HQProp 7037 7x3.7x3 Racing Prop FPV 7-inch 3-Blade Propeller, Gray (2CW+2CCW)

Product description

The HQProp 7037 7x3.7x3 3-blade propellers fall right into the sweet spot where FPV flying gets particularly exciting: the balance between efficiency and performance. There’s a good reason why 7-inch props are considered the sweet spot for long-range builds—they’re large enough to provide good flight times, yet still agile enough for controlled maneuvers.

With a 3.7 pitch, these propellers deliver a balanced mix of thrust and efficiency. They generate enough thrust for stable forward flight without draining the battery unnecessarily quickly. That’s exactly what makes them ideal for long distances, smooth lines, and energy-efficient flights.

The 3-blade design provides better grip in the air and stabilizes flight behavior—especially at varying speeds or when turning. The result is a smoother flight experience and greater control, which is crucial for long-range flights.

Weighing just 8.2 g, these propellers are among the lightest in their class. Less rotating mass means faster response and less strain on the motors—an often-underestimated factor for efficiency and flight time.

Mounting is via an M5 shaft mount, making them compatible with most common 22xx/23xx motors in the 7" segment.

These propellers aren’t brute-force powerhouses. They are tools for pilots who fly with intention and use their energy intelligently.
