HQProp Thin Electric Prop 7X7R (2CW)
by HQ

The HQProp Thin Electric Prop 7X7R (2CW) is a specialized, high-efficiency propeller designed for fixed-wing aircraft and long-range sUAS platforms that require a precise balance of thrust and airspeed. Part of HQProp’s "Thin Electric" series, this propeller features a square 7-inch diameter and 7-inch pitch configuration, optimized to deliver consistent torque across a wide RPM range. Constructed from a durable nylon composite, the 7X7R is engineered to maintain aerodynamic rigidity while offering the resilience needed for rough field landings and high-speed maneuvers.

This propeller is a critical component for university aerospace departments and STEM programs, providing a standard baseline for studying propeller efficiency and motor-to-prop matching. For government contractors and industrial sUAS manufacturers, the "R" (Reverse/Clockwise) rotation is essential for pusher-configuration fixed-wing drones or multi-engine aircraft requiring counter-rotating pairs for torque cancellation. The inclusion of multiple adapter rings ensures compatibility with a vast array of motor shaft diameters, making it one of the most versatile 7-inch props for tactical and research applications.
