Drive Frequency --

Refers to the number of times an ESC cycles the motor on and off while accelerating or at full throttle. This frequency is measured in Hz (hertz). A higher drive frequency (more cycles) equals smoother operation and better efficiency, but may provide slightly slower acceleration. Higher frequencies are best for modified motors. A lower drive frequency may seem to accelerate better, due to fewer steps, but is less efficient and may cause the motor to heat up faster or the batteries to drain quicker. Some high end ESCs allow the user to change the drive frequency or even map out the throttle curve with different frequencies. The term 'drive frequency' usually includes both the acceleration and braking frequencies, however, these usually differ, with the braking frequency being less than the acceleration frequency.
