Two blades trade a tri-blade's grip for cruise efficiency, which is why bi-blades sit on long-range and endurance platforms. The line covers a 7-inch fixed bi-blade for long-range FPV and folding bi-blades in 6-inch and 10-inch for airframes that pack.
Material follows application, not size: glass-fiber-reinforced PA66 where a platform needs stiffness under load, polycarbonate where it needs impact survival and low rotational mass. Several sizes are offered in both.
