The 2312 Motor for Phantom 3 Professional / Advanced with counterclockwise threading (CCW) is for propellers that use the same rotational direction. The quadcopter has four motors total, two clockwise (CW) and two counter-clockwise (CCW). It is important to replace the motor with one of the same thread orientation to ensure the props do not come loose during flight.

Note: These motors will only work with Phantom 3 Professional/Advanced models that have the first-generation central board (Part 33). They will not work with the newer central board (Part 96). Additionally, they will not work with the Phantom 3 Standard
