Pro-Range Hurricane 7043 PC 3-Blade Propellers (2CW+2CCW)

These propellers feature a standard 5mm center hole, making them compatible with most 5mm motor shafts. While specifically mentioned for 2811 and RAY12kv series, they will fit many common FPV motors such as 22XX, 23XX, and 24XX if the motor Kv is suitable for 7-inch props and the power system is balanced for the larger disc load.

The 3-blade design typically offers a smoother power delivery and reduced vibration compared to 2-blade props, enhancing flight stability and control. This configuration balances thrust efficiency with responsiveness, making them ideal for both precise maneuvering in freestyle and stable cruising in long-range applications.

Polycarbonate (PC) is favored for drone propellers due to its excellent balance of rigidity and flexibility. It provides good impact resistance, helping propellers survive minor crashes better than more brittle materials. This durability, combined with its lightweight properties, ensures efficient thrust and overall propeller longevity in various flight conditions.

The "7043" designation indicates the propeller's dimensions. "70" refers to a 7.0-inch diameter, while "43" signifies a 4.3-inch pitch. This combination defines the amount of air the propeller moves per revolution and its overall thrust profile. A 7-inch propeller with a 4.3 pitch is generally well-suited for efficient cruising and longer flight times.
