Propeller Spinner (M5)

If your motor has an M5 screw to mount the props, you can put these spinners on top to route the air nicely around the motor. It is also nice if you put your copter upside down for maintenance or to (un)mount your battery.

Internally, the M5 bolt of your motor fits over a length of 10mm. The bottom 4mm are additionally larger to make room for a nut. So this spinner was designed for motors where you put on props with a nut on an M5 bolt, which then can stand out further up to 6mm above the nut
