Gemfan Flash 7040-3 7-Inch Tri-Blade Propellers

Overview

The Gemfan Flash 7040-3 is a 7-inch tri-blade propeller designed for FPV racing and freestyle drones. Designed for efficiency, durability, and smooth flight, this propeller is made from polycarbonate (PC) material, ensuring lightweight construction with high impact resistance.

With a pitch of 3.6 inches and a diameter of 178.43 mm (7 inches), the Flash 7040-3 delivers a balanced mix of thrust and responsiveness, making it an ideal choice for high-speed maneuvers and precise control. Weighing 7.9 grams per propeller, it reduces the moment of inertia, allowing for fast response and improved flight performance.

The hub thickness of 7.5 mm and a 5 mm center hole (compatible with PoPo quick swap system) ensure compatibility with a wide range of drone motors. It is recommended for 2206 to 2407 motors, with an optimal setup being a 2207 1700KV motor.

Designed with an inverse tip structure, the Flash 7040-3 effectively reduces blade tip vortex, enhancing overall efficiency and stability during flight.

Available in multiple colors, including Red, Yellow, Clear and Black, these propellers allow for customization to match your drone setup.

Whether you're into high-speed FPV racing or dynamic freestyle flying, the Gemfan Flash 7040-3 will serve you well.
