Yes, the rotors on these models are derived from the 40V2T. Correctly wired the rotor will spin in a clockwise direction. Wired backwards the rotor will spin counterclockwise. There isn’t a whole lot in change of sound output up close but sound is being more directed out the air intake and towards the ground than out of the projectors when wired the other way. It doesn’t matter a whole lot because this town is extremely small and maybe covers like 3-4 small streets of homes in a rectangle.
