Abstract: Systems, devices, apparatus and methods for easily attaching and detaching blades to flywheels/rotors on motors by inserting tab portions of the root ends of the blades into sockets on the flywheel/rotor. Inserting the root end of the blades into the slots causes raised ridges to slide into and snapably lock into grooves, which automatically locks the blades to the flywheel/rotor on the ceiling fan. Bending or pulling or pushing a free end of a sheath separates the ridge from the groove which allows the root ends of the blades to be released and easily pulled out from the sockets. Another embodiment has two free ends which can be pinched or pushed together with a hinge portion between, that also separates ridges from grooves, and allows the blades to be pulled from the flywheel.
