FPV racing is about speed and control. Engineers paid special attention to fluid mechanics. This resulted in a Unique shape with curves that result in a very powerful combination. Overall more power over the entire speed range of the engine. Performance, efficiency and speed do not bring with a fragile substance of the rotor blades. We've taken durability to a new level like no other. The focus was placed directly on a design that allows safe flying even after contacts! The new Azure power 5150 Race Propellers provide a smoother response. This ensures precise performance at high speed. Expect improved feel and responsiveness in extreme cornering and changing conditions. Efficiency is improved. This results in more stable flying at all speeds.
