Great setup for the price but the motor is not sensored and the ESC does not have timing control. If your track and class allow for timing in the ESC, you want an ESC such as the MMP with timing control and a motor with a sensor port. You can run sensored motors in unsensored mode but at least you have the option to run sensored and with timing control.

My 17.5T brushless sensored motor with Castle MMP and timing will smoke the sidewinder setup.
