Features: Experience unparalleled speed with the 5152-3 Propellers specifically for FPV racing drones to deliver exceptional thrusts and rapidly response. From high strength PC, these propellers reduce overall weight while enhancing durability and flight performances. The paddles thin and light, and the response speed is extremely fast. Careful selection of materials, high-efficiency explosions resistance: polycarbonate (PC) material, impact resistance, bending resistance, high-efficiency explosions resistance. Steady, agiled and no tremoring: 5152-3 with good tension at medium and fast speed and fast response speed. Compared with the tremoring problem of other brands of propellers flying at fast speed, 5152-3 not with tremoring at fast speed and is more stable and agiled.
