The Z1407 4100Kv motors have a strong steel 2mm internal shaft and 5mm external non-rotation specific prop shaft. The prop shaft supports 5mm shaft props with no adapter need, saving you weight. Each motor comes with two ultra-lightweight, black anodized, low profile, flanged aluminum lock, ensuring your propellers do not come loose during flight.Each motor comes with YFS 4x M2x4(for 2mm bottom plate) and YFS 4x M2x5(for 3mm bottom plate) screws for mounting on most airframes. The motor wire length is 110mm for easy installation. You can also simply cut the motor wires to the desired length and directly solder them to your ESC. With the motor wires cut to a short length (and no bullets) the motor only weighs an incredible 16g!1. The Special magnet for ZoeFPV Motor.
