPM applications, fine-tuning with a propeller balancer is recommended.

Can I use these on a 3S or 4S LiPo battery system?

Yes, the polycarbonate construction can handle the RPM generated by typical micro motors on 3S and 4S LiPo power. Always ensure your motor's KV rating and propeller load are within safe limits to prevent overheating.

What is the advantage of the 3-blade design?

The 3-blade design provides a favorable compromise between thrust and efficiency. It generally offers more thrust and smoother power delivery than a 2-blade prop of the same size, with less noise and turbulence than some 4-blade designs, making it versatile for racing and freestyle.
