Good motor for 1/18 cars. Difficult to fit due to unusual shape (longer than 40mm due to large bearings). Looks at the front side as what you see on the picture on the back. Motor mount might need modification. Power is OK. Does not work with Turnigy TrackStar 25A 1/18th Scale ESC! Lots of cogging, Does not fit in Mini inferno. However, if it fits it is a nice motor.
