The timing advance with Castle Creations ESCS is dynamic, it changes with the speed of the motor. This assures the motor is running at it's most efficient timing regardless of speed. This is one of the big advantages of a good sensorless over sensored system. Sensored systems. This is possible because the ESC reads the motor's back EMF directly, not pulses from sensors. When you change timing you are simply changing the range the timing moves within. A motor will be more efficient at 'normal' timing, slightly higher Kv at the expense of a huge decrease in efficiency at higher timings and more efficient with a slight decrease in high speed RPM at low timing.

Delta wind motors do not respond to timing and at higher timing get extremely inefficient and kill batteries and ESCS. We no no sell D wind motors and it is my informed opinion that they have no place in surface vehicles and only limited use in high speed airplanes that are run for short periods of time.
