It doesn't have anything in the manual about programming it but I found this (
http://www.rctech.net/forum/radio-el...ka-15-esc.html) and following the instructions on there doesn't seem to work

Am I definitely doing it right...?
>Switch TX then receiver on
>Hold the setup button for at least 2 seconds then release
>Pull the trigger then press the setup button again (I guess only press rather than hold?)
>Push the trigger then press the setup button again (I guess only press rather than hold?)
>Let go of the trigger then pust setup button
And then it should be sorted straight away, or should I be doing something else?
When you say that the ESC might be set badly, do you mean it might have done this itself as the car has been working just fine for the last week or so, just that yesterday it decided to start playing up?
