HQProp 7X4.5 2-Blade Propeller (Set of 4) Light Grey
by HQ

The HQProp 7X4.5 2-Blade Propeller (Set of 4) Light Grey is a highly efficient, dual-blade (bi-blade) propulsion solution optimized for long-range FPV drones, mid-weight exploration platforms, and long-endurance sUAS applications. Featuring a 7-inch diameter combined with a versatile 4.5-inch pitch, this propeller is explicitly designed to minimize power consumption and motor amp draw during steady cruise flight. By choosing a two-blade design over a tri-blade configuration, it reduces rotational load and aerodynamic drag, maximizing flight time on sub-250g long-range builds or lightweight 7-inch endurance multirotors.

Constructed from an advanced, high-impact Polycarbonate (PC) compound, these propellers exhibit a perfect blend of structural flexing resilience and durability. The material profile ensures they can withstand minor branch clipping or rough landings without shattering, while maintaining an optimized airfoil shape during smooth, efficient cruising. Widely integrated across university aerospace testing facilities and tactical drone sensor development groups, the 7X4.5 features a standard 5mm shaft mounting interface, allowing it to drop directly onto standard micro to mid-sized long-range brushless motor hubs.
