1/4 scale ACA Cyclone 120/125 siren

mini aca cyclone for use with the Samsung microwave blower motors

all parts require supports but the supports on the rotor are optional

all hardware for mounting the stator to the motor is included on the motor 

the rotor is intended to press fit to the motor shaft the other components need glue (superglue or hot glue)

the rotor and stator will both need to be sanded to get good tolerances
