These well made CNC aluminum adapters are designed to adapt folding propellers to motors with a standard 3.17mm shaft.
The Adapters can handle a range of blades from 5~12 inch props, and help make your Multirotor a little easier to transport, folding back towards the boom arms much like transporting an RC helicopter.
The adapters are secured to the motor shaft by grub screws and they are suitable for any motors with a 3mm shaft.
Various colors are available to aid in rotation identification.
Grub screws and propeller mounting bolts included.
