I took the black screw out of the servo (I think thats what its called... its a little white thing that moves a yellow bar that controls your steering

). Anyways, after I removed that screw, I tried to re-align it like you said... well whenever I turned the car off then on back again, it would go back where it was... Even without the screw holding it inplace. I'm lost

I just put my car back together and messed with the trimming and it's going straight enough for me

Later.
