rpm/volt is constant(load rated). It doesn't change. Only the voltage will actually change(voltage drop=rpm drop). The 8L is similar in loaded rpms to the 2800xl Lehner motor, actually. Given the same gearing and setup, it will for sure be faster than a 1930/10 motor(unless the amp draw lowers the voltage to offset the rpm difference, but this would require pretty crappy batteries)
