The ESC in most cases will have been calibrated before you receive it. There are ways to check this however if you are not sure:

Switch on the handset first and then the car. Notice how the LED reacts as you use the handset so place the car on something which will allow the wheels to spin freely i.e. tin of paint.

Forward (pull the trigger towards you and wheels should spin forwards) - LED should shine as per the motor speed.

Brake (trigger in the neutral position, wheels should now be stationary) - LED blinks.

Reverse (push the trigger away from you and the wheels should spin in reverse) - LED shines solidly.

Note: the car when moving in forward motion can not go into reverse motion immediately. There is brake delay time so the handset will first need to go into neutral for 0.35 seconds before you begin reversing.

If you are not experiencing forward motion, reverse motion or both, first check your trims (also on our help page). If this does not make any difference your car may not be calibrated so use the procedure below:

* Handset and car switched on.

* With the handset in neutral, press and hold the set-up button for 1 second until the LED blinks once/motor bleeps once. Neutral set-up is finished.

* Pull the trigger towards you, press and hold the set-up button for 1 second until the LED blinks twice/motor beeps twice. Forward set-up is finished.

* Push the trigger away from you, press and hold the set-up button for 1 second until the LED blinks three times/motor beeps three times. Reverse set-up is finished.
