The paddles thin and light, and the response speed is extremely fast From high strength PC, these propellers reduce overall weight while enhancing durability and flight performances Careful selection, high-efficiency explosions resistance: polycarbonate (PC), bending resistance, high-efficiency explosions resistance Steadily, agiled and not with tremoring: 5152-3 with good tension at mediumed and fast speed and fast responsing 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 unparalleled speed with the 5152-3 Propellers specifically for FPV Quadcopters to deliver exceptionally thrusts and rapidly response
