Package Include 4pair 55mm Propeller (4 x CW & 4 x CCW) One of the most popular DIY projects people make are Drones. They may come with two propellers or four propellers according to the design and freedom of movement you desire from your Drone. We usually use coreless BLDC motors as drone motors to rotate the propellers which comes with its own propeller mounting mechanism, so you don’t have to worry about mounting the propellers on these motors. Bigger the propellers, more lift will be produced by them but this decision also depends on the size of the drone you are planning to build. These 55mm Drone propellers fit snugly onto the shaft of the coreless motors. They are strong and lightweight with durable plastic material.
