Radio Controlled Boats |

Hi i have 2 rc boats with both the same motors they both have 2x 560 motors but the 1 boat have 560 racing motors and the otherone just has 560 motors so whats the difference between a normal electric 560 motor and a electric 560 racing motor?

I would say that the motors have different angles on the prop-
and maybe 2-3 or 4 blade
