HQProp Ultralight 1.8X1.3X3 45MM 3-Blade Propeller Gray (2CW+2CCW)

HQProp Ultralight 1.8X1.3X3 45MM 3-Blade Propeller Gray (2CW+2CCW)

Product description

The HQProp Ultralight 1.8x1.3x3 three-blade propellers are designed for lightweight Whoop and micro FPV drones, where every gram counts. With a diameter of 45 mm, a pitch of 1.3 inches, and a weight of just 0.35 g per propeller, they are particularly well-suited for compact FPV builds with small motors.

The low pitch ensures smooth, controllable thrust delivery, making these propellers ideal for precise flight maneuvers in tight spaces. The three propeller blades provide a balanced combination of thrust and responsiveness. Especially with lightweight Whoop drones, rapid changes in RPM and minimal rotating mass are crucial.

Made of flexible polycarbonate, the HQProp 45 mm Whoop Propellers are resistant to minor collisions. The 1.5-mm shaft mount allows for installation on compatible micro motors. Thanks to the compact hub—4 mm in diameter and 5 mm thick—the propellers take up very little space.

The set includes two clockwise (CW) and two counterclockwise (CCW) propellers in gray. This gives you a complete set for your micro FPV quadcopter—whether for a new Whoop build or as a replacement after a crash.
