The Phantom 3 Motor with counterclockwise threading (CCW) is for propellers that use the same rotational direction. The Phantom 3 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. This part is for the Phantom 3 only, and may not work correctly if installed in other Phantom models.
Note: Installation requires soldering.
