HQ Prop HeadsUpFPV R38 5.1X3.8X3 Propeller Gray
by HQ

The HQProp HeadsUp Racing Prop R38 (R38-PC-GRAY) is a high-performance 5.1-inch tri-blade propeller designed in collaboration with multi-time world champion pilot Evan Turner (HeadsUpFPV). Engineered to be the ultimate racing propeller, the R38 bridge the gap between extremely responsive low-pitch props and high-speed racing blades. It features a unique 3.8-inch pitch that delivers a highly linear thrust curve, providing pilots with precise low-end throttle control for technical gates and the blistering top-end speed required for long straights.

Constructed from premium Polycarbonate (PC), the R38 is optimized for "grip" in the air, offering a smooth and connected feel that allows for tighter cornering and aggressive recovery maneuvers. Despite its lightweight 4.4g profile, the propeller maintains exceptional durability, capable of being bent back and flown after minor impacts—a critical feature for competitive racing. For university aerospace programs and tactical sUAS developers, the R38 offers a refined propulsion solution that maximizes agility without sacrificing the efficiency needed for high-voltage 6S or 8S power systems.
