Right,
I have just tried adjust the hi points and no change
Then,
I changed the timing on the motor itself from 0 degrees to 20 and tried it across the floor and it has stopped doing it

, changed back to 0 degrees and soon as i blipped it across the floor it started again tried it on 5 degrees and it was still doing,this is a bit strange really?? i have set it at 20 degrees and will go from there
I will try it Tuesday Night when i race next and see how it goes
