Gemfan Flash Army 7040 Propeller 4pcs CW/CWW (7X4X3)

The original Gemfan Flash Army 7040 propeller set is a well-engineered solution for small and medium quadcopters, combining reliability, optimal aerodynamics, and precise balancing. The set is designed for an inner mounting diameter of 5 mm (POPO) and is suitable for motors with a corresponding mount. The propellers are made of durable PC material, ensuring impact resistance, longevity, and maintaining the blade's working geometry even during intense maneuvers.

Key Advantages

• Three blades for increased lift and better control during turns and aggressive maneuvers.
• 7-inch size and 4-inch pitch provide a balanced combination of thrust and maneuverability for various flight styles.
• 7.5 mm hub thickness ensures secure attachment to the motor shaft and minimizes play.
• Low weight — 7.9 g per propeller — contributes to overall system efficiency and battery life.

Package Contents:

2 x Gemfan Flash Army 7040 CW propellers
2 x Gemfan Flash Army 7040 CCW propellers

This set of four propellers (2 CW + 2 CCW) is ideal for quickly restoring quadcopter functionality after damage or for upgrading the thrust system. The PC material provides good resistance to mechanical stress, and the three-blade design adds lift without significant loss of control. The parameters — 7 inches, 4-inch pitch, 7.5 mm hub thickness, and 5 mm inner diameter — make the set compatible with many popular motors and frames that support POPO mounting.

Before installation, ensure that your motor and mounting hole are compatible with the 5 mm inner diameter and 7.5 mm hub thickness. For proper operation, it is recommended to check the propeller balance after mounting and use the set in CW/CCW pairs according to motor placement. If you need a replacement for the Gemfan Flash Army 7040 model, this set combines an affordable price with the quality of original components.

Operational advantages: long service life due to PC, stable thrust at medium RPMs, and relatively low weight for increased overall battery efficiency. Please note that specifications and package contents may be changed by the manufacturer without notice.
