Here's the setup instructions for mine, give them a try
1) Switch your transmitter on and hold the
throttle in the full reverse/brake position.
2 Switch on esc using the on/off switch.
NOTE: When you switch on, the red and green LEDs will come
on, go out and the controller will beep, the green LED will come
on on its own.
3) Whilst the green LED is on, push the throttle
to the full forwards position, hold there until the
green LED goes out and the red LED comes on.
4) Whilst the red LED is on, return to neutral.
5) Calibration to the transmitter is complete and
your speed control is ready to use with last
used settings
When the red and green LEDs come on, this denotes that you are
in the neutral position.
Both LEDs will go out when you move in either direction, then the
green LED will come on at full speed in either direction.
If you want to repeat the set up procedure you must switch the
unit off for 10 seconds before trying again.
