I just installed my new jr z3550 servo into my 12th scale and tried to center the servo saver by loosening the small center screw in the center of the splines and now when I turn on my car the servo goes all the way to the left. Any ideas? Anyone know how to do this properly?

Nevermind, figured it out Like a dumba$$ I was loosing the screw all the way off when the car was turned off. Finally dawned on me that the car has to be on and the splines move relative to the screw,oops.lol
