Servo, Steering problem

[Xtreem]

I have a Nissan Skyline Xmods and it's not even a week old. My problem is that the car turns further to the left than the right, yet it still runs straight. :/

Also, my server makes a twitching noise a lot... sometimes i'll move the car a little and the noice will stop temporarly. This is extremely annoying. Is there a way to fix it? or what causes it? I have also noticed that my "Command Logic" lights are flashing very fast when this noise occurs.


I have followed a guide to center my servo. But this seems to do nothing.

My upgrades include;
AWD
5 Cell Upgrade

I would really like to hear an explanation for this.

Thanks!
