APC B7x5E-B4 Props, Quad-Copter Bundle
by APC

The APC B7x5E-B4 7x5 Electric Quad-Copter Propeller Bundle is a precision-molded four-propeller set engineered specifically for multirotor and quadcopter platforms requiring 7-inch propellers. Manufactured by Advanced Precision Composites (APC), this factory-matched set includes two standard (clockwise) and two reverse (counter-clockwise) rotation 7x5 Thin Electric propellers optimized for low vibration, efficient thrust delivery, and rigid performance on brushless electric motors.

Engineered from APC's signature long glass fiber reinforced composite material, these propellers maintain structural integrity under high motor RPM and sudden throttle changes, significantly reducing blade flexing compared to standard flexible plastic props. Ideal for mid-sized aerial imaging drones, 7-inch endurance quads, and custom multirotor airframes, this set ensures balanced, predictable flight characteristics across all four rotors.

Key Features

• Complete Quadcopter 4-Propeller Set: Includes two standard rotation (CW) and two reverse rotation (CCW) propellers tailored for 4-rotor drone setups.

• APC Thin Electric Airfoil Geometry: Designed specifically for electric motor efficiency, delivering quiet flight, high thrust output, and lower battery drain.

• Glass Fiber Reinforced Composite: High-rigidity composite material minimizes blade flex under heavy acceleration and aerodynamic stress.

• Precision Factory Balance: Molded to tight tolerances to reduce high-frequency motor vibrations and flight controller gyro noise.

• Included Adapter Ring Sets: Comes with composite shaft adapter rings (location rings) to ensure a true, centered fit on various motor shaft diameters.
