Achieve a new level of smoothness in your flying with the HQProp R31 5.1×3.1×3 propeller. This 3-blade prop is engineered specifically for FPV pilots who prioritize a buttery-smooth, “juicy,” and highly controllable flight experience. With its unique low-pitch design, the R31 is the ultimate choice for technical and cinematic freestyle flying.

Engineered for Smooth Cinematic Flight. The R31 features a very low 3.1-inch pitch on a 5.1-inch blade. This combination is designed to provide an incredibly linear and smooth throttle response, giving you the precise control needed to capture flawless cinematic lines. The “floaty” characteristic of this low-pitch design is a favorite among technical freestyle pilots for its predictable handling and excellent propwash mitigation.

Durable & Balanced Crafted from a tough and durable polycarbonate material, these propellers are built to withstand the demands of freestyle flying. As a premium HQProp product, they are manufactured with extremely high tolerances, resulting in a well-balanced prop that minimizes vibrations and helps you capture clean, jello-free HD footage.
